About Selecting Thermal Insulation

Compare R-value and temperature range to find the insulation material that best suits your application.

Fiberglass Pipe Insulation

When foam can't handle the heat, go with fiberglass insulation. It withstands temperatures hundreds of degrees hotter than rubber or polyethylene foam, so it's often used on hot water supply and steam lines.

Slit Tubes

Kraft Paper Jacket

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.

Kraft Paper Jacket— A lightweight jacket shields insulation from dust, minor scratches, and wear during handling.

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

Flame-Resistant Mineral Wool Pipe Insulation

Keep flames from spreading along process piping. Made of mineral wool and to ASTM E84 0/0 standards, this insulation won't catch fire or give off smoke. It also maintains its shape and strength at temperatures up to 1200° F without melting or shrinking.

Slit Tubes

Ready to fit over straight pipe sections. Just pull open the insulation, snap it around your pipe, and seal it closed with contact adhesives or insulation tape (not included).
