QuietStone is a noise reduction tile system developed by Sound Absorption UK Ltd which combines significant acoustic absorption capabilities with long life and aesthetic effects. The tile is specifically designed with air cavities which absorb unwanted frequencies of sound to create a more comfortable environment. The tiles or blocks are made of bonded natural material which creates the required air cavities which in turn produces advanced sound reduction properties.
Quiet Stone is a rigid, hard wearing, easily cleaned cladding material with the appearance and texture of pumice stone. Yet it offers sound absorbing properties better than many soft materials and, correctly installed, sound insulation equivalent to a solid brick wall.
Correctly installed Quiet Stone will not only give you the optimum acoustic balance within the studio but will also protect your recording from unwanted external noise. And of course sound penetrating out of the studio is dramatically reduced allowing the rest of your staff to work unhindered.
Quiet Stone has other advantages such as a two-hour fire rating and complete clean-ability. Quiet Stone can be vacuumed, scrubbed and washed with detergents or even bacteriocides without damage. Like any other normal wall it will take fixings for shelves, speakers, lights etc. Quiet Stone can be cut to shape around such things as light switches, sockets and other electrical fittings. Cabling can be hidden behind Quiet Stone and individual panels can be made detachable for easy access to fuse boxes and other electrical installations.
Quietstone Light Ceiling Tiles
Quiet Stone Light is a unique acoustic ceiling tile material, which compliments
our Quiet Stone wall cladding material giving excellent acoustic properties.
Quiet Stone as a generic material has been widely installed throughout
the UK.
Quiet Stone Light has been designed to fit into a standard suspended ceiling
and has excellent acoustic properties.
Where weight is a problem Quiet Stone Light can be fitted as a wall cladding. Quiet Stone & Quiet Stone Light can be easily cleaned. Trials carried out by leading suppliers of biocides used for sterilization have proved that Quiet Stone can be effectively disinfected of all common forms of bacteria without degradation. Quiet Stone & Quiet Stone Light have excellent fire resistant qualities and provide a two hour fire rating (BS476 part 8 1972).
