Print E-mail

The Nationwide Louvre Company offer a full range of Specialist Louvre shapes.

Including ellipses, diamonds, triangular louvres, arched louvresand louvres with cut outs, specialist louvre shapes are available to order, whatever your specification we can design and build for purpose.

Nationwide Louvre Company construct our louvres entirely from high quality HETF aluminium extrusions, fabricated and tig welded for strength of construction and manufactured to suit varying depths and applications with blade sizea of 34mm, 50mm, 75mm, 100mm and 150mm.

Specialist louvres are not manufactured to a standard size, any panel size can be created by joining individual panel modules and then finishing with a full range of polyester powder coatings colours which are suitable for external mounting. These are applied with a Aluchrome pre-treatment to give a guaranteed life expectancy of 10 years of semi-glossapplications and 12 years for gloss applications. Other PVF2d SynthaPulvin are available at varying costs.  Specialist Louvres can be fixed using various fixing methods, for specific details or a free quoteplease call us on 0870 443 1923.
