SA Flex Vapour Barrier

An SBS (Styrene Butadiene Styrene) modified metal lined membrane, designed to prevent water vapour from entering the roof system and causing condensation.

Features and benefits:

• The membrane has a high percentage of SBS rubber, high-strength fibre-glass reinforcement and monolithic aluminium foil throughout.

• The aluminium foil placed within the membrane offers a high level of vapour blocking, and therefore condensation building up in the roofing system.

• The membrane is reinforced with a high-strength fibreglass scrim. The strength provided by the reinforcement resists movement and has good dimensional stability.

• When the SBS rubber is properly dispersed throughout the high penetration asphalt, the rubber provides increased thermal shock resistance, UV protection, heat resistance, elongation, and low temperature flexibility. To ensure proper dispersion, a special high shear mixer is used in manufacturing.

Applications:

The membrane is used as a vapour control layer (VCL) for any of Garlands torch-applied or self-adhesive membranes to prevent water vapour from entering the roof system. It is fully compatible with SBS modified membranes. For lower side finishing with adhesive polymers: Cold applied. Consult manufacturer for details.
