Kolorseal Ltd, the UK’s leading specialist in colour coatings, has observed an increasing trend among high-end builders and fabricators who are opting for dual colour frames on windows and doors. This approach allows for different colour options on the internal and external parts of the frame, introducing new possibilities for bespoke renovations and new build designs.
One notable benefit of Kolorseal’s services is the attention to detail regarding internal rebates. For every project, rebates are matched to the internal colour, a feature often unavailable with foiled window options. This ensures a consistent and polished finish throughout the interior.
Deborah Hendry, Managing Director of Kolorseal Ltd, emphasises that foiled frames typically do not cover rebates on window or door frames. From a design perspective, this can result in an odd appearance. However, Koloseal’s approach ensures a harmonious finish, which addresses this common issue.
Design Considerations and Customisation for Homeowners
Homeowners are increasingly seeking to update traditional windows with customisation options that reflect individual style and preference. This not only offers an alternative look that seamlessly blends a home’s interior and exterior but also extends the growing dual colour trend to a wide variety of doors.
Case Study: Navy and Anthracite Dual Colour Frames
One Kolorseal project showcased a striking dark navy kitchen paired with matching frames, resulting in a beautiful aesthetic. The external frames were finished in anthracite grey to complement the exterior design. Internally, the dark blue finish provided significant depth, enhancing both the modern and traditional styles.
Navy finishes are trending with homeowners who want to achieve a distinctive look and added value to their properties.

Timber Effect Foils and Ivory Themes
Contrasting timber effect foils on the exterior with ivory-themed interiors helps highlight the natural beauty of traditional properties. This not only improves kerb appeal but also increases the overall value of the home.
Versatile dual colour coatings such as grey paired with subtle blues or other pastels deliver excellent colour tones throughout interiors, supporting various design themes.
A light timber-effect external finish adds rustic charm and richness to the project. When contrasted with ivory or other pastel shades inside, this enhances the appeal of both contemporary and period homes.
Changing Perceptions of Window Colours
Deborah Hendry concludes “While some believe white is the only suitable colour for internal window design, this view overlooks the evolving needs of modern homeowners.”
