• 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.
The OutRWALL™ system has been assessed by Warrington Fire Research
in their assessment Nos. WFRA C91580 and WFRA C91585 for fire-ratings
of 1 hour and 1.5 hours. The system must be assembled in accordance
with the relevant assessment.
Acoustic performance may be improved with variations in plasterboard,
stud and/or partition width and choice of insulation. These variations
offer a wide choice of attainable Rw values. For details, contact
"Lightweight Cladding" includes, but is not limited to:
• Fibre cement sheets, profiles and weatherboard;
• Timber or hardboard weatherboards;
• Steel or aluminium profiles; and
Note: Cladding does not include materials with a self ignition
temperature of less than 200°C except where the fire rating is from
the outside only.
Where conventional construction can not be used due to difficult
access, the Boral OutRWALL™ exterior wall system may be prefabricated
prior to erection.
Boral Plasterboard is manufactured in accordance with Australian
Standard A.S. 2588 - 1983 "Gypsum Plasterboard" and is to be installed
generally in accordance with the requirements of Australian/New
Zealand Standard A.S/NZS 2589.1:1997 Part 1 "Gypsum Plasterboard".
Specify to meet project requirements.
All materials, unless otherwise indicated, shall be manufactured
by Boral Plasterboard, and shall be installed in accordance with
its current printed instructions.
Delivery and Storage of Materials
All materials shall be delivered in their original unopened packages
and stored in an enclosed shelter providing protection from damage
and exposure to the elements. Damaged or deteriorated materials
shall be removed from the site.
Timber framing to receive plasterboard lining shall be structurally
sound, free from bow, and in general compliance with Building Code
requirements. Damaged and excessively bowed studs shall be replaced
before installation of plasterboard lining. Timber framing shall
approximate the moisture content it will reach in service by allowing
the enclosed building to stand as long as possible prior to the
application of plasterboard. Do not install plasterboard over wet
