Corrosion Guarantee

NU-WOOL Premium Cellulose Insulation is warranted for all the test items currently in effect for insulation materials under ASTM Standard C 739. Included in this standard is a test for corrosion resistance.

NU-WOOL Co. Inc. warrants its insulation product, when properly installed, to be corrosion resistant to all types of metal for the life of the structure. NU-WOOL Co. Inc. has offered, since 1978, a full lifetime warranty for their products. That warranty clearly lists each test characteristic, including corrosion.

NU-WOOL Co. Inc. specifically warrants those test characteristics to metal buildings properly insulated with NU-WOOL Premium Cellulose Insulation.
