Abstract: An insulating, substantially rectilinear building panel comprised of a top portion, a bottom portion, and at least three chambers containing interior surfaces disposed between said top portion and said bottom portion. The pressure within each of such chambers is less than about 100 millimeters of mercury; and each of the interior surfaces has a reflectivity of least about 80 percent. Each of the chambers contains a top portion and a bottom portion, and each such portion has at least two legs, each of which ends in a rounded surface. The two portions of each chamber contact each other at their respective rounded portions.

Abstract: An insulating, substantially rectilinear, laminated building panel containing a reflective outer layer, an intermediate shatter shield, and an inner insulating layer. The inner insulating layer consists essentially of soda-lime glass, and it contains at least three evacuated chambers with reflective interior surfaces.

Abstract: A covered structure comprising a covered bridge and at least one covered entrance to said bridge is described. The covered bridge contains a bridge frame, a deck, a bridge enclosure framework disposed above the deck, means for connecting the bridge frame to the deck and the bridge enclosure framework, and a glass enclosure attached to the bridge enclosure framework. The bridge enclosure framework contains a multiplicity of vertical columns and a multiplicity of roof trusses.The vertical columns and roof trusses contain at least about 45 weight percent of inorganic fiber and, in addition, a resin and/or plastic material.
