Why UPVC? UPVC offers a durable and attractive replacement for older materials prone to degradation. From the fascias and soffits around the top of your property, to the drainage systems hidden underground, our UPVC products give long-lasting peace of mind. FH Plastic for Fascias and Soffits: Our roofline range allows replacement of rotten fascias and soffits in a selection of finishes –including wood grain foils- to get the right look for your house. As well as complete replacement, we offer 9mm Coverboard fascia (also known as cappit board, or clad-over board), which gives the benefits of low maintenance UPVC over the top of existing sound wooden fascias.
