Warming of the wooden house foundation

Warming foundation of wooden houses - one of the most effective measures for building insulation, which allows to save up to 25% heat from the outgoing house.There are several ways of warming of the foundations of a wooden house, they have varying degrees of effectiveness and require different financial costs.The choice of insulation depends on the possibility and expediency of investments: if the house is used for living, and heating costs are significant, it makes sense to invest in modern technology teplozolyatsionnye.For the garden, heated from time to time, you can use cheaper but less effective methods.

basement insulation methods

Ascending effective way of warming of the wooden house foundation may be arranged:

• Insulation of expanded clay;
• Warming plates Styrofoam, polystyrene, Penoplex.
• Thermal insulation using polyurethane foam spraying.

With increasing efficiency and increases cost of works and materials.Therefore, before deciding on a particular type of insulation you need to calculate the cost of heating homes and choose the best option.

1. most common insulation keramzit outside.To do this, dig up the foundation for the rest of his depth, clean it from the residues of soil and dust, if necessary repaired - sealed cracks with cement mortar, level the surface in areas of destruction.Additional protection against moisture is a basement waterproofing on the outside of coating or back-lining method.
2. resulting trench is filled expanded clay to the ground level, on top of it carried out a concrete blind area, protects the concrete block by siltation and moisture.Ground part of the foundation insulated by means of plate materials or plastering.

3. Insulation of expanded clay basement space is sufficiently effective measure for insulating floors.Expanded clay fall asleep on stage flooring or replacement of subfloors, by first performing a sandy base, it is laid a layer of waterproofing membrane, warning rising moisture from the ground and poured concrete block on top of the film to the level of sub-floor.In order to save can be made of expanded clay backfill is not the whole area of ​​the house, but only on the inner perimeter of the foundation.To do this, perform the wooden formwork permanently fixed braces, concrete block and poured between formwork and foundation.

Insulation of basement with polystyrene foam or polystyrene

- modification of the foam, durable and resistant to wetting.Plates are available in different thickness and density, which is useful in the selection of heat-insulating characteristics.The disadvantage of polystyrene plates for thermal insulation of wooden structures is their flammability, but for insulation of underground part of the foundation is not a nedostatkom.Dlya plinth insulation should be selected polystyrene with flame retardant additives.

technology insulation:

1. Careful preparation of the foundation: liberation from soil residues, dust, oil and bitumen traces - polystyrene in the neighborhood with them loses insulating properties.The surface of the foundation, if necessary, repaired, apply several layers of surface waterproofing.
2. polystyrene plates bonded on polystyrene adhesive applied along the edges of the plate and at several points across its surface.Plate kept on air for about 30-60 seconds, then pressed firmly to the substrate.The next plate paste, combining the mounting slots on the adhesive plitah.Vysyhanie lasts up to two days, then it is possible to produce backfill the underground part of the foundation.

3. Warming cap produced in the same way, but with some nuances.It is necessary to separate the layer of polystyrene on a non-combustible timber structures layer of insulation, for example, basalt wool.Enough bandwidth 15-20 cm, laid on top of the cap.After fastening insulation boards and setting the adhesive must also be fixed with special dowels, nails, holes have been drilled through the plates to the concrete and dowel scoring to full fit the cap to the plate.

Thermal insulation with polyurethane foam foundation

This technology is new, and at the same time very popular with owners of wooden houses.The high cost of installation due to the use of a special spray and specialized labor force, but it is more than compensated by the high insulating properties of polyurethane foam insulation.For applying foam necessary to call a specialist.Special training base is not required - enough to clear it from dust and repair all damaged areas.Thermal insulation with polyurethane foam can be carried out both on the outside of the foundation, as well as from the inside.
