In order to save heat in a wooden house, you need to insulate the foundation. Today, several such methods are known that have an excellent level of efficiency, and they need financial costs, the value of which can be different.
Which of the ways of insulation to choose depending on the capabilities of the owner of the house and whether the house is used year -round, whether significant costs in the heating season, that is, whether it is worth acquiring thermal insulation. If they live seasonally in the room, then they use effective, but at the same time cheap ways.
Insulation of a wooden house with stoves of foam
How to insulate the foundation
If the material used (insulation) is placed on an increase in efficiency, then the list will look as follows:
expanded clay;
foam (slabs), penocerol, foam;
Polyurethane foam.
Consider each method separately.
In order to warm the house with expanded clay, it is necessary to create a pillow that will absorb and remove moisture, as well as the surface will remain airspace. With this method, the base of the house will not freeze.
Consider how to insulate the foundation of a wooden house outside, using expanded clay:
The foundation is dug to the full depth, remove dirt, dust and soil residues. If necessary, using a concrete solution, the cracks are covered, and with destruction, the surface is aligned. Waterproofing work is carried out as additional protection against moisture. For this, the base from the outside is coated or glued the base with a special material;
The ditch is covered with expanded clay, the concrete blind area is installed on top, it protects the material from the ingress of liquid and its siltation. The base is insulated by applying slab materials or simply whispering.
If they want to insulate the semi -basement, then expanded clay must be filled during flooring or replacing the black regulatory. To do this, at first they make a pillow of sand and pebbles, there is a film waterproofing on top (it warns the capillary fluid leaks from the soil), then expanded clay, and its level should coincide with the height of the Chernopol. To save material, filling is performed only from the inside, more precisely, along the inner contour of the house. To do this, make a wood formwork, firmly fix it with struts, and expanded expanded clay between the base of the house and the formwork.
How to insulate the basis of the house with polystyrene or polystyrene and polyurethane foam
In fact, polystyrene is one of the modifications of the foam, which shows resistance to moisture, in addition, it is strong. The manufacturer produces this insulation in the form of plates with different thicknesses, dimensions and density. This is quite convenient for the consumer, since it is easy to choose the material with the necessary thermal insulation characteristics.
Ceramzit – insulation
Such plates have one drawback – this is their combustibility, so they are not always suitable for wood structures. But if it is necessary to insulate the underground part of the base, then they should be consumed. And for the insulation of the basement, polystyrene with anti -piren supplement is used.
Consider the technology of insulation:
The foundation is carefully prepared, for this they free it from dust, bitumen, oil, soil, since polystyrene can lose thermal insulation properties, and all the work will go down the drain. If necessary, the foundation is repaired: it is covered with cement of cracks, the destroyed surface is aligned, and coating waterproofing is covered on top;
glue polystyrene slabs with special glue, it is applied along the edge of the material and several more points on its surface. After 30 – 60 seconds, they are pressed to the foundation. When gluing the second plate, the grooves are combined. In order for the dry glue, it is necessary for 48 hours, after the backfill is made;
The base is insulated in the same way, but there are some nuances. A 15 – 20 cm layer of cotton (basalt) is applied to the wooden structure, and the insulation is laid on top. After the glue grabs, the tiles are additionally fixed with dowel-clavics. In this case, the holes are drilled to concrete and nailed the dowel so that the hats fit tightly to the plate.
The use of polyurethane foam is considered the latest technology, which has become popular among dacha owners. Consider, the foundation of a wooden house with this material. These works are considered highly standing, since it is necessary to apply special spraying equipment, and for these works it is necessary to invite specialists. The foundation is cleaned from dust and repaired. This type of insulation is carried out both outside and from the inside.
Optimal time for work
It is best to conduct insulation at the beginning of construction, when the walls are not exhibited, and the black floor is not covered. But this problem most often occurs during the operation of the building.
The first signals are considered the appearance of mold and dampness in the basement. But even in this case it is not too late to insulate the foundation.
After the structure is built, then there is a lot of space inside the base box. If they plan to arrange a basement there, then the voids are covered with soil or expanded clay. Their height should coincide with the floor level.
Insulation of the foundation of a wooden house with polyurethane foam
The first method is cheaper, since there is a lot of land left when digging the foundation. But this method has a minus, this is low thermal insulation. Therefore, it is more profitable to sprinkle expanded clay, which fill the box by 40 cm height. But then there will be no basement in the house, but it will become possible to place communication and its ants underground underground.
Conclusion
In order to insulate the foundation of a wooden house yourself, you need to know the nuances of this case and understand them. If you have never done this, it is better to seek help from specialists who will help you choose the material, and everything you need will do not only quickly, but also of high quality.
And most importantly, in the future, problems with thermal insulation of the house will not appear, and in the winter, the structure will be warm, comfortable and comfortable.
