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 Delivery and Storage

PowerBlock  Delivery

PowerBlock pallets should be unloaded and moved with only approved lifting devices. Before use, the lifting devices should be checked for the required lifting tags. PowerBlock pallets should be unloaded and stored as close to the intended installation area as possible. This will increase work efficiency and minimise the need for secondary lifting.

It is good practice to inspect the delivery for damaged blocks. Unnecessary handling will increase the risk of damage to the Hebel® PowerBlocks.

Care should be taken when cutting the packaging straps, blocks may come away and cause injury or become damaged.

TIP – When a block is damaged it may be possible to cut away the damaged section and use the remaining portion in the wall.

Storage

All materials must be kept dry and preferably stored undercover. Hebel® PowerBlocks should be left on their pallet until they are required. Place the pallet on a level and stable surface. The project engineer should be consulted as to the adequacy of the structure to support Hebel® PowerBlocks if they are not stored directly on the ground or concrete slab.
