Norsound recommend the use of an approved doorset manufacturer ensuring seals are fitted in accordance to the Norsound test schedule.

Norsound acoustic seals are designed and developed to help both specifier and end user alike comply to current building regulations such as Approved Document E and Approved Document M. Our acoustic seals can be used on a standard fire door to give decibel reductions in excess of those stipulated in both document E and building bulletin 93 (BB93).
