Clear Multiwall Polycarbonate U-Channel (6mm, 16mm)

Clear Multiwall Polycarbonate U-Channels are available in two sizes: 1/4" (6mm) and 5/8" (16mm) to match the thickness of your multiwall polycarbonate panels. All U-channels are 96" long and precision-extruded from clear polycarbonate for finishing panel edges and ends with a professional, weatherproof seal. U-Channels create clean, finished edges on multiwall polycarbonate installations while protecting the exposed panel channels from water infiltration, debris, and insects. The "U" profile slides over the cut edge of panels, sealing the hollow chambers and providing a professional appearance. Essential for greenhouse construction, patio covers, and any installation where multiwall panel edges need proper finishing and protection. Perfect for greenhouse projects, patio cover construction, skylight installations, and any application where multiwall polycarbonate panels have exposed edges that require professional finishing.

Each U-channel covers one 96" edge. For greenhouse projects: measure the perimeter of all panel edges including gable ends, side walls, and door openings. Divide total edge length by 8 feet to determine the number of U-channels needed. Request a project quote or call 844-970-0650 for installation consultation. How do I know which U-channel size I need? Match the U-channel size to your multiwall panel thickness: 1/4" (6mm) U-channels for 6mm panels, and 5/8" (16mm) U-channels for 16mm panels. The channel must match exactly to properly seal the exposed panel edges and hollow chambers. Where do I use U-channels in a multiwall installation? Use U-channels on all exposed panel edges including bottom edges, side edges, around door and window openings, and any cut panel ends. They seal the hollow chambers preventing water, debris, and insects from entering while providing a finished professional appearance. How do I install U-channels on multiwall panels? Slide the U-channel over the cut edge of the panel from the side. The channel should fit snugly over the entire panel thickness. For best results, ensure the panel edge is cut square and clean before installation. The U-channel will seal all hollow chambers in the panel. Can I cut U-channels to shorter lengths? Yes, U-channels can be cut to any length using a fine-tooth saw or utility knife. Measure carefully and cut square for the best fit. Many installations require custom lengths to fit specific panel dimensions and opening sizes. What happens if I don't use U-channels on exposed edges? Exposed panel edges without U-channels allow water, debris, and insects to enter the hollow chambers, which can cause algae growth, reduce insulation properties, and create an unprofessional appearance. U-channels are essential for proper multiwall panel performance and longevity. 4.7 ★★★★★ Based on 10 reviews Tom S.
