In order for doors to open and close effectively, gaps around the sides of a door leaf are essential.

Unfortunately, these gaps can naturally allow sound to pass through and therefore sealing these gaps is critical in reducing the amount of sound entering or leaving a room.

Approved Document E to the Building Regulations provides specific acoustic performance requirements for doors in certain buildings; including schools, care homes and hotels. Exitex have designed and developed a range of effective seal solutions to specifically address acoustic issues and have a tested and proven system for both 30 and 60 minute fire rated doors, non-fire doors, and double-leaf doors.

For fire rated doors, our combined smoke and fire seals provide acoustic protection. For non-fire rated doors, where intumescent protection is not required, we have a range of seals including our Ramflex Acoustic Perimeter Seal. All of these seals are designed to be fitted across the top and vertical sides of the door.

Sealing the bottom of the door is also vital, for this we have a wide choice of Dropdown Seals from our Concealex range, which all have fully tested acoustic performance.
