NAL300C Acoustic Louvre - 150mm blade pitch


NAL300C Acoustic Louvre - 150mm blade pitch

Key Features

Naco’s range of Acoustic Louvre panels have been engineered to reduce noise for applications such as plant rooms, sports arenas, hospitals and schools. 

The NAL300C is combines two of our NAL150 units to create a double banked unit with a blade pitch of 150mm and a frame depth of 300mm - whilst offering the acoustic and non-vision benefits of the double banked design. NAL300C louvres can be supplied as units suitable for fitting into formed openings or assembled onto a supporting structure. NAL units can either be singular in design or appear as a continuous installation. 

Where supporting steelwork is required, Naco are able to provide a complete solution, from drawings to supply and fixing of the steelwork and louvres or provide supply only.

The optional Naco CS (continuous sightline) construction combines the flexibility of modular construction with the aesthetic appeal of a continuous run in both horizontal and vertical planes.
