This clear grid multiwall polycarbonate hollow sheet adopts multi-layer grid internal structure. It delivers much higher rigidity and load bearing performance than ordinary double-wall PC sheet, suitable for large span roofing projects. It keeps high light transmission for daylighting and provides outstanding thermal insulation to save energy. Optional co-extruded UV protective layer prevents yellowing under sunlight for outdoor applications. The panel is lighter than glass with excellent impact resistance and good sound insulation. Custom dimensions and colors are available.

Large-span building skylight & daylighting roof

Greenhouse, agriculture planting roof

Commercial atrium, exhibition hall, stadium roofing

Carport, canopy, walkway roof

Noise barrier and architectural partition
