A low-carbon approach

We favour low-footprint materials: low-carbon masonry cement and insulating terracotta brick, alongside lime and stone.

−80%
less CO₂ possible with a low-carbon masonry cement, compared with a traditional cement
R = 3.25
m²·K/W: thermal resistance of an insulating terracotta brick (37 cm)
A1
fire rating of the terracotta brick: non-combustible, no VOCs
