Chemical-Resistant Cellular Glass Pipe Insulation

Absorbs no moisture, so it’s immune to organic solvents, most acids, and corrosive environments. It's often used in chemical-processing systems and underground lines.

Slit Tubes

Ready to fit over straight pipe sections. Just pull open the insulation, snap it around your pipe, and seal it closed with the adhesive strip.

Jackets—An added defense against moisture for pipes in damp outdoor and underground environments. These metal jackets keep moisture from sneaking past, preventing corrosion and temperature loss.

Insulation Tapes—Wrap around pipe insulation for a tighter seal.
