FOAMGLAS® Prefabricated Quarter Shells (PSQ)

Description

FOAMGLAS® Prefabricated Quarter Shells (PSQ) are designed to insulate straight pipes, particularly those with large diameters, in industrial and commercial applications. These quarter shells are fabricated from FOAMGLAS® cellular glass insulation, offering a lightweight, rigid, and durable solution composed of millions of completely sealed glass cells. This structure provides superior thermal performance, moisture resistance, and long-term dimensional stability.
