How to insulate an attic
Attic — the invention of the French architect Francois Mansart. It was he who first thought it such a good place like the attic at home, to go to waste, so he built the "broken" roof, which gave the opportunity to organize another extra room. This romantic room is well, but has one drawback — it's cold. So you didn't freeze in the winter, the Soviets will tell how to insulate an attic.
After the construction of the attic the first Frenchman such economical and low-cost rooms directly under the roof has gained its popularity among the poor and artists. On the one hand, romantic people love to see the city at night from the roof of the house, and on the other hand, did not need a lot of money for renting such a room. In the modern world of the attic does not lose its popularity. Many designers of private homes add to the plan of construction is economical and very profitable room.
But the catch is that in the attic was very cold. What, after the walls and roof of the attic in contact with the cold air outside. It turns out that the attic insulation is a necessity. And in the house the heat will be retained much better. Let's see how to insulate the attic the best.
The attic insulation from the inside is required to very carefully. Because the simple insulation of walls will not be enough. For better heat conservation will need to take care about the insulation of the floor and roof. Consider also the creation of a waterproofing layer to your attic long served you.
Let's see how to insulate the attic. This is best done with the help of special materials. For insulation use mineral wool boards based on glass or basalt fibers. This insulation proved best. In addition, you can easily put the plate in several layers. And the greater the thermal conductivity coefficient of the insulation, the less layers of mineral wool you'll need.
The attic insulation foam is undesirable. To make this efficiently is almost impossible, because do not forget that the foam has a lot of minuses. Even with high-quality work is always a great probability that there will be many bridges. And the foam insulation is so popular only because this material is very cheap. But the sense of insulation foam will not be enough.
Please note that a special approach requires the roof insulation. Because the roof has two functions — it conserve heat and protect the interior from moisture. Therefore, you need to clearly know how to insulate the roof of the attic. This process should take place in two stages. It is best conducted during the construction of the attic. For a start on the sheathing of the roof must put a waterproofing material which will later be hidden under the roof. Under the waterproofing layer will be a layer of insulation. As a waterproofing material you can use roofing felt or sarking. But those cheap materials have the disadvantage — they do not allow steam that will emerge from the layer of insulation. So think about how to purchase the more expensive material for waterproofing. It can be diffuse membrane, anti-condensate film.
Before you insulate the attic be sure to pay attention to the internal structure. It often happens that they have to strengthen and even increase their number.
Also in the attic, you must insulate the floor. After all the warm air from the lower areas up to and through the septum. Insulation of the floor of the attic will give you the opportunity not only to retain the heat on the lower floors, but will make room under the roof warmer. So, for the floor insulation of the attic, use a layer of glass wool or mineral wool with a thickness of 10-15 cm Insulation be sure to put on a layer of vapor barrier. Only after that glass can fill the space between the beams so as not to leave any gaps.
