The Richmond Heritage Timber Casement Window
Hardwood Heritage Casement Windows
The design and specification for these heritage windows was born out of a large Grade II listed project that we completed in Winston Churchill’s wartime residence on the edge of Richmond Park.
This product was designed to incorporate a number of highly traditional features to give a very traditional aesthetic, but by utilising modern design and materials, we have also been able to deliver exceptional performance. This product comes with our full 10-year guarantee on all elements and delivers energy efficiency ratings as good as our modern double glazed products.
A real alternative to slim double glazing in heritage windows:
Energy efficiency that meets modern regulations
Traditional appearance for conservation projects
More cost effective initially and in ongoing maintenance
The Winston Sliding Sash Timber Window
The perfect heritage window where authentic design meets modern performance.
Originally developed for a major restoration of Winston Churchill’s wartime residence near Richmond Park, this window was created specifically to meet the demands of Grade II Listed buildings and sensitive renovation projects.
Blending classic detailing with advanced materials, it offers the charm and elegance of traditional timber joinery without compromising on energy efficiency or durability.
Despite its heritage appearance, it delivers performance on par with our modern double-glazed range and comes backed by a full 10-year guarantee on all components.
A truly timeless solution for Listed properties and period renovations.
The Clement Heritage Hopper Timber Casement Window
Traditional Hopper Casement Windows are ideal for barn conversions and heritage projects.
Inspired by their agricultural roots, Hopper windows bring authentic character to barn and stable block renovations. Hinged at the bottom and opening inwards, they provide discreet, high-level ventilation while maintaining a traditional aesthetic.
Originally used to promote airflow over livestock, their design is now perfectly suited to modern barn conversions offering heritage style with practical performance. Each window typically includes a top-mounted fanlight catch and an opening restrictor for safety and control.
A subtle yet striking detail that stays true to the building’s history while meeting today’s comfort and design standards.
The Heritage Yorkshire Sliding Sash Timber Window
Heritage Yorkshire Sliding Sash Windows are a timeless classic, expertly recreated here.
Also known as Yorkshire Sliders, these traditional horizontal sliding sash windows are a distinctive feature of workers’ cottages and period homes, particularly across the North of England. Unlike vertical sashes, the sashes glide side-to-side, echoing the proportions and charm of the original designs. Manufactured from Accoya, the best longevity of any timber together with exceptional energy efficiency.
Historically favoured for their simplicity and lower cost, many have since been replaced with flush casements — but we continue to craft these authentic windows for Listed buildings and conservation projects where preserving character is key.
Designed with modern draught-proofing and precision joinery, our Yorkshire Sash Windows blend period accuracy with practical performance.
Toughened Vacuum Glazing, delivering U-values comparable with modern double glazing, but with a total thickness of only 6.2mm. No double refection makes it perfect for use in conservation areas.
