The go-to window for Sunderland homes — reliable, low-maintenance, and engineered to perform across decades. Installed by Range Windows
Suits All Property Types
From 1930s semis to contemporary new builds, casement windows are the universal choice — clean, unobtrusive, and available in configurations to match any elevation.
Excellent Ventilation
The full-opening side hinge allows maximum airflow compared to top-hung or tilt-only windows — ideal for kitchens, bathrooms, and living rooms where fresh air matters.
Easy to Clean & Maintain
The outward-opening sash allows you to clean the outer face from inside — particularly useful on upper floors. uPVC frames require no painting, staining, or sealing.
Casement is a broad category — the hinge style, configuration, and opening direction all vary. We supply and install all standard casement types across Sunderland and Tyne and Wear.
The standard casement — hinged on the left or right, opening outward. Suitable for ground and upper floors. Available as single or double casement (two opening sashes within one frame).
Hinged at the top and opens outward from the bottom — often used as a ventilation light above a fixed pane. Provides secure background ventilation without a large open gap.
The sash sits flush within the outer frame rather than projecting proud of it — giving a sleek, flat appearance popular on contemporary and barn-style properties. See our flush windows page for full details.
Casement sashes fitted within a projecting bay or bow frame. The most common configuration on Sunderland semi-detached properties — typically a three-panel bay with a fixed centre light flanked by two side-hung casements.

A casement window is hinged on one side and opens outward — to the left or right. It is the most widely installed window style in the UK, suited to virtually all property types. The opening sash sits within a fixed outer frame and is operated with a handle and multi-point locking system.
Casement windows open outward on a side hinge, while tilt-and-turn windows open inward and offer two modes — tilted at the top for ventilation, or fully open for cleaning. Casements are more traditional in appearance; tilt-and-turn windows are popular for upper floors where outward opening poses a risk.
Yes. Modern uPVC casement windows use multi-chambered profiles, argon-filled glazing, and warm-edge spacer bars to achieve A or A+ energy ratings. Our casement windows meet Building Regulations Part L as standard. For maximum performance, we also offer A+ rated triple glazing.
Yes — casement windows can be specified as escape (egress) windows to meet Building Regulations requirements for habitable rooms above ground floor. Escape casements require a minimum clear opening of 0.33 m² with no dimension less than 450mm. We advise on the correct specification during the free survey.
Our uPVC casement windows are available in white, cream, anthracite grey, black, rosewood, golden oak, Irish oak, and chartwell green — plus dual-colour options. Contact us for a full colour brochure.
Quality uPVC casement windows typically last 20–25 years before the sealed glazing units begin to fail. The frames can last 30 or more years with minimal maintenance. All our installations carry a 10-year guarantee on products and workmanship.
In most cases, no — replacing casement windows falls under permitted development rights. Exceptions include listed buildings, conservation areas, and some new-build estates. We will advise if any restrictions apply to your property during the free survey.

Fantastic experience with Lee from Range Windows. Prompt efficient service, windows swiftly measured up and date of installation agreed. Call on the day of installation to confirm the time and Lee arrived as agreed. Fab installation and exceptionally happy with the product. Will definitely recommend.

Had a new door fitted by Range Windows and Doors today, door looks amazing and service was brilliant. Everything was all cleaned up after the job was finished too which was a bonus. Highly recommended.

Definitely recommend this company! Service is 5 star, they try to help any way they can. Fitting me in to fit a low profile door so my wheelchair could get in my new home. The door is easy to work, draft free and feels very secure and solid. A very caring genuine company which is hard to find nowadays.

Adam and Brad came early, on time and got to work straight away. They worked hard, fitting 3 new bedroom windows then a back door — all finished in the day. Every item was installed well. They cleaned up everything inside and out, taking all rubbish away with them. Thank you for your good work.

Within a day Adam came to the house for a free quote — no pressure, no rush. Very professional and we chose this company just from how Adam represented them. Lee measured everything up within days, giving honest advice where other companies were saying to replace everything. Outstanding service.

I couldn't recommend these guys enough! Service was spot on start to finish. Lee and the guys are so knowledgeable about their products, even dropping off brochures so I could make a decision in my own time. No pressured sales, just down to earth people. Adam and Brad fitted the door — so professional.
