Abstract
Official abstract text for this publication.
A cellular glass insulation system for an outer surface of a structure or pipe. The insulation system includes multiple segments of cellular glass. An adhesive having a reduced permeability is provided at the interface between the individual cellular glass segments and is configured to limit water intrusion that might cause corrosion of the structure or pipe.
First claim
Opening claim text (preview).
The invention claimed is: 1 . A cellular glass insulation system comprising a plurality of cellular glass insulation segments, wherein each cellular glass insulation segment comprises a length, two side joint sections extending the length of the cellular glass insulation segment, and two end joint sections; and a modified gypsum cement applied to at least one joint section between adjacent cellular glass insulation segments; wherein the modified gypsum cement is formed from a solid component comprising a gypsum cement base and a liquid component comprising water and a waterproofing element; wherein the modified gypsum cement comprises the solid component and the liquid component in a weight ratio of about 1:1 to 3:1; wherein the waterproofing element is a wax emulsion and is present in an amount of 5% to 40% by weight of the gypsum cement base; and wherein the modified gypsum cement has a water vapor transmission rate of less than 0.002 perm-inch. 2 . The cellular glass insulation system of claim 1 , wherein the waterproofing element is present in an amount of 5% by weight to about 30% by weight of the gypsum cement base. 3 . The cellular glass insulation system of claim 2 , wherein the waterproofing element is a wax emulsion having an average particle size of about 0.1 to about 10 microns. 4 . The cellular glass insulation system of claim 3 , wherein the wax emulsion has an average particle size of about 2 to about 6 microns. 5 . The cellular glass insulation system of claim 1 , wherein the plurality of cellular glass insulation segments are sized and shaped for installation around a pipe. 6 . The cellular glass insulation system of claim 1 , wherein the cellular glass insulation segments are sized and shaped for installation on a roof of a building.
