D5 BUILDING BOARDS – DIRECT FIXED CLADDING SYSTEM MANUAL
D5 Building Boards have been manufactured by SVP Industries Pty Limited of Tasmania, Australia since
1982, (in New Zealand they are marketed under the brand name MASADA) by Southern Plastic Extrusion Pty
Limited. They have been used successfully in regions as diverse as the cyclone regions of Northern Australia,
the cold of Southern New Zealand and the Chatham Islands.
D5 Building Boards and accessories are classified as Type A uPVC wall cladding as prescribed in the joint
Australia/New Zealand standards AS/NZS 4256 & AS/NZS 4257.
EXPANSION AND CONTRACTION
All uPVC building boards expand and contract with temperature changes. A feature of D5 Building Boards
is that they are fixed through slots to allow for this movement. The benefit of this is that the boards will
remain straight (subject to the framing) when fixed in accordance with the recommendations in this manual.
D5 Building Board is a very versatile material and with a complete range of fixing trims. The trims are
easily cut to size and are installed in conjunction with a compatible silicon sealant as required. Thus any
problems which arise in unusual situations, particularly when recladding, can be resolved.
A weather-tight building envelope is required. It is the responsibility of the designer, builder and contractor to
ensure sound design principles are followed including where the sealants are used in conjunction with
flashings. Care must be taken by these persons to ensure installation has been carried out correctly.
Only some silicone sealants are approved for use with the D5 Building Board (Masada) Twin-wall uPVC wall
