First of all, the roof is protected from bad weather: rain and searing sun.This may explain the holistic approach to its construction and covering.Thermal insulation of the roof - an important aspect of the changes at home.As you know, warm air rises because it is lighter than cold air.That is, even if the walls are covered with a thick layer of insulation, air will cool rapidly under the thin roof.During the summer there will be a boomerang effect: glowing, roof will contribute to the rapid heating of the air in the room.Moreover, the lack of insulation contributes to the formation of condensation.
worth noting that roofs - slightly different concepts.It should be brief in this deal.Roof - is the entire top is usually non-residential part of the house, but the roof - its component share, the direct overlap of the dams (vaults).
Regardless of the material from which the house is built, sealing overlap occurs is similar to the warming of the facade of the algorithm.If the event is carried out in the course of construction, the problem with it is practically not.But a far more complex issue is operated roof insulation.It is necessary to consider some of the common features of this process.
most commonly performed insulation of the roof from the inside.The procedure includes not only laying the heat insulating layer, but also the use of many other materials.With their selection should take into account the set of climatic and natural factors (intensity of rainfall in these latitudes, wind, temperature, humidity and so on. N.).The availability of the attic and the extent of its use depends on a complex of works on the roof insulation.
Processing is carried out before starting work on the insulation of the roof.Major or partial repair of the roof (vault) is required.It further reduces costs and protects tenants from atmospheric phenomena.It is also necessary to carry out the replacement of decaying and leaking roof parts, antiseptic, a full check on the wiring, and other necessary activities.
Warming of the roof has some differences, depending on the configuration of the roof, because it is pitched and flat.The latter can be sealed from both inside and outside, but pitched - only from the inside.Consider
still improve the performance of the roof in the last version.It involves applying the following layers:
- Waterproofing.If the roof is not waterproof barrier between the rafters and the roof, you'll need a little work on it, because his presence is necessary.Gidrobarer envelop around lines and fixed braces.
- insulation.For the application of this layer is better to use mineral wool.Requirements for it are minimal.Its thickness should be less than 100 mm, it should not exceed the diameter of roof racks.Laying tiles should be carried out on the slope below.Mounting fixed with nylon cord or rails.
- Vapor.Parobarer mounted on top of a layer of insulation.Steam and waterproofing is recommended by the use of construction of the membrane film.Conventional plastic is unsuitable, because has no perforation.
As it comes to roof insulation, it is necessary to specify the two main materials used in such cases, namely:
- rockwool.
- Glass wool.
latter has characteristics worse, worse because it retains heat and not very environmentally friendly.
For roof insulation can be used, and other materials, but they must meet the following requirements:
- have low thermal conductivity.The material should as much as possible prevent the loss of heat.This will be particularly oschuschutimo in places of close contact of insulation from the street.
- ease.A large load on rafters is unacceptable for many reasons.
- Fire protection.We are not talking about the complete fire resistance, simply by heating the surface of the roof, or as a result of any other impact insulation should not actively react.
Thus, we can conclude that the insulation of the roof is a relatively simple task, although it has some features and requires significant material costs.
