Industrial insulation jacket for high-temperature

The Unitherm IW1824 is a silicone-coated fiberglass jacket designed for straight pipe sections in industrial environments. It fits circumferences between 6 and 13 inches and uses a quick-release fabric flap with wiretwists for secure fastening. The 18 by 24 inch cover provides a 3 inch thick insulation layer.

Thermal performance up to 900 degrees Fahrenheit

The fiberglass and mineral wool insulation withstands a maximum ambient temperature of 900 degrees F while maintaining an R-value of .48. The gray silicone-coated cloth jacket resists heat transfer and protects surrounding equipment and personnel. This construction meets OSHA standards for industrial applications.

Sustained heat containment for continuous operations

Under prolonged exposure the jacket maintains its insulating properties without degradation of the fiberglass core or mineral wool fill. The quick-release fastening system allows repeated removal and reinstallation for inspection cycles. It is not suited for pipes exceeding the 13 inch maximum circumference or for curved fitting geometries.

Questions about this item

How do I install the quick-release fabric flap and wiretwists on the 18 in by 24 in jacket?

Wrap the silicone-coated fiberglass cloth around the pipe, align the fabric flap, press the hook-and-loop closure firmly, then tighten each wiretwist by twisting until the 3 in thick insulation sits snug against the surface.

What maintenance does the fiberglass and mineral wool insulation need after exposure to 900 Degrees F?

Inspect the gray silicone-coated cloth for tears or wiretwist corrosion after each high-heat cycle; replace the jacket if the insulation material shows compression or moisture damage.

At what point does the R 0.48 value stop limiting heat loss on a continuous 900 Degrees F run?

The 0.48 R-value provides minimal resistance; surface temperature will approach the 900 Degrees F ambient limit quickly, so the jacket’s insulation thickness becomes the limiting factor during sustained operation.
