LARGE AERATED CONCRETE BLOCKS FOR FLOORING

Airtec Large Aerated Concrete Floor Blocks are designed for use in beam and block floors to provide significantly improved thermal insulation of ground floors and quick, easy installation. They can also be used as Wall Blocks, see Large Aerated Concrete Wall Blocks for more information.

These lightweight concrete blocks for flooring can be laid in either the 620mm width or the 430mm width, offering a choice of reinforced inverted T-beam centre spacings of 705mm and 515mm respectively.

An Airtec floor provides an excellent substrate for application of screed and floating floor finishes. These aerated concrete blocks can be easily cut, bored and shaped where required for simple installation around services and are suitable for use with under-floor heating systems.

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, these lightweight large concrete blocks offer the very best possible dimensional tolerance category of 'Thin Layer Mortar B' (TLMB) but are perfectly suitable for conventional 10mm mortar joint construction.

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.

The block and texture images are intended for indicative purposes only and actual textures and shades may vary between manufacturing locations. Please contact your regional sales office for further information and sample blocks. We advise the construction of sample panels on site as masonry appearance cannot be appreciated from individual blocks.

    • A range of a wagon sizes are available, with or without pallets. Ring your local Sales office for further details.
    • Block weight is at the equilibrium moisture content of 3% by weight
    • Pack weight allows for maximum moisture content when packed, actual delivered weight will be less
