Abstract
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 substrate.
Claims20
A cellular glass insulation system comprising a plurality of cellular glass insulation segments and a modified gypsum cement applied on an interface between adjacent cellular glass insulation segments;
- wherein the modified gypsum cement comprises a gypsum cement base, water, and a waterproofing element in an amount of 5% to 40% by weight of the gypsum cement base.
A method of insulating a pipe, the method comprising
- mixing a gypsum cement base, water, and a waterproofing element to form a modified gypsum cement;
- providing a plurality of cellular glass insulation segments, each cellular glass insulation segments comprising a length, two side joint sections extending the length of the cellular glass insulation segment, and two end joint sections;
- applying the modified gypsum cement to at least one joint section;
- and
- positioning the cellular glass insulation segments about the exterior of a pipe.
