Our exclusive fiberglass strategically weaves rovings with our structural mat, is set with heat-activated resin and finished with a heavy-duty powder coat finish. It resists chalking and fading to keep your sleek patio doors beautiful with less maintenance, and meets AAMA 624, which is a highly-rated fiberglass coating.
