Processing STEICOmulti membra 5
- Lay the membrane or sheet so that the printed side is facing the fitter
- Lay the sheet parallel or at a right angle to the rafters wirh an overlap of at least 10 cm
- Ensure flush-processed bay insulation. There may be no cavities between the bay insulation and sheet/membrane. Visual check thanks to translucent character
- Fit the membrane or sheet in a tension-free manner and avoid creases
- Overlaps, component joints and penetrations must be made in an airtight manner by means of STEICO system accessories
- Additional mechanical fastening (e.g. battens) must be used immediately after installation to support the weight of the insulation
Processing in case of air-injected insulation:
- The distance between the clips to be used for fixing the vapour barrier in place on the supporting structure is max. 10 cm
- The use of STEICO fibreboard strips or an additional lath along the rafter is recommended as an alternative
- Before the introduction of the air-injected insulation, cross lathing must be arranged with a max. centre distance of 420 mm
- Once the insulation has been injected, seal the injection holes in an airthight manner using STEICOmulti tape P stickers
