Claims
- 1. The combination of:
- a. a panel having two major surfaces, edge portions connecting the major surfaces, and grooves in at least one edge portion, said panel being comprised of:
- i) a material which is an acoustic barrier and has sufficiently high compressive and flexural strength to enable a wall to be constructed of a plurality of such panels;
- ii) at least two foil layers, within and approximately congruent with one major surface of said panels, said foil layers being separated from each other by part of the thickness dimension of the panel and arranged so that they at least partially cover the grooves of each panel; and
- b. a mating member having a shape and dimensions which allow press fitting the mating member into a groove of the panel of part a., said mating member each being a single piece and comprising:
- i) a material which is an acoustic barrier having sufficiently high Young's modulus and compressive strength to allow a wall to be constructed of a combination of panels and mating members without fasteners which penetrate the panels or mating members; and
- ii) at least two foil layers at least partially covering the sides of the mating member, in such a way that when the mating member is inserted into the groove of the panel, the respective foil layers in the panel groove and on the mating member are in sliding contact with each other.
