SLV-S - 'A' Class Vertical Blade Storm Louvre

Key Features

The vertical blade SLV provides a dramatic alternative to the ‘normal’ concept of louvre systems. The vertical blade design gives the designer freedom to exploit vertical dimensions within ventilation systems.

A major benefit for our customers is cost saving: no longer is it necessary to have double or triple bank systems to prevent water ingress - it can now be achieved in a single bank, single frame style, and with better results.

The remarkable performance is due to the carefully researched profile – this allows air to pass, but diverts and captures water particles and prevents water ingress even under the most extreme conditions of test.

Manufactured in Britain.
