How to insulate the attic

As you know, more than 30% of the heat of the house is lost through the roof. Therefore, the insulation of the attic should be qualitative, especially if there was a residential premises here. The poor work will lead to the fact that the cold air will penetrate through the air ducts to penetrate the house, and the resulting condensate is to accumulate between the rafters, and the wooden structures will rot and be covered with mold. The complexity of the process lies in the fact that the surface of the walls, the ceiling is uneven due to the presence of rafters, beams.

Before you start work, select the insulation material:

Extruded expanded polystyrene is safe, not toxic, not combustible. Practically does not have joints, so it is the most economical option.
Polyfoam is one of the popular materials for insulation of premises, as it is inexpensive, easy to use. However, he is not very big permeability, which means that there may be raw in the attic. In addition, as the wooden structures dry out, a gap between rafters and insulation will be formed. And these gaps will become an excellent shelter for mice.
The most versatile material can be called mineral wool: fireproof, durable, elastic, absorbs moisture, does not carry out heat, most closely adjacent to the deliberations.
Excellent sound insulation, thermal insulation properties are glass gamble. In addition, it is not expensive, not toxic and resistant to burning. The difficulty of working with a glassic lies in the fact that the laying should be carried out in protective clothing, glasses, mask, gloves. It highlights dust, particles of fibers, which, when entering the skin, cause irritation, burning, itching.

Preparing materials and tools:

waterproofing membrane;
insulation;
wooden rails;
nails, selflessness;
vaporizolyacoid material;
hammer;
stapler;
scotch;
level;
cleaning.

Along the rafter, ranging from the bottom and to the ridge of the roof, we labeled the wifone waterproofing. Fix it using a construction stapler or bilateral scotch brackets. Near the walls, we leave a small stock of the film, which after the end of all works cut off.

With the help of medium-sized nails, you feed the draft crate. The distance between the boards should be 20-30 cm. Each newly installed bar is checking the level and align on one line. To prevent the formation of fungus, rotting all the designs with a means to protect wooden products. The insulation continues after drying the surface - 1-2 days.

We lake the insulation between the rails, not leaving the gaps. So that the insulation tightly lay down to the rafters, with its string width, we make 5 cm more. For horizontal surfaces, it is better to use a solid cloth, and for beveled sections - sheets or cutting canvas. It will improve pile of cavities and help to avoid slots. If necessary, we make a second layer of insulation.

After laying the insulation, the entire space coating a vaporizolation membrane. Seams fix the mustache and fix the construction brackets.

I give the room a finished type - we are wearing plasterboard sheets, which mounted on bars or we are wearing lining.

The qualitative process of mansard insulation process significantly reduces the cost of building heating. There will be additional square meters at your disposal.
