A perfect window choice for your property year-round, in summer, casement windows ensure you get all the ventilation you need, while in winter, their highly energy-efficient credentials mean you stay warm and toasty. Available in a variety of colours, materials and finished – we’re sure that we can find a window to match your style. 

We supply and install around South London, but we’d be willing to go further if your project is a good fit.

Casement Window Installation

Here at Osborn Glass we’ve been supplying and installing beautiful casement windows to homeowners across London, the Home Counties, the Southeast and beyond since 1966. As such, we have vast experience in fitting windows in the most efficient and timely way, minimising any inconvenience to you and your family.

Available in a Variety of Materials

uPVC Casement Windows

With uPVC casement windows, you get a classic look in a material that will never rot, flake or peel. As well as looking fantastic, uPVC windows are incredibly energy-efficient and highly durable – so you can rest assured that security is taken care of. Also, uPVC windows require almost no maintenance over their lifetime and are available in a fetching woodgrain finish.

Wood Casement Windows

For those seeking a genuinely traditional look in their home, our timber casement windows are the ideal option. Stunningly crafted from either hardwood or softwood, stain finishes or micro-porous paint help ensure the timber lasts for many, many years – while looking fantastic. Those with older buildings – including listed or period homes – often require timber casement windows to maintain the desired look, or due to local regulations.

Aluminium Casement Windows – for a Modern Look

If you own a newer or recently-renovated building, then our aluminium casement windows deliver a distinctly contemporary look. These windows possess the slimmest profile in our range, with larger glass areas for optimal light. And when it comes to durability and security, aluminium frames are a great choice. These low-maintenance windows are available in a range of inspiring modern colours.

 What is a Casement Window?

Our selection of casement windows includes our most energy-efficient and secure options. They are well suited to narrow or tight spaces and can open to the left or the right, up to a full 90 degrees for a fire escape or pushing out from the bottom. An easy-clean function can also be added for those hard to reach areas. Most models feature a fold-down handle which is cranked to open or close the window.
