Without a heat insulated roof it is impossible to imagine a comfortable living in cold climates. So warming the roof becomes the key to the reliability of the whole house, its ability to protect residents from low temperatures and unpleasant drafts. And in the presence of an attic floor, it becomes an indispensable condition for the possibility of operating premises.

Preparatory stage
If it is decided to carry out the roof insulation with your own hands, the following tools and materials should be prepared:
- Insulation Isover Profi in rolls;
- construction stapler;
- vapor barrier film;
- tape measure;
- knife.
Material for insulation Isover is recommended to be purchased in rolls. The entire roll can be easily cut according to the pitch of the rafters. Further, it easily fits into the space between the rafters and, due to its elasticity, does not fall out from there. Therefore, such a roll can be easily unwound and installed both in inclined planes and in vertical planes. If necessary, it can be cut into fragments of any size.
The material in the rolls can be of different thicknesses: 50, 100, 150 mm. The choice of a particular option depends on the climatic conditions of the region. If the roof insulation of a house in your region requires a thicker layer of insulation than what is on sale, you can overlay the second layer on top of one layer. Additional fasteners are not required. The layers of Izover will be kept at the expense of their elasticity. Another indicator of the thickness of the material is the height of the rafters.
The main stages of roof insulation
The technology of roof insulation includes several stages. First, they carry out external works. Before fixing the roofing material, a vapor barrier membrane with windproof properties is applied. This layer protects the structure from moisture. The membrane is lapped, joints are glued with building tape.
When the external insulation is finished, proceed with the installation of thermal insulation from the inside of the frame. For this purpose, the distance between the rafters is measured.
If it is equal to 60 cm, then the roll can be simply cut in half. The photo or video clearly shows how to do it. Half of the roll will occupy one strip of the roof slope. In this way, the roof is insulated.
If the step is rafters non-standard, roll Isover Profi unwind and cut the plates of the desired size, leaving allowances about 1 cm. If it happened that the distance between the rafters is not the same, then do not be scared. It's just necessary to cut off a fragment of heat-insulating material of such size that it was not less than the widest distance between the rafters. In those areas where the width of the isover will exceed the distance between the rafters, it can be squeezed.
So that the insulation of the roof of the mined Ivora will not cause difficulties. The elasticity of the material will allow it to stand tightly in any structure. Isover has other advantages:
- good thermal insulation properties;
- dense space filling;
- durability( 50 years and more).
The next step, which includes the roof insulation from the inside with your own hands, is the installation of a vapor barrier membrane.
It is attached to the rafters using a stapler. The overlap is mandatory.
Joints of individual fragments of the membrane are glued with building tape or mounting tape.
On top of this, it is desirable to install an additional monitor. It will be required to create the necessary clearance between the vapor-barrier membrane and the inner lining.
After the completion of these works, the cladding is done with plasterboard boards or lining.
