Airtec Standard

3.6 N/mm² AERATED CONCRETE WALL BLOCKS
(4.8 stars) • 10 reviews
Description:

Airtec Standard are the perfect all-round residential aerated concrete blocks giving you a combination of medium strength and high thermal performance in one block.

These concrete wall blocks are unique in combining a thermal conductivity of only 0.11 W/mK, with a compressive strength of 3.6 N/mm² to allow flexible design for single and multi-storey construction. All Airtec products are BBA certified, ISO 9001 Quality, ISO 14001 Environmentally and BES 6001 Responsible Sourcing certified.

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 finish only, providing a plain-faced, smooth, cellular texture which is a suitable background for accepting renders and plasters. Airtec blocks are not intended for paint-grade or fair-faced applications.
