Vario Double Fit Mastic 310ml

Vario Double Fit Mastic is a 2-in-1 solution, used for creating air-tight joins between vapour membrane and adjacent surfaces. Supplied in a 310ml tube. 

• 2 layers of adhesive within the mastic provide added flexibility after application.
• As part of the Vario system - prevents mould and mildew growth by reducing the potential for moisture accumulation
• For renovation projects, especially loft spaces and roofs, Vario together with mineral wool insulation dramatically improves the thermal performance of an older building.
• Vario allows timber dampened by rainfall during construction to dry out faster.
• Vario automatically adapts to long heating and short drying periods, unlike conventional membranes that behave the same way in all conditions.
• Vario protects the inside of the building against toxic gases - particularly important when converting the attics of older buildings into living space
