3UL Rain Defense Louvres
3UL weather louvres are roll-formed triple bank louvres designed for applications requiring ventilation with the maximum degree of rain defence.
- Available in a wide range of options -shapes, configurations, materials, finishes and coatings – to meet the requirements of almost any project from a screening perspective.
- Aerodynamic efficiency reduces air resistance and therefore saves operating cost by allowing the plant and the aperture to be minimised.
- High resistance to rain ingress for enhanced weather protection.
- Manufactured from corrosion-resistant materials for durability and maintenance-free operation.
The allowance of thermal expansion of the louvres is designed into the product. Louvres are clipped – rather than riveted or screwed – to the supporting mullions. - Durable – tested to EN 13030:2001 for premier performance.
- Easy installation – available either as pre-assembled units delivered to site or as a kit of parts.
If noise reduction is required, acoustic louvre panels may be used. - Rain defence performance (to EN 13030) – Class A – up to 3.5m/s suction velocity. Triple bank louvres offer maximum rain defence.
