Aluminium external louver for protection against rainwater penetration
Robust
Mechanical Stability
Effective Rainwater Separation
Range of Finishes
The PZAL Louver is intended to protect the outside supply and exhaust wall openings against rainwater penetration.
The PZAL Louver can be installed into a duct with a mounting frame and screw or onto the wall by bending the legs of a mounting frame.
The unit is available in a vast range of colours and finishes to suit different installations.
The PZAL external louver provides effective protection to the outside supply and exhaust wall opening against rainwater penetration. Water is blocked from entering the duct with air speed up to 3/ms. The PZAL also effectively blocks the view into the inside of the duct. The product is ideal for building facade ventilation transitions for air supply or extraction. The PZAL external louver has a robust design and construction, ensuring mechanical stability.
The unit is manufactured from extruded aluminium profiles. The product consists of an outer frame, an inner frame with a built-in ledge, blades with 34,5 mm spacing and can be equipped with an "S" welded mesh screen (raster 10 mm × 10 mm) and mounting frame.
The ledge prevents water penetration across the louver frame. The welded mesh screen provides protection against large impurities, such as leaves. The mounting frame contains screw openings for easy installation into the end of a duct and bendable legs for easy installation into a wall. Other sizes are available in this range.
