Before insulation of the attic, it is necessary to check the condition of the roof and those places in which the heat insulator will be placed. Wood is treated with antiseptic solutions. Check the integrity of the waterproofing layer. If necessary, arrange a hydraulic tank. In areas of damage to waterproofing, fraud is made using a repair tape.
The entire space between the rafters is filled with a heat insulator and placed on top of the insulation. Joints are placed at right angles at the legs of the rafters so that they overlap. For insulation of the ceilings, the bulk material is used. When laying the insulation, you need to make sure that it does not dent on it. Plates are placed close to the outer walls.
One of the problem areas in the attic is the location of windows and roof. To insulate window slopes, the material is placed at an angle of 90 degrees to the window and move to the slope plane. It is also necessary to thermal insulation of the roof at the intersection with chimney and ventilation ducts. Mineral wool is taken for these areas, which does not ignite. The insulation is laid without voids and gaps.
To prevent hydration moisturizing, a vapor barrier layer is laid. The tapes are placed with a 100 mm in 100 mm. The film is fixed with tape. Then the vapor barrier is closed with facing material.
