What is a flush window?

Flush windows have taken the home improvement industry by storm over recent years, allowing homeowners to enjoy the look of traditional timber windows, with the thermal performance of uPVC. We’re approved installers of The Residence Collection, arguably the best flush windows available.

Flush windows are designed to imitate timber windows. Where the windows open, there isn’t an external lip – the opening part of the window instead sits flush against the frame. This detail looks very similar to how timber windows are made, allowing homeowners to achieve a traditional look without compromising on thermal performance. Not only that, but uPVC flush windows don’t need to be painted like their timber alternatives. A wipe down from time to time with a cloth and some uPVC cleaner is the only maintenance that your flush window frames will need.

Aside from being flush, there are other details that also help to achieve a traditional timber look. Features include Georgian bars, traditional hardware, and decorative corner posts.

Why choose flush windows

Style and substance

Modern flush casement windows have all the features and traditional aesthetic of the original historical iterations without any of the issues.  Your windows will look beautiful but also tick the box when it comes to thermal performance, which is crucial in these times of increased energy bills. 

Heritage

If you live in a period property, or within a conservation area, and want to upgrade your windows whilst retaining the character, flush windows are a great option. This style will suit a wide variety of older style homes or heritage properties, come in a range of styles, colours and finishes and can feature Georgian bars, traditional hardware and decorative corner posts.

Modern

Flush windows are not just a style reserved for period homes, they look just as effective in more modern properties due to their sleek, streamlined design, making even the most ardent minimalist happy with the clean lines and smooth exterior. 

Energy performance

Flush windows are available double or triple glazed, keeping the heat out in the summer months and contained in the colder weather.

The Kömmerling Flush 70 system will work in both traditional and contemporary homes. This new range of timber alternative flush windows combines an authentic aesthetic and modern technology, with a wide range of configurations available.

Available double or triple glazed, beautiful heritage options offered include flush exteriors with durable, fully-welded joints and traditional furniture including tear drop and monkey tail handles, with an option for an astragal bar. 

Window design has evolved in recent years, with more use of large openings, helping to accommodate larger areas of glass that can be achieved particularly well with the Kömmerling Flush Sash. Large side openers and fixed lights offer perfect window symmetry and the maximum passage of light. These windows also offer perfect architectural appeal, whatever the property and location. There’s also the benefit of a wide range of standard and bespoke finishes inside and out.
