Product Overview
These aircrete blocks are engineered for versatile applications in residential and commercial construction, offering a compressive strength of 3.6N/mm². Compared to dense concrete blocks, these units provide significantly higher thermal resistance and a lower mass, making them an effective solution for meeting Part L building regulations without the need for additional insulation thickness in certain configurations. The balanced formulation provides reliable structural performance alongside thermal efficiency, making them a practical choice for a wide range of masonry wall assemblies.
Their performance profile allows for use in various wall configurations, including cavity wall leaves and internal partitions, where structural load requirements are moderate. These blocks provide a consistent, moisture-resistant building medium that maintains stability in both internal and external environments. Unlike dense aggregate blocks, the cellular structure of aircrete reduces thermal bridging at junctions, though it is suited for lighter load-bearing requirements. The units are manufactured to precise standard dimensions, facilitating efficient laying and alignment. The product is designed with a specific density of 600kg/m³ and a standard width of 100mm.
Features & Benefits
- Compressive strength (3.6N/mm²): Provides the load-bearing capacity required for low-rise structural and partition walling.
- Thermal conductivity (λ = 0.15W/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.
- Lightweight aircrete (600kg/m³): Improves handling efficiency and supports faster build times on-site.
- 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.
-
Thermal Bridging Reduction: Aircrete's lower thermal conductivity compared to dense concrete blocks makes it the preferred choice at junctions where thermal bridging commonly occurs. window reveals, lintels, and wall-floor junctions.
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: Rated at 3.6N/mm², fully compliant with BS EN 771-4 for load-bearing applications in low-rise construction.
- Thermal conductivity: Achieves a lambda (λ) value of 0.15 W/m.K, significantly outperforming dense concrete and aiding in carbon reduction.
- Fire rating: Classified as Euroclass A1 non-combustible, providing excellent fire resistance in both load-bearing and non-load-bearing walls.
- Part L Regulation compliance: Contributes directly to meeting the fabric energy efficiency standards of Approved Document L (England and Wales) by reducing thermal bridging at junctions.
- Important note: To maintain full compliance with Part L building regulations, ensure all junctions are detailed in accordance with Accredited Construction Details to prevent significant heat loss through thermal bridges.
- Pallet Charge: Orders requiring a pallet will incur a refundable pallet charge. Our customer service team will confirm if this applies to your order.
