Flush Casement Windows


Traditional Aesthetics Without the Typical Pitfalls of Traditional Windows

In contrast to stormproof windows, which overlap in the frame, flush casement windows are a classic and elegant window solution. These windows have clean lines and fit flush into the frame, making them an attractive alternative to stormproof windows. This contributes to the Flush window’s understated and sophisticated overall appearance.

The Flush casement window is an excellent addition to the Evolution collection. It was developed with the intention of producing a breathtaking focal point and features aesthetics that are traditional in nature. This timber alternative flush-fitting window is suitable for buildings replacing original flush timber windows and for people who desire authentic aesthetics but wish to benefit from modern window technology.

These maintenance-free windows have been built based on true, historic design, and they are particularly popular in period homes and cottages. However, we are seeing a rising demand for their use in contemporary new homes and minimalist conversion properties due to their clean, crisp lines. 


Why should we let functionality win out above beauty? Our Flush Window systems include stunning timber styling throughout, with handcrafted joints and fine wood appearance detailing across the whole frame. These features are standard across all of our flush window products. A minimalist’s ideal window, the Flush casement window features clean, uncluttered lines that are sure to please. Your home will receive more natural light due to the increased glass area without reducing energy efficiency.

Although this type of window has historically been installed in older homes with cottage-style architecture, the recent trend in the real estate industry is for owners and developers of more contemporary houses to install flush-style windows since it assists in maintaining the uncomplicated architectural appearance they are attempting to achieve.

The highly energy-efficient Flush window will prevent any heat from your home from escaping outside thanks to its U value, which is at least 1.4 and comes standard.

energy-saving glazing, triple glazing.

Natural Light That Takes Your Breath Away


The Invisiline option is available on every Evolution Storm & Flush window. Compared to the typical 162mm sightline across mullions, the extraordinarily slim look of Invisiline windows results from using a 127mm sightline across the mullions in constructing these windows. When it comes to increasing the amount of natural light that enters your home, the frame’s decreased thickness and increased surface area of glazing deliver the goods.
