Abstract
An insulation and structural panel is disclosed. The panel includes a resin matrix which has a thermal conductivity less than about 1.3 BTU-in/hrFt.sup.2 .degree.F. in the unreinforced condition, and hollow glass fibers. The hollow glass fibers have a void fraction within the range of from about 20 to about 50 percent, and the panel has a thermal conductivity of less than about 1.6 BTU-in/hrFt.sup.2 .degree.F. The hollow glass fibers comprise form 60 to 95 percent by weight of the panel.

An insulation and structural panel comprising a resin matrix which has a thermal conductivity less than about 1.3 BTU-in/hrFt.sup.2 .degree.F. in the unreinforced condition, and hollow glass fibers, the hollow glass fibers having a void fraction within the range of from about 20 to about 50 percent, the resin matrix constituting an amount within the range of from about 5 to about 40 percent of the weight of the panel, the glass fibers constituting an amount within the range of from about 60 to about 95 percent of the weight of the panel, and the panel having a thermal conductivity less than about 1.6 BTU-in/hrFt.sup.2 .degree.F.
An insulation and structural panel comprising a foamed resin matrix which has a thermal conductivity less than about 0.6 BTU-in/hrFt.sup.2 .degree.F. in the unreinforced condition, and hollow glass fibers, the hollow glass fibers having a void fraction within the range of from about 20 to about 50 percent, the hollow glass fibers comprising an amount within the range of from about 60 to about 95 percent of the weight of the panel, and the panel having a thermal conductivity less than about 1.6 BTU-in/hrFt.sup.2 .degree.F.
An insulation and structural panel comprising a resin matrix which has a thermal conductivity less than about 1.3 BTU-in/hrFt.sup.2 .degree.F. in the unreinforced condition, and hollow glass fibers, the hollow glass fibers having a void fraction within the range of from about 20 to about 50 percent, the panel having a surface coating on at least one of the major faces of the panel, and the panel having a thermal conductivity less than about 1.6 BTU-in/hrFt.sup.2 .degree.F.
