1. Lay the membrane or sheet so that the printed side is facing the fitter
2. Lay the sheet parallel or at a right angle to the rafters wirh an overlap of at least 10 cm
3. Ensure flush-processed bay insulation. There may be no cavities between the bay insulation and sheet/membrane. Visual check thanks to translucent character
4. Fit the membrane or sheet in a tension-free manner and avoid creases
5. Overlaps, component joints and penetrations must be made in an airtight manner by means of STEICO system accessories
6. Additional mechanical fastening (e.g. battens) must be used immediately after installation to support the weight of the insulation
