Airtec Aerated Concrete Blocks

Airtec Standard

3.6 N/mm² AERATED CONCRETE WALL BLOCKS

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 ISO 9001 Quality and ISO 14001 Environmentally certified and with the highest possible BES 6001 Responsible Sourcing rating of ‘Excellent’.

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. These Aerated Blocks are smooth faced but are not intended for fair-faced use due to the natural air bubbles on the block surface.

Our Airtec Concrete blocks are available in ‘Standard’ texture finish providing a plain-faced, smooth, cellular texture which is a suitable background for accepting renders and plasters.

In common with all aerated concrete in the UK, the surfaces of the building blocks may contain a random number of larger natural air bubbles/cells on the block surface due to an unavoidable consequence of the manufacturing process. These large cells are perfectly normal and are not a defect and do not detract from performance in any way. Although the blocks can be painted, we cannot guarantee that the surfaces will not contain some of these larger cells and we therefore do not recommend using Airtec for paint-grade or fair-faced applications.
