It’s all in the details
From UPVC and aluminium colours to carefully chosen window handles, every detail helps shape the final look of your new windows. TWC gives you the choice to personalise your design, creating windows that feel beautifully matched to your home.
Classic shades and woodgrain finishes
There is no exaggeration on our part when we say that we have hundreds of shades, textures and wood effects you can pick from. Finding a colour to match your property will be so simple as we have the perfect mix of traditional colours and emerging favourites. Trial different colours with one of our consultants to discover a shade you love.
Sleek finishes for modern homes
TWC firmly believes in the 11-stage powder-coating method that we employ when adding finishes to our Eclipse aluminium windows. When we undertake that process it causes strong paint adhesions to be induced and makes for the most wonderful of finishes. Sublimation is the act performed for those customers wanting a modern aluminium woodgrain. Available in Rosewood, Oak and Walnut, these woodgrains brilliantly mimic authentic woodgrains.
Finishing touches that matter
Simple window operation and the styling of a window is very dependent on the hardware that’s affixed to the design. Without this hardware, a window would be unfit for purpose and lack aesthetic beauty. So, give hinges and handles your full attention and select hardware that will make your windows as pretty as they are functional.
Customise your casement windows
Personalise your new windows with decorative and practical glazing options that add privacy, character and style while keeping your home bright, welcoming and beautifully finished.

Common questions about casement windows
Casement windows are an incredibly popular window option for a reason. If you have any questions about our casement windows or would like to know more about our range, read some of the answers to our most commonly asked questions below or contact our team for advice.
1. Why choose casement windows?
Observing and understanding casement windows helps explain their popularity.
Being hinged enables an expansive opening to be generated with a casement window, maximising external views and ventilation. Working on an outward swinging motion uncomplicates the task of cleaning and maintenance. Closure of a casement window’s tight seal also restricts draughts and heat loss, promoting energy efficiency in the home and keeping heating costs down.
Over countless years, casement windows have demonstrated compatibility with several architectural styles and unfailingly inject timeless style into homes. They rarely look out of place; such is their all-round versatility.
Manufactured using robust materials and the latest technological advancements, casement windows are an enduring solution and offer sustained weather resistance. They perfectly marry together functionality, aesthetic beauty, and energy efficiency, which is why they’re the favourite window of so many residents in Swindon and beyond.
2. Do casement windows open inwards or outwards?
An outward opening is most common with casement windows.
You open a casement window with an outward swing of the design and the exercising of it expands the external view, promotes lots of ventilation, and makes maintenance an easy job. The composition of a casement window helps it seize fresh air from outside and divert it inwards to instil a coolness in rooms on hotter days. Closure of the window creates a tight seal to ensure your safety and stop draughts infiltrating your living space.
3. How long will my casement windows last?
Like everything we produce and sell at TWC, our casement windows are built to last for years.
Our first-class craftsmanship and the materials we select help us to produce casement windows that endure in looks and performance. Window upkeep is minimal but integral to prolonging the life of our designs so that they continue to provide the thermal comfort, aesthetic beauty, and functionality that they’re meant to for as long as possible.
Quality is something that TWC is synonymous for providing and our casement windows epitomise this in every conceivable way, promising dependable and enduring quality. Put your faith in TWC for casement windows that do more than just uplift your home’s appearance, but also add value and assurance.
4. What are casement windows made from?
Casement windows can be provided in UPVC or aluminium.
The casement window is the longest surviving window style in Britain and still retains huge appeal with the nation’s householders.
We offer this classic window variation in two material choices – UPVC and aluminium. Which of them you select should be based on the look you’re seeking to achieve, what level of durability you want, and how much you’re willing to pay.
Aluminium casement windows are notoriously sleek, prioritising glass over frame, creating the slenderest sightlines due to the widened glazed section, helping to draw in floods of light. Although aluminium is exceptionally lightweight, it’s suitably strong to function as a reliable window frame.
Our premium UPVC casement window frames are more or less maintenance-free and come in at a very budget-friendly cost. They will insulate your home well beyond the standards of traditional designs, keeping in the heat you want and concealing your interiors from draughts.
