Clark Door has built a worldwide reputation for supplying high quality, reliable acoustic doors to the entertainment industry, film studios, music venues, theatres, cultural centres and many other industries requiring specialist, sound insulating and acoustic fire rated doors.
Manufactured in the UK to ISO 9001:2015 and with over 40 years of independent acoustic test data Clark Door has built a worldwide reputation for high quality, reliable acoustic doors. Working together with architects, engineers, theatre consultants and acousticians the Clark Door Design Team provide individually designed acoustic doors to the most challenging customer’s specifications.
Large size high performance acoustic doors often have a large mass which will impose significant loads onto the building structure. By consulting us early in the design process this loading can often be incorporated into the building without the need for the later addition of expensive secondary supporting steelwork.
With over 40 years of independent acoustic test data, including laboratory tests to ISO717 and on site acoustic tests, we manufacture a wide range of acoustic door types with required sound insulation. Available with up to Rw 60dB on a single acoustic door and a higher attenuation with combination acoustic doors. Product and acoustic data sheets are available for architects and acousticians upon request. Please contact us for further information about our acoustic doors.
Acoustic Fire Doors
Large acoustic doors up to Rw 60dB can be fire rated to EI 120 / BS EN 1634-1, eliminating the need for separate fire shutters. The doors feature the Clark Digital Controller (CDC), an encoder positioning system to ensure precise seal compression in the closed position, with automatic reset in the event of power failure. The CDC enables easy connection to the fire protection system, normally through the assured supply: when activated it provides a signal to the door closing circuit which overrides all other signals. An assured power supply is required but optional battery backup or manual disconnect device and procedure can be provided if necessary.
