Warming walls in the house or in the apartment will allow for a longer time to keep the heat in the room. Particularly relevant is the task for residents of corner apartments and private houses. Work on the insulation of the walls is made for a long period, therefore, a heater for the walls of the house from the inside, must have a high quality of thermal insulation to preserve it for many years.
Necessary qualities of a heater
The modern market is saturated with a very large number of insulating materials, each of which has certain advantages, but along with them, there are some negative qualities of heaters.
To the positive qualities of insulating materials we can relate in the first place - fire safety, the composition of the insulation must not have combustible properties, the material should be harmless to health, do not release toxic substances during operation. It is very important that the insulation has a low thermal conductivity, this will not let heat out of the room, the lower this figure, the thinner the used sheet of material, and this, in turn, will reduce the thickness of the accreted wall.
Moisture resistance is one of the most important requirements for a heater, this will allow it to maintain its stable shape and provide a longer service life.
Types of insulation
There are several common types of insulation for walls from the inside of the room. Let's consider in detail all their advantages and possible disadvantages.
Today, the best insulation for walls from the inside, many experts call expanded polystyrene , it has been used with great success in European countries, and recently it has found its application in our country. The presence of positive qualities can not be overestimated. Expanded polystyrene is very light, it is easy to handle, it can easily be cut with a knife, all this makes it easy to install, to attach it to the wall use glue or dowels. At the same time, it easily resists a large load. It has low vapor permeability, does not absorb moisture. Bad thermal conductivity will allow a long time to keep heat in the home.
Very popular is a roll insulation for walls from the inside - mineral wool , it is laid inside a hollow gypsum board structure. Such insulation is inexpensive, but the result is not of high quality. Mineral cotton wool absorbs moisture, afterwards, it can lead to both smudges on the wall and the appearance of fungus.
Quickly and qualitatively it will allow to warm the walls of polyurethane foam . This material is easy to use, do not waste time on its installation, it is simply sprayed onto the wall surface, which must be insulated. The two components that make up the foam polyurethane foam, falling simultaneously on the wall, and connecting. Composition instantly freezes. It can be applied to any surface, including the ceiling, which is very convenient, if necessary, its insulation.
A rather common material for insulation is foam , but it has a number of significant drawbacks. Polyfoam requires additional protection from mechanical damage, as, it has low strength. Also, it is a highly combustible material that releases high-toxic substances during a fire. When the foam is insulated , the usable area of the room is lost.
A relatively new material for insulation of walls - foam glass becomes popular. Unlike foam, foam glass does not absorb moisture, is not prone to fire, it is well plastered, it is easily fastened, with the help of liquid nails or glue.
