Room-in-roof - Insulation of the slopes between rafters

Detailed steps




Basic rules of implementation

1

Store rolls and batts in their original packaging, protected from rain and direct sunlight.


2

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.

3

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.

4

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).

5

Install a finishing facing with maximal fire rating (mandatory).
