How to insulate the basement at home

In almost every private house there is a basement - a room located at the bottom of the structure between the level of soil and overlapping. More recently, the basement space was exploited exclusively as a household room (for storing conservation and working equipment), it is placed on garages and workshops, wine cellar and billiard rooms, work offices and libraries, gyms and relaxation rooms.

Regardless of how you plan to use the basement, it must be insulated. The crude and cold basement actually "steals" the heat designed to heat the house. High-quality and timely thermal insulation "underground" will help to significantly save on the payment of heating and electricity. In addition, the insulation of the basement contributes to the overall improvement of the microclimate in the house - it stops the drafts, prevents the development of the mold dangerous to human health and the appearance of specific sharpening odors in the residential zone.

You can warm the basement walls both from the inside and outside. A continuous external heat insulation is considered to be more practical and effective, since the inner insulation of the basement walls is fraught with condensate formation in places of wall connection and insulating material. The external insulation of the basement starts during the construction of the house, at the end of the construction of the waterproofing of the foundation, the installation of the drainage system, ventilation and drainage.

For the external insulation of the walls, polystyrene foam is most often used - this dense and simultaneously lightweight material is characterized by low thermal conductivity and excellent moisture resistance. You can begin to lay panels in 5-7 days after the external waterproofing. Before mounting the insulation, the walls twice are treated with facade antiseptic primer.

For fastening the material, a special solution is used - cold mastic. The adhesive composition is damaged across the entire area of \u200b\u200bthe plate, after that each panel is tightly pressed to the working wall and retain in a fixed position 30-40 seconds. All gaps and joints between the plates are filled with mounting foam. The surface of the insulation, which is placed below the soil level, is necessarily treated with water-repellent mastic. Asbestos-cement smooth plates are mounted on top of the polystyrene. Such an outdoor thermal insulation reliably protects the walls of the basement from freezing and mechanical damage.

To the subsequent stage of the insulation of the basement - the heat insulation of overlaps - you can begin at the end of construction work. First of all, the ceiling surface is thoroughly cleaned from dust and dirt. After that, close all the joints, cracks and seams. Speakers on the surface of the overlap of pins, nails and other metal fasteners are treated with sealant. The optimal insulation for the basement ceiling is mineral wool (the recommended sheet thickness is not less than 90 mm). For the insulation fastening, tile glue based on cement is used. Having completed the laying of Minvati, the ceiling is plastered and lined with a suitable material. Of course, after mounting the ceiling insulation, the height of the basement will decrease slightly, but the floors in the residential part of the house will always be warm.

The insulation of the floor in the basement is starting with alignment of the base and laying of waterproofing materials. The most reliable is the coem (elastic cement-based elastic formulations) and rolled (dense polyethylene, rubberoid) waterproofing. Next lace heat insulation - polystyrene foam panels. All joints between the stoves and walls are sealed with mounting foam. The final barcode is the fill of the concrete screed over the insulation and laying the finishing coating. Such a layered cake allows you to simultaneously reduce heat loss and protect the room from groundwater tide.

For internal insulation of walls, foam or all the same polystyrene foam is used. Plates are mounted on the prepared base - all the walls must be smooth, clean and treated primer. The insulation laying is starting from below - from the floor of the room. As with the outer heat insulation, adhesive solutions are used to attach panels. Additionally, the insulation is fixed with plastic fungal dowels. To avoid the formation of cold bridges, seams and gaps between the sheets of thermal insulation are filled with mounting foam or sealant.
