Installation of interfloor wooden floors. The device of modern wooden floors of houses. Intrinsic specific gravity of the slab

In private low-rise construction, when constructing interfloor floors, massive reinforced concrete slabs are rarely used, preferring structures based on wooden beams. The advantage of such load-bearing structures is the relative simplicity of their construction, lightweight and sufficient strength. Next, you will find out what material is needed to create the floor, and how the installation of the structure is carried out in practice.

The scheme of the interfloor partition - from the base to the finish

The basis of the floors constructed in private houses are based on. The following types of lumber can be used as them:

timber (massive, glued);
rounded (calibrated) log;
boards sewn together with nails, bolts or screws.

The lumber listed must be made from softwood, such as larch or pine. Spruce lumber is less durable due to the high content of branches, therefore it is used as beams of short length. Beams and hardwood logs are not used as the basis of floors, having low bending strength. The use of such a material will inevitably lead to deformation of the structure under the influence of a vertical load.

To create a continuous draft surface, the beams are sheathed on both sides with a board or slabs (OSB, plywood). From the side of the lower floor, the ceiling is further formed ( plastic panels, drywall, wooden lining) On the second floor. Second floor floors wooden beams can be laid directly on the slabs, boards that are sheathed load-bearing elements floors, or on additionally installed lags.

The beams are mounted with a certain step, which causes the presence of voids between the floor cladding. This feature is used to lay materials with soundproofing and heat-saving properties into the empty space. If wooden floors separate living quarters, their thermal insulation is not necessary - noise isolation is more relevant in this case. When the interfloor partition divides the heated space with a non-residential attic, the task of reliable insulation of the floor is in the foreground.

The most reliable soundproof material is mineral wool of low density. To create a heat-insulating barrier, polymeric heaters (polystyrene, extruded polystyrene, polyurethane foam) or the same basalt wool are often used. When using mineral (basalt) wool as a heater or soundproofing material, a vapor barrier is necessarily arranged from the side of the lower room and waterproofing from above.

We calculate beams - section, step, length

In order for the wooden floor between floors to be reliable, safe in operation and withstand the expected loads on its surface, it is necessary to correctly calculate what section of the beams is necessary and with what step they should be placed. It is clear that the thicker the beam or log, the greater the bending strength they have. The strength of the entire interfloor structure depends not only on the cross section of the beams, but also on the frequency of their location. The normal step of the bearing elements of the floors is the distance from 0.6 to 1 meter. It is unsafe to place beams less often, more often it is not rational.

The strength of a beam with the same cross section decreases inversely with the distance between its supports, that is, load-bearing walls, so the thickness of the main elements wooden floors increases along with their required length. The normal distance between the supporting walls is 4 m or less. With a larger span, it is necessary to use non-standard beams with an increased cross section or reduce their pitch. Sometimes, to strengthen the floors, additional supporting structures(columns).

As beams, bars are mainly used, having a rectangular shape at the end, and the installation of the load-bearing elements is carried out so that the large side of the section is vertical. The normal sections of the bars are considered to be 16-24 cm on the vertical side in the cross section and 5-16 cm - horizontal. The boards fastened together also form a beam, but the strength of such a tandem is somewhat lower than that of a solid one. wood detail, which is taken into account when calculating the load on wooden floors. The most irrational type of lumber used as bearing beams, a log is considered that has approximately the same strength as a conditional beam, which could be obtained when processing round timber, but at the same time much more weight.

Accurate calculation permissible load on floor beams - the lot of professional civil engineers. To calculate the design strength of floors, very complex formulas which can be operated by people with special education. However, there are tables with which you can approximately select the cross section of wooden beams, depending on the distance between the supports and the step of the bearing elements of the floor. For example, with a span of 2 m between the supporting walls, a beam with a section of 75x100 at a step of 60 cm and 75x150 with a distance between beams of 100 cm is recommended. With the same distance between the supports, logs with a diameter of 13 cm (1 m step) and 11 cm (0.6 step) are needed m).

The indicated sections of load-bearing lumber are valid for an operational load on floors not exceeding 400 kg / m 2. Such a load is calculated in the case of a device on the second floor of a full-fledged living space. If the ceilings separate the lower rooms from non-residential attic, are based on a load of 160 kg/m 2 , at which the cross section of the supporting beams is correspondingly reduced. If an increased concentrated load is expected in a certain section of the floor of the second floor (installation of massive objects), additional floor beams are installed in this place.

Methods for attaching load-bearing elements to walls - reliable fixation

by the most the best way installation of wooden floors between floors is the institution of beams in special niches that are formed during the construction of walls. Bearing logs or beams are inserted into the walls at least 12 cm on each side, which provides reliable support for the ceiling. This method is relevant when building walls from any building materials - in a brick house, in a building made of building blocks or made of wooden materials.

Niches for installing beams or logs are made larger than lumber sections. This is necessary for them correct installation in nests and the possibility of exposure in one horizontal plane. Sections of the beams that are inserted into the walls are first treated with antiseptic impregnations, then coated bituminous mastic, after which they are wrapped with a rolled waterproofing material in two layers. end part beams are cut at an angle and are not insulated. This is necessary to ensure the free exit of the steam formed when the wood is heated.

The processed and protected from moisture wooden beam is installed in a wall niche so that there is no direct contact with the building material used to build the walls. From below, under a log or beam, a piece of wood treated with protective impregnations is placed, from the sides and from the side of the end, the gaps left for ventilation are filled with tow or glass wool. To increase the strength and reliability of the ceiling, every fourth or fifth beam is attracted to the bearing wall, using an anchor connection for this.

Inserting beams into wall niches is the classic way, which has proven its reliability over many years of operation. But this method of fastening the load-bearing elements of interfloor ceilings can be applied only at the stage of building a house. To fix the beams to the built walls, special metal mounts, which are a kind of case for the end of the timber. Such parts are first attached to the walls, then load-bearing elements of the ceiling are inserted into them and fixed with bolts or self-tapping screws.

The second method of fastening wooden beams is considered more technological, the process of installing floors is faster. But if we take into account the reliability of the connection, classical method, which involves the support of beams or logs directly on bearing walls, out of competition.

Creating floors between the first and second floor

The arrangement of wooden floors between floors takes place in several stages, separated by time. If the installation of load-bearing beams is done during the construction of walls, then their further rough sheathing, thermal insulation of floors, fine finishing of the ceiling on the first floor and the floor on the second - much later, when the house is built and covered.

The installation of beams is usually done when the walls are raised to the level of one floor. The masonry of the walls, made along the perimeter, and the erected load-bearing walls represent a horizontal base, on which it is convenient to lay out wooden bars with minimal adjustment to one level. First, extreme beams are installed, which are laid, not reaching 5 cm to the vertical surface of the walls. Them mutual arrangement during installation it is controlled by means of a water level or laser level. The intermediate load-bearing elements of the interfloor structure are set in a horizontal plane according to a reference point - a thread stretched between the extreme bars or a long bar installed on top.

Before installation, lumber is treated with antiseptics and solutions (over the entire surface), which reduce the ability of wood to burn. The edges of the beams laid on the walls are processed as described in the previous section. To prevent the bars from moving, they are often fixed to the walls with clamps or wire, after which the laying of the walls of the second floor continues, during which the lumber is finally fixed. Not reaching one or two rows to the final level of the walls (depending on the masonry building material used), in the same way we lay the floor of the second floor along the wooden beams. After the masonry is completed, bypassing the installed beams, and on top we form a reinforced concrete reinforced belt, which is the basis for starting the roof structure (mounting the Mauerlat).

Beams are the basis of floors, their bearing part. To make the basis for fine finish on both floors, it is necessary to create a continuous rough surface, not forgetting to insulate (soundproof) the floors and lay, if necessary, vapor barrier. This is done in this sequence.

1. We roll from below. To do this, it is better to use boards (you can not cut them), which are sewn solid across the beams, fixing them with self-tapping screws. If a layer is needed vapor barrier material(film), it is attached to the bearing beams of the floor before the formation of the roll.
2. The next stage of work is carried out from the side of the upper floor and consists in laying heat-insulating material, which fills the spaces between the beams.
3. After laying the insulation (sound insulator), we form a layer of waterproofing and sheathe the beams. From the side of the upper floor, it is more profitable to sheathe the bars OSB boards or plywood, which will immediately create the basis for laying the finishing floor material. If you use low-quality boards, you will have to additionally install logs and already form a floor covering on them.

From the side of the lower floor, a crate is made on the basis of rolling boards, which is sheathed with drywall, decorative or other finishing material. On the upper floor, flooring (laying) of the final floor covering.

The concept of overlap, in principle, is familiar to most of us. This is what separates the floors. AT high-rise buildings floors are made of reinforced concrete. Use in country houses or two-story country houses such overlays are not appropriate. Wooden floors between floors are more suitable here. We will talk about them.

Note that this type of overlap is not only reliable, but also quite affordable. And you can perform work on the arrangement of wooden floors on your own, having previously familiarized yourself with the technology.

A few words about the features of wooden floors between floors

Note that the wooden floors between floors are carried out along the supporting beams. Therefore, when carrying out work, it should be borne in mind that the dimensions of the beams (namely, height and width) must correspond to the length of the spans that will overlap.

In addition, when arranging such floors, the thickness of the boards that will lay the floor of the second floor and the distance between the supporting beams are taken into account.

Installation of beams for interfloor overlapping

Beams for future flooring can be installed in several ways. In the first case, the ends of the beams are cut directly into the walls, this moment is provided at the very beginning of the construction of the walls, regardless of whether you are building a brick or wooden building.

The second way to place the beams is to lay them on special brick posts. But this method is more suitable for the construction of floors between the basement and the first floor. In this case, the columns are installed quite often, for greater reliability.

The beams for the floor of the second floor are located at a distance of a meter from each other if you use 50 mm boards as flooring. If you have boards with a thickness of 40 millimeters, then the distance between the beams should be less - no more than 80 centimeters. For floorboards with a thickness of 25 millimeters, beams are usually laid in increments of fifty centimeters. Let's make a reservation right away that wooden beams for floors can only be used in buildings where spans have a length not exceeding five to six meters.

To arrange a high-quality overlap between floors, it is very important to check that the beams are installed at the same level. You can align them with building level and even board length.

The table below shows the permissible cross-sections of wooden beams for interfloor floors (for loads of 400 kilograms per square meter).

Sheathing beams and laying floors

After the beams are installed and fixed, they must be hemmed with a board, the thickness of which should be 25 millimeters. Hemming is carried out along the bottom of the beams. Next, lay the vapor barrier and insulation. Note that any material can be used for insulation, except for mineral wool. It is not very suitable for floors between floors, as it can emit harmful dust.

When all the necessary coverings are laid, you can start laying the floors. For these purposes, boards, special wooden panels and other materials are suitable. From the side of the first floor (from below), the floor beams can be covered with drywall sheets.

Recommendations for the choice of materials for wooden floors

For interfloor ceilings, beams made of dry wood are chosen. Note that the tree for such purposes should not be dried. less than a year outdoors. The optimal drying time is about three years.

Note that when calculating the number of beams for overlapping between floors in your house, you need to take into account some construction tricks. Above, in the table, you could already get acquainted with the values \u200b\u200bof the sections of beams that are suitable for floors. Now we will talk about how you can increase the withstand load.

In the construction of houses, situations are not uncommon when the use of iron concrete slabs impossible. In this case, arrange wooden floors. These structural elements of buildings are beneficial in many respects: they are durable, convenient and easy to install, provide the opportunity to perform the highest quality insulation of the building.

We choose the material for the device of interfloor ceilings

There are 3 types of floors for houses of different heights:

basement (basement, lower);
attic (upper);
interfloor.

Any of them consists of 2 structural elements: supports (beams) and sheathing (flooring). Depending on the purpose of wooden floors, they use different materials. Since they are all made of wood, installation work can be done by hand, without involving complex lifting equipment.

Wooden floors can only be built if the width of the span between the structural elements of the building is no more than 8 m.

Beam Selection Criteria

The following materials are used as supporting elements:

solid timber;
knocked down boards;
barked logs.

The standard section of the beams is 150/150 mm or 20/150 mm for timber, 140/240 or 5/20 mm for boards. You can use glued timber. In terms of bending strength, it is not inferior to solid, and often surpasses it. Any material chosen for the device of wooden floors must be well dried and free from flaws in the form of cracks, knots and wormholes.

Logs are selected by tapping on them with the butt of an ax. The tree must at the same time produce a clean and ringing sound. It is recommended to use coniferous varieties wood, as they bend much better than hardwood. The length of the beams should be such that it is possible to lay the support in the sockets intended for this purpose in the walls.

Requirements for timber floors

the design must be strong and flawlessly withstand the expected loads;
all elements of the overlap in wooden house must be designed for a service life that corresponds to the planned period of operation of the building;
interfloor ceilings should provide for the presence of a heat and sound insulation component.

Estimated load calculation

Before starting work, calculations are performed that help determine the required cross-section of the beams, the step between them, the amount of lumber. For this purpose, either special programs are used, or they are guided by standard indicators. They are:

For flights whose width does not exceed 2200 mm, take beams with a section of 75x100 mm.
For spans of 3200 mm - with a section of 100x175 mm or 125x200 mm.
For spans 500 mm wide - beams with a section of 50x225 mm.

The supports are laid in increments of at least 60 cm. If the beams are of a large section, the distance between them is increased to 1 m. The installation of the floor starts from one of the short walls of the house. Beams (logs) should be laid perpendicular to the long walls.

Technology of installation of wooden floors

To perform the work, you will need the following tools:

axe;
a circular saw;
hacksaw;
a hammer;
screwdriver;
screws and nails;
plane;
waterproofing and heat-insulating materials;
building level at least 80 cm long.

Stages of work

When walls are erected, special openings or recesses for beams are formed in their upper part. Before starting work, these nests are cleaned of dust and debris and laid in them. waterproofing material. The most commonly used ruberoid. If the walls are made of brick, the nests can be treated with bitumen or mastics based on it.
The ends of the beams are coated with bitumen.
Lay supports in pre-prepared openings.

If the structure is built of wood, the beams are cut into the upper crown. There is such a way of attaching the supporting elements to the wall, like a dovetail. It is used in houses built of logs or timber. This connection method is simple and reliable. To fix the beams, metal brackets are needed.

Wooden floors in the house are mounted according to the following rules:

the beam laid in the nest must be at least 4 cm from the walls of the recess;
beams should be located at a distance of 40-50 cm from the chimney;
each 3-4 beam is attached to the wall with anchors;
the space between the beam and the walls of the nest is filled with tow or glass wool.

The scheme of installation of interfloor ceilings provides for the installation of heat and sound insulation. Therefore, the gaps remaining after laying the beams are filled with mounting foam.

Flooring technology

Depending on the location of the observer, the wooden floors between floors can be either the floor or the ceiling of the room. There are special requirements for floor installation. Before proceeding with the installation of the flooring, each beam is hemmed on both sides with cranial bars with a section of 40x40 cm or 50x50 cm.

They will serve as a support for the subfloor. You can do the same with the flooring device that forms the ceiling. But the mounting technology of this structural element does not have special requirements to carry out such work.

The device for overlapping on wooden beams begins with fastening unplaned boards with a thickness of 15 mm or more to the bottom of the supports. They will subsequently serve as a rough ceiling. A waterproofing material is laid on top of the flooring obtained during the filing process: roofing material, a special membrane or dense polyethylene. It has a heater on it.

Mount the sheathing of the upper part of the ceiling on wooden beams. Boards are fixed with nails or screws. Knowing the sequence of work, it is easy to do it yourself. The ceiling of the house should be a sealed, durable, high-quality insulated structure. This element of the building experiences the greatest weight loads, therefore only high-quality materials are chosen for its construction.

Advantages of wooden floors

Mounting wooden elements building does not require the involvement of special construction equipment and hired labor. This compares favorably with the laying of heavy concrete slabs. Moreover, such an interfloor overlap in a wooden house in the presence of a second floor or attic is the only right decision.

An important parameter of the quality of the wooden elements of the building is the absence of cold bridges. If sheet materials are used for insulation (polystyrene, mineral wool boards), the canvases are cut strictly according to the size of the openings between the beams. If the installation of a wooden floor between floors involves the use of loose or fibrous materials, it is necessary to ensure that all cracks are filled.

An obligatory detail of any structure is the ceiling, which is erected between floors. It divides the room in height, forming floors. Depending on the structure being built and the materials used, the type of flooring is selected. This is a very important step. The cost of flooring is up to 20% of the funds used in the construction of the building, so it is very important to know how to make the floor between floors correctly.

Floor options

Overlappings are divided by design features and functional purposes. These include interfloor, basement, attic floors. They are beam, prefabricated and solid. When choosing a floor design, consider the differences in installation technologies for its different options.

Construction beam floors carried out using metal, reinforced concrete or wooden beams. They must have a large margin of safety.
The distance between the supporting beams should be 70-80 cm. The wooden supporting beam should not be more than 5 m long for floors between floors and more than 6 m between the attic and the lower room.
The span width for reinforced concrete or metal load-bearing beams can be any.
Hollow and monolithic slabs are used to create continuous floors. To prevent the plates from moving, they must be fixed with cement mortar. When installing the plates, you will have to use special lifting equipment.

Advantage and disadvantages

Each type of overlap has certain advantages and disadvantages. Wooden floors can be erected in any architectural place of complexity. The wooden beams are not too heavy and you don't need lifting equipment. For the construction of a wooden floor, you will need serious financial investments.

Note! The main disadvantage of a wooden floor is the increased fire hazard of the building.

Metal beams are durable and highly reliable. They don't burn, they don't rot. But even despite all these advantages, metal beams are used less and less. In a humid atmosphere, they are prone to corrosion, and they also do not have good heat and sound insulation.

Reinforced concrete beams are durable, do not burn, they can lay spans up to 7.5 meters, but their laying requires special lifting equipment.

Wooden floors

Beams made of coniferous wood are the main part of the wooden floor. It consists of the beams themselves, floor, rolling and insulation. If the thickness of the floor boards is not more than 30 mm, then the gap between the beams should not exceed 50 cm.

Note! Before installation, wooden beams must be treated with an antiseptic, and the ends that will be laid on the wall should be wrapped in several layers of roofing material. Leave the end of the beam open so that the tree can breathe.

Anchor bolts secure wooden beams. Attach cranial bars to their side faces. Roll up from boards or shields, which are fastened with screws to the cranial bars. According to the established reel, you make the ceiling.

Then you lay the insulation, most often used for this mineral wool, Styrofoam.

Ceilings with metal and reinforced concrete beams

You can take a rolling profile as iron beams. Between the beams lay nine-centimeter reinforced concrete slabs. Pour slag on them and fix everything with a reinforced concrete screed.

Reinforced concrete beams must be laid at a distance of 60-100 cm from each other. Between the beams, place lightweight concrete slabs. Then the overlap is sound and heat insulated.

Beamless

Such floors are a monolithic slab or panels laid closely. Beamless ceiling can be prefabricated, combined or monolithic. AT brick houses Usually precast concrete floors are used. They consist of solid and multi-hollow panels. Beamless overlap is different high strength and long term service: does not burn, does not rot, it is designed for a load of 200 kg per 1 square meter.

During installation, the plates are laid on flat surface, per layer cement mortar. The walls of the building must be at least 250 mm thick. After you finish the installation, you need to fasten the plates with reinforcing bars and fix them in the walls with anchors.

From a monolithic slab

This cover is made up of monolithic slab, which is made on site and rests on the walls. Reinforcing mesh and concrete are used for manufacturing.

Overlapping from a monolithic slab is distinguished by high surface quality, it can be made of any form of complexity.

Note! The disadvantage of manufacturing a ceiling from a monolith is the mandatory installation of formwork.

If you choose the right flooring option for your house and do all the installation and concrete works, you will get a durable and reliable overlap.

Wooden houses at one time were very popular, then with the development of modern building materials, they faded into the background a little. But today wooden buildings regain their former glory. This is due to the fact that only in a wooden house the atmosphere is filled with harmony and tranquility. Finishing in such a house can be made of any material. But this is not very advisable, since the walls made of logs look much more attractive and more natural than paint or wallpaper.

But the issue of surface finish will depend only on personal taste preferences. As for the wooden floor of the second floor, it is also made of beams. There can be no other option. On the wooden walls reinforced concrete slabs are not laid. AT ready-made the entire structure is made of natural material- tree.

Wooden interfloor ceiling of the first floor

The wooden floor between the first and second floors must meet certain established requirements:

The floor structure must be very strong and withstand the expected loads from above, it is recommended to calculate the magnitude of the loads with a margin.
Wooden floor beams must be rigid for arranging the floor on the second floor and the ceiling on the first.
The ceiling should have the same service life as the entire wooden house as a whole. Reliable overlap during the construction phase will ensure safety and prevent repairs.
For the floor, it is very important to equip additional heat and sound insulation.

Wooden beams as a floor perform all the basic functions, and they differ from reinforced concrete slabs easier installation. Human strength is enough, there is no need to use heavy machinery. Using beams, you can significantly reduce the overall load on the foundation. The advantages of wooden floors include low price. And when proper processing and the installation of such a design will last more than a dozen years.

The disadvantages of wood include such a detrimental process as decay. In addition, the disadvantages of wood products is high flammability in case of fire. In order to minimize the likelihood of such processes, it is very important to prepare the beams immediately before installation work. Best for covering conifers tree. In order to avoid deflection of the beam, it is not recommended to make a span of more than 5 m. If the span is larger, it is necessary to make additional supports in the form of columns or crossbars.

Calculation of the floor structure in a wooden house

It is from how correctly the calculation of the expected load will be carried out that you can create a high-quality robust design, which will perform its main functions and last a very long time.

Most often, the beams in the room are laid in the direction of the shortest wall. This makes it possible to make the span minimal. The step between the beams will depend primarily on the size of the section. On average, this size is 1 meter. Making the distance less is not worth it, as this will only increase the consumption of material and the complexity of the work.

It is better to give preference to beams with a large section than to make an overlap with a small step and a weak overlap.

The main dimensions of the beams for a certain span size:

2200 mm span - section 75 * 100 mm;
3200 mm span - section 100*175 mm or 125*200 mm;
500 mm span - section 150 * 225 mm.

If the overlap is made between the first floor and the attic, then the step between the material should be the same, but the cross section of the beams can be chosen much smaller. This is due to the fact that the load in the attic will be much less than on the full floor.

Tools for arranging interfloor overlapping

All work can be done independently. To do this, you need to prepare tools and materials such as:

drill;
saw;
hatchet (if necessary, large and small);
chisel;
a hammer;
nails, screws;
construction level;
fasteners.

Concerning building material, then the wood must be High Quality and well dried. Before carrying out all work, it is necessary to treat each individual element with a product that will prevent decay and make the wood less flammable.

Wood floor device

Do-it-yourself overlapping is quite simple, the main thing is to follow all the recommendations and technologies. The beams are laid on the walls with their ends. In order for them to be securely fixed, special connectors are cut out in the wall under right size sections. Laying a beam in the connector, it is covered with tow on all sides. This will prevent further formation of cold bridges. If the beam has a section size smaller than the walls, then the recess can not be made to the full depth.

The second option for attaching the ceiling to the wall is the "dovetail". In order to strengthen such a mount, fasteners in the form of a metal bracket are additionally used. Such fastening is most often used if the walls of the house are made of timber. In a wooden house, a crossbar with a beam at the same level can be fixed with a clamp.

It is worth highlighting the most common type of fastening a beam to a crossbar - this is the use of cranial bars. Such bars are attached to the crossbar, and a beam is already attached to them. It is recommended to use bars with a section of 50 * 50 mm.

For panel house beams are laid in a slightly different way. Special nests are made in the wall, into which the ends of the floor elements are laid. Optimal depth the nest is 150-200 mm, while the width must correspond to the dimensions of the section. In addition, it is necessary to leave a gap of 10 mm on each side. As in the first case, the ends of the materials must be wrapped with tow before laying in the nests.

Metal anchors can also be used to fasten the elements. With this fastening, the end of the beam will not go into the wall.

In order to make the ceiling of the first floor, it is necessary to roll forward. This stage of work can be carried out using a wide variety of materials.

In the most common version, cranial bars are nailed along the side of the beam. Such bars should have a section of 40 * 40 or 50 * 50 mm. They should not protrude below the main beam. It is on them that even boards will subsequently be attached, the thickness of which should be within 10-25 mm. In order to knock out the ceiling, you can use sheets of plywood. Using sheet material, you can get a perfect flat ceiling. The minimum thickness of plywood in this case must be at least 8 mm. It is very important to control that the edges of the sheets lie exactly in the middle of the beam.

Instead of using cranial bars, special grooves can be made in the beams. In order to use this method, the beam section must be thought out in advance.

As a flooring option, the lower part of the floor elements can remain open; for this, the cranial elements are not nailed flush, but slightly higher. Thus, the flooring is carried out between the beams.

After the roll is done, you can start laying the floor of the second floor. If instead of the second floor there is an attic, then the execution of the subfloor is sufficient. If there is a room on the second floor, then the floor must be made of quality material. wooden boards will be laid directly on the logs.

Floor insulation

In a wooden house it is very important to do good thermal insulation. This also needs to be done with interfloor overlap. Thermal insulation materials today are presented in a very wide range. It is on how correctly the material is selected and correctly laid that the thermal insulation qualities of the room will depend. This is especially important if an attic is supposed instead of a second full-fledged floor. Therefore, in order to prevent heat from leaving the room, it is necessary to lay thermal insulation between the beams.

Mineral wool would be a good option.

She has very high technical qualities, however, is not a very good soundproofing material. In addition, after a certain period of operation, its structure changes, and in environment microparticles may be released.

Particular attention should be paid to the sound insulation of the interfloor overlap.

When laying any material, it is worth controlling its location. There should be no gaps between the lags and the insulator. Sheet materials must be cut to size roll materials tucked in a bit.

If the ceiling is installed between the first floor and the attic, it is imperative to lay a vapor barrier. Deal with it polyethylene film. In order for condensate to escape from under the film faster, it is necessary to leave ventilation gaps.
