Abstract:
1. A method of manufacturing a window or door frame comprising: providing a first frame lineal formed from a fiber reinforced pultruded material and defining a constant transverse cross section extending longitudinally, the transverse cross section having interior surfaces at least partly surrounding a hollow interior; providing a second frame lineal formed from a fiber reinforced pultruded material and defining a constant transverse cross section extending longitudinally, the transverse cross section having interior surfaces at least partly surrounding a hollow interior; providing a corner member; the corner member having a first leg portion for insertion into the hollow interior of the first frame lineal; the corner member having a second leg portion for insertion into the hollow interior of the second frame lineal; the first and second leg portions being connected each to the other at the corner at an angle to hold the first and second frame lineals in fixed connected position at the angle; arranging the first leg portion to have a plurality of surfaces thereof, each of which surfaces is arranged to lie closely adjacent a corresponding surface of the first frame lineal for adhesive attachment thereto; each surface of the first leg portion having a first portion at the corner which lies closely adjacent the corresponding surface of the first frame lineal and a second portion, at the end of the first portion remote from the corner, which second portion tapers inwardly away from the corresponding surface of the first frame lineal such that a spacing therebetween increases in the direction away from the corner; arranging the second leg portion to have a plurality of surfaces thereof, each of which surfaces is arranged to lie closely adjacent a corresponding surface of the second frame lineal for adhesive attachment thereto; each surface of the second leg portion having a first portion at the corner which lies closely adjacent the corresponding surface of the second frame lineal and a second portion, at the end of the first portion remote from the corner, which second portion tapers inwardly away from the corresponding surface of the second frame lineal such that a spacing therebetween increases in the direction away from the corner; applying a layer of an adhesive onto at least the second portions of the surfaces of the first and second leg portions of the corner member; and inserting the leg portions into the respective one of the first and second frame lineals so as to squeeze the layer of adhesive onto the first portions of the surfaces of the first and second leg portions and onto the ends of the frame lineals to provide a seal therebetween.
