Room insulation with polystyrene foam

To ensure a comfortable stay in an apartment in the winter, owners veneer rooms with insulating coatings, among which are widely used sheets of expanded polystyrene. The internal structure of their material unable to destroy microbes, fungi, chemicals, ultraviolet rays and other environmental factors. But after wall cladding with these products, the temperature of the heated space accelerates, moisture condenses and the area of ​​the room decreases.

Styrofoam wall insulation technology

If the owner of a residential apartment decides to insulate the walls of the room with the material in question way to prepare the surface. When performing this event, large irregularities are filled with mounting foam, and cracks are subjected to more complex processing. They expand and lose the remaining debris, moistened with water spray and filled with tile glue mixed with plaster in a ratio of 1: 1.After painting the gaps, the walls are finally covered with a leveling compound. The rows of polystyrene plates are mounted using adhesive technology on a perfectly prepared base, and the work proceeds from the floor level to the height of the ceiling. To improve the reliability of their fixation, it is recommended to use a solution of polyurethane adhesive for internal work. The first rank of insulation products is fixed at a short distance from the floor, and the dimensions of the sheets are adjusted to the peculiarities of the base by cutting the material.

Glue is used to process the perimeter of the product, which is then applied to a surface of 200 mm from the adjacent plate and pressed down before the occurrence of a gap of 50 mm. The independent movement of the plates, which occurs before the glue hardens under the influence of gravity, is prevented by plastic dowels with a wide cap. Before installing such products, the intersection of gaps between adjacent elements of the heat insulating cladding is equipped with a hole with a width later than the dowel that twists into it.

The length of the fixation element must match the thickness of the sheet, and the seams between the fixed polystyrene foam must be sealed with foam. An excess amount of hardened sealant is cut with a paint knife and the installation of a vapor barrier of foil-coated polyethylene begins, preventing moisture condensation, reproduction of pathogens and the spread of harmful fungi.

Butts of this material with a minimum thickness of 0.2 mm are butt-locked with the foil side to expanded polystyrene on the entire surface of the base to be insulated, and the remaining gaps are sealed with adhesive tape, which is equipped with a foil layer. To improve the property of aesthetic appeal, the surface equipped with a vapor barrier film is covered with plaster mortar. Before work, a fiberglass mesh with cells of 5 mm size is laid, which increases the adhesion strength of the solution with the base.

The canvases of this material are fixed with an overlap of 100 mm and attached to the insulated walls with plastic dowels. The mesh is processed with glue, the layer thickness of which must correspond to 2 mm, and the corners are equipped with metal profiles. In order to gain an aesthetic appeal, the walls, insulated according to the technology considered, undergo final finishing and installation of decorative coatings that are compatible with the interior design style.
