Roof insulation

Before insulation of the roof and attic rooms, all supporting roof structures should be inspected for rotten ceilings, moss and moldy, damp elements. If they are found, they must be eliminated, replacement of unusable beams. Without doing this, you add yourself a headache in the future. After paving the insulation on an unsuitable design, you will have to finally disassemble everything anew and make major repairs.

Another preparatory point for thermal insulation will be checking the wiring in the attic, if any.

If defects are found, they must be eliminated.
Usually in homes where the attic is not residential, the roof carries only a protective property from weather conditions. Such attics do not require compliance with a positive temperature in the winter, and warm them only on the floor. Which in turn is also the ceiling of the residential floor below. For insulation using insulating material, for example, mineral wool or polystyrene foam.

If the attic is used as a dwelling, whether it is an attic, a studio or a warehouse of things, then it is necessary to warm it around the perimeter.

In houses with flat roofs without an attic, heat insulation necessarily passes on the roof itself, because it is through the ceiling that the room loses half of its heat.

Attic floors are always insulated from the inside. This is the easiest type of insulation. Isolating stingrays is much more difficult. This is done mainly during the construction of the house itself. There are two ways: either to put heat-insulating material on the crate, or to put it between the rafters inside the attic. The first option will not work if insulation of the attic is required in an already residential building. But this method is more reliable than insulation from the inside. But internal insulation is more functional. The attic will be better to warm up and keep warm for yourself longer.

You need to know that outdoor insulation is a matter of specialist. Only a good master can do this correctly, squeezing the maximum of all the properties of thermal insulation. Not even a professional can cope with internal warming, for a beginner is also able to glue insulating material on the ceiling.

Laying mineral wool as a heater does not require special skills. Mineral wool plates are simple and easy to use, dock without any problems. This material is fireproof, withstands temperatures of a thousand degrees Celsius. Its service life is fifty years.

The minimum thickness of any insulating material is 2.5 cm. For thorough and complete warming it is better to use a thickness of 10 cm.

Arranging insulation in the house, we can not forget about the vapor barrier. Otherwise you risk getting a greenhouse effect in the attic. Vapor barrier provide: the gap between the roof and a layer of insulation; the presence of a special layer of vapor barrier (foil or plastic film). Some materials already have a special foil film to provide vapor barrier for the roof.
