Ventilation pipe on the roof ondulin. Pass-through elements VILPE. The nuances of installing ventilation systems

The conclusion of fittings and pipes for any purpose on the roof is not an easy task. If leaks occur in the roof, then most often the cause of moisture in the subroofing layer is precisely the junction and the transition element that closes the space between the ventilation system and the roofing material. And in the case of using ondulin, the situation is complicated by the excessive "tenderness" of the roof.

How can a pipe be brought out of the ondulin through the roof

In any residential building, at least a couple of pipes have to be brought to the roof: a stove, or a chimney, and a ventilation one. On a conventional roof, the need to remove the pipe has always been associated with the need to comply with fire safety rules, provide for the presence of thermal gaps and ensure reliable protection from the penetration of moisture into the thermal insulation layer. If you have an ondulin roof, you will have to take into account additional factors:

• Roofing material made from pressed cellulose fiber and bitumen is extremely flammable, even if flame retardant impregnations have been used. Even sparks flying out of the chimney can cause a fire;
• Save condition mechanical strength ondulin canvas is to provide full support for the edges, otherwise the material will be deformed;
• As the temperature rises, the material begins to soften and lose mechanical strength.

Advice! Most in a simple way to gain experience in arranging air ducts on the roof from ondulin is to perform work on installing a ventilation system in the manner proposed by Ondulin specialists.

Methodology of the company Ondulin

The easiest way to remove the ventilation pipe and fix it on the roof is to use a proprietary through element from polyvinyl chloride, the so-called ondulin ventilation pipe, you can buy it at building supermarkets, for example, "At Petrovich".

Removal of the ventilation pipe when installing the roof from ondulin

Before laying the last row of ondulin sheets, determine the exit point of the ventilation duct to the roof. As a rule, air ducts are located in the last row of the coating. We install the passage element at the exit point of the ventilation duct in such a way that the lower edge is fixed with an overlap on the ondulin sheet of the previous row. The overlap of the element on the sheet of the bottom row must be at least 17 cm.

Fasteners are made by stuffing nails into each wave of the element. Then we fix sheets of ondulin on the sides of the passage element in such a way that an overlap of at least one wave is ensured. A web with a minimum overlap of 17 cm should be whipped onto the upper edge of the transition element. The upper edge is also fastened with nails in each wave.

Arrangement of the passage of the ventilation duct to the roof after completion of roofing work

Often it is necessary to install a ventilation pipe on the roof after the roofing is completed. If it is impossible to dismantle the ondulin sheet and arrange the output in the manner described in the previous paragraph, you have to act in a radical way:

For your information! The angle of the roof slope does not always coincide with the angle of inclination of the base of the apron to the ventilation pipe, especially if a standard type element is used. In this case, the adapter will have to be made independently from a copper or lead sheet.

Arrangement of the adjoining zone of the ondulin to the chimney or chimney

In addition to providing high-quality waterproofing, in order to properly remove chimney through the roof, fire safety requirements must be taken into account. In this case, the chimney can be dressed in an additional outer casing made of steel, a layer of thermal insulation is laid inside, which ensures that the outer shell is heated no higher than 40-50 ° C. The result is a sandwich pipe through ondulin.

In addition, in places adjacent to the chimney, it is necessary to make a continuous additional crate that will support the edges of the canvas and the transition element. The crate beam must be removed from the side surface of the chimney walls at a distance of 3-4 cm, and from the top at a distance of at least 5-10 cm.

The junction from the bottom side is equipped with a covering apron, while the surface of the transition element must go over the ondulin web on the left and right for at least one wave. The apron cover is nailed over the ondulin coating with nails into an additional crate, while the nails do not beat in the extreme waves. At the corners of the laid element, sealing is carried out with the Onduflash tape.

To the left and to the right of the chimney, a “side connection” element is installed on the ondulin sheet. It must be measured in the same way as the previous apron, cut and installed on the junction line and nailed.

The adjunction of the upper edge is sealed with Onduflash tape, using the same material, the upper edges of the aprons, which are laid on the vertical surface of the pipe, are glued. The upper edge of the tape is fixed with an additional metal bar and self-tapping screws. Along the edge of the metal strip, the gap must be sealed with polyurethane sealant. The Onduflash tape, pasted over the top edge of the chimney, must be covered with an additional piece of ondulin and nailed.

Conclusion

The easiest way to install a pipe on the roof is the method proposed by Ondulin specialists. This method works great with brick pipes, for metal and cast-iron chimneys, it is possible to pass the pipe through the roof through the “pipe in pipe” system, as the most fireproof.

Peculiarity roofing system that, regardless of roofing material, which was chosen by the developer, it includes several additional elements. For example, they can be snow retainers, a chimney or roof windows. And it also happens that natural ventilation for pitched roof not enough to bring out a large number of condensate. In this case, it is necessary to install a ventilation pipe.

In this article, we will consider ondulin as a roofing material, and learn more about how to make ventilation outlet for ondulin. Some installation details will be considered ventilation systems, as well as types of ventilation ducts.

Features of the installation of the ventilation system

Many people know the fact that ventilation can be natural or forced. Natural ventilation does not have any special devices on the roof surface, since the process is based on physical laws. Air gets under cornice overhangs around the perimeter where the air is located. These are gaps small size, which are calculated depending on the area of ​​\u200b\u200bthe roof slope. The larger the slope, the higher the gaps should be. Then the air exits through ridge element. It is also called the cold triangle.

It also happens that natural ventilation cannot cope with the ventilation process: air treatment and removal of moisture from the attic. In such cases, devices are installed that create forced ventilation. Most often, such devices are bought together with roofing material, in our case it is ondulin. Thanks to this, maximum docking is achieved. In fact, ondulin roof ventilation is not so difficult. It is only important to understand how it works. Roofing material and ventilation pipe must be combined with each other. If this is not the case, then small gaps cannot be avoided. Then moisture, waterproofing and roofing cake will start to break down.

If we talk about pipes for forced ventilation for ondulin, then they are made standard size 0.7x0.48 m. The main raw material is ABS copolymer. An example of such a ventilation system for ondulin can be seen from the video.

Learn more about how to complete all the arrangement work ventilation pipe for onlinedulin we will look below. It should only be noted that the process is carried out with great care and with strict adherence to the instructions. It is important to prevent depressurization and leaks that will affect building materials and roofing cake in general. At the same time, work on creating ventilation in a single line may differ. For example, the installation of a ventilation pipe can be carried out at the stage of creating a roof from ondulin, or after all sheets of ondulin have been laid for a long time. In this case, the algorithm of actions will be different. Just before we start looking at the instructions, let's look at what ventilation can be used for.

Varieties of ventilation pipes

Regardless of which roofing is used, the ventilation system may differ in its features.

The following is a list of what channels can be used for:

Now, let's look at step-by-step instructions from which we will learn how a ventilation pipe can be installed on an ondulin roof.

Step-by-step instructions for roof ventilation from ondulin

To begin with, consider the most common option for introducing a ventilation pipe for an onduline roof. We are talking about the original roofing material. The installation process is carried out in the usual way. Immediately before laying the last row of ondulin sheets, you need to determine the exit point of the ventilation duct on the roof. Indeed, most often the air duct is installed in the last or penultimate row. roofing material. Further instructions are as follows:

That's all, the work on the installation of the ventilation pipe for ondulin has been completed, as well as the arrangement of the roof as a whole. We recommend watching this training video, from which you can clearly see how you can do all the work on installing ventilation in ondulin with your own hands.

Installation of ventilation on the laid ondulin

Very often there is a situation in which you have to deal with installation on already finished roof. No need to be afraid because this work also uncomplicated. Usually, the ondulin sheet is dismantled and all the previous steps are performed. However, sometimes this is not possible. In this case, proceed to radical actions:

1. First you need to make a hole for ventilation. The roof covering (ondulin) is cut. In this case, the incisions are made using the cruciform method.
2. The edges of the resulting cutout are brought down, bent and fixed with inside roofing cake. Staples or small cloves can act as fixing elements. Some people use tape.
3. An adhesive composition and a film are applied along the cut so that moisture does not get into the heat-insulating layer. In our case, you need to buy a pipe with a special transition apron. Its edges are tucked under the ondulin sheet, and the gaps in the junction area are closed with an adapter tape.
4. The apron is nailed to the slats through a sheet of ondulin and reinforced with an overlay inside the roof.

That's all, ondulin ventilation is done. Now the under-roof space, thanks to the deflector, will be ventilated and dry, preventing rotting of materials.

Summing up

As you can see from the article, the work on arranging the roof with ondulin and introducing ventilation into it is simple. And thanks detailed instructions even a beginner can handle this task. It remains to buy a suitable ventilation duct for ondulin and start practicing.

Sergey Novozhilov - roofing materials expert with 9 years of experience practical work in area engineering solutions in construction.

The company "MSK Stroy Dom" sells Ondulin for affordable prices from the manufacturer. Roofing material from the French company ONDULINE is used for roofing of private houses and frame houses.

It is a very light, flexible bituminous roofing sheet that can even be laid over old roofing. It is used in the construction of capital buildings, schools, residential buildings. Also, Ondulin for the roof is used in the arrangement of cafes, trade pavilions, construction of canopies and peaks.

Features of roofing material

A huge plus of roofing bituminous corrugated sheet is the light weight of the structure, as well as ease of operation. This allows you to quickly install a new coating without dismantling the old one. Using this system, it is possible to repair the roof of a residential building not only in summer, but also in winter. Sheets for roofing fit perfectly on a wavy surface, easily bend, take the desired shape.

Among the advantages are:

• High water repellency. The roof is completely waterproof, does not absorb moisture.
• Resistant to precipitation and temperature changes. It is equally tolerant of heat and hard frost;
• Resistant to fungi and mold. Thanks to bituminous impregnation, the material does not crack, which does not allow creating an environment for the existence of microorganisms;
• A light weight, which makes it easy to transport, mount the material;
• Does not absorb harmful chemical substances, gasoline and industrial gases;
• Suitable for collecting water for drinking;
• Easy to mount without using special technology and knowledge.

The material can withstand temperatures from -60 to +110 degrees. Bituminous sheet is considered to be very durable material, the warranty period from the manufacturer for it is 15 years, but in practice it can last up to fifty years.

The composition includes a base of cellulose fibers, mineral filler, heat-resistant resins, coloring natural ingredients. All this creates a unique texture that does not lose its beautiful appearance and durable performance over time.

Check the cost of delivery with our managers.

At the request of the consumer, qualified employees will dismantle the old roofing, install the bitumen sheet at construction sites in Moscow and the regions of the Moscow region.

Ventilation is one of the main components of the life support system country house and serves to remove moist and polluted air. The ventilation system is designed and installed simultaneously with heating, electricity and water supply systems. To bring the ventilation system to the roof from Onduvilla, special Onduvilla ventilation pipes are used.

The pipes are equipped with a standard pass-through element, protected from precipitation, and their base is adapted for installation on bituminous tiles. Onduvilla ventilation pipes are made of impact-resistant ABS thermoplastic copolymer.

Modern building technology And quality materials allow you to completely get rid of drafts and significantly increase the energy efficiency of the house. At the same time, the Code of Rules SP 54.13330.2011 SNiP 31-01-2003 "Residential multi-apartment buildings" prescribes to provide a single air exchange in residential premises, that is complete replacement total volume of air at least 1 time per hour. Requirements for ventilation of kitchens, bathrooms and laundry rooms are even higher - from 25 to 90 cubic meters. m/hour. Provide the required air exchange without effective system ventilation is impossible, which is why the ventilation pipes in country houses taken out to the roof.

The base of the Onduvilla ventilation pipe has a size of 400x480 mm, and exactly repeats the profile of bituminous tiles. This simplifies installation and completely eliminates the risk of leaks. The length of the base of the pipe coincides with the length of the bituminous shingle shingle, which allows it to be mounted on both solid and standard sparse crates.

The sequence of installing a ventilation pipe on an onduvilla roof:

1. Since the ventilation pipe retains snow and creates an additional load, the crate is reinforced at the place of its installation. Additional bars (boards) are stuffed on a plot of at least 50x50 cm.

When installing the onduvilla on a solid base, additional reinforcement for the ventilation pipe is not required.

2. The roof is being installed from the eaves to the ventilation outlet.

When installing the coating on a solid base, 13.5 cm is deposited from the upper edge of the onduvilla towards the ridge and the center of the hole for the passage element is marked. A hole with a diameter of 12 cm is cut.

3. The ventilation pipe is installed. Its base is laid on top of the mounted coating. The waves and stripes of the hydraulic locks of the base of the pipe and bituminous tiles must exactly match. If necessary, the opening for the passage element expands.

4. The cover is mounted on both sides of the ventilation pipe. bituminous tiles placed over its base. The lower part of the base of the pipe is fixed at two points at the time of installation of the onduvilla side shingles.

5. The roof covering is mounted above the outlet of the ventilation system. Bituminous tiles are laid on top of the base of the ventilation pipe. Top part the base is attached at three points at the time of installation of the top row of the onduvilla.

The outlet of the ventilation system is connected to the passage element of the ventilation pipe using a flexible duct with a diameter of 110 mm.

How to seal a chimney on a roof

Excellent tightness of the roof is ensured by the integrity of the roof. In case of violation of the thermal insulation layer, vapor or waterproofing, leaks become inevitable. The device of a chimney of any plan, of course, violates the integrity of the roofing pie.

To prevent moisture from getting inside, sealing is carried out.

Everything matters here: the chimney material - brick, metal, asbestos cement, the roofing material - from metal tiles, from ondulin, from corrugated board, the installation of a roofing pie - with or without insulation, height attic space and even the cross-sectional shape of the chimney channel.

Fluff is arranged on a brick chimney - expansion of the chimney due to thickening of the walls. Due to this, the walls of a brick product heat up much less than a metal product, and the volume of the adapter can be smaller.

Single layer hardware heat up more. Here, a heat-insulating box is required even in cases where the roofing pie does not provide for insulation.

• The device of the box is the same for all types of chimney structures.

  The subtleties of the output of the chimney through the roof

  It is constructed from bars fixed on rafter legs Oh. Since wood is classified as a combustible material, the distance between the wooden elements and the walls of the chimney must be at least 13 cm.

• From below, under the ceiling of the attic, the box is hemmed with a sheet of non-combustible material - plasterboard, galvanized iron. The space between the chimney and the walls of the adapter is filled with a heat-resistant heat insulator - a special heat-resistant mineral wool, expanded clay.

Further actions for sealing the device depend on the material of the roof.

Passage through the slate roof

It should be noted that slate is the most difficult material in this regard. For modern roofing materials, manufacturers offer ready-made waterproofing devices. These have not been developed for slate.

Waterproofing the chimney on a slate roof is carried out as follows.

1. The film waterproofing material that covers the roofing pie is cut in this area in such a way as to overlap the walls of the chimney. The film is fixed with bituminous mastic.
2. Slate is placed, trying to join the sheets with the walls of the chimney as tightly as possible.
3. A collar is made of galvanized steel - an element of the required length, curved so as to tightly adjoin the roof and the chimney. The joints are covered with collars.
4. received metal structure poured cement-sand mortar so that the sealing protrudes above the level of the flooring.

The resulting device can hardly be called decorative, but it provides good tightness.

The passage of the pipe through the roof of the metal tile

In addition to finishing material manufacturers produce various additional elements, including aprons for chimneys.

1. Waterproofing is carried out in the manner described above. This is an important part of the job, as it ensures the watertightness of the entire roof, not just the joints between structures on the roof.
2. A crate of wooden slats is formed around the chimney, and then details of a metal apron are fixed to it. The joint on the top bar is treated with an appropriate sealant.
3. The lower one is usually not sealed, as it involves the installation of a drainage tie, and in this case, the sealing will not allow water to flow down freely.
4. A metal tile is laid around the chimney. All joints are treated with a heat- or heat-resistant sealant.
5. From above, a decorative apron is mounted in the same way. Usually it is made in the same color as the roof. In the photo - a chimney with an apron.

Sealing a chimney on an ondulin roof is no different from the installation described above. The only difference is the material of the upper, decorative apron - it is made of plastic.

The passage of the chimney through the roof of corrugated board

If the material is completed with elements for sealing the chimney, ventilation ducts and other things, it is recommended to use it. The procedure in this case is the same as when sealing the roof from ondulin, and the special element, in addition, repeats the shape of the "native" corrugated board, which ensures a snug fit.

If there are no such elements, then the sealing of the chimney on the roof of corrugated board is carried out in the following way.

1. Holes are cut in the sheet smaller sizes chimney by 1.5–2 cm.
2. Cuts are made in the corners and the edges of the sheet are bent.
3. At the stage of installation of the roofing deck, the workpiece is put on the chimney, and the edges are pressed against the walls of the chimney as tightly as possible.
4. To seal the seams, a special rubber-bitumen tape is used, like Master Flash.

How to care for an ondulin roof

Ondulin refers to modern materials with high operational qualities A: It is an excellent option for the private sector. It is worth noting the low cost of the coating and the simplicity of its installation, which can be implemented independently.

What is special about an ondulin roof

As part of ondulin, there are no harmful environment components, which is achieved by using in its production the latest technologies. Ondulin sheets are made on the basis of cellulose and some additives. In order for this roofing to be rigid and waterproof, a special bituminous material, with the addition of resin. For coloring finished sheets apply special formulations, making them very aesthetic and more resistant to external influences.

Ondulin looks like ceramic and ordinary tile, or as slate. Wherein quality characteristics both coatings are not particularly different. Slate imitation is produced in the size of 200x95 cm, smaller parameters are used for tiles. Ondulin tile imitation is mainly used to decorate roofs with complex shapes, which significantly reduces the number of trimmings. Simple roofs are equipped with ondulin slate: the ease of laying the material allows you to cover the roof with ondulin with your own hands in a very short time.

Strengths and weaknesses of the material

Ondulin is very resistant to destructive atmospheric influences. It is easy to mount, resulting in a very aesthetic roofing surface. The financial cost of purchasing the material is not very large.

Ondulin has the following positive qualities:

1. Excellent environmental cleanliness.
2. Long operational period.
3. external aesthetics.
4. Rich color range.
5. Easy and fast installation.
6. Convenient dimensions, which minimizes the amount of waste, while increasing the speed of roofing.

Thanks to these indicators, ondulin has gained high popularity in the field of private housing construction. Since there are no harmful components in the material, wooden structures are often covered with it. With the help of ondulin, old roofs are often repaired without removing the old roofing. This becomes possible due to the low weight of ondulin (3 kg / m2), so a significant increase in the load on truss system and the design of the house in general does not occur.

Basically, this cladding comes with a 15-year warranty. However practical experience shows that, subject to the rules of installation and maintenance, such a roof can last many times longer. Moreover, which is important, in the process of operation, external decorative qualities coatings practically do not change, keeping the original freshness for a long time.

However, the main advantage of the material lies in the possibility of laying a roof of ondulin with your own hands. The procedure for this work is very similar to the installation of slate sheets, while ondulin is lighter, stronger and more environmentally friendly.

As for the disadvantages of ondulin, the main one is the ability of the material to ignite in the event of direct exposure to a flame. For this reason, it is practiced to treat ondulin sheets with special fire-fighting impregnations to reduce their flammability. It is also important to understand that a significant duration of operation leads to the fact that the color of the roof gradually fades: this applies in particular to dark shades.

Signs of a quality ondulin

Unfortunately, the market construction products there are quite a few low-quality fakes of ondulin.

The following tips will help you distinguish real material from fake:

• On reverse side real ondulin always has a black mesh.
• The number of waves of the original sheet is always fixed - 10 pieces.
• The waves have a stable height of 36 mm.
• The outer surface of the material has a characteristic roughness, like gauze.
• High-quality sheets are characterized by rich matte shades.
• The extreme wave is always supplied with a seal with the marking of the manufacturer.
• The material has an accompanying brand certificate and a warranty card for 15 years of operation.

In order to minimize the laying time of the material and the number of losses for its trimming, while achieving a significant service life, it is recommended to adopt several simple rules how to install ondulin. It is very important that during installation activities temperature regime was in the range from 0 to +30 degrees. The heat provokes a softening of the bitumen, due to which the sheets are deformed. Frost makes ondulin very brittle, which increases the risk of cracking when moving the installer or driving nails. Some manufacturers allow slight frosts when laying the material, but it is better not to experiment with this.

If during the installation of the roof from ondulin with your own hands it was installed hot weather, it is important to avoid stretching the sheets: after the temperature drops, the fastener installation areas may be deformed or cracked. It is best to cut ondulin with a hacksaw for wood, be sure to lubricate it with oil: this will avoid jamming the tool. A circular saw can also be used for these purposes.

It is better to refrain from using a grinder, since the place of the cut in this case begins to melt. Ondulin sheets are fixed on the crate with the help of special roofing nails included in the cladding package. The ondulin mounting scheme requires 20 such fasteners: 10 from the bottom, 5 from the top and 5 in the middle.

When arranging the crate, it is very important to take into account the slope of the slope. If we are talking about a slight slope of up to 10 degrees, a solid reliable crate made of tongue-and-groove board or plywood is used.

With a slope of 10-15 degrees on the crate, a step is made between the jumpers of 45 cm. And if the ramp is inclined by more than 15 degrees, the step of the crate elements is increased to 60 cm.

Any frame of the crate in the area of ​​\u200b\u200bthe ribs, valleys and ridges is made solid, due to the increased requirements for insulation.

Roof penetration for chimneys

How to cover the roof with your own hands - step by step installation

Stage 1. Installation of ondulin on the roof begins with equipping the rafters with a crate on top of the previously laid vapor barrier film. The same vapor barrier can be installed from the side attic space. To fill the gaps of the crate, a heater is used, closed over the rafter legs. waterproofing film. On top of the battens, a counter-lattice is arranged from slats, which makes it possible to create a technological ventilation cavity.

Stage 2. Do-it-yourself ondulin roofing installation starts from the first row, from roof slopes. It is better to choose the leeward side for this in order to avoid blowing under the roof cladding. When attaching the sheets, it is important to ensure that their lower edges extend beyond the cornice board. The ledge is selected individually: the main thing is that the water is effectively discharged outside the roof, into the middle of the gutter. In any case, the protrusion must not exceed 70 mm. When laying ondulin, they overlap on one wave. The degree of slope of the slope affects the dimensions of the longitudinal overlap: usually they are in the range of 17-30 cm. Each sheet takes 20 roofing nails, which are hammered in the center of the sheet through a wave.

Stage 3. The laying of the second and each subsequent sheet is carried out from its half, in order to achieve a dilution of the roof joints in adjacent rows. This laying scheme is used up to the roof ridge.

Stage 4. Before laying the last rows, an additional crate is mounted under the ridge profile.

For these purposes, it is best to use a standard profile made by the same company as the ondulin coating. The overlapping size of each other's profile is 12.5 cm. The roof ridge is nailed to each wave.

Stage 5. If the wall and roof structure has a docking, it is made out with a standard profile from the same manufacturer. The same principle is applied to the design of the connection sections of individual planes of the roofing surface (valley).

Stage 6. The place where the roof joins the gable board must be well protected from moisture. To do this, one of two methods is used. One of them involves bending the edge of the ondulin sheet, which is nailed to the pediment board. The second technique is implemented by laying a rectangular profile on the edge of the roof, or tongs: this also allows you to make the docking point more aesthetic.

How to care for an ondulin roof

If the process of laying sheets was carried out according to all the rules, special care behind them during operation is not required. All that will need to be done is to remove various dirt from the roof in the country house from ondulin in a timely manner so that it can last as long as possible. After a certain time, a gradual loss of the initial freshness of the color by ondulin is observed. To restore the former attractiveness of the coating, painting is usually used, using a special material for this.

As can be seen from the description, making the roof of a house from ondulin with your own hands is a quite feasible task. All that is required is to strictly follow the laying technology and some recommendations that allow an order of magnitude to increase the life of the roof.

The chimney passage must always comply with strictly defined building codes, since the Fire safety the entire residential building. Therefore, special attention should be paid to some features of the roof through which it will be equipped. In this article, experts will consider the nuances of installing a chimney passage through a roof made of ondulin.

Features of the roof from ondulin

IN modern construction quite often, such roofing material as ondulin is used to cover roofs.

Ondulin roof ventilation pipe

It is also called "Euroslate", as it is appearance similar to the usual Soviet slate, but in quality it corresponds European standards. The name of this roofing material "ondulin" comes from the French company of the same name, which is its manufacturer.
