Metal reinforced sash is old technology. APCO uses fiberglass to reinforce vinyl windows. Fiberglass is considerably less conductive than metal and eight times stronger than vinyl. The use of fiberglass in APCO’s windows allow them to withstand 140 mile per hour winds and yet be more energy efficient than standard metal reinforced windows.
