Zero Seal Systems Ltd are the UK specialists in the specification and supply of acoustic seals and thresholds for sound stopping doors. Our products have been used on prestigious projects like the International Convention Centre in Birmingham, Stansted Airport and Cambridge University.

To the best of our knowledge, no other specialist seal manufacturer can match the 52 STC rating achieved by our Soundtrap system. The system delivers this impressive decibel reduction by using four interacting components that form a continuous tight seal and comprises of: 

• Automatic door bottom - as the door closes the seal drops up to 25mm with a scissors action and seals the aperture between the door bottom and floor finish.
• Door threshold - incorporates a neoprene gasket to provide a compression seal and compensate for misalignment. (6mm projection thresholds available for wheelchair users)
• Head and jamb seal - gives continuous head and jamb protection with an adjustable neoprene gasket that seals against the full length of the door. A neoprene-encased magnet provides a second barrier.
• Head and jamb spring seal - self-adhesive metal spring seal that traps sound deadening air at the door head and jambs.

There are over 500 other products in the Zero range offering different degrees of sound control suitable for practically any situation from domestic to aircraft hangars and to suit thresholds, frames, meeting stiles and door bottoms.
