Key Information

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.

Hardware

Door leaves are hung from 4no stainless steel hinges for smooth operation and optimum weather resistance. Security dog bolts secure the leaf into the frame if the hinges are attacked. Additional hardware includes a range of locks, latches, lever handles, panic hardware, closers and stays. On double doors, lever-action flush bolts can be installed within the leading edge of the inactive door leaf.

Finish

Available in any RAL or BS standard or marine-grade powder-coat finishes.
