Swish Shiplap Cladding

Fascia & Soffits

Swish’s robust cellular PVC cladding profiles in traditional styles, with complementary joints, trims and fixings. Cellular PVC cladding is an ideal substitute for timber cladding; it will not discolour, retains its appearance, is virtually maintenance free and is weather resistant. A traditional Shiplap cladding profile for horizontal installation. The visible bottom edges are square.

Fitting Tips:

Shiplap should be securely nailed to a sound timber framework, suitably treated with preservative, in all external situations.

The first plank is located on the starter trim and nailed in place through the fixing groove at the top edge, using fixing nails at the minimum indicated centres.

To ensure the cladding lays flat, fixing should commence at the centre of each plank length, working progressively outwards.

All shiplap ends must be secret nailed (at their top edge) into the vertical trims. Allow a 4mm clearance at each end for expansion for white profiles and 8mm for foiled and coloured cladding (where joint covers are used, their spacing lugs will automatically provide 4mm clearance between adjacent plank lengths).

If using joint covers (as opposed to centre joint trims), install tight to the plank ends as work proceeds. All joint covers should be fixed over supporting battens. Joint covers should be staggered.

Fit subsequent planks over the preceding row, ensuring that the tongue and groove joint is firmly closed, so that the nail heads are concealed by the overlap.

Check visually for line and level every two rows. Should the top plank require cutting – this may occur at top of panel or under openings – cut top edge of plank to required depth or profile.

Planks cut as above require support at their top edges by means of packing pieces at the fixing points. Pieces cut from cladding offcuts may be suitably used. Complete by inserting the male part of any two-part trims.
