Superior Window Frame Durability
All Renewal by Andersen® replacement window frames are made of Fibrex® – our superior composite material that is more durable than vinyl. Unlike vinyl, Fibrex® won’t expand and contract easily, thus breaking the glass seal and requiring immediate attention more often. Instead, Renewal by Andersen® replacement window frames are made to weather the Florida temperature changes while remaining narrow. In other words, you’ll reap the benefits of both enhanced frame longevity as well as optimized window visibility.
