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)
Performance
Suitable for 20º roof pitches and above.
Suitable for rafter / support centres up to 850mm.
Racking strength
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.
Storage
MultiPlex boards must be protected from rain and rising
damp at all times prior to installation.
Protect edges of boards from being damaged.
Cutting
Cut boards using a fine-toothed circular saw with guide
and integral dust extractor.
External applications
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.
