Abstract
A corner joint between two frame lineals of a pultruded window frame is defined by inserting a leg of a corner member into a hollow interior of each lineal and attaching the legs to the lineals by adhesive. Each leg has a plurality of surfaces thereof each having a first portion at the corner which lies closely adjacent a corresponding surface of the first lineal and a second portion, at the end of the first portion remote from the corner which tapers inwardly away from the corresponding surface of the first lineal such that a spacing therebetween increases in the direction away from the corner. The adhesive is applied to the tapered portion and the taper acts to force the adhesive along the leg to the first portion and to the ends of the lineals where the excess can be wiped away.
