(4.8 stars) • 10 reviews
Description:

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 BBA certified, ISO 9001 Quality, ISO 14001 Environmentally and BES 6001 Responsible Sourcing certified.

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.
