Casement Windows Built to Specification

We will tailor the design of your product to suit the exact requirements of your Southampton project.

Our versatile approach means that we’ll create double glazing that ticks boxes across the following criteria:

  • Design. Casement windows feature clean lines. The neutral appearance of this type of window means it can be placed anywhere in a home, conservatory or extension. It can also be used in new builds or heritage properties.
  • Colour. The casement windows you install will blend in seamlessly with their surroundings. Choose from of our many woodgrain foils to recreate a wood effect and find an RAL colour to complete the look of your frame.
  • Glass. Complete your casement windows by choosing double or triple glazing. You can also select toughened glass to improve security; an obscure design can be chosen in cases where privacy is required at all times.
  • Security. Our Deceuninck profiles keep homes in Southampton safe. The locks and hinges we use meet Secured by Design standards. Internal beading, reinforced steel and other features work to further prevent break-ins.

Perfect for Traditional Properties

Although our casement windows work in almost any design scenario, the 2500 profile’s simple design makes it perfect for period homes – or properties that are older.

In terms of performance, our Deceuninck windows let in lots of space-creating light, thanks to the extensive use of glass and minimal amount of frame.

Thermal efficiency is achieved via dedicated seals that will make any home in Southampton warm, comfortable and less expensive to run.

Homes that feature our casement windows will also notice a reduction in ambient noise as a direct result of the sealing technology we use.

Easy to Use, Easy on the Eye

Casement windows supplied by Novaseal will look great – wherever you need to install them in the Southampton area.

As well as communicating stunning aesthetics, our windows use a single lever latch design that makes them easy to use.

Practical design and stunning looks combine in equal measure in this ever-popular and extremely versatile style of window.


Cost-Effective and Long-Lasting

The Deceuninck 2500 windows we supply excel at stopping warm air in its tracks. At the same time, they stop unwanted cold air from finding its way inside. All of this adds up to a home in Southampton that’s always cosy – and, just as importantly, less expensive to heat.

Unlike timber windows, ours won’t warp or rot when exposed to extreme weather conditions. Once installed, there won’t be any need to worry about condensation forming inside the panes. The super spacer technology used in each window prevents this from happening.
