uPVC Windows That Preserve the Look of Your Home

uPVC is a fantastic material in many ways, offering low maintenance performance, weather resistance, and energy efficiency.

Visually, however, some uPVC windows simply cannot authentically recreate the distinction of heritage architecture. Lower-quality frames often lack detailed mouldings, creating an obvious artificial appearance that clashes with period homes, a problem furthered by the glossy plastic finishes many use. When looking to replicate the look of real wood an unconvincing grain imitation can really stand out, especially when installed in an older property.

Thanks to all of these factors, those seeking replacements that live up to the craftsmanship of original windows are often disappointed with the visual options of the finished product. Sash Windows London expertly manufactures uPVC sash windows that flawlessly replicate the aesthetics of the finest timber windows, so you avoid any hint of artificiality marring your home’s elegant period facade.

How Our Experts Replicate Period Window Looks

Every uPVC sash window we produce is custom-made to your specifications, with a huge range of designs available.

Every proportion from the mouldings to the astragal bar designs can be fabricated to precisely match your existing windows or the period look you want to replicate. Choose your preferred Georgian bar layouts, sash horns, lift styles, and hardware finishes in brass, chrome, or graphite to emulate original details.

In terms of our convincing woodgrain look, you’ll also be able to choose whether to have woodgrain on both faces or just the exterior, further allowing you to customise your interior look. With bespoke manufacturing, you’ll have complete creative freedom to tailor the sash window design perfect for your home.
