Subtleties of thermal insulation of the ceiling of the house from the attic

The normal climate in the house depends on many factors, including the quality of the external insulation of the ceiling. Moreover, as the building is in operation, this issue has to be addressed again. If there is something wrong with the insulation in the attic, icicles on the north side of the building and the thaw patches on the roof signal this.

When the attic fully fulfills the protective function of retaining heat, in winter you don’t have to spend extra money on heating, and in the summer the house doesn’t get hot in spite of the hot weather outside the window.

The approach to ceiling insulation from the attic depends on the type of floors in the house. Overlaps are slab and beam.

Slab flooring can often be found in houses with several floors. It is quite simple to lay a heat insulator on the plates, considering that they have a flat surface.

Beam slab - this is the slab, where the main bearing elements are beams. Beam insulation is a common procedure most often used in private homes.

For the manufacture of the beams themselves usually used wood. Between these elements of the attic structure, heat insulating material is fixed. Sometimes beam ceilings are supplied with additional bars, with the help of which the heat insulator is easier to fix.

In the process, and vapor barrier is carried out. Good vapor insulators are able to pass air from the inside and do not give cold access inside.

For insulating floors can be used various materials.

Available in slabs or rolls. Distinguished by ease, durability, high thermal insulation properties, fire safety and low price. Mineral wool absorbs moisture, because of which its insulating properties can be reduced.

It is similar to mineral wool, but from the point of view of fire safety it has lower parameters. Cheaper than mineral. After working with this material, working clothes sometimes have to be thrown out,because the particles stick to the fabric - they can not be removed.

It is made from cellulose, the fibers of which lead to fluff. Due to the special additives of the flame retardant, this material is practically non-flammable. It is more expensive than similar materials.

There are many options, starting with almost free. Attic space, some residents of the seaside villages are insulated with dried seaweed, and the owners of private houses with hay, straw and dry leaves. But to use all these gifts of nature is possible only as a temporary option, since they light up instantly.

For high-quality insulation today they use claydite, which is used not only in itself, but also in a mixture with foam crumbs. Expanded clay is fireproof, but it has a large mass, and this must be taken into account when it comes to the insulation of wood flooring, which creates a serious load on the beams.

Also, slag interspersed with sawdust is used as insulation.

It is considered an effective heat insulator. It is very beneficial from a financial point of view. Well cut. Light. Resists moisture penetration.At the same time there is a high probability of its ignition. The foam does not tolerate high temperatures: at + 60 degrees it begins to lose its shape, and at +80 it begins to melt, releasing corrosive substances.

Thermal insulation with this material will last half a century, but the cost of such a solution will be more serious than using other heat insulators. At the same time, such insulation is carried out by spraying, and to create reliable thermal insulation, a thin layer of polyurethane foam is needed. It easily covers any surface. The design is obtained without seams, which ensures the reliability of heat preservation in the house.

To insulate the ceiling from the attic, you need to decide on the materials that are suitable for the particular case.

For example, in order to properly conduct work using eco-wool or polyurethane foam, you will need the help of professionals. And a person who does not possess special building skills can also insulate the ceiling with the help of expanded clay or mineral wool.

If the floor in the attic is a reinforced concrete slab, you can use clay. There should be no cracks on the surface. If they are found, they will have to be patched up. To create such insulation create a crate of timber. Expanded clay is covered with a layer of 25-30 centimeters. Level by applying rake.

For wooden floors suitable mineral wool. Working with her, you need to use overalls, goggles, respirator and gloves, since the contact of this material with the body can cause allergies.

If lumber waste is available, the space between the beams can be filled with sawdust and shavings.
