Warming of the floor in a frame house on stilts: a step-by-step instruction, features and recommendations

Warming of the floor in a frame house on piles should be carried out, taking into account the structural features of such housing. Only in this case you will not face the problem of lack of comfort inside the premises. When the house is installed on supporting pile elements, it usually has a basement or a basement. This can be considered a virtue that slowly flows into a disadvantage, consisting in purging the bottom of the house from all sides.

Features of insulation

Such buildings are erected on marshy soils, so the space beneath them is characterized by a high level of humidity. In order for the house not to be exposed to the negative effects of natural factors, its floor covering needs to be arranged in several layers.

Thermal insulation cake

Warming of the floor in the frame house assumes the presence of a bearing skeleton, which is combined with the rough floor. Next comes the wind protection, which differs vapor permeability. It is required to protect the applied insulation material from weathering. The next layer is laid heat insulator, closed by moisture and vapor barrier layers. The final floor will be the finishing floor, which is covered with boards.

How to exclude errors

Choosing a warming material for such a "pie", it is necessary to be guided by the fact that it must have high quality. It is recommended to use good steam, as well as waterproofing products, which will reliably protect the premises from humidity. If the floor insulation in a frame house installed on stilts is not met by all the rules, then you can face an increase in heating costs, the presence of condensate over the underground and the appearance of fungus and mold.

Recommendations for material selection

Thermal insulation of pile structures is possible using several technologies, as the main requirement in this issue is the need to use materials that could be used in wet conditions. Warming the floor in a frame house with foam plastic is one of the best and most rational approaches. But at low temperature and high humidity this material is destroyed by separate elements. If you want to use this insulation, you should take care that it is reliably protected from moisture.

Mineral wool is also quite common for solving the described problem. It is inert to biological influences, has high heat-shielding characteristics and is not afraid of fire. But with the penetration of water inside the protective properties of the insulation are lost. With appropriate measures, you can use any type of mineral wool, among them:

• Stone;
• Glass;
• Slagy.

This heat insulator is realized in rolls and plates, but experts recommend using the latter option, since it has a more impressive density in comparison with the roll analogue.

Warming of the floor with foam in the frame house is also quite often. This material is expanded polystyrene, manufactured by extrusion technology. It has an insignificant index of moisture absorption and has a high strength. These features give the material many advantages over cheap analogs. If you make a comparison with polystyrene foam, then foam foam will be more reliable.

Alternative solutions

Warming the floor of the frame house with expanded clay is also quite common. Use this material is simple, but there is no need to resort to outside help. Keramzit is distinguished by fire safety and low cost. But when compared with the materials mentioned above, the heat-protective properties of claydite are inferior.

In the role of hydro and windproof materials for floors on a pile foundation, vapor-permeable moisture-barrier insulation membranes should be used, which are easy to install. However, you should be prepared that the cost of such substrates is quite high. As a vapor barrier can be used a simple polyethylene film, which is laid directly on the layer of insulation.

Features of the insulation of the floor with expanded clay

The first, with thermal insulation of the floor with expanded clay, is a layer of waterproofing. In this case, it is especially relevant, because the heater absorbs moisture well, which can cause unpleasant consequences. To achieve uniformity, before filling with expanded clay it is necessary to set guide beacons that will determine the level of the future floor.

For reliable fixing of the heater, a layer of screed is used, as well as an upper waterproofing. Before applying the final top layer of the screed, the intermediate fixing layer should be poured. For this, the cement is mixed with water to obtain a uniform suspension. It should be poured a layer of expanded clay. After the drying of this layer you will be able to get a monolithic expanded clay floor, which will not be afraid of moisture and high loads. Such a design can withstand even a small earthquake. The final layer will be a screed, with which you can completely level the floor.

Step-by-Step Instruction for Floor Insulation

At the first stage the rough floor is arranged, for this purpose a wooden bar is attached to the logs, which is also called the cranium. It will serve as a support for the boards of the finishing deck. Used wooden elements must be treated with an antiseptic, in the next stage you can start installing boards.

If you decide to use expanded polystyrene or polystyrene, then it is recommended to lay the grid in place of the rough floor. It is fixed to the lags so that it is able to withstand the weight of the heat insulator used. Overloading piles overweight is not recommended. After completion of the arrangement of the rough floor, a vapor barrier is laid on its surface. All the moisture from the outside will remain outside, but it will not affect the insulating layer. This area can be vapor-insulated with a polyethylene film, which is often replaced with a roofing material.

Warming of the floor in the frame house at the next stage involves the installation of thermal insulation. On top of it should be a layer of vapor barrier, which excludes the penetration of condensate and internal moisture into the "pie". When laying the vapor barrier, you should get rid of the gaps that can remain between the webs of materials. Otherwise, cold bridges may arise , which are dangerous for thermal insulation, because they will soon destroy the structure of the material.

At the next stage, you can proceed to laying the finishing floor, using wood chipboards, floorboards, plywood sheets or other products. Warming of the floor in the frame house should be accompanied by the protection of the piles with a stationary base. In this case, snow will not fall under it. But if you do not intend to build a warm space or you do not have the opportunity to do this, then the supporting elements should be covered with a decorative base, which is fast and inexpensive.

Warming of the floor through the basement

When the floor is insulated in the frame house, you can close the base with your own hands, using one of the existing methods. What is used for brick or rubble masonry, skeleton imitation of the socle, the last of which allows to equip the ventilated facade analog. If you decide to use the masonry, then the tube must be built using half the bricks. The first row should be laid on a pre-arranged cushion of sand, which is well trampled.

The vial must be waterproofed using a roofing material. Correct warming the floor of the frame house necessarily involves the thermal insulation of the base. For this, its imitation can be used. This technique allows you to complete the work in the shortest time, saving money. The frame is made by installing a crate of wooden beams or a galvanized profile. Install them directly on the piles. This construction is covered with a roofing material at the next stage, PVC sheets are installed from above, which imitate stone or brick. Polyvinyl chloride products are reinforced with nails or universal screws. The first option is suitable for a wooden crate, while the second one is suitable for a metal profile.

Double insulation

Double insulation of the floor frame house involves the use of double floor technology. From the title it is clear that the flooring of the boards will have to be done twice, but the boards will be different. The rough floor will be equipped with uncut boards that fit well together. Above is laid a layer of roofing material, which will protect the wooden floor.

The next layer will be sand, the height of which should be a limit of 3 to 5 cm. Next, sand is covered with a plastic film, reinforced with nails or a construction stapler. The next layer will be heat insulation, which is pre-cut into pieces. Over should lay the chipboard, which will be laid flat.

Features of cross thermal insulation

Cross-warming the floor in the frame house is also used quite often. When the plinth is equipped with beams with the following dimensions: 200 x 500 mm, the thickness of the insulation must be 200 mm. The top layer of thermal insulation should be located perpendicular to the lower layers, which gives the name of the technology.

Conclusion

Warming of the floor in the house with a foundation on the piles can be carried out in a thorough manner, but if you want to experiment, then the insulation can be carried out even with the help of carpet. This method is great for those owners who have not yet decided to open the floor.

To do this, you should use a material that is similar in characteristics to conventional carpets. Lay the carpet along the entire floor area of the room, touching the perimeter. This approach will close the cracks on the concrete and wooden floor, through which cold air penetrates from the basement.
