Acoustic Door Seal Kits
Zero International acoustic door seal kit components are the perfect solution for improving sound transmission loss on existing doors. Even the smallest gaps can reduce the effective STC rating of a door by 50%! The standard door seal kit includes an automatic door bottom, adjustable neoprene jamb seals, and threshold. These can be used for both wood and metal doors and are available in many styles and finishes, and can be custom cut to your specifications or cut in the field. In addition to standard door kits, we also have solutions for double doors requiring astragal seals, pocket and sliding doors, overhead doors, ADA Access doors, and more!
Zero International's advanced technology utilizes a concealed flat spring mechanism which activates when the door is closed, lowering a neoprene seal insert against the floor or saddle. A protruding, hinge-side "plunger" is compressed by the frame as the door closes to activate the spring. The seal then drops in a scissors-like motion from the hinge side, adjusting to the floor from a pivoting point. This motion ensures a smooth drop without drag for a tight, secure seal against the saddle or floor. The seal retracts automatically as the door is opened. Automatic door bottoms are available in mortised, semi-mortised, or flush mount option, clear anodized aluminum or dark bronze anodized finish, and are all rated for 5 million cycles.
ADJUSTABLE PERIMETER SEALS
Zero International's adjustable sealing system features a unique compress-o-matic design with a sound-absorbing neoprene rubber gasket that compresses to form a tight seal as the door is closed. The door jamb seals include adjusting screws to correct for irregular clearances between the door panel and jambs. Adjustable door jamb seals are available in clear anodized aluminum or dark bronze anodized finish.
Zero International's sound rated acoustical door thresholds feature a neoprene bulb fitted with a protruding rubber finger to help correct any misalignment in the door as it is closed. Used in combination with the automatic door bottoms they provide an excellent acoustical seal.
These thresholds can be used for both wood and metal doors and are available in aluminum and bronze finishes, as well as various styles and heights to fit your application.
