Twinwall and multiwall polycarbonate sheets consist of multiple layers separated by internal ribs, forming air pockets that enhance thermal insulation compared to single-layer polycarbonate sheets. This design improves energy efficiency for various applications.
These sheets are widely chosen in construction projects for their lightweight nature combined with strong impact resistance, flexibility, and UV protection, making them suitable for both indoor and outdoor use.
Henry Gallacher supplies twinwall and multiwall polycarbonate sheets, typically provided in clear as standard. Alternative finishes such as opal and bronze can be arranged upon request.
