The Ventüer VL-2SD ventilation louvre system is an excellent rain defence louvre. Rated as Class A under BS/EN:13030 for air volumes up to 1.5 m3/second, and Class B for air volumes up to 3.5 m3/second it is ideal for exposed locations where high wind speeds and levels of rainfall can be expected.
The VL-2SD louvre blades are supported on a two-piece pressure equalised mullion system, and bordered by a 150mm frame that ejects captured water to the front of the panel. It shares the same support frame as the VL-3SD, VL-50CM and VL-100CM, and can be combined with these products to provide cost saving configurations. The standard frame can be fixed in to a wide range of primary support structures and cladding types, including profiled metal cladding, fibre cement sheet, window joinery systems and others.
The Ventüer VL-2SD can be fitted with a sealed solid backing panel to provide a water-tight rainscreen in areas where the louvres are "inactive", or not required for air flow. It can also be fitted with bird or insect mesh, and can be coupled with the Ventüer range of air control and fire dampers.
