SEALz® Acoustic Seal helps to reduce the amount of sound that passes through a room and it is one of the most common and important applications.
Acoustic seals provide an excellent barrier to airborne sound and help ensure that the acoustic attenuation provided by a doorset (the frame and doorleaf along with the seal) is, in many cases, equivalent to the wall or partition into which it is installed.
§Astragal – This meeting stile seal is necessary for double doors. It seals the gap between the two doors and is used when only one door leaf is active. This seal is used on plain and rebated meeting stiles.
