Louvres

2016 Louvre Brochure

We have been manufacturing and selling louvres globally for over 60 years. When you specify our systems, you get the support of a dedicated team with a wealth of experience and design capability.

The performance of our louvres has been evaluated by independent third party testing. In addition, any of our standard or bespoke solutions can be verified in our own testing chamber to ensure they achieve specified performance levels in real world conditions.
