Width: 1.5 meters
Length: 50 Meters
Area: 75 Squared Meters
SD Value: 0.025 m
Application Area (External):
- Pitched roofs
- Ventilated closed facades
Purpose in an Airtight Building Envelope:
As a ‘highly vapour permeable’ (breathable) membrane, the OMEGA LIGHT enables the weathertightness of your building, while at the same time allowing for water vapour to pass. Hence preventing moisture to be trapped in the walls, which leads to condensation, rot, mold and overall degradation of the walls, roof. Unlike a vapour closed building wrap, Omega Light weather tightens your building while allowing for moisture to escape and walls to dry.
Advantages:
- Anti Glare
- Anti Slip
- UV-Stabalised
- 3-layer fleece combination, very tough and durable during installation and on the job site
