Abstract
Methods of fabricating wall panels by generally continuously pultruding a wall panel profile comprising inner and outer layers, and spaced reinforcing webs and/or foam extending between the inner and outer layers, optionally studs extending inwardly from the inner layer, away from the outer layer. The so-continuously pultruded wall panel optionally has male and a female edges. The wall panel is periodically cut for wall panel height, thereby creating an ongoing stream of cut wall panels. The panels are advanced through a corner index station, and indexed at right angles while maintaining orientation of the panels. The wall panels leave the indexing station edge-to-edge. Resin is applied to facing edges of adjacent wall panels. Adjacent wall panels are joined to each other at the facing edges, to make a generally continuous wall panel. The so-joined wall panel is cut to desired lengths. The resulting wall panel can provide tough, water-proof, otherwise weather-proof, building systems and buildings, without structural use of concrete except in floor slabs.
