Insulating materials – plates and mats.
The main task of insulating materials is to prevent heat loss and suppress noise. Mineral wool (glass wool and basalt wool) and foam (mostly white polyester rigid foam) are used to insulate partition walls, attics, ceilings, etc.. Depending on the purpose, you can buy these materials in various forms, e.g.: mineral felt as rectangular plates, wedges or in rolls as long mats with or without aluminum foil, foam material also as ceiling slabs with a decorative pattern or under wallpaper with or without a cardboard surface. Moreover, both insulation materials can be combined with plasterboards. (Their advantage is this, that after arranging these elements, we can wallpaper them immediately, paint or lay the glaze). Natural material such as cork also has excellent insulating properties. Can be used as a wall plate, floor or ceiling. Aluminum or polyethylene foil is used e.g.. when insulating sloping roofs, where, in combination with mineral wool, it is used as a sealing layer, if the sealing material is not provided with it. The individual foil strips can be connected with self-adhesive tape.
Flat roofs covered with bitumen tar paper are difficult and expensive to maintain. There are many options for solving this problem. The most radical solution is to build a gable structure. But it can be cheaper, np. using liquid foil. It is easy to use and very effective in operation. The roof should be cleaned of peeling parts of the roofing felt and dried completely. Then the liquid foil is poured and thoroughly spread over the entire surface with a rubber squeegee and a paint roller. Approx 1 kg of foil per m2. On the second day, we use approx 0,5 kg for one more layer. Because this fluid after 6-12 hours, it will form a foil layer of the order of ductility 400%, no protective layer is needed anymore. Only on particularly complex corners and connections is a layer of acrylic fiber applied to the still wet foil.
