20mm Fascias

Sturdy, durable 20mm replacement fascia boards are an ideal replacement for timber due to their low maintenance and thermal insulation properties.

The lightweight fascia boards are insect, vermin and fire resistant and feature an impermeable skin that prevents corrosion from the elements.

Our easy-to-fit, cellular uPVC 20mm fascia board joints are available in white or black, light oak, mahogany and rosewood foiled finish.
