ABSTRACT:
Dimensional stability of melamine decorative laminates is improved by a pair of spaced, foraminous steel foil layers, which resist shrinkage of the melamine layer. Steel foil layers are also used to prevent splitting of low-strength wallboard cores as a result of shrinkage of melamine facings, and each facing need have only a single steel foil layer in the case of a wallboard.
