Acoustic Door Louvre

SBLS SOUND BLOCK LOUVRE SYSTEM – NON VISION

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, the SBLS has achieved a Rw of 16. It incorporates an SB Sound Block which is 14mm thick and manufactured from sound deadening material. This is sandwiched between a FDLS louvre one side of the door and a DRDL louvre on the other.
