About this range & buying advice

Internal cover sills are manufactured with PVC, which makes a great window sill. You can cover your existing sill with this 3mm thick rigid UPVc cover. They are waterproof, allowing them to cope with condensation from your glazing, and they are mould-proof. With mould-proof silicone, you can enjoy years of use with no significant cleaning required. Installation is simple, and it is affordable enough to replace these sills when redecorating is required.
It is simple to cut with a fine-toothed saw, then glue into place with glue and caulk around the edges and to the window frame to seal the gap.
Sills come in primary colours: white, mahogany, and oak.
