Aluminum 400 Series
Rainscreen Design for Superior Water Protection
The 400 Series windows are designed according to rainscreen principals for superior water proofing in mid- or high-rise commercial buildings. Perfect for use on both new constructions and replacement applications.

True Rainscreen Performance
In preventing water ingress and the resulting damage, a true rainscreen window incorporates four critical barriers:
Vapour barrier – limits condensation of interior moisture
Air barrier – works with vapour barrier for moisture control
Water shedding – directs water away from building
Exterior moisture barrier – final line of defense
