Our Airtec Brickettes are designed to offer brick-sized Airtec Concrete blocks for use as infill around doors and windows, to close cavities and maintain exact coursing height. These Aerated Coursing Bricks lessens the need for cutting down full blocks and help to maintain material continuity throughout the wall which preserves the wall's thermal, acoustic and air-tightness qualities.
Our Airtec Coursing Bricks are available in all Airtec product grades i.e XL, Standard, Seven and Party Wall with a range of thicknesses. Their face size is 215mm x 65mm, they are supplied banded, shrink-wrapped and on non-returnable wooden pallets.
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. Airtec blocks are available in Standard texture only, smooth faced but are not intended for fair-faced use due to
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.

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.
