Why Twinfix Uses Polycarbonate and Aluminium

Twinfix rooflight and canopy systems are built using aluminium and polycarbonate because the combination delivers strength, safety and long-term performance. Aluminium provides a lightweight yet robust structural framework that is naturally corrosion-resistant and requires minimal maintenance, making it well suited to demanding external environments. Polycarbonate complements this with exceptional impact resistance, high levels of light transmission and superior durability, offering a safer and more resilient alternative to traditional glazing materials.

Polycarbonate Options and Benefits

Twinfix polycarbonate is available in multiwall sheets in opal and clear, as well as solid options in clear, obscure, and Georgian wired. All versions share the same long‑lasting strength, hard‑wearing durability, and excellent impact resistance, with each tint offering its own visual style. Used throughout our canopies, rooflights, and vertical glazing, polycarbonate provides a dependable, low‑maintenance solution with UV stability, strong weather performance, and thermal options where required.

Georgian Wired Polycarbonate

Traditional Georgian wired glass rooflights and canopy glazing remain common across the UK rail network, particularly within listed or heritage station buildings. However, while historically used to meet earlier safety standards, wired glass is fragile and prone to cracking, corrosion and long-term deterioration, creating ongoing maintenance demands and increased asset risk in operational rail environments. Twinfix offers a solid polycarbonate alternative that replicates the traditional Georgian wired appearance while delivering far greater durability, impact resistance and reduced weight. Integrated within non-fragile roof glazing systems, this solution is well suited to rail and heritage refurbishment projects where maintaining the original visual character is important but improved safety, performance and longevity are required.

Powder-Coated Framework

Structural integrity is provided through precision-engineered aluminium framework, selected for its corrosion resistance, strength and extended design life. Aluminium offers long-term durability while remaining lightweight and fully recyclable. Twinfix structures are finished using high-quality polyester powder coating, available across the full RAL range to allow seamless integration with façades, cladding systems and surrounding architecture. Enhanced coating specifications can be provided for coastal and rail environments where exposure levels, pollution and vibration demand additional resilience.

Timber-Effect Powder-Coated Aluminium

Our latest innovation is a timber-effect powder-coated aluminium finish for Twinfix canopy frames and roofing components, combining the classic appearance of timber with the durability and longevity of aluminium. Created using a specialist powder-coating process that replicates the texture and warmth of natural wood, it is ideally suited to heritage, rail and conservation projects where maintaining a traditional aesthetic is essential. Unlike timber, aluminium will not rot, warp or require regular repainting, providing a long-lasting, low-maintenance solution designed for demanding external environments. The result is a canopy system that preserves the visual character of historic architecture while delivering the strength, reliability and corrosion-resistant performance expected from modern Twinfix systems.

Compliance, Durability & Design Life

Panel and finish selection is always considered alongside structural loading, fire performance, UV resistance and whole-life cost. Materials are specified to minimise maintenance requirements while supporting sustainable construction through durability and recyclability. By combining high-performance polycarbonate glazing with robust aluminium finishes, Twinfix delivers canopy and glazing systems designed to perform consistently, integrate confidently and remain fit for purpose for decades.
