MultiPlex boards are 22mm thick tongue and grooved rigid insulation boards. They can be used externally in place of a breather membrane - not only do they protect the building envelope from wind and rain but they also provide an additional layer of insulation which prevents cold-bridging across the timbers. In addition, a factory applied hydrophobic coating enables them to be used as a temporary wall/roof covering for up to one month.
MultiPlex boards are fully biodegradable.
• Insulating breather membrane for roofs and walls
• Insulating internal lining board (can be plastered)
Suitable for 20º roof pitches and above.
Suitable for rafter / support centres up to 850mm.
MultiPlex boards do not provide racking strength. Racking strength, if required, can be achieved with metal strappings or by using a suitable internal lining board. Please consult your structural engineer.
MultiPlex boards must be protected from rain and rising damp at all times prior to installation.
Protect edges of boards from being damaged.
Cut boards using a fine-toothed circular saw with guide and integral dust extractor.
Install boards with writing facing outwards and with rising tongue. Fully engage board joints (tongue and groove). Butt joints should be primed and taped. Boards are generally fixed with clout nails at 330mm centres or less. It is recommended that boards are fixed by nailing through the counter batten, thereby avoiding any risk of nail or screw heads penetrating the watertight layer.
