Available in uPVC or timber, they can be finished in a wide selection of colours, including an extensive RAL palette on selected systems, alongside a choice of authentic woodgrain finishes.

A range of finishes is available, including antique black, polished chrome and polished brass, allowing you to match traditional or modern interiors. Optional heritage details such as astragal bars can also be incorporated to enhance the authentic appearance and reflect classic architectural detailing.

Our uPVC sliding sash windows combine traditional appearance with modern engineering, offering an ideal solution for homeowners seeking classic charm without sacrificing performance. These windows are designed to closely replicate traditional timber sash windows while delivering excellent thermal efficiency and security.
Featuring a slim mid‑rail for improved sightlines and a deep bottom rail to reflect authentic sash proportions, uPVC sliding sash windows achieve a highly traditional aesthetic. These carefully considered design details help maintain heritage character while allowing more natural light into the home.
Alongside their appearance, uPVC sliding sash windows offer impressive energy efficiency. High‑performance double glazing, draught‑resistant seals and multi‑chambered frames work together to reduce heat loss, helping to maintain a comfortable indoor temperature and lower heating demand. This modern specification supports improved energy efficiency while keeping maintenance requirements to a minimum.
By blending classic design with modern materials, uPVC sliding sash windows provide a durable, low‑maintenance alternative to timber, delivering long‑term performance with an authentic sash window look.
