Application

Suitable for applications requiring screening and ventilation.

Description

Single bank extruded weather louvre, providing high performance rain defence. Suitable for applications requiring screening and ventilation.


Features and benefits:

  • Highly aerodynamically efficient, reducing air resistance, allowing the plant and the aperture to be minimized thereby saving running costs.
  • Durable and maintenance free – UL is completely made from corrosion-resistant materials.
  • Thermal expansion of the louvres enabled – the louvres are clipped (and not riveted or screwed) to structural supporting mullions.
  • Proven performance, tested to EN 13030:2001.
  • Easy to install: can either be delivered to site pre-assembled or as a kit of parts.
  • 50 mm pitch.
  • If noise reduction is required, acoustic louvre panels can be placed behind EWL.
