Processing guideline
INFO
Vapour barriers can used with wall, roof and ceiling construction elements as an airtight layer and as a vapour retarding layer.
(1) MECHANICAL ATTACHMENT OF THE VAPOUR BARRIER
The vapour barrier is usually attached transverse to the position of the rafters, joists or beams with the smooth and/or printed side facing the installer. The lengths are fixed mechanically to the construction’s wood with approx. 10cm overlap using tacking staples. For metal C-studs a temporary attachment using double-sided adhesive tape or even a spray-on contact adhesive is a possibility.
(2) AIRTIGHT ADHESION
Airtight adhesion of the joints, connections and penetration points must be carried out using the AIRSTOP Adhesion system.
(3) TRANSVERSE LATHING / MOUNTED AT INTERVALS
The laths underneath the vapour barrier have to be mounted before the cellulose is blown in. The centre distance shall be less than ≤30 cm. The joints of the vapour barrier also have to be covered by an additional lath. Glued connections and joints that were under tension have to be mechanically secured. The membrane has to be applied without tension.
(4) LONGITUDINAL LATHING
When no transverse lathing is used, e.g. if formwork is installed on longitudinal lathing, the vapour barrier must be placed parallel to the rafters or to the construction. The joints must lie on the wood of the construction and be stapled overlapping and sealed using AIRSTOP adhesive tape. Before the insulation is blown in the longitudinal lathing must be mounted to provide mechanical relief of the joints.
