Cupolex Windi

CUPOLEX® WINDI® creates a ventilated floor in new or remodeled buildings without affecting the structure of the building. The adoption of CUPOLEX® WINDI® allows you to save on waterproof sheathing and guarantees a constant seal against dampness. CUPOLEX®-WINDI® may also be easily attached to walls to create a void capable of ventilating and eliminating mold or installed to create ventilated flat or pitched roofs.

CUPOLEX® WINDI®, protects the upper concrete from the rising damp, while the void created underneath can be mechanically or naturally ventilated to eliminate humidity and/or gasses.
