WPC terrace board: production, characteristics, installation methods. Do-it-yourself liquid tree - we create wood-plastic at home

History of the KDP

The technology for the production of wood-polymer composite was developed back in the 70s of the 20th century with the aim of more effective use a large number wood waste. At the same time, the first material production plant appeared in Sweden. But since the technology was imperfect and the equipment wore out heavily during the production process, the experience did not become successful.

At the end of the 20th century, American manufacturers became interested in the technology. Traditional for private buildings terraces (flooring) were previously assembled from wood. But such designs required constant care and did not differ in durability. Plastic, which could also be used for the construction of terraces, was expensive in those days. Therefore, the material, which was half wood waste and half plastic, became a real find for all builders and ordinary homeowners.

At the same time wood-polymer composite began to be actively used in Japan. They covered balconies and terraces. And in China, even sidewalks, garden paths, benches and gazebos were made from WPC

Currently composite materials literally conquer more and more new areas. The growth of the WPC market in the world is 20% per year, production technologies are being improved and become even more economical and safe for humans and environment. And the material itself acquires new properties and in certain areas confidently displaces both wood and plastic.

Wood is perhaps the most popular building and finishing material. Wood is versatile in processing, has high thermal insulation and aesthetic qualities, is indispensable for creating unusual architectural buildings, exquisite furniture, interior decoration and home gardens. The only drawback of the tree is susceptibility to adverse external factors and the ability to decay.

In an effort to preserve all the advantages of wood and negate all its shortcomings, manufacturers have created an innovative construction material- wood-polymer composite. Let's consider what "polywood" is, what properties and characteristics are inherent modern material and what is its scope.

The main types of wood composite materials

Wood composites are materials obtained by combining different raw materials. The main component of a wood composite is wood. The amount of wood waste, as well as the type binder component determine the main characteristics of the composite material.

The most common wood composites are:

​

Let's take a closer look at the composition innovative material, technology of its production and technical and operational characteristics.

Wood-polymer composite: production and material composition

The WPC consists of three main components:

1. Particles of chopped wood (some manufacturers add particles to reduce the cost of production rice husk or cake of seeds).
2. Thermoplastic polymer (polyvinyl chloride, polyethylene, polypropylene).
3. A complex of modifiers - chemical additives (up to 5% in the composition of the material).

The production of wood-polymer composite proceeds according to the scheme.

Chopping wood. The wood is processed on hammer and knife crushers to obtain particles of 0.7-1.5 mm in size. After crushing, the wood is screened and fractionated.

Profiles without surface finishing are made from the smallest fractions, profiles for finishing with veneer, paint or film are made from medium components, and coarse wood fractions are used to create technical profiles

Drying wood carried out if the moisture content of the raw material exceeds 15%.

Dosing and mixing of components. All components of the WPC are combined in the right proportions and mixed with each other. The most commonly used ratios of wood flour/polymer components are:

• 70/30 - in the composite there is such a property of wood fibers as moisture expansion; WPC is considered more fragile and has a service life of about 5-7 years;
• 50/50 - the optimal ratio of wood and polymer, which preserves decorative properties wood and polymer strength;
• 40/60 - the aesthetic qualities of wood weaken, the material feels and looks like plastic.

Pressing and formatting of the product. The final stage, at which technical properties WPC and the material acquires a presentation.

Technical and operational characteristics of wood-polymer composite

The properties of the composite are determined by the amount of wood in the material, the type of wood and polymer used. We note the general mechanical and physical characteristics of the WPC:

1. The density of the material. The value depends on the base resin used, the amount of additives used and the density of the wood particles. The maximum density of WPC is 1.4 kg/dm3 (true wood density).
2. Tensile elongation - 0.5-1%;
3. Bending resistance - 25-60 MPa;
4. Impact strength according to Charpy - 3-4 KJ/m2.

The wood part of the WPC gives the material the following properties:

The polymer qualities of WPC are manifested as follows:

Comparative characteristics of wood and WPC

In order to more clearly characterize the wood-polymer composite, we will conduct a comparative analysis of the main qualitative and economic indicators wood and WPC.

Scope of WPC

Due to its merits, wood composite won wide popularity in the industrial sphere, construction and in everyday life:

More than 50% of the wood-polymer composite is used as "decking" - wooden planks and tiles for decorating coastal and backyard architecture

Product overview of the main manufacturers of WPC boards

WPC decking boards are represented on the construction market by many manufacturers. When choosing a material, it is better to give preference to well-known companies - their product has already passed the test of time for quality and has gained a positive reputation around the world.

Terrace board bruggan(Belgium) is made from high quality raw materials, products are oriented to the international market. According to the textile sensations, the board is as close as possible to wood.

The Bruggan board has the following composition:

• tree - 60%;
• polymers - 30%;
• additives - 10%.

The company produces hollow and solid decking boards, which are used for arranging areas around swimming pools, creating terraces, summer areas of hotels, bars, restaurants, and building stairs.

Solid decking board Bruggan Multicolor has a wood texture throughout the thickness of the material, suitable for sanding and radius trimming

Estimated price of a Bruggan board is 1000-1200 rubles per profile

Terrace board Mirradex(Malaysia) is made from fibers of tropical trees, which increases the resistance of the material to moisture. The board does not require additional processing. The structure of the board is double-sided - this allows the material to be used to create vertical structures (fences, railings).

Mirradex board composition:

• wood - 50%;
• polymer (polypropylene) - 40%;
• additives and various additives - 10%.

Terrace board Mirradex belongs to the category of premium materials, but at the same time it has a relatively affordable price (about 750 rubles per profile).

Terrace board Legro(Hungary) has a special protective layer that increases the wear resistance of the material. The Legro board is suitable for arranging terraces and areas in in public places with increased permeability.

Advantages of the Legro board:

• does not burn out;
• no stains remain on the surface;
• resistance to damage (scratches, dents);
• double-sided indelible texture.

Composition of WPC Legro:

• chopped wood - 50%;
• polypropylene - 45%;
• additives - 5%.

You can buy wood-polymer composite Legro at a price of 3500 rubles for one profile measuring 150 * 25 * 5800 mm.

"Liquid Tree": making your own hands and using it in everyday life

At home, you can create an analogue of a wood-polymer composite with your own hands. As a result of the work, a “liquid tree” will be obtained, which is suitable for the restoration of furniture from chipboard, repair parquet board and laminate.

The whole process of making a homemade "liquid tree" can be divided into the following steps:

• Grind sawdust with a regular coffee grinder.
• Combine the resulting flour with PVA glue. Component ratio: 70% - wood, 30% - glue. "Liquid tree" should have a thick consistency.

The resulting paste is applied to the damaged area of ​​​​furniture or flooring, and left until completely solidified (about 4-5 hours). After that, the excess "liquid wood" must be cleaned with sandpaper.

To give the "liquid tree" the desired shade, a dye intended for water-based paint can be added to the mixture.

The advent of wood-polymer composites made it possible to combine the most significant advantages of wood and plastic in one material. Buildings and structures made of WPC are easy to install, have excellent operational characteristics and have an aesthetically noble appearance inherent in natural wood products.

Greetings friends, Andrey Noak is in touch with you. Surely, you thought about the fact that almost every material has its own service life. For example, wood does not withstand all the effects of aggressive natural factors. As a result, designs, products from it often become unusable too soon.

Understanding this humanity, constantly trying to find worthy alternative. And relatively recently, in the catalogs of the respective companies, you can see such an offer as WPC. Wood-polymer composite - what is it, what advantages does it have, for what purpose is it used? In the article, I tried to answer the above questions in detail. Take just a few minutes of your time to read this article and you will definitely not regret it.

Such material is also called. This is the latest development, which was carried out by specialists chemical industry. The PDK managed to unite positive traits both wood and polymers. The board consists of the following components:

1. Wood flour. It is made on modern equipment that is capable of grinding material. Not required to use quality wood. Often, recycled products are used instead. It does not matter at all what kind of wood is used, since it practically does not affect the positive properties.
2. Polymer. As a rule, polyvinyl chloride or polyethylene is most often used. Percentage directly depends on which polymer is taken. Proportions affect quality, and therefore you need to take the optimal amount of such a component. Too low a percentage of the polymer will cause the material to begin to absorb moisture and simply deform over time. If, on the contrary, the norm is exceeded, then such a product will take on the form of standard plastic.
3. Chemical additives. The board will not have all the possible advantages, if you do not provide for the presence of some chemicals in the composition. But, at the same time, such additives will not have a negative impact on human health. That is, they are completely safe, which is extremely important.

It is interesting to note that the production of such material, as much as possible, resembles the process of processing ordinary wood. Here you will also have to perform operations such as sawing, planing, grinding. Next - screws are screwed in or nails are hammered.

Benefits of WPC

It would be foolish to talk about the material in the absence of positive qualities. There are quite a lot of them, I will not list the most significant of them:

• Resistance to moisture, which cannot be said about;
• wear resistance; the surface of the material is not erased, does not lend itself to any mechanical damage, even if you constantly walk on the board in thin female heels; there are no scratches, cuts, dents;
• The wood-polymer composite is distinguished by the fact that it is non-slip, respectively - in winter you can move along it without any fear;
• The ability to withstand a wide range of temperatures - from about -50 to + 150 degrees Celsius;
• With polymers and chemicals, which are part of the material, there is no threat of the appearance of fungus, mold, and insects will not harm;
• Ease of installation - it is not necessary to be a professional experienced person in order to do all the necessary scope of work with your own hands;
• Ease of care, since there is no need to occasionally varnish or paint, and even more so after a while to grind or scrape the surface;
• Long service life - manufacturers give guarantees that are measured in tens of years, although if the floor is used natural wood, then often after 5-7 years it will be necessary to carry out certain restoration procedures - painting, minor repairs.

You can probably guess what they managed to invent practically perfect material. If we talk about the shortcomings, I can focus on the cost and partly on environmental friendliness. Unfortunately, the price cannot be called low. Although, on the other hand, they consider it completely justified. If the product is different big amount advantages, it a priori cannot be cheap.

Application area

A lot of things are made from WPC. For example, material for a fence is actively used. The board will turn out smart decision in cases where it is not entirely advisable to use ordinary wood. Saunas, swimming pools, piers, underwater piles - everywhere you can find a place for a wood-polymer composite. Even for beds, you can use such material.

Companies make gazebos, some interior and exterior items from DKP. If it is necessary to decorate the territory decoratively, then the wood-polymer composite will also not be superfluous. For the facade, it is advisable to use the material for those who prefer not only a beautiful appearance, but also reliability and wear resistance.

In general, you can talk for a very long time about the possibilities of using such boards. Moreover, new options are constantly being found where the material could be used.

Summing up, I want to note that the acquisition of the PrEP will be 100% a reasonable decision. Don't look at the cost first, as it's a little higher than the price of regular wooden products. There are always advantages and disadvantages to consider.

I tried to convey useful information and I'm sure it will definitely help. By the way, wood-polymer composite is used even for siding.

Good luck and see you again, Andrey Noak was with you!

Modern building materials should be not only aesthetic, but also practical, easy to handle and maintain, and most importantly, economical. Many enterprises work in the field of invention of new materials, directing research mainly on combinations various substances, and among them one can single out such a promising novelty as wood-polymer composite (WPC).

DPK is often referred to as liquid tree , or wood-plastic , and those who like to flaunt their knowledge of English call it polywood . From these names it is clear that it is a combination of plastic and wood in a molten state, followed by solidification of the final product. Liquid wood is an alternative to expensive wood varieties, and, in addition, has significantly improved performance compared to any wood or plastic. In the light of modern fashion environmental materials wood-polymer composite- this is a necessary improvement in materials used for cladding, flooring, the manufacture of panels and "boards" and many other building and finishing materials. Wood-polymer composite has received the widest application in the field of manufacturing terrace boards (decking).

The most popular WPC application is decking or decking.

Properties and characteristics of wood-polymer composite

WPC consists mainly of wood fibers, the role of which is successfully performed by waste from the woodworking industry and plastic as a binding substrate. As a result, the resulting material combines all beneficial features modern polymers and natural wood.

Woody qualities of liquid wood are manifested in:

• authentic wooden pattern, texture and color;
• similar thermal conductivity;
• characteristic aroma;
• safety for the environment and for the consumer.

The polymeric part of the WPC gives it such properties as:

• high moisture resistance, because of which you should forget the problem of swelling boards;
• strength and wear resistance, thanks to which WPC products are not afraid of loads, impacts and constant abrasion. Shoes, animal claws, falling objects do not leave visible marks on the surface. In addition, even when wet, the WPC decking does not slip, which is so important when used on the floor, as steps and, of course, terraces, verandas, outdoor areas and even (garden parquet);
• heat resistance and ability to withstand extreme weather conditions;
• inedibility for insects, fungi, and putrefactive bacteria;
• ease of processing and installation (an example of the construction of a WPC terrace);

As a result, liquid wood, unlike all known building materials, simultaneously:

• Reliable, durable and beautiful;
• Requires no maintenance other than dusting. Scraping, varnishing, paint coating and other manipulations are the whims of the tree, the wood-polymer composite simply does not need them;
• Economical. There is simply no point in comparing WPC with natural wood in terms of cost, and plastic becomes more expensive over time due to the fact that it requires frequent repairs and replacements. That is, a wood-polymer composite that will easily serve you for a quarter of a century will survive several changes in plastics and wood, due to which its cost in the overall account decreases several times.

The variety of WPC products is truly limitless.

Scope of wood-polymer composite

Such undoubted advantages have led to the use of WPC in the field of construction and even interior decoration cars and yachts, and because of its excellent water resistance, it is used for the construction of structures that often come into contact with water or are constantly in it: the sides of pools, piers and piers, small bridges, some details of shipbuilding and even sea piles (!).

In private housing construction, wood-polymer composite becomes the No. 1 material when installing various floor coverings, garages, dance floors, verandas, terraces and fences. In addition to everything, excellent garden structures are obtained from liquid wood: gazebos, terraces, paths, fences, gates - and all thanks to resistance to a wide temperature range, ultraviolet sunlight and influence of living organisms. And what kind of facade cladding can be done with the help of WPC!

Lightweight, heat and moisture resistant, easy to install and, moreover, environmentally friendly wood-polymer composite becomes an excellent replacement for eurolining and. It also makes excellent window sills and countertops, furniture and doors of any type (both entrance and).

The most widespread in the world WPC building material - decking, also called terrace board. From decking create floor coverings in interiors, as well as in rooms where humidity is often increased: a bath, a sauna, a bathroom. All the positive qualities of WPC work when used for exterior finish structures: the already mentioned balconies, terraces, exploited roofs, verandas, piers, piers and decks of ships.

Terrace board is a traditional profile product with variable configurations. Manufacturers also recommend using a hollow or solid decking profile for different types expected load on the coating.

Also very common is a WPC product called garden parquet. Outwardly, it looks like tile flooring with segments of about 30 by 30 cm. But the parquet itself is made up of a plastic substrate, to which the planks of wood-polymer composite are attached. Special fastenings of the underlay make it easy and simple to install and reassemble the flooring, which makes it suitable for use in seasonal buildings, playgrounds or private suburban areas.

Where did this amazing material come from?

Created a wood-polymer composite (WPC) in Italy. Back in 1974, the ICMA San Giorgio concern received a patent for the authorship of this building material, for which it was created trademark wood stock. Now you can clearly see all the prerequisites for such an idea - after all, the company was previously engaged in both traditional woodworking and the manufacture of polymer plastic products. The costly waste disposal of both industries has become a problem that has been economically solved by combining both directions. But then the new building material was not just a novelty, but stood on the verge of fantasy, so he had to earn the trust of consumers for a long time.

WPC production technology requires careful observance technological process And High Quality raw materials. The processes of refinements and improvements in manufacturing technology, and then the material itself, dragged on until the eighties. And the liquid tree received consumer recognition not in Italy, but at the largest car factories in the world. Now almost everyone deals with WPC, but they may not even be aware of it, because most car interiors are made from it - a wood-polymer composite.

Wood-polymer composite - manufacturing in production

Composition and production of wood-polymer composite

If we consider the composition of WPC in more detail, then its changes can be traced from the beginning of production to the present, and now it is something like this: crushed wood filler, which gives the main volume to the product, is bound by one of three types of polymer. purpose finished product determines the choice: polypropylene, polyvinyl chloride (PVC) or classic polyethylene. Plastic with filler bind and turn into a single monolith.

Additives are actively used in the manufacture of liquid wood - various additives necessary to give the composite the desired performance properties. Their role in the liquid tree is played by products of the chemical industry:

• colorants to give color;
• modifiers to enhance strength and hardness;
• lubricants for better moisture resistance and faster extrusion;
• foaming agents to give lightness and smoothness to the surface;
• biocides for maximum resistance to the effects of biological factors.

Disadvantages of wood-polymer composite

The disadvantages of wood-polymer composite materials include poor tolerance with constant simultaneous exposure to combinations of two negative influences- high humidity and high temperature, which leads to rapid wear of the WPC coating.

The appearance of mold with insufficient ventilation of the room, with which only specific and expensive additives can be combated. Its cost compared to the budget tree is still the main disadvantage.

The closest natural competitor of WPC can be larch or the rarer bankiraya tree (Bangkirai), which sometimes costs even half as much, and has almost identical properties. The difference appears only in those places where the use of one material is impossible and it is replaced by another.

Technical and operational characteristics of wood-polymer composite (WPC) and larch

Larch will perform much better in a bath or sauna (high temperatures combined with humidity - remember?), But the wood-polymer composite will last much longer outdoors, since wooden building materials in the air always need regular additional processing and replacement.

Wood and plastic are well-known and widely used materials, each with its own pros and cons. Until recently, the disadvantages of using plastic and wood have been minimized by special additives and impregnation, but modern technologies allow you to create completely new, revolutionary materials. One of them is called wood-polymer composite (WPC), or simply liquid wood.

In fact, a wood-polymer composite is a cross between wood and plastic. It is made from crushed wood with the addition of polymers (polypropylene, polyvinyl chloride, etc.) - the particles of the materials are mixed, after which, under the influence of high temperature and pressure, the mass is given the appropriate shape. The content of wood in the material can be up to 90%. In this combination, the duodenum acquires positive properties wood and plastic, and its use provides a number of advantages.

WPC - composition

Like any other material, wood-polymer composite has a number of disadvantages that should be considered when buying and installing it.

Based on all of the above, WPC has much more pluses than minuses, and in the future its price may significantly decrease, since waste from the woodworking industry can be used to manufacture the material.

Well-known manufacturers of WPC facade boards:

• DeckMayer (Germany);
• TM Tardex (Finland);
• EcoDecking (Russia);
• Legro (Hungary)
• Eternal tree (Russia).

Wood-polymer composite products

The range of products that can be made from WPC is not the most extensive today, since the properties of the material have not been fully studied, but all products have already gained considerable popularity among consumers.

In addition, WPC products are often used for the manufacture of fences, railings and small architectural forms(for example, gazebos). They have good bearing capacity and can be used in crowded places.

A board made of wood-polymer composite can have different colors and shades, be absolutely smooth or have an embossing that completely imitates the structure of wood. This allows you to implement any design solutions, as well as select a board, taking into account the peculiarities of the architecture of the building and the surrounding landscape.

How to choose a facade board from WPC?

For the manufacture of a facade board from WPC, wood flour is used, the quality of which has no special significance, but special attention should be paid to the binding components. Material based on polyethylene and its derivatives is quite cheap and contains a large amount of wood, but at the same time it is highly susceptible to fading in the sun. Another type of material that is made with using PVC, more resistant to temperature extremes, ultraviolet and fire, and also twice as durable as analogues.

Step-by-step instructions for installing a WPC facade board

Proper installation of wood-polymer composite is the key to durability, reliability and attractive appearance of the finish. The facade made of WPC panels and boards belongs to the so-called ventilated facades, which have a number of advantages over other structures. Despite the fact that the installation process in this case is quite simple, it requires compliance with some important rules.

1. A WPC board is not recommended for cladding buildings made of hollow materials (for example, aerated concrete), as it requires the installation of a massive frame that can damage the walls.
2. Store material should be stored in a dry place in horizontal position so that the board does not bend. If it is stored outdoors, the boards must be covered with an opaque material.
3. Do not pay attention to the fact that between individual elements there may be slight differences in shades. This may be due to the use of different raw materials and WPC processing technologies, but it ensures that the finished surface will have a natural look.
4. Before proceeding with the installation, it is advisable to place the material for 72 hours so that it has time to acclimatize. Work can be carried out at temperatures from -10 to +35 degrees.
5. It is very important to use only high-quality hardware, preferably galvanized or stainless steel.
6. Before installing WPC panels, it is necessary to install a rigid frame made of composite logs, galvanized or aluminum profiles on the building. It is not recommended to use wood for this purpose, as it is too exposed to atmospheric influences and can lead to deformation of heavier WPC panels. If you need to mount wooden grate nevertheless arose, you need to choose durable wood processed in the factory (for example, bog oak).
7. The wood-polymer composite is not suitable for operation in closed areas and in places with high humidity(for example, in baths).
8. Cladding with wood-polymer composite panels should not be made directly from the ground, but only from the basement of the building.
9. It is better to buy additional elements for decorating the finished facade from the manufacturer of the material. If this is not possible, their technological and design features, otherwise they can spoil the appearance of the facade or even make it less reliable and durable.
10. Before installation, be sure to check the material for damage and cracks.

One more important point is that during installation it is necessary to maintain the distance necessary for the thermal expansion of the material, which depends on the environmental conditions.

The installation of WPC panels is carried out in several stages, each of which is very important for the final result.

Stage one. Preparation of tools and materials

In addition to panels made of wood-polymer composite (the calculation must be carried out taking into account the area of ​​\u200b\u200bthe facade plus 10-15%), the following materials will be needed for cladding:

In addition, to perform the work, it is necessary to prepare a number of tools, including:

• electric drill;
• perforator;
• screwdriver;
• manual circular saw;
• hammer;
• level (length not less than 60 cm);
• metal scissors;
• joiner's square metal;
• ruler, tape measure, pencil.

Stage two. Surface preparation

Before mounting WPC panels on the walls, they must be prepared accordingly. All unreliable or worn surface elements should be removed, replaced or cleaned. If there are remnants of the old coating on the walls (for example, plaster), they must be removed and, if possible, removed drainpipes, fixtures for fixtures and protruding window sills.

The walls should be cleaned of dirt and dust, and treated with means to prevent the development of harmful microorganisms and fungal spores. Work can only be carried out on condition that the surface is solid, clean and dry.

Stage three. Frame installation

The frame is a very important part of the hinged ventilated facade, on which the durability and reliability of the entire finish depends. First of all, you need to make a project and develop wiring diagrams so that the crate is installed appropriately, after which you can proceed directly to the work.

The frame can be mounted in three ways: using aluminum profiles (well processed and dried wooden beams), wood-polymer profiles or L-shaped brackets and profiles.

Option number 1. aluminum profiles(wood). The advantages of such a frame are ease of installation and low cost. For the crate, it is not recommended to take an untreated or wet timber, as there is a possibility of the entire structure being skewed.

Option number 2. WPC profile. A fairly simple and reliable frame, which is mounted to the walls with the help of dowel-nails.

Option number 3. L-shaped brackets or profiles. Universal design, which makes it possible to use insulation of any thickness, and L-shaped profiles compensate for all drops and distortions of the surface. The facing material in this case is attached to the frame with the help of clamps.

The sequence of actions when installing a frame from a profile for a ventilated facade is as follows.

Step 1. Determine the installation height of the facade along the perimeter of the wall, as well as vertical and horizontal levels.

Important: at the joints of the panels, a wider profile must be installed (you can use two intermediate elements installed side by side).

Step 2 Using a pencil and a level, mark the walls vertically - it will serve as a guide for mounting the brackets, and the interval between the marks should be 30-50 cm.

Step 3 Attach the brackets in one vertical line, starting at the corner of the building. Installation is carried out as follows: holes are drilled on the surface at intervals of 40-60 cm, then brackets are attached using anchors or dowel-nails.

The extreme rows of elements are installed at a distance of no more than 20 cm from corners and slopes. Above and below the facade, the brackets should be mounted horizontally, the distance is 10-15 mm from the wall.

Step 4 Attach the first profile to the brackets (again, you should start from the corner of the building), then screw the second profile on the other corner, aligning them in one line. Next, attach the brackets to the entire wall, except for window openings, and fasten the profile to them, constantly checking the evenness of the frame. It is recommended to fasten the profile with two self-tapping screws to each bracket, screwing them into pre-drilled holes.

Step 5 In a similar way, assemble the frame for the remaining walls, and then install the end, corner and docking strips in the right places so that the structure is a single whole.

The wooden crate is mounted in the same way, only instead of brackets, ordinary logs are used, which are attached to the wall with screws.

Stage four. Insulation installation

Installation of insulation is carried out if it is planned by the project. Insulation allows you to get rid of the so-called cold bridges that form between the frame and the wall. The choice of method depends on which type of material was chosen, since each of them has its own styling characteristics.

Important: a special membrane with a vapor barrier effect must be placed under any insulation and on it. As a result, it should be as if packed in a membrane bag - without this, the material can get wet and completely lose its properties.

1. Basalt or mineral wool fastened to the surface using dowels made of plastic with wide hat. First you need to drill holes in the surface to a depth of 5-6 cm, then insert the dowel there and fix it with a spacer nail. On the square meter material is taken about 6 dowels.
2. For polystyrene foam and polystyrene foam, glue is used, and the material must be laid in at least two rows, and the joints must be foamed. This best option for residential buildings, providing complete thermal insulation.

The thickness of the insulation should be equal to the thickness of the frame elements so that the finished cladding does not deform or sag. Important: to insulate a ventilated WPC facade, it is not recommended to use cheap and low-quality material, as they tend to caking, which is why they cease to perform their functions, and fungi and mold can begin to multiply under the facade.

Stage five. WPC board installation

To fix the WPC board on the frame, special clips and self-tapping screws and screws are used (recommended length is 20-25 mm, width - 2.5-3 mm), as well as clamps. Installation must start from the bottom corner of the building and continue horizontally, laying the boards in rows, and it is important that there are ventilation joints between the wall in its upper and lower parts and the mounted facade for ventilation.

Step 1. Drill a hole at the very bottom of the frame, and its diameter should be slightly larger than the diameter of the self-tapping screw.

Step 2 Insert the front board, fix it with a clip and a self-tapping screw, screwing it as perpendicular to the surface as possible so as not to damage the material. When tightening the screws, do not use too much force, as this can cause deformation or cracking of the board. It should not “sit” too tightly, otherwise, with thermal expansion and contraction of the material, the facade may crack.

Note: if clamps are used to fasten the board, make sure that they fit snugly, but without effort, into the longitudinal grooves.

Step 3 Insert the retaining clip into upper part boards of the first row and install the next board, securing it in the manner described above. Each panel is recommended to be fastened to the profile with two self-tapping screws, and special attention should be paid to the joints of the profile and the board (in these places the fastening must be especially strong). The subsequent upper rows of panels are best mounted with a slight offset of the seams.

Step 4 For the finishing row, the boards, if necessary, must be cut, and when fastening, provide a technical gap of at least 10 mm wide between the adjacent surface and the edge of the board.

Installation option for DKP siding without clamps

Step 1. Having slightly bent the panel in the center, apply the ends of the panel
castle parts

Step 2

Step 3

If it becomes necessary to dismantle the panel, the work should be done in the reverse order: pull out the screw and carefully remove it with a hook. To make the design look aesthetically pleasing, corners and joints can be closed with special additional elements.

Care of the facade from the WPC board

The wood-polymer composite facade does not require any special care– you can wash the surface with a hose, and clean with simple household products. Strong contamination is best removed immediately, and for this it is allowed to use a sink high pressure(maximum 80 bar, minimum distance from the surface - 20 cm). Grease and oil stains are removed with household chemicals which is suitable for wooden and ceramic surfaces using a medium hard brush. After the procedure, be sure to rinse the facade with water.
