Aerated Concrete Blocks

Suitable for both load bearing and non load bearing applications, our stock includes standard sizes to match common brick coursing. 

Key Details About Our Aerated Blocks

At Joseph Parr Alco, you will find aerated concrete blocks that deliver U-values that meet Part L building regulations without additional insulation in many cavity wall configurations. 

Aerated blocks have a cellular structure that effectively traps air pockets, reducing thermal bridging and improving energy efficiency across the building envelope. Our standard aerated blocks come in 100mm, 140mm, and 215mm widths to suit inner leaf construction, separating walls, and single skin applications where lightweight masonry reduces foundation loads.

Tradespeople value aerated lightweight concrete blocks for their ease of handling and cutting. They are much lighter blocks than denseconcrete blocks, speeding up installation and reducing physical strain during laying. You can cut aerated blocks with a handsaw or masonry blade, allowing precise adjustments on site without specialist equipment. 

This workability makes them practical for forming openings, chasing services, and creating non standard details.

Our aerated block range suits both rendered and drylining finishes. The smooth surface accepts plaster directly, while the dimensional accuracy maintains consistent coursing heights when used alongside facing brickwork.
