Design Notes
- Frames, stumps and footings are to be designed and installed in accordance with the requirements of AS 1684 - 1999 "Residential Timber Framed Construction" and AS 2870 - 1996 "Residential Slabs and Footings - Construction".
- Exterior cladding must be properly weather sealed for the life of the structure, particularly at ends, edges & joints. Adequate drainage should be provided for any moisture which may develop inside the cladding due to condensation or leakage.
- Boral Plasterboard drywall materials and accessories must be installed in accordance with the detailed specifications supplied in Boral Plasterboard Technical Literature.
- Limiting heights will be determined by various design criteria including wind loads, deflection limits, stud size, stud spacing and charfactor number where applicable.
- With the introduction of "Charfactor numbers" assigned to each system, the designer/builder has greater choice available for selection of framing to meet the requirements of height, axial load and fire ratings. For detailed information on how to use "Charfactor Numbers" for framing selection, refer to Boral Plasterboard "Construction Selector" - Technical Manual 100C.
- Movement or control joints should be installed: (a) where the plasterboard abuts dissimilar materials, and/or where the construction changes within the plane of the wall; (b) in long unbroken partition or wall runs at not more than 12 metre centres; and (c) as required to accomodate shrinkage of timber.
