Porch screens can become quite loose over time due to wind, harsh weather, and other factors, regardless of how well (or tight) they were installed. Generally speaking, a standard fiberglass porch screen will require replacement every year. High-quality screens made from durable materials tend to last longer than the cheaper alternatives. Vinyl porch windows from Sunspace come with screen material installed in the system. We are able to use lighter material because the windows protect the screens from wind damage. This material creates better visibility and maintains an outdoor feel. Rather than investing in replacement material (and your time) each and every year, consider a lifelong investment to enclose your porch, extend its use, and enjoy more time in your outdoor space rather than maintaining it.
