The perfect finish

Create the perfect finish with a casement that sits flush against the frame. Thanks to its sleek and minimalist design, a flush casement window can help you achieve that traditional country home aesthetic, without compromising on energy efficiency, security or weatherproofing.

All of our products are made to measure, so we can create a solution that meets your exact requirements. You can choose a charming French-style window or opt for Georgian bars inside and out. Windows are available double or triple glazed. Whichever style you choose, the frame will be designed to make your job as easy as possible, ensuring that the quality of the fit matches the quality of the build.
