Forterra

Forterra is one of the UK's leading manufacturers of clay and concrete building products, headquartered in Northampton, with brands including London Brick, Butterley, Ecostock, Thermalite and Bison Precast.

Although it also makes blocks and precast products, its brick activity includes Fletton, extruded, soft-mud and special-shape bricks for housing and restoration.

When specifying its bricks, distinguish the plant and firing type, and confirm availability and colour, especially for historic brick replacements.
