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 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 replacement windows
Helpful answers before you decide.
Choosing new windows is easier when you understand the collections, styles and options available. These answers help you plan with confidence.
1. Which TWC window collection suits my home?
The right collection depends on your property style, budget and preferred finish. Extreme UPVC is a strong all-round choice, Envisage Flush UPVC offers a more traditional flush appearance, and Eclipse Aluminium creates a slim, modern look. A TWC advisor can help compare each option against your home and priorities.
2. Can I mix different window styles?
Yes, many homes benefit from combining different window styles across different rooms. For example, you may want casement windows for everyday areas, fixed glazing for extra light or shaped windows for feature spaces. TWC can help make sure the overall appearance still feels consistent from the outside.
3. How do I choose window colours?
Start by looking at your brickwork, roofline, doors and existing exterior finishes. Some homes suit classic white or subtle heritage shades, while others work beautifully with modern aluminium colours. TWC can show you colour and finish options in person, making it easier to choose confidently.
4. Will new windows improve comfort?
Modern replacement windows can help improve comfort by reducing draughts, heat loss and outside noise compared with older designs. The frame material, glazing and installation quality all matter. TWC can recommend options that suit how your home feels now and what you want to improve.
5. Can windows improve kerb appeal?
Yes, replacement windows can make a major difference to your home’s appearance. Frame style, colour, glazing bars, handles and proportions all affect the finished look. Choosing the right collection and style can help your home feel smarter, more balanced and better cared for.
6. What should I do before requesting a quote?
Think about which rooms need new windows, what you dislike about your current ones and whether you prefer a traditional or modern look. Photos, rough measurements or inspiration images can be helpful, but they are not essential. TWC can guide you through the next steps.
