Abstract
A building curtain wall is formed by vertical frame members carrying panels of glass bridging the space between the members so that edges of the panels are mounted on the members. Each frame member is a hollow pultruded member defined by a thermo-set resin reinforced by reinforcing fibers including longitudinal rovings and a mat located at an exposed surface of the inner wall and the side walls of the generally rectangular member. The exterior surface is defined by the resin which is pigmented but uncoated. In order to provide a required finish to the exterior surfaces the inner wall and the side walls have a thickness of at least 0.090 inch with a difference in thickness therebetween which is less than 20%.
