Perimeter Seals

Perimeter seals are an essential part to an effective acoustic door seal solution as they effectively fill the natural gap created between door leaf and frame in a doorset. This range covers both retro and rout in versions to suit almost every requirement. The seals work by filling the air gaps that create sound leaks around the head and jambs of the doorset, this also stops smoke, light, dust…etc.
