The attic must be insulated in any case, since it is through it that more than half of the heat from a residential building «leaves». If the attic is planned to be used as a living attic, then the developer will face a number of difficulties that can always be overcome, you only need to follow the instructions and follow all the rules. First, you should visually view the quality of the film imposed under the roofing.
Make sure that the film does not sag, and moisture does not accumulate in sagging areas, it is also necessary to check the integrity on the films on the aspect of damage or ruptures. All damaged elements are sealed, for this they use the mounting adhesive tape or a special soldering iron (depending on the type of film). If the flooring is already nasty on top of the film, then it is almost impossible to conduct a high -quality inspection, it remains to hope that it was carried out before the flooring was mounted. Further, installation rails arrive at the most extreme “legs” of the rafters, they are necessary in order to hold insulation sheets or stoves, and also necessary in cases where a film with low vapor permeable qualities is used.
