MHCLG

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.
