• Solid polyurethane core adds to insulating efficiency
• Embossed pinstriping (grooves) on the embossed stucco outer skin adds strength and enhances appearance.
• Integral struts – Two 1-3/4” roll-formed struts per section increase rigidity and strength.
• 18-gauge hot-dipped galvanized steel “wrap-around” end caps offer interior hinge attachment to surface and exterior leg for proper seal against jamb
