Sound Seal

Parameter Seals

These products seal the gap between the door and frame or on meeting stiles of double doors.

The seal is squeezed between the door and the stop when the door is closed, thus compensating for warped or unevenly hung doors. Tested in accordance with BS EN ISO 140-3: 1995
