18mm Square Fascia Boards

Whilst all of our UPVC fascias have a manufacturer’s guarantee of at least 10 years, they will often last 20 to 30 years when installed correctly.

Unlike timber boards, UPVC fascias are a low maintenance roofline option since they are not prone to rotting or warping and do not need to be stained or painted. Instead, PVC boards only need to be wiped down with soapy water once a year or so. So whilst they may be slightly more expensive than timber boards upfront, PVC is actually the more cost-effective option over time.

The measurements of all of the fascia boards on our website are measured externally. So for example, on a 150mm wide fascia board, when viewing the cross section, the 150mm width spans the top of the plain end of the board all the way down to the outer side of the return leg.

Standard fascia boards usually measure 16mm-18mm in thickness, whereas capping boards are 9-10mm thick. Whilst both are used as fascia, standard fascia boards are designed to be used as a full replacement of traditional timber fascias, which is why they are sometimes referred to as replacement fascias. Capping boards however are fitted directly onto existing timber fascias that are still in good enough condition, and are mainly fitted for aesthetic purposes.
