Georgian Wired Polycarbonate: A Modern Solution for Heritage Glazing

When specifying a canopy or roof glazing system, there is much more to consider than how the finished structure will look.

Safety, structural performance, access, installation, durability, future maintenance and the individual constraints of the site all have an impact on the right solution.

Twinfix Georgian Wired Polycarbonate is widely recognised for its use in rail and heritage station refurbishment projects, but its applications extend far beyond the rail sector.
Designed to replicate the traditional appearance of Georgian wired glass, it combines a familiar heritage aesthetic with the modern performance benefits of solid polycarbonate. Lightweight, highly impact resistant, UV protected and weather resistant, it provides a practical alternative to traditional wired glass for both refurbishment and new-build projects.
The material is particularly well suited to listed buildings and heritage refurbishments where maintaining the original character of a structure is important. It can also be used for school and university canopies, retail and commercial developments, public buildings, museums and visitor centres, as well as vertical glazing, overhead glazing, canopies and covered walkways.
Georgian Wired Polycarbonate can be supplied as individual sheets or incorporated into the Twinfix Multi-Link-Panel system for larger roof glazing applications.

Meeting the challenge of heritage railway glazing

One area where Georgian Wired Polycarbonate has particular relevance is the UK rail sector.
Preserving the character of historic railway stations while meeting modern standards for safety and performance can present a significant challenge, particularly when it comes to traditional canopy glazing.
For many heritage railway stations, Georgian wired glass forms an important part of their familiar appearance. However, as historic glazing ages and requires replacement, asset owners and specifiers need a solution that can retain this traditional aesthetic while delivering the safety, durability and practical benefits expected on today’s railway.
Twinfix developed its Georgian Wired Polycarbonate in-house specifically to address this challenge.
When incorporated into our Multi-Link-Panel Non-Fragile system, the Georgian wired-effect polycarbonate provides a complete heritage-sensitive canopy glazing solution suitable for demanding rail environments.

Why replace Georgian wired glass with polycarbonate?

Traditional Georgian wired glass has long been associated with railway station canopies and other historic structures. Its distinctive appearance can form an important part of a building’s character, meaning replacement with conventional modern glazing is not always appropriate.
Twinfix Georgian Wired Polycarbonate retains this visual connection with traditional glazing while providing the practical advantages of a modern material.
Polycarbonate offers high impact resistance while being significantly lighter than glass, which can be particularly beneficial when refurbishing existing and historic canopy structures.
For rail projects, the material can be incorporated within the Twinfix Multi-Link-Panel Non-Fragile system, providing a modular aluminium-framed solution with non-fragile performance tested in accordance with ACR[M]001:2019.
This allows the glazing appearance, structural system, safety, installation and future maintenance requirements to be considered as one complete solution.

Developed by Twinfix for heritage environments

Our Georgian wired-effect polycarbonate was developed and refined by the Twinfix team for buildings where heritage considerations are important.
The objective was not simply to imitate the appearance of traditional glazing. We wanted to provide architects, specifiers, contractors and asset owners with a practical way of upgrading historic canopy glazing without unnecessarily changing the character of the structure.
This has particular relevance within the UK rail sector, where historic stations often need to remain operational while ageing materials are renewed.
Over more than a decade, Twinfix Georgian Wired Polycarbonate has been specified on railway projects across the UK, including Stirling, Wigan Wallgate, Pembroke Dock, Wrexham General and Tunbridge Wells, demonstrating how the solution can be adapted to different station structures and heritage requirements.
At Grade II listed Tunbridge Wells Station alone, approximately 560m² of Georgian Wired Polycarbonate Multi-Link-Panel glazing was used during restoration of the station canopies.

Engineering for heritage at Stirling Station

Our work at Stirling Station provides one of the clearest examples of how Twinfix’s technical expertise can solve a combination of heritage, safety and maintenance challenges.

The Category A listed station required extensive roof reglazing, with the new system needing to retain the character of the historic structure while delivering the performance expected from modern roof glazing.

Georgian wired-effect polycarbonate was specified to provide an appearance sympathetic to the original glazing while offering the lightweight and impact-resistant benefits of polycarbonate.

An important aspect of the heritage requirements was retaining the appearance and proportions of the original 50mm-wide glazing bars. To achieve this, Twinfix developed a bespoke 50mm glazing bar specifically for the project.

Our design team used 3D modelling and printing technology to create a prototype of the new profile, allowing the design and dimensional tolerances to be carefully assessed before progressing to full manufacture.

The result was a bespoke version of the Multi-Link-Panel system developed around the requirements of the historic structure.

Safety and future maintenance were also integral to the solution. Twinfix incorporated 174 in-line access hatches into the roof glazing system, providing designated access points from which maintenance activities, including gutter cleaning, could be undertaken without the need for a separate roof-mounted access structure.

In total, approximately 2,440m² of station roof was reglazed as part of the wider refurbishment.

Stirling demonstrates an important aspect of the Twinfix approach. Where a project presents specific architectural, heritage or technical requirements, our design and manufacturing capabilities allow us to adapt the system accordingly, balancing appearance, safety, maintenance, installation and long-term performance.

Georgian Wired Polycarbonate at Scarborough Station

One of the latest major applications of the system is the restoration of Grade II listed Scarborough Station.
Designed by railway architect G. T. Andrews and opened in 1845, Scarborough Station retains important elements of its Victorian railway architecture.
Following a glazing failure in 2021, Network Rail developed a comprehensive programme to secure the long-term future of the station. Full restoration works commenced in 2025 as part of a £14 million investment programme, encompassing roof renewal, improved drainage, stonework restoration and improvements to passenger areas.
The project presented several challenges. The historic character of the station needed to be respected, the station had to remain operational throughout the wider works, and its coastal location meant long-term resilience was an important consideration.
Twinfix worked alongside Network Rail, Colt Construction and Orchard Roofing & Building, providing specialist design and manufacturing expertise for the station canopy glazing.
For the platform canopies, Twinfix designed and manufactured the Multi-Link-Panel Non-Fragile system incorporating 6mm Georgian Wired Polycarbonate, providing a modern glazing solution appropriate for this important heritage railway environment.
The project demonstrates exactly what our Georgian Wired Polycarbonate was originally developed to achieve: preserving the visual character associated with traditional railway glazing while introducing modern materials and safety performance.

Safety at the heart of the glazing system

Safety is particularly important when specifying railway station canopy glazing. Roof glazing is installed above platforms, passengers and operational railway infrastructure, while future inspection and maintenance requirements must also be considered.
Georgian Wired Polycarbonate provides a high-impact-resistant and lightweight alternative to traditional glass.
When incorporated within the Multi-Link-Panel Non-Fragile system, the complete glazing assembly provides non-fragile performance tested in accordance with ACR[M]001:2019.
Multi-Link-Panel can also incorporate dedicated access hatches where required, creating planned access points for future inspection and maintenance.
The result is a glazing solution designed with safety in mind throughout the life of the asset, from manufacture and installation through to future maintenance.

Designed for challenging rail environments

Replacing glazing within an operational railway station requires careful planning. Access can be restricted, installation periods may be limited and disruption to passengers and rail services needs to be minimised wherever possible.
Twinfix Multi-Link-Panels can be manufactured and assembled under controlled factory conditions before being delivered to site, reducing the amount of work required within the railway environment.
Their modular construction also means the system can be designed around different canopy dimensions, roof forms and existing structures.
This is particularly valuable for heritage railway projects, where every station presents its own combination of structural, architectural and operational requirements.

Supporting more sustainable heritage restoration

Restoring and upgrading existing infrastructure rather than replacing it unnecessarily can contribute to a more sustainable approach to the built environment.
Georgian Wired Polycarbonate can support this by allowing existing historic canopy structures to be retained and upgraded with modern glazing.
The reduced weight of polycarbonate compared with traditional glass can also be advantageous when working with existing structures, while the modular nature of Multi-Link-Panel means individual panels and components can be maintained or replaced where required rather than automatically replacing an entire glazing installation.
The aluminium and polycarbonate components used within the system can also be recycled at the end of their useful life.
Together, these features support a whole-life approach to railway canopy refurbishment, helping to extend the useful life of existing assets while improving safety and performance.

A proven solution for heritage railway glazing

Scarborough is the latest in a growing number of historic railway environments where Twinfix Georgian Wired Polycarbonate has provided an alternative to traditional wired glass.
From individual entrance canopies to extensive platform roof glazing, the underlying challenge remains the same: how do you introduce modern performance without losing the architectural character that makes a heritage station distinctive?
Twinfix Georgian Wired Polycarbonate, combined with our Multi-Link-Panel Non-Fragile system, provides a proven solution.
Developed in-house with heritage considerations in mind, it combines the appearance of traditional Georgian wired glazing with the benefits of modern polycarbonate and an engineered non-fragile glazing system.
For Network Rail, architects, contractors and specifiers working on the restoration of historic railway stations, it provides a way to preserve the appearance of the past while improving safety, durability and maintainability for the future.
