The scheme has grown from 133 members at the end of 2005 to 172, while several more companies are currently undertaking the certification process.

“The scheme is growing steadily because companies are recognising the importance of obtaining a guarantee for the product they are using through certification and regular auditing,” said scheme manager Scott Marshall.

Newly certificated fire door producers include Prime Door Manufacturers, Corinthian Industries (Jeld-Wen’s Malaysian subsidiary) and Doorworks Ltd, while six companies have become licensed convertors of fire doors, which can involve adding frames or vision panels to products.

The number of BWF Approved Fire Door Centres is also growing, following the successful training of several merchants’ staff.

Staff at 30 of Wolseley UK’s Build Center branches have completed Certifire scheme training, while Howarth Timber and Building Supplies and Alsford Timber have each competed training at two new branches, bringing their number of fire door centres to 22 and 19 respectively. Gibbs and Dandy has increased its commitment to five branches.
