Blowing is used to insulate cold or inaccessible attic spaces (e.g.: prefabricated roof structure made of industrial trusses). Insulation application involves blowing Jetfib’ cellulose wadding on the floor or suspended ceiling between the tie-beams. Jetfib’ouate is packaged in 10 kg bags (40 bags per pallet): 2 pallets are required to insulate with 240 mm thickness over 100 m2 (corresponding to R
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).
