Fire door data collection
Note to building owners/responsible persons concerning issues associated with Manse Masterdor and Masterdor Limited doors:
The Ministry of Housing, Communities, and Local Government has been undertaking an investigation into flat entrance 30 minute fire doors supplied by Manse Masterdor, a company that ceased trading in 2014.
During the Grenfell Tower inquiry, a fire door was taken by the Metropolitan Police and tested to determine its fire resistance.  As has previously been reported, an issue was identified with a fire door installed at Grenfell Tower [previous statements from the Government are available]. This door – manufactured by Manse Masterdor – was marketed as meeting the 30-minute resistance standard, but failed the test after approximately 15 minutes. Issues were subsequently identified with doors produced by Masterdor Limited (the successor business to Manse Masterdor).
The Secretary of State for Housing, Communities, and Local Government made a written statement to Parliament informing them the Independent Expert Panel on Building Safety has sufficient evidence to conclude that flat entrance doors supplied by Manse Masterdor do not consistently meet the 30 minute fire resistance standard they were marketed as providing.
The Expert Panel – supported by the National Fire Chiefs Council – has clarified that while the risk to public safety remains low, those buildings affected by this issue need to review their fire risk assessment to take into account this new information. This assessment should also consider how quickly these doors should be replaced.
The Ministry of Housing, Communities and Local Government has asked that the responsible person provide details of these buildings where the Manse Masterdor or Masterdor Limited doors have been installed. Please note, this investigation only relates to the above two companies. If you have a question related to another type of door, please direct this query to the Ministry at: FireDoorTeam@communities.gov.uk. Further updates on testing of doors from other suppliers is also available on the Ministry’s website.
