Transport for London (TfL) has awarded fire-retardant treatment firm Halt NFR with a contract to become approved supplier of fire-retardant timber.

The contract will see HALT supplying all of the fire-retardant timber used in construction work across the London Underground.

Belfast-based HALT uses pressure impregnation to reduce the flammability of timber and prevent the spread of flames. The treatment itself includes impregnating timber using BurnBlock, which prevents oxygen from reaching the treated timber. 

HALT, which operates from a £1.2m purpose-built facility in Belfast, has also won a contract to supply its specially treated timber to the UK’s HS2 project, as well as an agreement to treat internal wall linings in Dublin Castle for the Office of Public Works (OPW).

“The construction industry is currently adapting to the largest set of building regulation changes in over a decade,” said Ronan Higham, managing director at HALT.

“A critical part of this has been adapting to new rules, regulations and ways of working to enhance the performance of building materials in the event of a fire.”

Mr Higham said HALT had spent the last few years developing a solution for architects, main contractors and clients, that would allow the timber used in their projects to withstand extreme heat to allow users, occupants, and residents to escape in the event of a fire. 

HALT is part of the Pure Fitout Group which has completed projects across several prestigious London locations including the full refurbishment and fitout of Claridge’s Spa, The Adria in South Kensington, and the brand new Bellazul in Marylebone.
