How to fit uPVC cladding

Updated April 17, 2017

uPVC, or unplasticised polyvinyl chloride, is a weatherproof, lightweight and cost-effective material installed as cladding or siding to a structure. In addition to this, it is highly durable, and boasts high levels of ultraviolet light protection. Installing uPVC siding may be a laborious task, but will provide a finish that will last for years.

Affix wooden batten boards around the bottom of the perimeter of the area you will be siding, using your screwdriver and 3.8 cm (1 1/2 inch) screws.

Screw battens vertically from your horizontal line up to the top of the area you will be covering. Space them 60 cm (2 feet) apart, and saw them to a length that leaves a gap at the top of the surface for another ring of horizontal boards.

Repeat step 1, but this time at the top of the area you will be covering.

Use a jigsaw to cut the rows of cladding to fit the width of your surface.

Nail a flange for your first row of cladding to the bottom horizontal row of battens, then slide the first cladding panel onto this flange. This provides a nice finish to the bottom row of cladding panels. Start at the bottom and work your way up, nailing each panel through the top into the vertical boards, and overlapping the panel above.

Nail another flange for the horizontal trim to the top row of batten boards. Cut the trim to fit and hang it in place on the flange to ensure the nails in the top row of cladding panels are not visible.
