Sliding Sash Windows For Yorkshire Homes
Sliding sash windows are a popular choice for both traditional and modern homes. They’re perfect for period properties, townhouses, cottages, and even new builds where you want the charm of classic timber windows without the maintenance. With their authentic design, they suit loft conversions, extensions, and any space where a traditional look is needed. Each window is made to measure, with sizes available from 375mm x 800mm up to 1500mm x 2400mm, giving you the flexibility to fit almost any opening.  Our vertical sliding sash windows are smooth to operate, with two sashes that move independently on a balanced mechanism—so you can open them to any height with ease.
With our sliding sash windows, you can respect the traditions, admire the woodworker’s art, and enjoy modern advances that can warm and secure your home. From a Yorkshire-based terraced house to a stately home, our sash windows can help ensure that your property retains its character and charm. You can choose from a wide range of styles, features, and hardware options to complement your home.
The slim profiles create a sleek finish, improving both the look and the view from your home. To complete the timber-style appearance, we include authentic details like Astragal glazing bars, decorative sash horns, and traditional-style hardware. The sash sections, meeting rail, and jambs are all designed to closely match original timber sash windows, giving you the classic look with all the benefits of modern UPVC.

Add the finishing touches to your new UPVC sliding sash windows with a range of traditional-style hardware. Each window comes with tilt knobs, sash lifts, and sash locks as standard. Â You can further enhance the traditional look with optional features like integral Georgian bars, external Astragal glazing bars, and trickle vents. These extras help you achieve a truly authentic timber-style appearance. Â Our sash windows are also built with security in mind. High-performance locking systems come as standard, helping to keep your home protected.
We offer two different vent solutions to comply with Document F of the building regulations. Both vents are colour matched to match the aesthetics of our Legacy sash windows. Using the new exclusive modular vent will allow any of our welded windows over 775mm in width to comply with the new requirement to achieve 8000 EA airflow in a single window! If a certain rate of equivalent area (EA) is required, please let us know at the point of enquiry.
Traditional Sash Horns
Add a true touch of authenticity to your sliding sash windows with our premium run-through sash horns. Unlike welded horns found on standard UPVC windows, our run-through design uses precision mechanical joints. This allows the horn to remain a continuous part of the sash, perfectly replicating the look of traditional timber joinery.
This attention to detail helps your windows blend seamlessly into period properties or conservation-style homes, preserving the original character without the maintenance of wood.
For an even more accurate timber appearance, you can also choose a deep bottom rail—another classic feature of traditional sash windows. Together with run-through horns, this upgrade gives your new UPVC sash windows a truly heritage finish, ideal for homeowners who want the charm of original sash design with all the benefits of modern materials.

Sliding sash windows are a perfect choice for both traditional and modern homes. They’re especially popular in period properties, Georgian or Victorian-style homes, and conservation areas where maintaining a classic appearance is important. Thanks to their authentic design, they can be used to replace old timber windows while keeping the original character of the building.
They’re also a great fit for townhouses, cottages, and listed buildings, offering the traditional look with all the benefits of modern UPVC. Sliding sash windows are ideal for front and rear elevations, loft conversions, or anywhere that needs a timeless style with smooth operation, improved energy efficiency, and minimal maintenance.
