Ejoy Corrugated Polycarbonate Roof Panel vs Twin-Wall Polycarbonate Greenhouse Panels

Buy the Ejoy corrugated panel for open deck, patio or carport roofing where you want a clear cover that sheds water and shrugs off impacts. Buy the twin-wall panel for greenhouses and insulated DIY glazing where heat retention and rigidity matter more than flexibility. The Ejoy is a single-skin sheet that bends over curvy supports and is rated 20 times stronger than 5 oz fiberglass; the twin-wall is a stiff, multi-layer sheet with 95% light transmission and UV stability. Owners of corrugated panels like the Ejoy for easy overlap and light weight; twin-wall buyers value the trapped air layer that cuts heat loss.

• Choose the Ejoy if you are covering a deck, patio or carport and need a clear, lightweight panel that follows a curved roofline.
• Choose the twin-wall panel if you are building or repairing a greenhouse and want insulation, rigidity and UV-stable clarity.
