About Duct Armor

A material known as transite was used for in-slab ductwork until the 1980’s. Transite was the trade name for concrete, which used asbestos as the bonding agent. As air systems go through normal wear and tear, these asbestos fibers have become friable and then airborne, posing a risk to anyone exposed. 

Prior to Duct Armor, solutions were limited for ductwork that posed a health risk or was deteriorating. The alternatives are expensive and create construction zones that take weeks or even months to complete. One approach is to tear out the ductwork and replace it, sometimes cutting out floors or walls. The other is to completely fill and seal off in-ground ducts with concrete, before installing new ductwork in the walls and ceiling, and potentially a new furnace.

Recognizing the need for a cost effective and environmentally friendly method that restores and repairs ductwork, led to the creation of Duct Armor. The coating is a proprietary water-based latex material. Duct Armor is safe for children or pets, and has been rigorously tested and EPA approved to encapsulate asbestos and contains zinc to inhibit mold growth without the use of poisons, off-gassing or VOC’s.

Duct Armor non-invasive encapsulation is the safe and easy way to restore ductwork and air quality in your home or business, avoiding the chaos and costs of renovation projects. Remodeling your home and the relocation of air ducts into the attic, including purchasing a new furnace is no longer necessary.
