Fire and Acoustic Seals is one of the largest UK distributors of fire, smoke, and acoustic sealing systems for doors and windows.


Fire and Acoustic Seal (FAS) also manufactures a range of own-label fire door products listed within NBS. These have been specifically designed and tested with timber fire-rated doors and screens to provide guaranteed fire-stopping performance when used in these applications.


FAS fire-rated sealants including the revolutionary fire-rated expanding Fire Door FoamTM have been successfully tested in accordance with BS 476: Parts 20& 22:1987 and BS EN 1634-1 to assure their performance in the event of a fire as opposed to other, more general fire and smoke-stopping products on the market.


All products are independently third-party fire, smoke and acoustic tested to meet British and European Standards and building regulations.


Fire and Acoustic Seals also provides excellent customer service and technical support to customers including a next-day delivery service which helps contractors on tight timescales, and toolbox talks to ensure correct installation practices are met.


The company is part of the MBP Group of companies.
