Before starting to insulate the house, you need to tunisia mobile database which side of the brick wall will be insulated, external or internal. It is more effective to insulate the house from the outside, since the thermal insulation properties of the brick structure are preserved, and the risk of condensation is reduced. To calculate the amount of necessary materials, the area that will be covered with penoplex is measured. To the resulting number, add 3-5% for trimming (depending on the complexity of the structure). Most often, blocks with a density of 25 kg / m3 and a thickness of 100 mm are used.

To ensure better thermal insulation, it is recommended to lay the sheets of penoplex in 2 layers. In this case, the thickness of each sheet is selected based on the calculation of half of the final desired result.

How to prepare brick walls for insulation with penoplex?
Before starting thermal insulation measures, it is necessary to ensure the appropriate quality of the coating of the external walls of the house. For this, the following work is carried out:

Alignment of external walls.
Removal of debris and dirt from the insulated structure.
Priming the surface of the room for better adhesion with the mortar.
Treating the wall with an antiseptic against fungus and mold.
Installation of penoplex
