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.
Galvanised steel grey primed – other finishes available to order, including Grade 304 and Grade 316 Stainless Steel.
16 Rw. Please note this product should be fitted in the factory with the door in the horizontal position.
Please note that these product properties are not a replacement for the manufacturer's literature and it is always recommended that Zero Seal Systems is consulted before specifying.
