Flame Retardant (FR) chemical treatments for timber work by reducing its ignitability, slowing down the surface spread of flame and, as a result, reducing the heat released. This allows more time for escape in a fire situation.

These effects can improve the material’s ‘reaction to fire’ classification significantly.

Case studies

The original Victorian pier was built in 1872, rebuilt in 1922 and finally destroyed by fire in 2010. The architect dRMM became involved when Hasting Pier Charity took over the derelict structure and set up a design competition which was won by the practice.

The Stonebridge Hillside Hub is a key scheme in the continuing regeneration of the Stonebridge Estate in West London.
