Aerated autoclaved block

These lightweight concrete blocks are 80% air, which explains the name “aerated.” The material can be easily shaped and allows for the use of nails and screws. But it’s not as strong as some denser concrete options, so it’s not the best load-bearing concrete and often needs to be reinforced. You’ll also want to seal it with a protective finish to avoid deterioration when exposed to the elements.

These blocks are white to light gray and can be customized for use in sidewalls, partition walls, and other types of wall construction, as well as for steel pillars and infill panels. They’re available in blocks, panels, and specialty shapes such as lintel blocks and U-shaped bond beam blocks, both of which are available in different thicknesses.
