WL38 Louvres are designed for use in all situations where an external ventilation terminal is required. With a high 50% free area, the same as that shown across the whole range of HVC standard weather louvres, and a unique blade profile designed specifically to prevent the ingress of rain, performance and aesthetics are assured.
Being the smallest format weather louvre available from HVC, WL38 louvres are normally used when hole size is less than 600mm square. This combines with the lightweight, small profile blade to make a louvre which is easy to install and does not place large stresses on its supporting structures.
Suitable for both supply and return applications, WL38 louvres offer good levels of rain protection in almost all weather conditions.
