When it comes to sash window restoration, we can provide timber frames that match the authenticity and look of the original building.

We are industry leaders when it comes to custom manufacture of like-for-like replacement windows, making use of state-of-the-art technology to provide modern standards in sash windows.

Classic Elegance Meets Modern Standards

With a wide selection of classic and modern styles and finishes, our traditional timber sash windows are the perfect complement to any architectural design. Whether you’re working on a new-build project or refurbishing an existing property, we offer a fit and finish to suit your specific requirements.

At TRC Windows, we understand that eye-catching style is just one aspect of window design. That’s why our timber sash windows feature a double-sealing gasket system, ensuring unparalleled weather tightness. Our commitment to thermal performance is exemplified by a remarkable U-value as low as 0.79 on our triple-glazed flush casement windows, providing both style and energy efficiency.

Our easy-clean timber sash windows offer the same design versatility as our other sash windows, with options including hardwood or softwood frames and a range of RAL three-coat spray applied factory finishes. Choose from four glazing options: safety, obscured, acoustic, and solar control. As standard, our timber sash windows are double-glazed, with the option for triple-glazing for enhanced performance.
