DUROX Supabloc

Aerated Concrete Blocks – DUROX Supabloc

Overview

Durox is a modern construction material, whose versatility, light weight, thermal and acoustic properties make it the ideal solution for a wide variety of applications in all types of building.

Durox can be used below ground in foundation walls and in all types of internal and external walls. It provides many benefits for specifiers and contractors making it the natural choice where blockwork is specified.

Durox Supabloc combines low unit weight with high thermal insulation and acoustic performance in strengths of 3.6, 4.2, 7.3 and 8.7N/mm2 .

Where can DUROX Supabloc be used?

General purpose walling

Durox Supabloc is recommended for general-purpose walling applications including inner leaves, solid external walls, internal partitions, and solid 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.

Fire resistance

Durox blocks provide excellent periods of fire resistance which can satisfy Building Regulations and other imposed requirements e.g. those by insurers. All Durox products conform to a fire rating of Class A1 to BS EN 13501-1: 2002.

Sound separating walls

Durox Supabloc 4, 7, and 8 are recommended for use in sound separating walls including those conforming to Robust Details E-WM-6, E-WM-15, E-WM-23, E-WM-24 and E-WM-30.

Loadbearing walls

Durox Supabloc 7 and 8 are suitable for more demanding loadbearing applications, whilst retaining the characteristing low unit weight of aircrete.

Supabloc 7 is typically used in the ground floor of 3 storey housing in accordance with Approved Document A.
