BO-SA Membrane is manufactured from a coated, vapour-permeable non-woven material and acts as an effective barrier against driving rain and wind-driven snow. Its fleece surface helps drain moisture and driving rain safely and reliably away from the façade. The self-adhesive membrane is supplied with two- or three-part release paper, depending on the width, for fast and convenient installation.
Applications:
- Suitable for reliable exterior sealing around joinery and building elements including aluminium, timber, PU and PVC frames, curtain walling, window frames, OSB and plywood panels, façade cladding and connections to other sealing membranes.
- Creates a weather-resistant exterior connection and helps prevent the penetration of air and moisture at critical junctions.
Properties:
- High-performance self-adhesive surface.
- No additional adhesive required, allowing very fast and efficient installation.
- Most of the adhesive strength develops within approximately 60 minutes; full bond strength is reached after around 3 days.
- Easy to install, including on challenging substrates.
- Can be plastered over.
- A 20 mm acrylic adhesive strip can be provided on the plasterable section (BO-SA Plus version).
