Roof insulation with own hands

Almost every private house needs high-quality insulation. First of all, we are talking about the insulation of the roof, through which very often warm air flows and leave the dwelling. It is worthwhile to understand that such a process should be carried out regardless of the shape of the roof.

Carrying out of qualitative warming will allow not only to enjoy stably high air temperature indoors, and even in the coolest seasons, but also to save money, which is usually on a large scale spent on various heaters and other sources of heating. In the end, you can confine yourself to the simplest means of heating, and the thermal insulation will keep the necessary amount of warm air in the house.

Features of the use of thermal insulation

Before all work related to the insulation of housing, you need to study all issues related to the effectiveness of varioustypes of insulation, the scale of house insulation, and also to analyze financial issues.

Applying the wrong kind of insulation can completely not notice the effect of the created thermal insulation. It is also possible to spend too much money on these or other materials, and it turns out that the cheapest level of thermal insulation can provide approximately the same level of insulation.

The process of preparing the roof for insulation

Immediately it is necessary to say that the insulation of the roof is internal and external. To the outer part of the roof is the roof, and to the inner - the rafter frame, as well as slabs. Before starting work on laying thermal insulation, make sure that the roof is in a normal state. Otherwise, the large weight of heaters can simply destroy the construction, while you have to spend a lot of money for restoration.

Also worth assessing the situation with humidity. If the damp is present on the roof, it can significantly damage the heater. In such an environment, insulation materials are rapidly losing their original properties, or efficiency is simply lost. The presence of moisture does not mean that the insulation can be thrown into the garbage can after a few days after its installation on the roof.

It is worth making sure that the distance between the rafters is ideal for placing insulation materials. The insulation should ideally ideally enter the necessary space, which will ensure high efficiency of the material use. The presence of cracks is a rapid loss of heat, which will only increase with time. Once again it must be recalled that the thermal insulation must always remain in a dry state. If the roof is leaking, heat insulation should immediately be protected from water ingress.

Insulation materials

The following materials are most often used for roof insulation:

  • glass wool;
  • basalt slabs;
  • polyurethane foam;
  • mineral wool;
  • polystyrene foam.

Among these materials the most versatile is glass fiber( glass wool), which not only perfectly preserves heat in the dwelling, but also provides high-quality sound insulation.

Also experts emphasize the fact that fiberglass has a unique texture that allows the material to be used for decades without losing its initial properties. Moreover, unlike the use of other materials, the insulation of the roof with fiberglass will significantly save money. If necessary, individual parts of insulation can be replaced quickly and cheaply.

If there is a need to use environmentally friendly as well as fireproof material, it is worthwhile to look at the use of expanded clay. Despite its many positive sides, the cost of the material is quite high. However, the belief that due to the ignition of the heater will not happen a fire - it's worth a lot.

Roof Insulation Process

If the roof is a non-residential attic, then the insulation should not be placed between roof rafters, but directly on the overlap between the lags. Then the material is located around the perimeter of the roof. It is worth making sure that all elements of insulation are installed qualitatively and without the slightest cracks.

After that you can begin the process of laying the OSB material on the floor surface, which will become an excellent basis for the floor.

In the event that we are dealing with a flat roof of a dwelling, the process of warming begins with the creation of a cement screed. Next, most often, there is stacking of polyphenylene polystyrene, the density of which should be at a sufficiently high level. Otherwise, the effectiveness of insulation is not enough for a large house.

After that, it will be necessary to place on the surface a fiberglass, which has filtration properties. At the very end on the surface there is gravel and paving slab( paving stones).

Installation of insulation on a pitched roof

It's probably the pitched roof is the most complex object for the location of thermal insulation.

In this process, you will need to create a waterproofing layer that will get rid of moisture. It is important to note that the waterproofing is located on top of the crate, and the material is fixed by means of bars. Further, between the rafters is laid insulation material. It is necessary to pay special attention to the fact that there are no gaps between the insulation. In those rare cases, when the insulation is placed in several layers, it is necessary to make the new layer overlap the seams of the previous one. This greatly increases the efficiency of insulation.

A membrane film is placed on top of the thermal insulation, which will protect the material from condensation. Such layers are attached to the crate with a construction stapler. It is necessary to make sure that all the materials that are used to create warming do not sag. Otherwise, the created design can be damaged or gradually lose its effectiveness.

In some cases, the vapor barrier can be attached to the attic with the help of an adhesive tape, but this happens only in situations where it is really necessary.
