Comfortable room in the attic under the roof insulation
Useful advice! If you decide to take the mineral wool, before laying them impossible to compress and bend. The location of the jam wool will absorb moisture.
Few choose the thermally conductive material is necessary has correctly put it. Not knowing the technology roof insulation from the inside with your own hands, you can fill in all the heat insulator attic space, and the heat in the house will not increase.
Preparatory work
The first step climb to the attic and inspect the roof from the inside. It is better to do it after a rain, when defects are particularly noticeable. But do roofing work is carried out on a warm dry day, when the dried carefully roof structure.

Warming of the roof from the inside with their own hands
Thus, the roofing material is already paved, and access to the rafters on top is closed. In this case, the work is carried out in reverse order, on the basis of false ceiling. Our task - to insulate the roof for heating the attic (attic).
Mounting waterproofing layer
First, to the sheathing installed waterproofing. Usually used for this roofing material, asphalt or tar. Cons conventional coatings is that their life - up to 20 years. Modern synthetic materials are 2-3 times longer.
The design of the roof with mineral wool insulation cake
These include Izoplast, glass, Technonikol, Linokrom, Bikrost. Some use plastic film, but it is an economy version. Waterproofing overlapped, with an overlap at the edges of 20-25 cm. It is attached to the crate staple gun or cramps.
Filing insulation
Next is laying insulation layer. Slabs of insulation is best to mount vraspor with rafters that they are retained in a natural way. For this purpose, the sheets must be slightly wider than the distance between the rafters. If the gap is not, then the heat loss through the roof reduced to a minimum.
The gaps between the insulation and rafters should be minimal
Achieving integrity in the process of warming the inside of the roof with his hands, the plate can be bonded to each other. For reliability arrange extra crate. Not only does it hold the plate, but also serve as a basis for the ventilation duct.
Important! In qualitatively arranged roof has two air gap. Origin - between slate roofing material and the second - between the roofing material and insulation. And it's not just a free space - air must circulate in it.
Work on the roof insulation should be carried out in overalls, goggles and a respirator
Laying vapor barrier
Whatever water repellency may be painted in the instructions to the insulation, vapor barrier of the roof is necessary. The steam which is produced in excess in our life support system rises. In summer, it evaporates and condenses inside the roof in winter. Moisture leads gradually deteriorated and the insulation, and the roof structure itself.

It is better to use a professional diffuse film, which passes the steam to one side. These include Izospan, Yutafol, Pentaizol. This double-sided "breathable" materials to ensure an optimal micro-environment in the room.
Steam insulation film protects the insulation from the condensate accumulation
The film is stitched to the rafters, the smooth side of a heater. Rough surfaces should be directed towards the room. It effectively keeps condensate droplets that evaporate slowly. In order not to hinder the process, between the ceiling and the film is left in the space of 4-5 cm. The strips are placed with overlap the vapor barrier of 12-15 cm, fixing them horizontally. For the binder used staple gun or galvanized nails.
I want more to warn about the dangers of home handyman excessive savings. Through Roof insulation from the inside with your own hands, some sutured foam roofing, paving as polyethylene waterproofing. Vapor barrier with a generally neglected, either stacked polyethylene film laminated spiked roller.
Campfire (waste from the processing of flax) - cheap and totally natural insulation
Such a "vapor barrier" layer only has the effect of greenhouses. The house becomes damp, condensation from the rafters begin to rot, there is a musty smell. The constant humidity conditions the life of the foam is sharply reduced. Therefore, it is not recommended to save on heat-insulating materials.
Insulation of floors with unheated attic
If the attic is designed only for ventilation, then insulated attic floor. It uses a filling of slag, expanded clay, loose ecowool. If the attic floor is a concrete screed, mounting plates before it is recommended to set the joists, between which insulation is to be laid.
Expanded clay can be used as insulation for the roof and floor
Useful advice! lag thickness should be slightly greater than the thickness of insulation that between them waterproofing layer remained ventilation gap.
The technology works with foam insulation
Popular type of roof insulation from the inside with their hands was foaming penoizol. To do this, the contact surface is moistened, which would increase the adhesion of materials. Then the liquid is sprayed foam thin layer. Once Penoizol increase in volume and will seize, is applied another layer, if necessary. The foam fills all defects, cracks and holes, insulate and seal the overlap.
Slice of cake with roofing foam insulation
Frozen insulation cover with roofing felt and sew the top with plywood or plasterboard. This will protect it from the sun's rays and pollution. Penoizol has a long service life, does not crumble and does not shrink.
Technology laying roofing pie is the same - foam insulation should be placed between the layers of waterproofing and vapor barrier. Insulation film in this case fixed to the carrier elements overlap, and then closes the finishing ceiling. Between the film and the ceiling must be a ventilation gap to where the water was evaporated.
Glass wool has low thermal conductivity and does not transmit pairs
Finally. To protect the house from the cold, there are many ways and one of them - the insulation of the roof from the inside by hand. If desired, any homeowner can perform such work, if you want to enhance the thermal barrier of his house.
