Build, upgrade and repair your HVAC systems with 3M duct tape & other UL 723 standard products from Hisco

Fire resistance standards measure the performance of various constructions, including materials for HVAC manufacturing for fire containment purposes.

The UL 723 Surface Burning Characteristic of Building Materials test is a standard of Underwriters Laboratories (UL) that measures building materials' burning properties or fire resistance in the case of exposure to flames. Code officials use the results from this test to accept materials for HVAC manufacturing.

Hisco carries a comprehensive portfolio of HVAC solutions that complaint with UL 723 standards for fire resistance and performance, including foams, gaskets, insulation, sealants, and tapes.
