Insulation of a wooden house during repair or construction

Overhaul of a wooden house is a process no less responsible than its construction. Moreover, some types of work must be done again or even for the first time – if during construction they were not properly performed. For example, often the structure needs to be insulated. If a wooden house, in which they live not only in the summer, but also in the cold seasons, is additionally not insulated, the owners have to spend large amounts of heating of the home, but even this does not always help to achieve a comfortable temperature regime. Therefore, housing insulation in our country is an indispensable stage of processes such as the construction and repair of houses. We offer to get acquainted with the main modern technologies for insulation of wooden buildings.

Wall insulation: outside or inside?

Warm the walls of a wooden house can be possible outside or from the inside. Many owners and experts consider external insulation more preferable, as it increases the thermal insulation of walls without prejudice to the internal space of the house. This option is not suitable only when it is necessary to keep the exterior of the old house unchanged.

As usual, the outer walls are insulated? First, they are sheathed with a special vapor barrier film, the next step is the heat insulator. This is done like this: on the wall for fixing the film and heat insulator vertically (on the rib) stuffed Reiki. The step between the ribs should be 2 or even 3 cm less than the width of the heat insulator so that the heat -insulating material enters tightly. The construction and repair of houses involves the use of foam or mats from mineral wool as a heat insulator for external walls.

The heat insulator is laid in two layers so that the joints of the first do not coincide with the joints of the second. Then, a waterproofing film is already laid on the ribs of the rails and another frame from the rails is filled, designed to hold waterproofing and be a support for covering the facade – siding, boards, etc. D.

But sometimes the walls of a wooden house are insulated and from the inside. This is usually done when it is planned to clarify walls with a coat of drywall or other material requiring the frame. How it’s done? A heat insulator (most often mineral wool) is laid between the metal profiles of the frame for the installation of drywall, and then a vapor barrier film is attached to the frame. After that, drywall sheets are installed.

Do I need to warm the foundation?

Specialists in such an area as the construction and repair of houses recommend warming the foundation of a private house in situations where it rises significantly above the ground, that is, when there is an open section of the base of the construction between the floor and land. In this case, the foundation can be filled with clay or earth from the inside. But the thermal insulation properties of the earth layer will not be too significant. Therefore, it is better to make an additional add -on from a bronshore. Another effective way to insulate the foundation is to glue it with polyurethane foam.

How to insulate the roof?

It is best to warm the roof of a wooden house at the construction stage, as this allows you to place layers of the heat -insulating coating outside. The required tightness is achieved using a vapor barrier and waterproofing film, the procedure here coincides with the technology of wall insulation from the outside.

The difficulty of warming the roof from the inside is due to the fact that to withstand the tightness of the hydraulic – and vapor barrier in the places of adjacence to the rafters of horizontal and vertical support beams is very difficult. However, you can do this. The waterproofing film “costs” all the rafters, and it is laid so that the water drains down the film and outside the house. Vapor barrier – integral and sealed – is laid inside the attic.

Floor and ceiling insulation

For insulation of the earthen floor, a foam concrete or a layer of a granlak can be used covered in a screed. If the floor is the structure installed on the supports, it can be insulated as follows: to put the lags with a black board from below, and lay a polyurethane or a layer of mineral wool on this board. A layer of waterproofing film is placed on the heat insulator, and then the final floor is laid. According to the same principle, a heat insulator can be laid not only on floors between floors, but also on the ceiling of the house. True, in the case of the ceiling, thermal insulation materials (the same) are laid not on the lags, but between the beams overlapping
