The light building walls are made up mainly of a metal framework, covered with a facing (wood, gypsum, Fermacell, etc.) on either side. Distributive partitions (used for distributing the rooms within the same dwelling) are differentiated from separating partitions (for separating two dwellings). The difference between the two is found in the associated thermal and acoustic requirements.
Store rolls and batts in their original packaging, protected from rain and direct sunlight.
Cut the insulation to the required width between supports, with an excess of 2 cm, and place the insulation under gentle compression ("spring effect") to ensure perfect contact with the uprights.
To ensure continuous insulation, take special care when sealing the joints between walls (wall / floor / slope) and checking that the strips are in perfect contact.
Ensure the maximum seal of the insulation by installing an offset, continuous vapour barrier on the inside (hot) and a roof-boarding screen that is pervious to water vapour on the outside (cold).
Install a finishing facing with maximal fire rating (mandatory).
