Twinfix polycarbonate panels, combined with robust glazing bars, offer an excellent solution for enclosing canopies and walkways. Available in 16mm structured polycarbonate for superior insulation and strength, and clear 6mm polycarbonate for a clean, transparent finish, these systems provide durability without compromising on light transmission. The lightweight yet impact‑resistant materials make installation straightforward while ensuring long‑lasting performance in all weather conditions. Ideal for commercial, educational, or public environments, Twinfix glazing solutions create bright, sheltered spaces that enhance usability and protection throughout the year.
Vertical glazing offers a range of benefits for creating bright, functional, and visually appealing spaces. By allowing natural light to flood into enclosed areas, it reduces reliance on artificial lighting and helps create a welcoming environment. Vertical glazing also provides excellent visibility, enhancing safety along walkways and improving overall aesthetics. Its sleek, modern appearance can complement a wide variety of architectural styles. Additionally, quality glazing materials provide strong weather protection, insulating against wind and rain while maintaining clarity and durability. Easy to maintain and versatile in design, vertical glazing is an ideal solution for canopies, shelters, and covered walkways.
Different light transmission options in vertical glazing—ranging from opal to fully clear—offer tailored benefits for a variety of environments. Opal glazing diffuses sunlight, reducing glare and creating softer, more comfortable illumination while maintaining privacy. Mid‑translucent options provide balanced light entry with partial visibility, ideal for areas needing brightness without full transparency. Clear glazing delivers maximum light transmission and unobstructed sightlines, enhancing safety, openness, and visual connection to surrounding spaces. By selecting the appropriate level of clarity, designers can optimise aesthetics, comfort, and functionality to suit any canopy, shelter, or walkway application.

Options range from full‑height glazing that creates a fully enclosed, protected environment to half‑height panels that provide shelter while maintaining openness and airflow. Partially enclosed solutions offer a balanced approach, giving weather protection without fully enclosing the structure. These tailored configurations ensure the glazing integrates seamlessly with canopies, walkways, shelters, and building façades. With custom sizing, materials, and light‑transmission choices available, bespoke vertical glazing delivers the ideal combination of functionality, aesthetics, and user comfort, designed specifically around customer needs.
