The main functions of the insulation for the foundation – the decrease in the heat loss of the structure and the protection of the base from the destruction, freezing. However, it is possible to achieve this only by outdoor thermal insulation subject to the use of suitable materials.

Peculiarities

Wooden houses are pretty light designs compared to brick or concrete counterparts, so it can have a lightweight foundation. Depending on the features of the soil on the site, one or another type of foundation is selected. As a rule, it is a fine breeding tape, pile or pile-tape base. However, regardless of the type of system used, mandatory for all base types is the need for their insulation.

Experts are recommended to produce the heat insulation of the basement from the inside, and it is important to do it in horizontal surfaces and vertical gentlemen. Foundation insulation Outside allows you to solve a number of tasks.

Reduced heat loss at home

The lavetled foundation becomes caused to 20-25% the heat loss of the object, even if there is insulation of the walls and the floor. This is due to the formation of “cold bridges” in the foundation, through which heat goes.

Reducing the swelling of the soil in winter

The insulation of the base outside allows you to prevent significant soil freezing near the insulation. This, in turn, extends the service life of the structure, reduces the likelihood of the seasonal deformation of soil, and therefore disorders of the horizontal and the geometry of the foundation.

Reducing the number of frost cycles / defrost

Each material for the foundation has frost resistance, wood is no exception. Under frost resistance means the number of freezing / defrost cycles, which is able to withstand the foundation without losing its technical properties. It should be understood that over the winter of similar freezing and defrosting can take place over 10, What, of course, affects the durability of the foundation, and therefore the whole building. Using the insulation allows to reduce the number of freezing cycles / defrosting foundation.

Protecting foundation

Protected from the frozen and penetration of moisture foundation is characterized by strength and reliability. Blooding, wood is undergoing, starts to rot, lose strength, as well as characteristic heat and sound insulation.

Providing a favorable microclimate indoor

When insulation of the foundation outside, it is possible to maximize the dew point closer to the surface of the insulating cake, which allows to prevent the walls of the walls and insulation, to avoid increasing the humidity indoors. On the contrary, with competent heat and vaporizolation in a wooden house, the optimal humidity rate will be maintained.

Materials

Materials for the insulation of the foundation of a wooden house must comply with the following criteria:

  • Low thermal conductivity;
  • vapor permeability;
  • moisture resistance;
  • high wear resistance;
  • Easy mounting.

The most important is the characteristics of thermal conductivity, vapor permeability and moisture resistance. The smaller the material conducts heat, the more warm the house will remain. The tree is characterized by the ability to absorb excess moisture and, if necessary, give them. This is why it is so important to use the “breathable” insulation, which will be able to withdraw extra pairs of moisture, preventing them in the conversion of water directly on the surface of the walls or insulation. The insulation vapor permeability must be close to the vapor permeability of the foundation material, if it is impossible, be sure to use vaporizolation.

Among the most popular materials for insulation of wooden bases are distinguished.

Polystyrene foam

This is well known to many foam. However, today specialists recommend using its best option – extruded polystyrene foam. The latter is characterized by low thermal conductivity, it is better to resist the exposure to moisture, has a large margin of strength.

Such disadvantages of the insulation, as an environmental insecurity (in the process of use, a certain number of styrene is distinguished) and combustibility (depending on the type of product, the material refers to the class G1-G4) when installing it on the foundation becomes insignificant.

Attracts users and convenience of fixation – polystyrene foam is produced in the form of rectangular plates, has a smooth surface. For fastening, a special adhesive composition is used (it is important that it does not contain solvents), as an additional fastening – a dowel of an umbrella type.

A variety of polystyrene foam insulation is and Penoplex manufactured on the basis of extruded polystyrene foam. In terms of its operational characteristics, it is slightly larger than the latter, externally disobey.

An important point when using insulation on a polystyrene foam-based basis is their instability to the effects of UV rays, so the insulation should be closed by protective and decorative elements for the base and not stored in unpacked.

Ceramzit

Natural insulation, which is small, filled with air “pebbles”. Differs low thermal conductivity, environmental friendliness, fire safety, good record indicators, but absorbing moisture. Wet insulation, as you know, loses its technical characteristics. Avoid this high-quality waterproofing allows.

As a rule, clamzite is used in fires, as well as houses with a soil floor. In this case, the semblance of Zavaling – at an altitude of 50-60 cm from the ground there is a breakdown, the walls of which are waterproof and fall asleep by clay.

For insulation, it is better to use the material of different fractions – larger fragments will ensure the heat-insulating effect, small – fill the space between them.

Polyurene Foolder

Contemporary insulation with similar to polystyrene foam materials of thermal efficiency. Besides, It is distinguished by moisture resistance, safe, in terms of environmental friendliness, non-combustible.

Insulation polyurethane foam implies its spraying over the surface with a layer of 3-10 cm thick. Like polystyrene foam, the material is unstable to the effects of ultraviolet radiation, so it is necessary to protect it after grasping. In addition, the contact finish in this case cannot be mounted, so before spraying the composition you should take care of the crate on which the basement materials will be recorded on the principle of the ventilated facade.

Penophol

Rolled material based on foamed polyethylene with good heat insulating characteristics. Besides, One side of the product is equipped with a foil layer, the feature of which is the ability to reflect heat. In other words, the insulation acts on the principle of thermos – in the cold season, it holds heat inside the house, in summer heat – provides coolness indoors, not allowing its overheating.

In addition, the presence of foil coating improves moisture resistance and strength materials. Release form ensures ease of installation.

Features of insulation

Ideally, the insulation of the foundation should be engaged in the stage of its creation. However, in the built house, it is possible to warm up the foundation, however, the process will be more time-consuming.

First of all, it is necessary to free the foundation by calculating it to the ground. Around the foundation should turn out a trench with a width, convenient to work in it. If the design at the construction stage, you can use the special equipment to accelerate the process, if in the already built house – to dig away with your own hands.

Further, the foundation throughout the surface should be cleaned of contamination, if necessary, eliminate irregularities and cracks, dents. To obtain a smooth surface, you should use the grinding of concrete or wood. Get rid of the gaps and elevation on concrete bases allows a special solution with high clutch speed. If the usual cement-sandy solution is used instead, then you will have to wait for about 2 weeks until it grab. Leave the foundation unprotected for such a long time.

It is important that the surfaces are clean and dry (maximum humidity indicator – 4-8%). Only so you can achieve adhesion insulation.

Before getting to insulation, it is necessary to produce waterproofing. In the first stage, primer is applied. It is important to achieve the unity of the coverage – so that there are no unprotected plots of the foundation. Work more convenient to a synthetic roller with a short pile, in hard-to-reach areas – brush.

After drying, the primer is glued with rolled waterproofing. Fixation is carried out by the method of burning, there are also more expensive self-adhesive products. Glue waterproofing below up.

If you move from top to bottom, the melted bitumen layer will be dragged, so employees risk getting burns.

Next fastened insulation. If it is a plate of polystyrene foam, then they are glued (fixation is also possible on a water-soluble bitumen primer). Plates are stacked online, you need to try to avoid the formation of gaps between the elements.

The layer of insulation, which is below the soil level, just glued. After falling asleep this part of the base, the insulation will be securely pressed. Use the fasteners here is extremely undesirable, because it means a disruption of the waterproofing layer – underground water will be able to contact the foundation.

Insulation in the aboveground part can even be additionally fixed with umbrella type dowels. Under them first dries the hole of the suitable diameter, and only then screwed down or fastened.

When using fasteners, a layer of rubberoid in the underground part is usually lined up on top of it. For the basement element, waterproof membranes are usually used, which is then fastened with decorative material (on the crate).

On the installation of polystyrene foaming already mentioned above. An important point is the preliminary preparation of the crate, spraying is usually carried out by professionals.

Completely different installation is characteristic of clay. To do this, you need to roll out the trench and equip it with formwork. Next, a concrete mixture with clay is poured into the space between the latter and the foundation. After soaring this layer, it can be additionally insulated with clay, after which it is waterproofing.

If we are talking about the warming of a pile foundation with a cerazyt, then they act differently. Between the supports, testers depth 30-40 cm, to the supports themselves fasten bars with grooves. The boards are inserted into them, after which they get a kind of “pocket”, space. He is falling asleep by clay.

The process of insulation of the foundation of its backfill, the landscape of the Earth around, decorating the base or space between the pile and overlapping of the first floor.
