George Barnsdale Sash Window

Incorporating Casement, Sliding Sash and Yorkshire Sash timber windows and a variety of door types, including French Doorsets, the Historic Range offers the following key features:

Authentic Design: To replicate original designs, flush joints and solid glazing bars have been incorporated into the design of the Historic Range. To closely match the original an extensive choice of profiles and layouts, including arched top, internal arch and arch fillet designs are offered. To mirror original hardware designs, George Barnsdale have sourced a series of window and door furniture collections.

Enhanced Weather Performance: With no detriment to authentic appearance, George Barnsdale have incorporated innovative features to provide excellent protection from the elements. Their Historic Sliding Sash, Yorkshire Sash and Casement window designs incorporate concealed dual weather seals to help retain warmth and exclude noise and moisture. For the Historic Entrance Doors, Single Doors, Stable Doors and French Doorset designs they’ve integrated concealed gaskets and plugs between the door and the frame to ensure that when the door is closed, the entirety of the frame is completely sealed.

Improved Energy Efficiency: For the Historic Range, George Barnsdale provide the options of narrow cavity insulated glazing units to replace original single glazing. With slim sightlines, the narrow cavity insulated glazing units provide a compromise between energy efficiency and authenticity.

Original Glazing Methods: To accurately replicate the aesthetics and the production methods of the original window, George Barnsdale have developed an external putty glazing system. Utilising modern materials to maximise performance, they are able to provide a five year guarantee against glazing unit failure on all external puttied installations.

Excellent Security: Security is intrinsic to our design approach. Historic Casement window and all of our door designs are fitted with multiple locking points, and our Sliding Sash and Yorkshire Sash windows incorporate only the highest quality hardware to provide excellent security.

George Barnsdale have been crafting the highest quality timber windows and doors at their Lincolnshire-based factory since 1884. They blend detailed design with premium materials and cutting edge technologies to ensure their windows and doors are as enduring as they are beautiful.

George Barnsdale provide a localised, personal service through a national network of Approved Partners. Whether you’re looking to replace one window, or have an inventive self-build brief, their Approved Partners have been carefully selected to make sure you get exactly the timber windows and doors that your property deserves.

To suit a variety of property styles George Barnsdale offer three core product ranges – Traditional, Historic and Contemporary – which have been designed to provide you with years of high performance with minimal maintenance. This commitment to performance and longevity is backed by industry-leading guarantees which are reinforced by their suppliers. George Barnsdale offer the following standard guarantees across their Traditional and Contemporary Ranges (there is some variation across the Historic Range due to the authentic design details and putty glazing):

  • Paint Finish – 10 year guarantee against paint coating system failure.
  • Stain Finish – 7 year guarantee against stain coating system failure.
  • Preservative – 30 year guarantee against preservative failure.
  • Glazing Unit – 10 year guarantee for all drained and vented glazing units.
  • Hardware – 10 year guarantee for window and door hardware.
  • Weather Seals – 10 year guarantee against the failure of weather seals.

To ensure their windows and doors meet the highest standard, George Barnsdale are committed to periodic testing, with data by UKAS approved test houses to validate all performance claims.

For complete design flexibility, the Traditional, Historic and Contemporary Ranges have a wide choice of layouts, profiles, glazing, coating and furniture options. For paint and stain colours, if the colour you require isn’t included in the standard options then George Barnsdale can match to a physical sample, or to an existing RAL, Natural Colour System or British Standard colour reference. George Barnsdale also offer a choice of sustainably sourced timber, for which they can provide full FSC® chain of custody for all windows and doors upon request.
