Modern Twist on Traditional Design

Flush casement windows feature all the design cues of a bygone era in British architecture while boasting all the benefits of modern double or triple-glazed windows.

Once a staple of 18th-century buildings, these elegant window frames are a design feature in themselves and are seeing a revival with the incorporation of modern frame materials such as UPVC and multiple-layer glazing.

Whether you’re going for a modern or more traditional aesthetic, flush casement windows make an excellent addition to any home.

Aesthetics and Energy Efficiency

Flush casement windows have come a long way in terms of design since the 1700s and are now made using the very latest in manufacturing technology. Frames are now made largely using either aluminium or UPVC for a clean look that lasts longer with little to no maintenance, and windows themselves are double or even triple-glazed for drastic improvements in thermal efficiency.

You can completely customise the look of your windows, with huge choices of frame materials, colours, and glazing.

The Timeless Tradition of Flush Fit Windows

Look around you at any examples of 18th-century architecture, and some of the more keenly preserved examples will still feature their original wooden frame flush casement windows 

The sleek design harks back to when window frames began to be constructed more widely from wood, rather than metal. This was thanks to advancements in glass manufacturing allowing for the creation of larger panes of glass, as a pose to the smaller sections that had been used previously that necessitated heavier-duty frames.  

As architectural fashion trends have come and gone, flush casement windows have remained a staple design choice for centuries.

Your Choice of Materials

Nowadays, you can have your choice of materials for flush casement windows, the most common among which are UPVC thanks to its long life and minimal maintenance, or aluminium, also for long life and low maintenance as well as being lightweight and durable.  

Flush casement UPVC windows and aluminium windows require next to no maintenance, offer optimal thermal insulation, and can be styled using several textures and colours to appear as much like traditional wood as possible.  

Why Choose Flush Casement Windows?

Outstanding Energy Efficiency

Opting for new flush casement windows for your home will allow you to slash your energy bills with vast improvements to thermal insulation.
Our aluminium and UPVC window frame options offer up to A++ energy efficiency standards when combined with triple glazing.

Enhanced Security

As well as a fresh look and a warmer home, flush casement windows come with a roster of built-in security features to keep your home safe.
Our standard flush casement windows all feature shoot-bolt locks, key-locking handles, and toughened glass to help you rest easy.

However, flush casement windows could be your solution. Their design is compatible with the requirements of most UK conservation areas, thanks to their adherence to traditional appearances, and large range of material and colour choices.

Protection from the Elements

As their name suggests, flush casement windows provide a tight, flush seal against their frames. This works to keep the weather outside and your home free from drafts and cold, even in our ever-changing UK climate.

Frequently Asked Questions

How much do flush casement windows usually cost?

Prices of flush casement windows can vary based on a few factors, including what frame material you opt for, the size of the windows, as well as the glazing level that you choose.

At Haus Installations, we’ll work with you to find the right options at the best possible price.

Flush casement windows vs. casement windows?

The primary differences between flush casement and casement windows are all aesthetic. Casement windows have an external lip where the sash meets the frame, whereas flush casement windows do not.

Both offer outstanding weather resistance, and which is right for you is largely a design choice.

Are flush casement windows energy efficient?

Yes, very. Even wood frame options begin at an A-rating, and UPVC frames with triple glazing can take you all the way to A++ grade thermal efficiency.

Should my windows be flush with my house?

Put simply, that’s up to you. Some homes and areas suit flush casement windows better, and some will suit casement windows. Which option you choose is down to you. At Haus Installations, we can help walk you through all the variables to find the right window choice for your home.
