Permex Hurricane Shutters are identical in appearance to our custom exterior line with one distinct difference. GE's Lexan is incorporated into the panel making it impact resistant. In addition, Permex Hurricane shutters offer a simple and easy installation solution. Now you can secure panels from inside the structure by attaching the storm bar with stainless steel screws to threaded inserts permanently placed in the shutter. No more ladders or scaffolding to secure hard to reach openings. Simply close panels into the opening and secure the storm bar from inside the home.
