An improved shim such as is used to wedge between door frames and walls in construction applications. The improved shim is made of a non-wood material which resists splintering, splitting, and compression. It also resists decay, rot and degradation over time. The shim is an elongated wedge-shape. It can include transverse slots, grooves, or scores which make it frangible at various locations along its length to size it to different lengths. The improved shim can be manufactured linked end-to-end and foldable into a compact stack.
