Heritage uPVC windows are made from our modern uPVC, but unlike normal uPVC windows, they’re designed to replicate the timber flush sash style. The Suffolk window comes with fully mechanical joints to perfectly recreate traditional joinery techniques and the attractive curve of an ovolo frame. Fabricated with close attention to detail, homeowners are unable to even tell the difference between heritage uPVC and real wood! With the durability and functionality of modern uPVC materials, you will instantly be able to create a traditional feel in your home, achieving the aesthetics of timber flush sash windows.
