Abstract
Wall panels and building walls, comprising inner and outer layers, and spaced reinforcing webs extending between the inner and outer layers. Optionally studs extend inwardly from the inner layer away from the outer layer with one of the stud legs on each stud being aligned with one of the reinforcing webs, or the building load delivered to an underlying footer varies less than 50% per 10 foot length of the wall, or height of the wall varies no more than 0.25 inch over a 40 foot length of the wall. The resulting wall panel can provide tough, water-proof, otherwise weather-proof, building systems and buildings.
