MAESTRA’s technology stops air infiltration with the Interlock™ system.

Interlock™ system

Our copper Interlock™ weather stripping provides a better seal to prevent air from entering thanks to its lock-and-key design and a contact surface that’s three times larger than conventional weatherstrips.

In addition to Interlock™ copper weatherstripping our doors are also equipped with a second side weatherstripping for maximum protection.

The edges of the floating panels are sealed with a non-drying butyl that keeps the panel sealed while allowing it to contract and expand with the temperature.

The invisible multi-strip brush system, combined with our waterjet molding, seals out even the heaviest rain to provide the best leak protection out there.
