Construction Specialties Storm Resistant Louvres repel up to 100% of wind-driven rain. Available in both horizontal and vertical configurations.
Ideal when you:
- Need 100% resistance to wind-driven rain
- Expect winds as high as 50 mph that drive around 20mm of water per hour
- Must integrate the louvre into the building’s total design or house them behind architectural grilles, detailing or continuous-line louvres
- Can’t use a plenum due to cost or space considerations
- Plan to house sensitive equipment adjacent to the louvre system
- Need a louvre to integrate with a CENTRIA Formawall® Dimension Series® panel system
