Before starting the roof insulation, check it carefully for the presence of rotten floors, damp elements and t. D. One word roof should be in perfect condition, only in this case you can insulate it. If you close your eyes to these shortcomings, then in the future you will acquire a lot of problems and headache for yourself. You also need to check the condition of the electrical wiring in the attic, if it is there. This is another important point of preparation for insulation. If you have a house with a flat roof, then thermal insulation must pass along the roof itself, since through the ceiling itself the living room will lose half of the heat.
The floors in the attic, as a rule, are insulated from the inside. This is considered the simplest type of thermal insulation. As for the isolation of slopes, everything is much more complicated here. But this procedure is done mainly in the process of building a house. There are two options for insulation: now they often began to order kitchens to order for country houses, they are not so expensive.
1. Put thermal insulation material on the crate;
2. Either let the material between the rafters inside the attic itself.
Each option has pros and cons, but experts advise resorting to the second option, so heat lasts longer.
If you decide to triple thermal insulation in your house, then do not forget about vapor barrier. This will provide you to avoid such a problem as a greenhouse effect.
