A CS Cavity Slider is a functional and efficient alternative to conventional surface sliding or hinged doors. Our cavity slider units enable a door to slide inside the wall leaving the floor and wall space on both sides clear and unobstructed.
The SoundStop accepts standard and non-standard sized doors that have a reduced sound transmission rating, these can be removed even after wall linings are fitted. The type of door fitted is dependant on the STC (Sound Transmission Class) required. An STC rating up to 43 has been achieved with our accoustically rated products. Doors must be supplied by CS Cavity Sliders to be an accredited sound rated cavity slider.
Locations where SoundStop is ideal include board/meeting rooms, radio stations, recording studios, home media rooms, hospitals and medical centres.
