VARA FLUID Spray is a is a humidity variable airtight vapour control layer (AVCL) designed to ensure seamless airtightness in both new build and retrofit projects.

Features and benefits:

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 and durable.
LOW VOC polymer-based liquid.
Class W1 resistance to water penetration.
Excellent adhesion on various surfaces .
Fast application – speeds up construction.
Ready-to-use product – vertical or horizontal application.
