Despite the fact that wooden houses, as a rule, retain heat quite well, in conditions of an increasingly expensive electricity, special technologies are used in their construction, which allow reducing heat losses and electricity consumption to a minimum. These technologies, among other things, allow you to insulate a wooden house, making it as comfortable as possible for living, as well as prevent premature damage to wood due to dampness and condensation.

Necessary

  • Insulation;
  • steam insulation;
  • waterproofing;
  • cement;
  • antiseptics;
  • fire retardants.

Instructions

Step 1

When erecting walls, take care of in-wall insulation. It is through the walls that the greatest heat loss occurs (up to 50%). Arrange in-wall insulation already during the construction of the walls. Do this with the help of the so-called inter-crown insulation, for example, consisting of felt, linen or jute tow. For log cabins, the thickness of the insulation should be 15 mm, for log houses - 5-10 mm.

Step 2

To insulate the house from the outside, seal the walls, and then, using anchors, fix a layer of insulation on the facade, for example, polyurethane foam, expanded polystyrene, mineral wool slabs. For better fastening of the thermal insulation, make a special outer frame. The joints of the insulation should not coincide with the joints of the timber. Complete the façade with brick, decorative or building stone cladding, the bottom row of which is positioned on the ledge of the foundation. Make a gap of about 6 cm between the cladding and the insulation. Install ventilation ducts near the eaves and foundation.

Step 3

At the finishing stage, you can insulate a wooden house from the inside without affecting the floors and attic floor. You can insulate a wooden house from the inside using an additional heat-insulating layer, consisting, for example, of drywall, gypsum fiber or magnesite. Place this layer on top of the vapor barrier. A layer of plaster can also be an additional insulation. Unfortunately, with this method of insulation, the area of the room is slightly reduced.

Step 4

Up to 20% of the heat leaves the house through the roofs and windows. If you do not plan to build an attic floor, then insulate the attic floor more thoroughly. It is necessary to begin work on the insulation of the attic floor with the laying of a special vapor barrier, consisting of roofing tar, tecton, polyethylene or steklohydroisol. Lay a layer of insulation on top of the vapor barrier. Panokeralite, blast-furnace slag, fiberboard plates, expanded clay and other non-combustible materials are suitable for this layer. The thickness of the insulation layer should be equivalent to 250 mm of mineral wool. On top of the thermal insulation, arrange a sand-cement screed (30 mm) and put running boards. If you are planning an attic floor, you can get by with high-quality soundproofing.

Step 5

The insulation technology of the attic floor is similar to the insulation of the attic floor, but there are also differences. Place a vapor barrier under a false ceiling, consisting of at least two layers of 40 mm boards, and a layer of insulation on top of it. Be sure to glue the joints of the vapor barrier material with special adhesive tape. Lay the waterproofing on top, arrange the crate on top of it, and then lay the roofing material.

Step 6

The floor of a wooden house also needs to be insulated. If the ventilation of the basement is arranged correctly, you can save on waterproofing. A waterproofing layer is required if there is a risk of condensation forming in the subfloor. Place the waterproofing on the sub-floor made of board material. After that, lay an insulating layer (from 50 mm thick for summer houses to 200 mm for permanent residences) of mineral materials or extruded polystyrene foam. If mineral wool is used, add an extra vapor barrier on top of it. Seal the joints between the plates of thermal insulation material with foam sealants. Make a gap of 1-2 cm to 10-15 cm between the thermal insulation and the finished floor (for example, laminate). To protect against rodents, lay a fine-mesh metal mesh above the subfloor.
