Vapour Membrane
Features & Benefits
- Low emissivity reflective surface enhances thermal performance of the structure into which it is incorporated (still air cavity required)
- Air and vapour control layer
- Triple ply construction incorporating an adhesive strip located on the outer edge of the membrane and follows the dotted overlap line
- Provides an airtight system when installed with sealed laps
- Excellent air and vapour resistance
- Integrated tapes for quicker installation and reliable effective joint sealing
- Corrosion and damage resistant reflective surface
- Helps to avoid condensation risk in accordance with BS5250 requirements
- BM TRADA independently certified for all applications
- Class 1 surface spread of flame to BS 476-7
