Frequently Asked Questions

What is the difference between flush and casement windows?

In terms of functionality, the best flush casement windows are no different from standard casement windows. Both offer the same benefits in terms of security and energy efficiency, and operate much the same way. 

Where they do differ is in the design. Compared to a flush casement window, a regular casement window has a ‘lip’ which sits over and protrudes from the window unit. Flush windows on the other hand, close in line with the frame. create a flat ‘flush’ appearance from the outside. A neatly placed flush window gives a clean and minimalist touch to your windows and your home overall.

What materials do flush windows come in?

uPVC is perhaps the most popular frame material in the UK. If you prefer a r colour other than standard white, you can easily customise the colour or finish of the frames to appear more like wood or aluminium.

The benefits of uPVC

  • The most affordable option in the UK
  • Highly thermally efficient and resistant to warping
  • Lasts 20-25 years with little maintenance
  • Customisable to suit your preference

Aluminium flush casement windows

If you’re interested in a modern design aesthetic, then you should consider flush casement aluminium windows. To enhance the modern appeal, many manufacturers today make especially slimline flush-fit frames, with narrow sightlines and wider glazing panels. Highly durable and resistant to corrosion 

  • Last 25-30 years with little maintenance 
  • Thermally efficient with thermal break technology 
  • Most suited to contemporary buildings and aesthetics 

Timber flush casement windows

Flush casement timber windows also make a beautiful window combination. Timber windows have a timelessness that marries nicely with the flush casement design. Commonly found in timber flush casement windows are astragal or Georgian glazing bars which help elevate the traditional quality of the windows. 

  • Most expensive material option 
  • Highly thermally efficient 
  • Last up to 50 years with the right upkeep and maintenance
  • Customisable and decorative options 

Composite flush casement windows

Composite windows, as their name suggests, are made from a composite material that uses timber and aluminium. Typically, this consists of a timber exterior and aluminium internal cladding. This way, you can enjoy all the aesthetic qualities of timber, while reinforcing its durability with aluminium. Composite flush casement windows will cost considerably more than windows made from just aluminium or timber.
