The roof is an integral part of the whole house. It must be reliable and strong, protect the house from moisture and keep warm.
How to insulate the roof
Therefore, it is important to warm it well.
Insulated roof is the key to keeping the house warm. From the school physics course, everyone knows that the heat in the room tends to rise, t.e. on the roof. If the roof is properly and efficiently insulated, it means that the whole house will be warm. If the roof is not properly insulated or not insulated at all, then all the heat will go outside, and this leads to a low temperature in the house, as well as extra costs for raising this temperature.
Why you should insulate your roof
When building a house begins, many are limited only to wall insulation. If you only insulate the walls, you will not achieve the expected result. The foundation near the walls is deepened into the cold soil. Concrete is an excellent conductor. In summer it heats up and in winter it cools. Moisture and cold will penetrate into the room, so you should also insulate the floor and walls of the foundation.
The same goes for the roof. When the air is heated by the heating system, it begins to rise up. If it comes out through the roof, then the room will be filled with moist and cool air. To prevent heat from escaping, use insulation materials with low thermal conductivity.
Warming methods
It is desirable to insulate the roof at the construction stage. The roof of the house has a large area, so a lot of heat is lost. Before you are going to insulate the roof, you will need to decide how you will use it. If you want to use the roof as a dwelling, then you should insulate the roof on the inner slopes, if not, then you do not need to insulate the roof.
Insulation of the floor of the attic
The easiest way will be to fall asleep the attic floor with heat -insulating material. It can be a boiler slag or sawdust saw. Usually a layer of 5-10 cm is sufficient. The pluses of this method include simplicity of work and cheapness. However, there are also disadvantages – this is fire hazard.
How to insulate the roof
You can use the insulation plates. To do this, make a wooden formwork, and lay the insulation slabs between the bars. Pinch all the slots with mounting foam.
Insulation of the roof of the attic
For insulation, a heater from glass or mineral fiber is usually used. Check the beams for damage or rot. Then you will no longer have such an opportunity. Make a wooden crate on the back side. Between wooden beams, the distance should correspond to the width of the insulation. Insulation should be laid without a gap.
Errors when laying
Do not save on thermal insulation material. Roll insulation overlap. Wooden beams should not remain not covered. Increase the insulation so that the beam is inside it.
How to insulate the roof
For insulation, PPU spraying is suitable.
Having bought plates, check the integrity of the packaging. Due to the violation of the packaging, moisture could get to the insulation, so it will not be able to fully function.
When choosing a material for insulation, take into account the following.
You should choose a material that does not burn.
The volume of the design of the insulation. Some materials have a low coefficient of thermal conductivity, others high. Therefore, for the second option, the thickness of the structure should be increased.
The weight of the insulation material. It is best if your design is light. Otherwise, over the years of operation, the insulation will lead to deformation of the roof elements.
According to experts, choose fiber insulation as a heater. It has low thermal conductivity, also acts as sound insulation, easy to install and durable. The disadvantage of such a heater is that the structure should be covered with plastic wrap, as it will absorb moisture.
