DESCRIPTION
The 452V louvre is a built-in wall louvre with large chevron section V-blades and excellent watertightness (class A, up to 1.0 m/s according to EN13030).

Extruded, L-shape, aluminium frame profiles with a total height of 64 mm are cut at mitre of 45° and assembled through compression and a clamping corner.

Aluminium blade supports are pop-riveted to the perforated vertical frame profiles.
Louvres with a width over 700 mm are provided with an extra perforated U-profile to fit supplementary blade supports for reinforcement.

The extruded aluminium blades are clipped into the blade supports. The distance between the blades is 66 mm. The blades are V-shaped, allowing no see-through visibility.

An anti-static 304 stainless steel 6 x 6 mm mesh wire is tensioned tight inside the frame using a nylon wire.

The finish can be anodised (natural) or powder-coated (any RAL colour).

Minimum dimensions are 305 x 305 mm (WxH)
For larger sizes, multiple 452V louvres may be linked together on request.

The louvre is optionally available with a frame without flange.
