Partel Varafluid Brush - Fluid Applied Membrane 5.5Kg

Partel Vara Fluid Brush is a humidity variable air and vapour control layer (AVCL) engineered to provide superior airtightness for long-term performance of the building envelope. Vara Fluid Brush is a water-based air and vapour control layer (AVCL) that can be brushed, providing a continuous airtightness over cracks and gaps in both new build and retrofit projects. Advanced hygrovariable technology allows incredible summer drying conditions, but can equally protect the construction in winter.

• Innovative liquid airtight membrane that changes vapour permeability according to the ambient relative humidity (RH)
• Ensures optimum moisture flow through building structures with a Sd range of 0.15m to 16m
• Hygrovariable Technology – Extremely safe airtight system
• Low VOC polymer-based liquid
• phA Class Passive House Certified airtight system, featuring an air permeance value of 0.00 m³/(m²h)
• Ensures adequate coverage (cracks and joints up to 2 mm)
