Before you start installing the uPVC Cladding

Please follow the instructions below before you start installing your brand new uPVC Cladding.

  • Firstly and most importantly, please ensure all Health & Safety guidelines are followed – we don’t want you having an accident whilst replacing your uPVC Cladding.
  • recommends that our uPVC cladding be installed over a timber stud frame or over a masonry or block substrate and should be fixed to a preserved treated timber batten. 

  • Cladding fixing points should be no further apart than 600mm for White Cladding, and 400mm for Woodgrain or coloured Cladding.

  • Installation begins by fixing trims (2 part U- Channel Cladding Trim  G2UCW or Cladding U – Trim GUCW ) around the area of which you wish to clad, for 90 degree corners please use 2 Part External Corner Trim G2ECW.
  • Shiplap Cladding is fixed using stainless steel cladding pins (GCP30) positioned along the grove (datum line) which runs the entire length of the uPVC cladding.
  • Pinning the shiplap cladding should take place from the centre of the boards working outwards. Subsequent lengths are fitted over the preceding length ensuring the tongue and groove joint is located and the cladding pin heads are concealed by the overlap. Please also allow for 5mm expansion gaps at each end, either vertically or horizontally.
  • Shiplap Cladding is supplied in 5m lengths, to join lengths please use either Shiplap Cladding 150mm Joint Covers GSJ150W or Cladding Centre Joint Trim GCJW.
