10mm Cedral Lap Fibre Cement Cladding Board - Standard Painted - Wood Effect

Cedral Lap is an attractive, fibre cement cladding board which is an ideal low maintenance, rot free alternative to all types of traditional cladding, but with the visual appeal of natural timber. Cedral Lap is fitted in traditional lapped style. These boards are installed to the ventilated rainscreen principle - air can flow in at the base of the system, behind the cladding and then out, over the top of the weatherboard system. This air flow behind the weatherboard enables the system to remove moisture. Cedral Lap is available in 21 factory applied colours.

It is advisable to add 5-10% wastage allowance and add extra boards for window reveals depending on reveal depth.

Usage: 1.75 boards per m2

Available in two finishes: timber and smooth textures. Smooth Cedral planks are available in full pallet quantity and extended lead time. Please check by phoning in.

• Allow at least 150mm between bottom edge of the plank and the ground.
  
• Fix Cedral Lap planks. Cut them to size, where necessary.
• Place the first Cedral plank onto the starter profile. Ensure that the plank is fixed to every batten it crosses. The end of every plank must also coincide with a batten.
• Overlap the next plank by 30mm.

• Use one screw per support, if @ 400mm, then 11 nos, if @600mm, then 8 nos.
  
• The planks butt jointed against one another and the joint must coincide with a timber support. The battens should be protected with polythene under the joint.
