{"product_id":"100mm-thermalite-aircrete-3-6n-shield-block","title":"100mm Thermalite Aircrete 3.6N Shield Block","description":"\u003ch2\u003eProduct Overview\u003c\/h2\u003e\u003cp\u003eThese 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.\u003c\/p\u003e\u003cp\u003e\u003cbr\u003eTheir 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.\u003c\/p\u003e\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\u003ch2\u003eFeatures \u0026amp; Benefits\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompressive strength (3.6N\/mm²)\u003c\/strong\u003e: Provides the load-bearing capacity required for low-rise structural and partition walling. \u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThermal conductivity (λ = 0.15W\/m·K)\u003c\/strong\u003e: Delivers effective thermal insulation to reduce heat loss throughout the building envelope. \u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMoisture resistance\u003c\/strong\u003e: Engineered to maintain durability and structural integrity in areas prone to damp conditions. \u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSustainable composition\u003c\/strong\u003e: Manufactured with 80% recycled content to support environmentally conscious building practices. \u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLightweight aircrete (600kg\/m³)\u003c\/strong\u003e: Improves handling efficiency and supports faster build times on-site. \u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandard face dimensions (440mm x 215mm)\u003c\/strong\u003e: Ensures consistent coursing and compatibility with standard masonry practices. \u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth (100mm)\u003c\/strong\u003e: Designed for use in standard wall layouts, providing a balance of structural support and space efficiency in the 100mm width.\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\u003ch2\u003eApplications\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCavity walls external leaf below DPC\u003c\/strong\u003e: Suitable for supporting wall assemblies in below-ground conditions.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCavity walls external leaf above DPC\u003c\/strong\u003e: Provides structural strength and thermal protection for the external building envelope. \u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCavity walls inner leaf above DPC\u003c\/strong\u003e: Delivers load-bearing support for internal structures above the damp-proof course. \u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCavity walls inner leaf below DPC\u003c\/strong\u003e: Maintains structural integrity for foundation-level masonry requirements. \u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeparating walls\u003c\/strong\u003e: Facilitates robust partition construction between units for acoustic and thermal performance.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThermal Bridging Reduction: \u003c\/strong\u003eAircrete'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.\u003cbr\u003e\u003cbr\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Guidance\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSurface preparation\u003c\/strong\u003e: Ensure foundations are level and free from debris to guarantee a stable base for the first course. \u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMortar application\u003c\/strong\u003e: Use thin-joint or traditional mortar to secure blocks, ensuring a strong bond and minimised cold bridging. \u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eJointing\u003c\/strong\u003e: Stagger all vertical joints across subsequent courses to distribute loads effectively and prevent cracking. \u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAlignment\u003c\/strong\u003e: Use appropriate levelling tools during installation to maintain consistent wall plumb and finish.\u003cbr\u003e\u003cbr\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eCompliance \u0026amp;
