If your balcony is not glazed, you did not finish the balcony with plastic panels, and you want to insulate it, then first you need to install a metal profile. This is done using a drill and screws with a drill. Self -tapping screws should be so long that they drill through the required surface through, and there is a supply for convenience. Choose German production screws and do not save their number.
After installing the profile, fill the space with mineral wool or polystyrene foam for insulation. The inner surface of the balcony can be sheathed with wood or metal. After that, you can install plastic double -glazed windows. They protect the space from excessive moisture, in winter from the cold, and in the summer from the heat. To make the balcony even warmer, you can insulate the floor. To do this, replace the old screed with a new heat -insulating.
Such a screed will provide reliable thermal insulation even in the most severe winter. Before applying a new screed, remove dust and the remains of the old solution from the surface. Set the beacons, pour the floor with a heat-insulating screed with a layer of 10-15 cm. Right remove excess solution, let it freeze. After that, apply a layer of self -leveling mastic so that the floor becomes perfectly even. Now the balcony is insulated as much as possible.
