Colour changes the look of a casement window from both the street and the room. Swift Aluminium groups its uPVC casement windows by finish, so start with the look you want and then check the details of the exact window you plan to order. This guide helps you compare finishes without losing sight of size, layout and glazing.
Start with the windows already on your home
Look at the frames that will remain after the work. A new window beside an existing one can look different even when both are described as white or grey. Consider the front elevation, the room it faces, nearby doors and any trim you intend to keep. If an exact match matters, ask for a physical finish sample or confirmation before ordering; screen colours and photographs are only a starting point.

Compare the finish ranges
The white casement windows range is a useful reference if you want a light, neutral frame. For a softer grey, browse agate grey casement windows. The anthracite grey and black collections offer darker alternatives. You can also compare wood-effect collections such as Irish oak.
Those links are shopping ranges, not a promise that every finish is available with every window style or option. Open the relevant product, inspect its images and select the colour in its configurator. Check the internal colour separately where the form offers that choice. If the product title, image and available colour options do not agree, confirm the finish with Swift Aluminium before checkout.
Choose the window layout before finalising colour
Casement windows in the same finish can have different pane and opening arrangements. Compare the product drawings and the window opening you need rather than choosing from colour alone. Check which sections should open, how the handles will be reached and whether the design suits the existing aperture. Confirm the required arrangement with your installer if you are replacing a window.
Check the order options together
On the Casement 1 white uPVC window page, the form asks for outside frame width and height in millimetres and says to include the cill in the overall height. It then offers glazing, patterned glass, cill, trickle-vent and thermal options. Other window listings may differ. Review each selected option, the final specification and the displayed price before adding the window to the basket.
- Confirm the outside frame measurements and any fitting allowance with your installer.
- Check the finish on the exact product and whether the inside colour differs from the outside.
- Compare the pane layout, opening sections and glazing choices.
- Review cill and ventilation requirements for your project.
- Read the product’s current technical and delivery information before ordering.
When you are ready to compare designs, return to the uPVC casement windows category and open the colour range that best fits your home.
