FOAMGLAS® Prefabricated Half Shells (PSH)

Description

FOAMGLAS® Prefabricated Half Shells (PSH) are designed to insulate straight pipes in both industrial and commercial applications. These half 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.
