The enduring elegance of vertical sliders, also known as sliding sash windows, has graced British homes for generations. Modern advancements have transformed this classic window style, combining their timeless design with modern performance.
For homeowners and installers seeking the best of both worlds—traditional style and contemporary performance, sliding sash windows offer a perfect solution. In this blog we’ll look at why sliding sash windows from Great Harwood might be the perfect choice for new windows or a replacement project.
From the subtle detail of near invisible corner welds to the graceful curve of the ovolo frame, every element is designed to impress. Responding to the growing demand in premium developments, we’ve expanded our customisation options with new designs and a bespoke colour service, empowering you to create the ideal timber window alternative, at a lower price. Including Chartwell Green, Irish Oak and Golden Oak, we offer a wide range of colours and woodgrain finishes to perfectly compliment the window design and boost its visual appeal.
We’ve increased the historical authenticity of our sash windows with refined sash window features. The introduction of the new 37mm slim midrail rather than a standard midrail solidifies Great Harwood Windows’ range as a leading choice for period properties and conservation areas, offering an unparalleled level of historical accuracy.
Complemented by options such as run through sash horns with mechanical joints, astragal bars, tilt knobs, lift hooks, heritage locking systems, pole eyes, travel restrictors and a selection of period appropriate colours and woodgrain foils, these windows are designed to preserve and enhance the character of the building whilst letting the maximum light into the rooms.
Our range includes a unique deep bottom rail and carefully crafted bottom section of the window to maintain historical proportions. Each sash is assembled with heritage hardware options, giving them an authentic appearance and functionality. We also provide a variety of hardware options.
For those wanting the most authentic sash windows, our range combines classic aesthetics with cutting edge design. These windows are designed to minimise heat transfer and hit high energy rating standards.
Whether you’re looking to recreate the look of the Victorian era or seeking Georgian sash windows, sliding sash windows from Great Harwood Windows can be manufactured to suit your project perfectly. Our windows come with equal sized top and bottom sashes (50/50 split) as standard, however we can manufacture other split ratios at your request (minimum transom drop of 350mm). If you have gorgeous views you’d like to maximise, then non-bar or Half Georgian bar layouts will give you the very best uninterrupted views while retaining the period aesthetic and meeting all the building regulations.
For great thermal efficiency, noise reduction, and to comply with modern standards, all of our windows are designed with multi-chambered profiles, warm edge spacer bars, and double glazing with low E glass that reduce heat loss and improve energy efficiency. This helps lower your energy bills, providing both comfort and cost savings. Our sash uPVC windows are our most energy efficient option.
