Polycarbonate Blades Series 
A new product has recently been developed to complement the existing metal louvre range, a ventilation louvre with polycarbonate blades.

Application
The louvre blades are replaced with a formed polycarbonate blade which gives both ventilation and light. The main application for this combination are public access areas which need to be well illuminated, e.g. stairwells in blocks of flats.

The louvres were tested at BSRIA and provides the same performance as a standard metal blade louvre.
