A stressed-skin building panel including structural strengthening members located alternately adjacent the two opposite skin members of the building panel, each of the structural strengthening members being spaced apart from the opposite skin member by a block of high-density rigid foam material, and the remainder of the space between the skin members being occupied by a foamed-in-place foam insulating material adhering to the skin members and structural strengthening members and providing a significant amount of strength and resistance to compressive stresses. The opposite skin members are spaced apart from one another and held together at the proper spacing during and after construction by a plurality of bridge members which form the only direct connection between the skin members by other than insulating foam material, so that the insulating quality of the panels is maximized.

A thermally insulating structural panel, comprising: (a) a pair of oppositely located panel skins; (b) a first plurality of wooden strength members located between said panel skins, each extending along and being adhesively connected to a first one of said panel skins, said strength members of said first plurality being oriented parallel with each other and being spaced apart along said first one of said panel skins; (c) a second plurality of wooden strength members located between said panel skins, each extending along and being adhesively connected to a second one of said panel skins, said strength members of said second plurality being oriented parallel with each other and with the ones of said first plurality of strength members, and being spaced apart along said second one of said panel skins and located along said panel alternately with respect to said ones of said first plurality of wooden strength members; (d) a respective filler block of rigid synthetic foam insulating material attached by an adhesive to each of said wooden strength members and to an opposite surface of the oppositely located one of said panel skins, substantially filling the available space between each of said strength members and the oppositely located one of said panel skins; (e) a plurality of wooden edge stiffener members, each said edge stiffener member extending along a marginal portion of a respective one of said panel skins; (f) a plurality of edge gap filler blocks of rigid synthetic foam material located between respective opposite ones of said edge stiffener members; (g) a plurality of apart-spaced bridge member means extending perpendicularly between said panel skins and being attached fixedly to respective ones of said edge stiffener members for maintaining a predetermined distance between said panel skins; and (h) said strength members, said filler blocks, said edge gap filler blocks, and said panel skins defining a plurality of voids located between said panel skins, and a quantity of foamed-in-placed synthetic foam insulating material entirely filling each of said voids and adhesively interconnecting said panel skins, said strength memers, said edge stiffener members, and said filler blocks, so that said bridge member means and said foamed-in-place insulating material join said panel skins into a unified load-bearing structure in which loads are shared by said panel skins and said strength members, but wherein no wooden structural member other than said bridge member means extends from one of said panel skins to the other thereof.
