摘要

A plastic frame for a door or window has a hollow profile construction with an inner support lip (11) for the glazing and with the outer edge of the glazing supported by an outer metal section (3). Hollow spaces (4) between the metal section and the plastic structure provide mechanical strength without requiring inner metal bracing. The metal section can be of aluminum alloy and is clipped onto the plastic frame.
