It is best to warm the roof toinstallation roofing, because it is more efficient and easier way. Unfortunately, this is not always possible. The reasons for this may be many - for example, an unexpected change in weather conditions, which can harm the structure. That is why it may be necessary to warm the roof from the inside.
In order to do all the work at the levelfollow some simple rules that are the same for cases when using both mineral and ecological insulation. During the installation procedure, make sure that the ventilation gap is open. If a special under-roof membrane is used, attach the insulation close to its surface. So the material will closely adhere to the film, but it should not lift it above the rafters, because the ventilation gap will be closed. There should be two. One - above the membrane, and the other - under it. In order to check the desired distance between the insulation and the film in one centimeter, pull a special limiter.
Place the joints of sheets of insulation in chessorder in adjacent layers. If they are about twenty centimeters thick, it is better to place them not in four layers, but in two by ten centimeters. In order for the insulation to fit snugly to the rafters, its width must be slightly larger than the distance between them. Used in the installation of natural materials are much less prone to crushing and more resilient than those that are made on a mineral basis. Applying an eco-friendly insulation, you can allow small irregularities on the edges.
Ensure that the insulation boards are tightadjoined not only to the rafters, but also to each other. If there are even small gaps, frost may form in frosty weather, and after it starts to melt, the roof will leak. If the roof is being insulated from the inside in the presence of rafters with a large pitch, additionally fix the insulating material from the side of the room. This will help wire. Attach it to the rafters with self-tapping screws, and further insulation will be maintained by the installed crate.
В случае, когда конструкция не позволяет make insulation with sufficient thickness, use the following scheme: perform roof insulation from the inside between the rafters and under them. Across the wall attach the crates from the side of the room, between which place an additional layer of insulating material. This method is quite effective, since the rafters will be completely covered with insulation.
When using material based on mineralfibers organize vapor barrier from the premises. Do not save in the process of choosing a film, as possible damage and defects can lead to loss of efficiency insulation. This occurs after over-wetting of the material from mineral fibers. In addition, pay special attention to the installation of the film, as well as pasting joints between it and the structure. Carry out the insulation of the roof from the inside as carefully and accurately as it will depend on the comfort of all living in the house.
