best done before the installation of roof insulation roofing, because it is more efficient and simple way.Unfortunately, this is not always possible.The reasons for this may be many - such as a sudden change in the weather, which is able to harm the structure.That is why it may be necessary insulation of the roof from the inside.
To perform all work at, observe some simple rules that are the same for cases when used as a mineral and ecological insulation.Through the installation procedure, make sure that the ventilation gap has been opened.If you are using a special under-roof membrane, insulation mount flush with the surface.So the material will adhere closely to the film, but he does not have to lift it above the rafters, because the ventilation gap will be closed.There should be two.One - over the membrane, and the other - under it.In order to check the correct distance between the heater and the film one centimeter, pull the special delimiter.
Place the sheets of insulation joints staggered in adjacent layers.If they have a thickness of about twenty centimeters, better not to place them in four layers, but in two of ten centimeters.To insulation tightly to the rafters, its width should be slightly greater than the distance between them.As used in the installation of natural materials are much less prone to breakage and more resilient than those made on the basis of mineral.Using eco-friendly insulation can allow small bumps on the edges.
Make sure that the insulation boards abut not only to the rafters, but also to each other.In the presence of even small cracks can form frost in the freezing weather, and after it begins to melt, the roof leaks.If the insulation of the roof is carried out in the presence of the rafters inside a big step arrangement additionally secure the insulation material from the premises.This helps wire.Attach it to the rafters with screws, and in the future will support the installed insulation sheathing.
Where the design does not allow insulation with sufficient thickness, use the following scheme: follow the insulation between the rafters of the roof from the inside and underneath.Across attach the batten bars from the premises, between which install an additional layer of insulating material.This method is quite effective, as the rafters are fully covered with insulation.
When using materials based on mineral fibers arrange vapor barrier on the room side.Do not skimp in the selection process of the film, as any damage and defects can result in loss of insulation efficiency.This occurs after moistening the material of mineral fibers.In addition, focusing on the installation of the film, as well as pasting of joints between it and the design.Spend insulation inside the roof as carefully and precisely because of this will depend on the comfort of living in the house.
