Hush-Fill 60 is a 2–10 mm granular mineral filler, packed in sealed polythene tubes, specifically designed to meet the required density of 80 kgs/m² at the 60 mm regulation depth specified within UK Building Regulations for sound insulation between timber floor joists. It is a most effective means of reducing the airborne sound transmission between separating floors within a timber construction and has been expressly packaged to enable easy and accurate installation.
Joist loadings must always be checked by a structural engineer prior to specification or use.
Hush-Fill 60 must never be installed directly onto a plasterboard or lath and plaster ceiling, supporting shelves of 9 mm plywood screwed to the underside of the joists or on a shelf constructed between the joists should be provided. Hush-Fill 60 tubes weigh approximately 25 kg each and care must be taken when manually handling and lifting. 3.2 tubes cover 1 m² at 60 mm depth.
