Lincolnshire manufacturer enhances customisation options and production capacity with new windowline, delivering greater flexibility for construction specifiers and buyers.

George Barnsdale, a Lincolnshire-based manufacturer of high-quality timber windows and doors, has invested £1.2 million in a new windowline, as part of a £2 million upgrade at its Donington factory.

This significant upgrade reinforces George Barnsdale’s position as a leading British manufacturer, and expands the company’s ability to deliver bespoke solutions, accurate replication and complex customisation for construction specifiers and buyers.

Established in 1884, George Barnsdale has remained a family-owned business rooted in the local community for over 140 years. The new windowline represents the company’s long-standing commitment to combining traditional craftsmanship with modern technology to meet evolving customer needs.

This investment reflects our commitment to delivering quality and precision for our customers, strengthening our ability to provide highly customisable timber windows and doors with certified performance, and long life low maintenance.

Tom Wright, Managing Director at George Barnsdale

“By integrating advanced automation across our extensive product range, we can offer exceptional flexibility and consistency without compromising on quality or cost.“

“The new windowline integrates seamlessly with our existing operations, expanding what we can create whilst maintaining the exceptional craftsmanship standards we’re known for.”, Louis Kam, Operations Director at George Barnsdale, goes on to express.

Greater flexibility for demanding architectural projects

The new windowline introduces advanced manufacturing capabilities across George Barnsdale’s product range, including casement windows, doors, sliding sash windows and tilt-and-turn windows. The enhanced process enables the company to handle extensive customisation variations, providing architects and designers with exceptional flexibility for complex specifications and intricate detailing.

Key improvements include:

  • Expanded customisation options supported by upgraded software
  • Superior finishing with an advanced coating system delivering enhanced durability and reduced maintenance requirements
  • Improved weather sealing, joinery details and glazing performance for long-term reliability and performance
  • Enhanced aesthetic detailing with refined profiles and new extended design options
  • Component-based production enabling faster development and introduction of product improvements

Strengthening George Barnsdale’s market position

When asked what sets George Barnsdale apart from its competitors following the new windowline, Tom commented, “Many manufacturers are investing in this type of machining technology, but the difference for us is the system behind it”

By linking the windowline directly to our ERP and product data, we’ve created a level of ongoing flexibility that supports our full product range, rather than restricting it. That capability is backed by an extensive, considered design and testing programme, allowing us to certify a much broader range of designs and sizes with confidence.

George Barnsdale’s latest investment reinforces its commitment to advanced, data‑driven manufacturing. By linking the new windowline directly to its ERP and product information systems, the company has created a flexible production environment that supports its full product range.

Combined with a rigorous design and testing programme, this capability enables the confident certification of a wider variety of product designs and sizes, strengthening George Barnsdale’s position as a leader in precision manufacturing and innovation.

Increased capacity and efficiency

The integrated system combines cutting, machining, coating, and assembly processes in one continuous workflow, delivering improved accuracy and consistency. The investment increases production capacity and improves turnaround times, supporting the company’s growth plans.

The windowline forms the first phase of broader plans to introduce new machinery across the Donington factory over the coming years.

“The new windowline transforms our manufacturing process,” said Louis. “With components produced in one continuous workflow, we achieve a superior finish, more reliable performance and the agility to innovate more quickly in response to customer needs.”

Supporting British manufacturing

“We’re proud to be a British manufacturer investing in our capabilities and our team,” Tom added. “This investment strengthens our Lincolnshire operations and allows us to maintain quality control whilst supporting local jobs and expertise. It benefits our customers, our team and demonstrates our commitment to British manufacturing.”

By combining over 140 years of craftsmanship with cutting-edge technology, George Barnsdale continues to differentiate itself through its ability to manufacture timber windows and doors that others simply cannot produce. The company’s focus on innovation and bespoke solutions sets new standards in the industry for architects, designers and homeowners seeking truly customised products.
