W20 is the most slender hot rolled window suite available in New Zealand. It was introduced to New Zealand circa 1960 and was primarily used in commercial projects.
It is designed to take single, putty, or angle steel beaded glazing. Today it is used in both residential and commercial projects for both architectural and some fire-rated applications.
