Thermal insulation of the attic with mineral wool

Wall insulation, priests, and mineral wool ceiling creates a good thermal comfort. Thermal insulation protects against the cold in winter and in summer from the heat. Used in partitions, mineral wool is well protected areas from noise

Thermal insulation of the attic with mineral wool

There is coverage of two types: dense and not dense. Loose type coating for water vapor - the roof without the filing of the boards, but only with the wind insulation (membrane) with a vapor permeability of more than 800 g / mg / day. Venting occurs through the gap between vetroizolyatsiey and roofing.

Coverage of dense type for water vapor - the roof with planks and roofing material file or vetroizolyatsionnoy film with a vapor permeability of 800 g / m '/ day. Use a rope stretched between the rafters above the insulation to avoid clogging of the vents for intake and exhaust air.

Two-layer insulation of the attic

We proceed from the fact that the standard height of the rafters often is 16 cm, and the recommended thickness of insulation for energy-efficient attic is 22-25 cm, the insulation perform in two layers.

1. Measure step rafters
Necessary to most accurately measure the distance between the rafters in the world so as to fit the insulation material to the appropriate size.

2. We select the slab of rock wool
Measures off lengths matched to the size of the clear between the rafters. Mats should be at 1,5-2 cm wider than the distance between the rafters, which will consolidate the plate "on vzhim" between the rafters, with no additional fixing.

3. Laid with the first layer of insulation between the rafters
Mineral wool is inserted in the vzhim between the rafters. Notice the tight fit insulation to the structural elements of the coating. We stretch a rope between the rafters below the filing of the boards (over insulation) to prevent clogging of the vents insulation.

4. Install steel frame
Steel frame consists of a suspension for attics with height-adjustable U-shaped profiles and C-type perpendicular to the rafters, and then bolted them to the support profiles. You can improve the thermal insulation of the attic. To this end, the remnants of mineral wool remaining after cutting boards in place straps frame before installing them. Between cooked so frame should be laid with a second layer of insulation.

5. Laid with a second layer of mineral wool under the rafters
The second layer of insulation eliminates the linear thermal bridges in the field of wooden rafters. Laid with a second layer of insulation under the rafters between the slats suspended carcass. In this layer of insulation can be placed insulated wiring.

6. Install vapor barrier, as well as walls and ceilings Attic
Vapor barrier film should be used only in wet rooms (kitchen, bathroom, bathroom). Laid with her "overlap" with the inside of the attic under the insulation, double-sided tape to fasten the bottom of the steel section. In dry areas (corridor, one bedroom) to the frame immediately fasten gypsum board or panel.
