Building blocks

An inherently sustainable and versatile building material

The workhorse of the construction industry, aircrete and aggregate building blocks are an essential component in the creation of a safe and sustainable built environment.

Robust and durable, they form the foundations, floors and walls of almost all kinds of buildings. Their excellent thermal and sound insulating properties are key to meeting current Building Regulations, including Part L, and the Code for Sustainable Homes.

Usually concealed within the fabric of a building, or visible only in more functional buildings such as sports halls or factories, blocks can also be used to create an architectural statement, either left bare or painted.
