Airtec XL - Blocks
by Thomas Armstrong Group
Airtec XL is our lowest weight and thermally best performing block in our entire range possessing a themal conductivity value of only 0.09 W/mK - unique and unrivalled by any other aerated block with a strength of 2.9 N/mm2.
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.
