Paint-on Airtight, Smart Vapour Control Layer Partel VARA FLUID Brush is a humidity variable air and vapour control layer (AVCL) engineered to provide superior airtightness for lon g-term performance of the building envelope. Why Partel VARA FLUID BRUSH? Innovative liquid airtight membrane that changes vapour permeability according to the ambient relative humidity (RH). This contributes to maximum protection in the building envelope where moisture levels are critical, allowing vapour to escape and dry the structure. Ensures optimum moisture flow through building structures with a Sd range of 0.15m to 16m Hygrovariable Technology – Extremely safe airtight system phA Class Passive House Certified airtight system, featuring an air permeance value of 0.00 m³/(m²h) Flexible – ensures adequate coverage (cracks and joints up to 2 mm) LOW VOC polymer-based liquid Class W1 resistance to water penetration Excellent adhesion on various surfaces Fast application – speeds up construction, especially for commercial projects Single component, ready-to-use product Technical Data SD VAPOUR VARIABILITY RANGE 0.15-16 @ 0.3mm EN ISO 12572 WATER RESISTANCE W1 EN 1928 UV RESISTANCE 3 MONTHS APPLICATION TEMP +5°C Application VARA FLUID Brush is an air and vapour control layer designed for use internally and externally on the warm side of insulation on wall, ceiling, roof and floor applications. It is easily applied, vertically or horizontally, with a paintbrush and dries to an airtight flexible coating. Suitable for: Application on various surfaces – masonry concrete, silicate, OSB, plywood etc. Wall, ceiling, roof and floor applications Externally vapour open and vapour closed structures Wall to floor connections Wall to ceiling connections Wall to timber connections General construction joints Residential and commercial buildings Documents VARA FLUID Brush Datasheet VARA FLUID Brochure Video Show more
