Exterior Header Moulding

Exterior header moulding is a polyurethane element that caps the upper portion of window and door openings, assisting in water diversion and ensuring architectural consistency. Applied on building exterior surfaces to emphasize window casing systems and complete facade profiles. Manufactured from high-density rigid polyurethane with zero water absorption. This material structure guards the element against rain, snow, frost, and intense sunlight. Unlike wooden headers, it will not rot, and unlike plaster headers, it does not shatter upon impact. Its light statical weight eliminates extra loads on the structure and allows fast mounting via adhesive bonding. Mold casting precision delivers smooth surfaces ready for any acrylic exterior paint.
