Product Overview
Thermalite Hi-Strength 7 blocks with a 440mm length, 215mm height, and 100mm width. These aircrete blocks are engineered for applications requiring enhanced load-bearing capabilities, offering a compressive strength of 7.3N/mm². The high-density formulation provides robust structural performance while maintaining thermal efficiency, making them a reliable choice for demanding residential and commercial masonry projects.
Their high-strength profile allows for use in multi-storey constructions, offices, and retail developments where structural integrity is critical. These blocks provide a solid foundation for various wall assemblies, combining durability with consistent performance in both internal and external environments.
The units are manufactured to precise standard dimensions, facilitating efficient laying and alignment. The product is designed with a specific density of 730kg/m³ and a standard width of 100mm.
Features & Benefits
- Compressive strength (7.3N/mm²): Provides the load-bearing capacity required for multi-storey residential, office, and retail developments.
- Thermal conductivity (λ = 0.18W/m·K): Delivers effective thermal insulation to reduce heat loss throughout the building envelope.
- Moisture resistance: Engineered to maintain durability and structural integrity in areas prone to damp conditions.
- Sustainable composition: Manufactured with 80% recycled content to support environmentally conscious building practices.
- High density (730kg/m³): Delivers superior load-bearing performance for heavy-load applications.
- Standard face dimensions (440mm x 215mm): Ensures consistent coursing and compatibility with standard masonry practices.
- Width (100mm): Designed for use in standard wall layouts, providing a balance of structural support and space efficiency in the 100mm width.
Applications
- Cavity walls external leaf below DPC: Suitable for supporting wall assemblies in below-ground conditions.
- Cavity walls external leaf above DPC: Provides structural strength and thermal protection for the external building envelope.
- Cavity walls inner leaf above DPC: Delivers load-bearing support for internal structures above the damp-proof course.
- Cavity walls inner leaf below DPC: Maintains structural integrity for foundation-level masonry requirements.
- Separating walls: Facilitates robust partition construction between units for acoustic and thermal performance.
Installation Guidance
- Surface preparation: Ensure foundations are level and free from debris to guarantee a stable base for the first course.
- Mortar application: Use thin-joint or traditional mortar to secure blocks, ensuring a strong bond and minimised cold bridging.
- Jointing: Stagger all vertical joints across subsequent courses to distribute loads effectively and prevent cracking.
- Alignment: Use appropriate levelling tools during installation to maintain consistent wall plumb and finish.
Compliance & Performance
- Compressive strength: Fully compliant with design requirements for high-load construction projects.
- Service class: Rated for both internal and external masonry applications above ground level.
- Finishing: Engineered with a textured surface profile that provides an excellent key for the application of standard renders and plasters.
- Pallet Charge: Orders requiring a pallet will incur a refundable pallet charge. Our customer service team will confirm if this applies to your order.
Delivery & Returns Information
Delivery charges vary by product category and order value. Items may ship from different suppliers and arrive separately, so delivery charges can be shown per part of your order at checkout.

How delivery works
We work with a nationwide network of trusted suppliers. Items in your basket may be supplied by different suppliers and delivered separately. Where this applies, you will see delivery charges shown at checkout for each part of your order. We always aim to group products from the same supplier to keep delivery costs as low as possible.
Delivery areas
Delivery charges apply to mainland UK, excluding: AB, CA, CF, DD, DG, EH, EX, FK, KA, KW, KY, IV, LA, LD, LL, ML, NP, PA, PH, PL, SA, SY, TR, TQ and TD.
If your address is in one of these areas, we will contact you before processing your order to confirm any additional costs. We do not currently offer delivery outside the UK mainland.
What to expect on delivery day
- Deliveries are typically kerbside.
- Please ensure someone is on-site to accept delivery. For heavier items, help with offloading may be required.
- Many building materials arrive on large vehicles. If access is restricted, a specialist vehicle such as a HIAB may be required and could incur an additional charge.
Why delivery can cost more than typical parcel delivery
Building materials often travel on larger vehicles and usually carry fewer drops per run than parcel networks. That is why delivery charges can be higher than standard e-commerce shipping.
Returns
Returns depend on what you have bought and whether there is anything wrong with it. For full details on eligibility, timeframes, and exclusions, please see our full policy.
