Abstract
A glass fiber insulation product includes irregularly-shaped glass fibers of two different glasses having differing coefficients of thermal expansion, with the irregularly-shaped dual-glass fibers exhibiting a substantially uniform volume filling nature, and providing improved recovery and thermal conductivity abilities even in the absence of a binder material.
Claims15
An insulation product comprising irregularly-shaped glass fibers having a substantially uniform volume filling nature, the insulation product having a recovered density within the range of 0.3 to 0.6 pcf (4.8 to 9.6 Kg/m.sup.3) after compression of the insulation product to a compressed density within the range of 6 to 18 pcf (96 to 288 Kg/m.sup.3).
An insulation product comprising irregularly-shaped glass fibers, the insulation product having a recovered density within the range of 0.3 to 0.6 pcf (4.8 to 9.6 Kg/m.sup.3) after compression of the insulation product to a compressed density within the range of 6 to 18 pcf (96 to 288 Kg/m.sup.3).
An insulation product comprising binderless irregularly shaped glass fibers having a substantially uniform volume filling nature, wherein the irregularly-shaped glass fibers are sufficiently entangled that the binderless insulation products has integrity upon suspension under its own weight, the insulation product having a recovered density within the range of 0.3 to 0.6 pcf (4.8 to 9.6 Kg/m.sup.3) after compression of the insulation product to a compressed density within the range of 6 to 18 pcf (96 to 288 Kg/m.sup.3).
