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.

CSR Hebel PowerBlock Handling

Manual Handling

To minimise the possibility of manual handling injuries, Hebel suggests the following:

  • Use mechanical aids, such as trolleys, forklifts, cranes and levers, or team lifting to move Hebel.
  • Keep the work place clean to reduce the risk of slips, trips and falls, which can cause injury.
  • Plan the sequence of installation to minimise panel movements and avoid awkward lifts.
  • Good lifting techniques to be adopted to minimise the risk of injury.

Mechanically Assisted Handling

Moving and handling Hebel Floor panels and Hebel Lintels should be done using mechanical aids such us forklifts, cranes and special panel lifting trolleys. Different panel lift attachments are available for installing panels. For purchasing or hire of these devices please contact CSR Panel Systems.

Health, Safety & Personal Protective Equipment (PPE)

Hebel AAC products are cement-based, which may irritate the skin, resulting in itching and occasionally a red rash. The wearing of gloves and suitable clothing to reduce abrasion and irritation of the skin is recommended when handling Hebel AAC products.

Approved respirators (AS/NZS1715 and AS/NZ1716) and eye protection (AS1336) should be worn at all times when cutting and chasing. Refer to the Hebel Material Safety Data Sheets (MSDS).

For further information contact CSR Panel Systems or visit the website: hebelaustraliacom.au.

Cutting

The use of power tools when cutting masonry products may cause dust, which contains respirable crystalline silica, with the potential to cause bronchitis, silicious and lung cancer after repeated and prolonged exposure. When using power or hand tools, on Hebel products, wear a P1 or P2 respirator and eye protection. When cutting, routing or chasing Hebel products with power tools, use dust extraction equipment and wear appropriate hearing protection. Refer to the appropriate Hebel MSDS.

For further information, contact CSR Panel Systems or visit the website: hebelaustralia.com.au
Reinforcement exposed during cutting is to be coated with a liberal application of Hebel corrosion protection paint.

Hebel Design & Installation Guide Appendix A – Carpet Installation

Panel Surface Preparation

Sweep the floor surface to remove debris and loose particles. Expose all surface blemishes such as chips, cracks, gaps, ridges or the like. Fill all unacceptable locations with an appropriate and compatible patching compound such as Hebel® Patch or levelling compound as required.
Ensure panels are then dry.

Carpet Smooth Edge Installation

Installation of Carpet Smooth Edge (Gripper) is to be in accordance with AS/NZS 2455.1:1995.
Installation of carpet gripper prior to laying carpet requires the use of specifically selected nails or course threaded screws. Standard fixings supplied with the carpet gripper are not suitable for fixing to Hebel® PowerFloor™ panels. Carpet gripper strips are available without factory supplied nails. For carpet gripper installation near the panel edge, only glue is recommended. If relying on glue only, the carpet can not be stretched until the glue is set after approximately 24 hours.
