Airtec Seven

Airtec Seven blocks possess high loadbearing capacity and excellent thermal performance. Perfect for higher-rise applications where thermal insulation and durability are required.

In common with all other Airtec blocks, they boast the very best possible dimensional tolerance category of 'Thin Layer Mortar B' (TLMB) but are perfectly suitable for conventional 10mm mortar joint construction. Airtec blocks are available in Standard texture only, Smooth faced but are not intended for fair-faced use due to the natural air bubbles on the block surface.
