In the case of old residential buildings, the only way to isolate the apartment thermally from outside is to adapt the entire building. However, in conditions of collective housing, where it is necessary to collect the consent of all tenants, as well as significant funds, this is not always feasible. The insulation of the interior walls equally successfully prevents the loss of heat, as well as the insulation of the exterior. The spray foam insulation toronto is what you need today.

The advantage of internal insulation is a smaller price per square inch than the outside. Thus, if glass wool is taken for external insulation as a material, the price of 10 cm thick insulation will be about 15 dollars per square meter. Internal insulation with the same material about 5 cm thick, will cost twice as much. The prices are even lower if it’s done with styrofoam: about 10 dollars for the outside, and twice less for the interior by one square meter. The disadvantage of internal isolation is the creation of a so-called thermal bridge. These are the joints between the insulating wall and other, non-insulated parts of the building. In these parts, condensation and molding occur, which usually occur in the corners of the rooms. What needs to be kept in mind is that the total area of ​​the room will be somewhat reduced, but also the consumption of electricity will also be reduced.

External insulation of the building

If you notice in your house some of the following problems: cold in the room even though it is warmed up; fast cooling of the house after the end of heating; the occurrence of mold, moisture, condensation and fungi, then it is time to start the installation of the thermophase on the object. Experts advise contact facade (demit). They are the most common type of thermal protection, where the insulation is attached directly to the wall of the building from the outside. In addition to ensuring weather protection, they can also contribute to the durability of the wall itself. The stone wool is most often recommended, because of all the advantages it provides.

In addition to her, the contact facade consists of – the anchors, which mechanically attach the stone wall plate to the wall, due to the additional security of the entire facade; adhesives, which are used for gluing facade panels for the substrate; moldings, which are necessary because they additionally provide the angles of the objects, openings and places where water is expected to be poured; mesh, used as a reinforcing layer; a substrate, which serves as a basic coating and ensures color uniformity and, finally, a finishing layer, which serves as a decorative finish of the façade system. Before starting work, the façade surfaces must be dusted to ensure good adhesion. The price ranges between 15 and 20 dollars per square meter, depending on the thickness of the board.
