Our 10mm UPVC Cover Boards are available in nine colour options and they come in a range of sizes from 100mm to 275mm (this varies depending upon the colour choice).Cover boards are generally used for covering existing timber fascia or window boards, but they are also used on new installations. In new build applications a timber backing board is used behind the cover board to support it along its length (we recommend 25mm thick sawn timber).Cover boards are measured externally including the bottom return leg, ie. a 200mm Cover board will cover 190mm of existing timber. The return leg measures 40mm overall (30mm Internal).PVC cover boards should be fixed using 2 x 50mm Polytop Nails no further than 600mm apart for white boards (max 400mm for woodgrain coloured boards). This means that you should allow 18 nails for each 5m length in white, and 26 for colours.
