Chris Flaherty – Technical Director at Winkhaus UK and Jon Cole – Chief Operating Officer at Secured by Design explain the importance of smoke resistance testing and how they have worked together to close a potential gap in the standards.

The 2019 MHCLG guideline for fire doors identified 3 critical features of required tested performance FIRE, SMOKE and ENHANCED SECURITY. Equally, the MHCLG guideline clearly states that these critical performances should be audited by 3rd Party independent audits / Certification.

Winkhaus FireFrame® composite fire door sets are the first fire door solutions to attain the Q Mark 3rd party audit / Certification for all three critical performance requirements. By the summer 2022 this will be the minimum technical requirement for all Secured by Design accredited door sets.

The internet is awash with manufacturers, installers and ‘experts’ citing different test standards and accreditations.  Scott Francis, Technical Manager at Bowater Doors unpicks this information and explains what you should look for when choosing a composite fire door.


Look for the latest standard - BS EN 1634
BS EN 1634 is the latest standard for fire resistance and smoke control and is accepted in Approved Document B, the fire safety element of the Building Regulations in England.
It’s a far more demanding test in comparison to the old BS 476 standard. This is particularly in reference to the requirement to expose both sides of the door to the fire combined with the increased level of pressure and heat in the furnace.  We made the decision to test our doors to the limits with regards to safety and security to ensure we are offering the best composite fire door on the market.

This highlights broader potential failings within the industry and the Government is taking immediate action to address this.

MHCLG began investigating the fire door industry after it was found that a glazed, composite fire door from Grenfell Tower manufactured by Manse Masterdor failed a 30 minute fire resistance test after approximately 15 minutes. Issues were subsequently identified with doors produced by Masterdor Limited (the successor business to Manse Masterdor). Investigations have continued and in the last few days doors from 3 additional manufacturers have failed fire resistance testing when tested on both sides.
