Extruded polystryene is used in many industrial applications for the insulation of piping in a close cell application. The polystyrene pipe insulation that GLT Products fabricates is an excellent solution for cold applications and is effective at not absorbing moisture.
FOAMULAR is ideal for below grade applications. Extruded polystyrene (XPS) is resistant to degradation from material common to most soils and will retain its insulating performance characteristics even after prolonged exposure to moisture.
