AmeriLux | Frequently Asked Polycarbonate Question

Q: What are closure strips?

A: Typically made of foam or plastic, closure strips are designed with a profile that matches the configuration of a corrugated panel. Closure strips seal the opening created where the corrugated polycarbonate sheet meets a flat surface, filling the gap in corrugated roofing and sidewall applications.

Closure strips provide a finished, professional appearance and increase the weather-tightness of polycarbonate corrugated panels by preventing moisture, insects, and debris from getting under the panels.
