TECHLITE 379 Series insulation is a heavy duty insulation developed for demanding environments. High abuse and harsh U.V. conditions are no problem for the 379 Series.

The 379 Series uses a high strength, flexible PVC/fabric composite exterior jacket that is permanently laminated to the TECHLITE foam. The jacket is a UV stabilized, flexible PVC reinforced with polyester fibers providing exceptional strength and tear resistance while remaining flexible; enabling it to be impacted and return to its original shape while retaining its vapor barrier.

TECHLITE 379 Series is available as pipe insulation, flat sheet, and v-grooved sheets to wrap ducts, tanks, and large storage vessels.

In addition, several colors are available from the factory eliminating the need to paint after installing.
