EWI & render

Our external wall insulation systems wrap homes in a new insulated skin, cutting heat loss through the walls and refreshing the look of whole streets.

The system

Insulation boards are fixed to the wall, reinforced with mesh and base coat, and finished in render or brick-slip. We adapt sills, pipework and services so the new wall line looks right.

The benefits

Lower heat loss, warmer internal walls, less condensation and mould, and a durable weatherproof finish. Residents stay at home while we work.
