Description
Aluminum extrusions for polycarbonate panels provide a rigid structural support, edge protection, and weatherproof sealing for greenhouses. Single “H” (edge/trim) and Double “H” (joining) extrusions manage panel expansion and secure multiwall sheets.
Single “h” Extrusion (Edge / Termination Profile) – 12′
- Function: Used to hold down a panel edge, finish a perimeter, or cover an open end wall.
- Design: Features a single channel slot with a flat backing or screw flange, acting like a combined U-channel and termination trim.
- Key Features: Shields open panel edges from dirt, insects, and moisture intrusion. Provides a clean, professional endpoint at doors, vents, or gable flashing.Â
Double “H” Extrusion (Connector / Joint Profile) – 12′
- Function: Used to seamlessly join two adjacent polycarbonate sheets side-by-side along their length.
- Design: Features a symmetric H-shaped cross-section (available in 1-piece slide-in or multi-piece base-and-cap configurations with gaskets).
- Key Features: Spreads load pressure evenly across framing members to prevent stress cracking. Accommodates natural thermal expansion and contraction of plastic panels. Creates a watertight or weather-resistant structural seam.
