Injection is used to insulate walls, partitions or intermediate floors. The walls to be insulated are made up of closed cavities that will keep the insulation in place. They are pierced at the top, in the centre of each cavity, to enable the injection pipe to pass through. Filling is performed from bottom to top while observing the density.
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).
