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