FRAME MEMBER OF SYNTHETIC RESIN-MADE WINDOW FRAME

摘要

PROBLEM TO BE SOLVED: To provide a frame member of a synthetic resin-made window frame substituted for a polyvinyl chloride foam product having no problem such as environmental pollution or the like, having the same or more weatherability and impact resistance as those of the conventional polyvinyl chloride foam made-window frame and making little difference in the two products in terms of a price. SOLUTION: The window frame of the synthetic resin-made window frame is constituted of a deformed extrusion-molding product making a substrate as an ABS foam and a surface layer as an AES or an AAS.
