A new red brick colour has been created for the Saint-Gobain Weber External Wall Insulation (EWI) system chosen by Rotherham Metropolitan Borough Council (RMBC) for its property upgrade programme.

The weber.therm XM EWI system, finished with weber.rend RB Render Brick in the new Georgian Red colour, accurately matches the established red brick Georgian properties in the area, a requirement of RMBC’s senior building surveyor.

The 88 properties being renovated – built in the 1930s – were identified as hard to treat, some with solid walls and some with narrow cavities of varied dimensions. To achieve a target u-value of 0.28W/m²K from 1.48W/m²K, 80mm of expanded polystyrene (EPS) insulation was fixed to the outer walls as part of the weber.therm XM system and finished with the weber.rend RB Render Brick finish, a combination of two coloured mortars used together to create the brick effect finish.
