Steico multi membra 5 is a vapour control layer for creating an airtight seal internally.
Key points :
Particularly robust and flexible
Highly tear-resistant
Permeable, sd value 5 m
Suitable for air-injected insulation and insulation batts
Suitable for sub and top installation when sufficient insulation covering is provided by STEICO wood fibre sarking boards
Specification :
Width: 1.5m Length: 50m Roll Coverage: 75m² Roll Weight: 130gm² sd value: 5 Temperature resistance: -40 to +80 °C UV protection in non-installed state: 3 Months Max. tensile force longitudinal: 350 Max. tensile force transverse: 350 Elongation at Max. tensile force longitudinal: 20 % Elongation at Max. tensile force transverse: 20 % Tear resistance longitudinal: 270 N Tear resistance transverse: 270 N Fire Rating: Class E according to EN 13501-1
Application:
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
