Cellular Glass insulation has become widely accepted as the preferred material in numerous piping, vessel, roofing and underground applications. It has exceptional water resistance with no increase in weight at up to 90% humidity, can outperform other insulation materials in high moisture conditions, and is resistant to swelling and shrinkage.
It comes in a variety of shapes and can easily be cut to install on pipes, ducts and equipment. It is often used in low temperature or extreme cold applications.
Cellular glass remains non-combustible in extreme fire hazard conditions, with excellent flame spread and smoke developed ratings. It is also extremely stable throughout its service life.
A less expensive alternative that can be used for some low temperature applications is polyisocyanurate.
