Lightweight Aerated Blocks

At Mitcham Builders Merchants, we stock a wide range of aerated blocks ideal for both domestic and commercial construction projects. Known for their excellent thermal insulation and lightweight properties, aerated concrete blocks are a popular choice for everything from internal partitions to external walls.

These blocks—often referred to as Thermalite blocks—are easy to cut, handle and lay, making them perfect for speeding up build times while reducing manual handling strain. Despite their low weight, aerated blocks offer impressive compressive strength, along with strong fire resistance and acoustic insulation.

Whether you're building extensions, garden walls or full housing developments, aerated block options at Mitcham Builders Merchants come in various sizes and specifications to suit your project needs. Our experienced team is always available to provide advice on quantities, load-bearing suitability, and installation tips.
