Supabloc Supablocs combine low unit weight with high thermal insulation and acoustic performance, in strengths of 3.6, 4.2, 7.3 and 8.7 N/mm2. Durox Supabloc is recommended for general-purpose walling applications including inner leaves, solid external walls, internal partitions and walls below DPC. They are particularly suited for cavity and solid wall construction that require low U-values to be met. The use of Supabloc will minimise the amount of additional thermal insulation required, compared to the use of denser blocks. Durox Supabloc 4 is recommended for use in separating walls including...

Responsible Sourcing of Materials (Basic Building Eléments) - Mat 2 This aspect is intended to encourage the specification of responsibly sourced materials for the basic building elements such as external walls and floors. Responsible sourcing was an issue originally attributed to imported timber and the consequences including social conditions that arise from illegal logging. Although the focus has long been on timber, the Code now requires all basic materials to be considered. Credits are awarded based on the use of materials in key building elements as shown. Material Credits for Basic Building...

Meeting the Code with Durox The use of masonry built construction to satisfy the Code for Sustainable Homes is now commonplace. There is no single approach to design that will suit all house types. Tarmac have collaborated with builders on a number of schemes, providing design input and product advice, in determining a solution to meet the required Code level. Meeting the energy efficiency targets (Code 3 is 25% above 2006 Part L Standards) is probably the most challenging aspect to comply with. There will be site and cost considérations to consider when arriving at the most économie spécification....

design Safe handling Aircrete is an inherently lightweight material, which ensures that the majority of Durox aircrete blocks fall within the guidance (see Health and Safety Executive Construction Sheet 37) for single-person répétitive handling. Foundation blocks of 350mm x 310mm x 215mm size, as well as Foundation blocks with a 140mm bedding height are available which satisfy the nominal 20kg guidance for single-person handling. For guidance on the approximate weights of Durox blocks refer to the relevant product pages. Movement control Movement joints should be provided in accordance with BS...
