CSR Hebel Introduction

CSR Panel Systems is a division of CSR Building Products Limited, one of Australia’s leading building products companies.

CSR Panel Systems manufactures Hebel® Autoclaved Aerated Concrete (AAC). The AAC in Hebel® products is manufactured from sand, lime and cement to which a gas-forming agent
is added. The liberated gas expands the mixture, forming extremely small, finely dispersed air pockets, resulting in lightweight aerated concrete.

CSR Panel Systems has manufactured Hebel® products that have won wide acceptance as innovative and environmentally preferable building materials. This is due to their lightweight nature, excellent thermal, fire and acoustic properties and design versatility. These inherent properties of Hebel® products help achieve quick and cost efficient construction practices
as well as providing for comfortable operating environments inside the buildings all year round.

Build a premium home with Hebel PowerBlock.

Hebel® PowerBlocks are large AAC Blocks with a standard face dimension of 600mmx200mm, laid in much the same way as bricks but using Hebel® Adhesive to form
a monolithic structure. Typically, external walls use a single skin of 250mm thick blocks while internal, non-loadbearing walls use 100mm thick blocks. Hebel’s tight manufacturing tolerances deliver beautifully flat, true surfaces that are easily rendered and painted.

Walls built with Hebel® PowerBlock are strong and durable, providing the security of solid masonry coupled with exceptional thermal and acoustic insulation properties. With over three
times the thermal resistance of double brick, Hebel® PowerBlocks exceed the Building Code of Australia (BCA) for energy efficiency regulations for zones 1,2, 3 and 5 without the need for additional bulk insulation.

Hebel® PowerBlocks are non combustible and can achieve an Fire Resistance Level (FRL) of up to 240/240/240.

For detached houses, this is well above the requirements for building right up to the boundary line and making Hebel® an ideal choice for bushfire prone areas.

Compared to traditional double brick construction, Hebel® PowerBlock™ walls can be laid much faster, saving building time and costs. Building with Hebel Blocks may create more internal floor area for the same building dimensions. Hebel® Lintels can be used over windows, doors and garage door openings. Hebel® also supplies sill blocks for under windows to complement the overall look of your home.

CSR Hebel Energy Efficiency

Table 3.1 shows a number of different external wall configurations and identifies which satisfy the BCA requirement for Climate Zones 1 to 8. Table 3.2 lists the component R-Values used as a basis for Table 3.1. For more information on Hebel and energy efficiency refer to Section 3 and Appendix C and D of the Hebel Technical Manual.
