Visqueen Vapour Barrier 300mu | 2m x 50m Single Wound AVCL

Visqueen Vapour Barrier is a heavier gauge air and vapour control layer (AVCL) for buildings with a medium risk of condensation. At 300 micron, it has more than double the vapour resistance of Visqueen Vapour Check. This makes it a good choice where internal moisture levels are higher or where the specification calls for a more robust barrier.

It restricts warm, moist air inside the building from passing into the floor, wall or roof structure. This protects insulation and the building fabric and improves airtightness. The membrane is green tinted and semi-transparent, so studs stay visible. It is supplied single wound rather than folded, so it lies flat without fold lines. It is UKCA, UKNI and CE marked to EN 13984:2013.

Benefits

• Higher vapour resistance than lighter vapour checks
• Tougher sheet stands up better to site handling
• Flat, crease-free sheet from a single wound roll
• Improves airtightness and protects insulation performance
