The Forterra Thermalite Hi-Strength 7 Aircrete Block is designed for construction professionals and builders seeking robust structural performance with enhanced thermal efficiency. Its primary benefit is combining high load-bearing capacity with superior insulation properties, reducing energy consumption and CO2 emissions. A potential consideration is its specialized application requiring specific structural knowledge for optimal use. This 100mm block offers a lightweight, durable, and fire-resistant solution for walls, floors, and below-ground constructions.

The compressive strength is 7.3N/mm².
Yes, they are suitable for below-ground constructions requiring enhanced structural support, provided appropriate damp-proofing and drainage measures are in place.
Yes, their high compressive strength makes them ideal for load-bearing walls, floors, and other structural elements.
Their closed micro-cellular structure contains trapped air pockets, which act as natural insulators, reducing heat transfer.
The dimensions are 440mm (length) x 215mm (height) x 100mm (width).
Standard masonry mortar can be used, but it's advisable to follow manufacturer recommendations and ensure suitability for aircrete materials.
Yes, they help achieve U-value targets and reduce CO2 emissions over the building's operational life.
Handle blocks with care. Use appropriate cutting tools (e.g., masonry saw with dust extraction) and support blocks adequately during cutting. Ensure proper storage to prevent damage.
Ensure the block surface is clean and dry before applying mortar. Use the correct mortar mix as recommended for aircrete blocks. For below-ground applications, ensure appropriate damp-proof coursing and drainage.
While the blocks offer good insulation, consult the manufacturer's thermal performance data and consider additional insulation or construction details as required by building regulations and specific project designs.
Setup: These blocks are designed to be laid using standard masonry mortar. Ensure a level and prepared foundation or supporting structure before commencing. For structural applications, always follow project-specific engineering designs and building regulations. Ensure correct alignment and bonding patterns for load-bearing walls.
Compatibility: The Thermalite Hi-Strength 7 Aircrete Block is compatible with most standard building materials, including conventional mortars, renders, plasters, and fixings. It can be integrated into timber frame, steel frame, and traditional masonry constructions. Ensure any direct-to-block finishes are suitable for aircrete.
Care: Store blocks on a level surface, preferably on pallets, away from prolonged direct moisture or extreme weather conditions. Protect from damage during transport and handling. Once installed, the blocks require minimal ongoing care, with maintenance typically focused on the applied finishes (render, plaster, etc.).
