When choosing new windows for your home, understanding the difference between various styles is the first step to making the right choice. One style that’s grown in popularity over recent years is the flush window.
While standard casement windows have been the traditional choice for many UK homes, flush windows offer a distinctive look that many homeowners now prefer. But what exactly makes them different, and why might you choose one over the other?
What Are Flush uPVC Windows?
Flush windows (or flush sash windows) feature opening sashes that sit flush with the outer frame, creating a sleek, flat appearance. Unlike traditional casement windows, where the opening part overlaps the frame, flush windows create a seamless look reminiscent of traditional timber windows.
The Aesthetic Difference
The most apparent difference between flush and standard windows lies in their aesthetic. Standard casement windows have been the go-to choice in the UK for decades. With these windows, the opening part of the window (the sash) sits on top of the frame when closed, creating a slight lip or step on the outside.
Flush windows are designed so the sash sits perfectly level with the frame. This creates a flat, streamlined appearance that many find more visually appealing. The smooth, even surface has no protruding parts, giving your home’s exterior a cleaner look.
This flush design isn’t new; it returns the traditional window style. Before modern manufacturing techniques, timber windows were typically made with flush sashes. As uPVC windows became popular, the overlapping sash design became standard because it was easier and cheaper to manufacture. Today’s flush uPVC windows represent a return to those traditional aesthetics but with modern materials and benefits.
Which Homes Suit Flush Windows?
Period Properties
Flush casement windows are particularly well-suited to period properties. Their design closely mimics traditional timber windows found in older homes, making them an excellent choice for:
- Victorian and Edwardian houses
- Cottages and farmhouses
- Listed buildings (subject to local planning authority approval)
- Properties in conservation areas
Because flush sash windows replicate the look of traditional wooden windows, they’re often acceptable in areas where planning restrictions might otherwise prevent the use of uPVC windows. Many local authorities recognise that modern flush sash designs respect the original character of heritage buildings while offering the benefits of contemporary materials.
This is especially true of the Residence Collection, which has been designed explicitly with heritage properties in mind. The R9 system, in particular, has gained approval from many local planning authorities for use in conservation areas thanks to its authentic 19th-century timber window appearance.
Modern Homes
It’s not just period properties that benefit from flush windows. Their clean lines and minimalist appearance work beautifully in:
- New build properties seeking a premium look
- Modern homes aiming for a cleaner aesthetic
The sleek, uncluttered look of flush windows complements modern architectural styles and can add a touch of elegance to any home.
Why Choose Flush Windows?
There are several reasons why homeowners across the UK are increasingly choosing flush windows over standard casement designs:
Aesthetic Appeal
Perhaps the most compelling reason to choose flush windows is their appearance. Many people prefer the smooth, flat look they provide. The clean lines and neat finish can improve your home’s kerb appeal.
Flush casement uPVC windows are available in a wide range of colours, including popular options like anthracite grey and various woodgrain finishes, allowing you to match any property style.
Energy Efficiency
The flush design doesn’t compromise thermal performance, offering the same excellent energy efficiency as our standard casements. Changing from inefficient wooden windows to character-appropriate uPVC flush windows can make a huge difference, reducing heat loss from your home and potentially lowering your energy bills.
Our flush window range features:
- Multi-chambered frames for improved insulation
- High-performance double or triple glazing options
- Effective weather seals to prevent draughts
Heritage Compatibility
For homeowners with period properties, flush windows provide a way to maintain traditional aesthetics while enjoying modern benefits. They’re often acceptable in conservation areas where standard uPVC windows might not meet planning requirements.
Low Maintenance
All uPVC windows, whether flush or standard, offer the advantage of low maintenance. Unlike traditional timber windows, they won’t rot, warp or need regular repainting.
