Airtight penetrations and edge connections
Penetrations and connections must also be airtight.
Levelling must be carried out on uneven surfaces when making connections.
Power and loadfree connections
Ensure that edge connections are power and loadfree when processing.
Dirt and dust
Materials, connections and surfaces to be bonded must be cleaned if necessary to ensure that they are clean, dry, and dust, grease and ice free.
Grid when blowing out with cellulose fibres
Support the membranes with a grid made of battens measuring approx. 65 × 65 cm.
Attaching the vapour retardant
Attach the vapour retardant to the underlying construction using staples.
Lay the vapour retardant avoiding bulges and creases.
In critical areas ensure that a hard base is available.
