Seals the System

Flexi- Flange creates an airtight seal along the wall and floor joint in the basement. The FinishShield Vapor Barrier is neatly secured along the flange creating seamless barrier from moisture and water.

Protective Flange

Flexi-Flange protects the FinishShield Vapor Barrier from lime and mineral deposits than can deteriorate the vapor barrier over a period of time.

Flexi-Flange is an integral component of the GrateDrain system. It assists in creating a truly closed system. Flex-Flange seals the basement environment from moisture and water and does not allow it to evaporate back into the home. Flexi-Flange is added protection from harmful gases and minimize the infiltration of insects.
