Non-fire resisting doors in high rise tower blocks should be replaced immediately with doorsets that are certified for fire performance by a third-party certification authority, according to the UK Government.
This move, which follows the Grenfell Tower fire in west London, requires replacement doorsets to be certified by a UK Accreditation Service (UKAS) accredited, third-party certification authority to a standard providing at least 30 minutes’ fire resistance.
A letter from the Department of Communities and Local Government to council chief executives and housing associations on June 22 stated that doors that were deemed to be fire-resisting at the time of construction of the block would be satisfactory.
However, the letter instructed: โReplace any non-fire-resisting doors (such as non-fire-resisting uPVC doors) immediately with doorsets (doors and frames) that are third-party certified as providing at least 30 minutes fire resistance.โ
Secured by Design (SBD), the national police crime prevention initiative, has announced that it’s requiring doors that are either described as fire doors, or where fire performance is declared or implied, to have third-party certification for both security and fire performance.
To gain SBD Police Preferred Specification, manufacturers have been required to have third-party certification of security products such as doors and windows since 2005. Since Approved Document Q (Security) became effective in October 2015, security and fire, contained in the longer established Approved Document B, have carried equal weighting under the Building Regulations in England.
Third-party certification requires regular re-tests and production audits to ensure that product quality is assured and maintained over time and goes beyond the one-off testing required by the Building Regulations.
SBD reports that it has been in direct communication to advise its member companies most affected by the changes and have notified recognised certification bodies about SBDโs new requirement.
Mick Reynolds, SBD Senior Development Officer, said: โSBD has taken the pro-active decision for dual certification as an SBD requirement going forward. The DCLGโs letter is a radical change and seems to remove the ability for a door manufacturer to declare fire performance against a Global Fire Assessment or a one-off Fire Test Report.โ
