Louvres are an essential part of ventilation systems, and are almost always visible from the outside, so why not make them compliment the building?
HVC's range of standard louvres comprising 38, 50, 75 and 100mm pitches is designed to blend excellent aesthetic qualities with high performance airflow and rain protection capabilities.

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.
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.
At HVC we pride ourselves on our ability to manufacture to our customer's specification, whatever that may be. Whether we are asked for a standard square WL38 weather louvre, or a triangular unit painted to a specific RAL or BS colour, we will always deliver.
With HVC, options really are optional. You will never be changed for a feature you do not want. That is not to say we do not offer a wide range of options however: Bird and insect mesh is an easily installed option, but can make a huge amount of difference once installed. Also, more complex set ups comprising a WL38 and volume control damper are regularly manufactured. With HVC you can be assured of finding exactly what you need.
