Why compromise on elegance when you can have both style and security? Our sliding sash windows are designed to maintain the classic charm of period homes while offering the latest in modern safety features. Each window is A-rated for energy efficiency, helping keep your home warm and reducing your energy bills.

Available in a wide range of colours and finishes, these windows are fully customisable to suit your home’s style—from traditional whites to contemporary woodgrain textures. The double-glazed units are toughened for extra security, and every window comes fitted with travel restrictors to prevent accidents and a tilt-in mechanism that makes cleaning simple and safe.

With Oakwell, you get a solution that’s not only practical and low-maintenance, but also enhances the curb appeal of your property. And, of course, all our sliding sash windows come with a 10-year insurance-backed guarantee, giving you complete peace of mind.
