350MM THERMALITE TRENCH BLOCK 440 × 215 – 3.6N
Thermalite Aircrete Trenchblocks 3.6N are lightweight, aerated concrete blocks engineered for efficient below-ground construction, particularly foundation walls. Designed to combine structural performance with ease of handling, they provide a modern solution for fast and reliable groundworks.
Product Features / Specifications
Thermalite Trench Blocks offer a faster, more thermally efficient, and labour-saving alternative to traditional foundation construction methods such as cavity walls filled with concrete or the use of dense engineering bricks. Their aircrete composition improves thermal performance while reducing manual handling strain on site.
Product Benefits
The precision-manufactured, interlocking design allows for rapid alignment during installation and removes the need for mortar in the vertical joints (perpendiculars), significantly speeding up build time. By eliminating the requirement for concrete infill in cavity walls and reducing overall mortar usage, these trench blocks help lower material costs, minimise waste, and streamline foundation construction without compromising strength or durability.
Applications and Versatility
- Below-ground foundation walls
- Trench fill and foundation blockwork
- Residential new builds and extensions
- Low-rise commercial and industrial projects
