Heritage Style, Contemporary Performance
Experience the best of both worlds with our sliding sash windows.
Every detail, from the traditional proportions to the elegant ovolo profiles, has been carefully crafted to replicate authentic period windows. However, unlike historic sash windows, these classic designs are crafted using modern uPVC. This allows homeowners across Essex and Suffolk to benefit from excellent energy efficiency, robust security, and effortless operation. We also offer a selection of woodgrain foils for those looking to replicate the look of timber windows.
Sliding Sash Windows: Why Opt For uPVC?
While timber sliding sash windows have graced British homes for centuries, our uPVC alternatives offer the same traditional beauty with significant modern advantages.
Unlike timber designs, our uPVC sliding sash windows never need painting, sanding or treating, and won’t rot, warp or deteriorate over time. More cost-effective than traditional timber and fully recyclable, these windows offer the perfect balance of classical design and modern practicality.

A sliding sash window is a classic window design which consists of two sashes that slide vertically to open. Each sash moves independently within the frame, allowing for ventilation. This window style is commonly seen on Victorian and Georgian properties, but is also a popular choice for use in contemporary homes.
How energy efficient are your sliding sash windows?
Our uPVC sliding sash windows achieve impressive U-values as low as 1.2W/m2K, thanks to their 24mm double glazing units and advanced profiles. This superior thermal performance helps keep your home warm while potentially reducing energy bills.
What colours and finishes are available?
We offer a wide range of colours, including authentic woodgrain finishes that replicate traditional timber.
How long will sliding sash windows last?
Our sliding sash windows are built for longevity and come with a comprehensive 10-year insurance-backed guarantee. The durable uPVC construction ensures they maintain their performance and appearance for years to come.
Can they be cleaned easily?
Yes - many of our sliding sash windows feature a tilt function that allows both sashes to tilt inwards, making cleaning the exterior glass safe and simple.
