Acoustic Door Louvres

Sound Block Louvre System

An acoustic louvre is somewhat of a contradiction in terms; a louvre is designed to allow the passage of air through a door, but at the same time it will permit the passage of sound. The SBLS is designed to reduce the amount of sound passing through the door whilst still allowing air to flow. In acoustic tests, our 300mm deep SBLS louvre has achieved a sound reduction of Rw18dB, and the 600mm deep SBLS louvre Rw32dB. Louvre panels to any sizes are available. Both solid, louvred and glazed over panels and side panels can be manufactured to suit individual customer requirements.

*Magnelis steel is offered as an alternative. Please enquire.
