Will it work on duct board?
We find that the duct board deteriorates over time and the black outer fabric liner breaks down and will cause fine black particles to be released into the air system. We coat this outer lining and it will encase the outer fabric and stop the release of particle debris. However, please note that due to the construction of duct board, it can only penetrate the outer layer; it does not make it to the metal structure since there is a fiberglass layer between the fabric top layer and the metal structure.
Will it work on flex systems?
Duct Armor can be applied to all shapes of air duct work since it’s a spray on application.
Duct Armor comes with a 15 year warranty.
What Are My Air Ducts Made Of?
The majority of ductwork in the United States is made of rolled or galvanized steel, Transite (asbestos & cement), or sonotube.
What is Transite and Why Is It a Problem?
After 30 to 65 years of being subjected to the hot and cold blowing air through them, the Transite cement has experienced some level of deterioration. You might see this as a fine, white power-like substance in the ducts or around the floor vents.
What should I do if I have In-Ground, Transite Air Ducts?
Disclaimer: Duct Armor is biased on this one! Encapsulating your in-floor air ducts is simple, takes just a few hours, and maintains the efficiencies of your original air distribution system.
But you do need to evaluate your options. Abandoning the transite ductwork would require some or all of the following over a period of days, weeks, or months: 1) Filling the existing ducts with cement; 2) Purchasing a new, updraft furnace; 3) Permits; 4) Deconstructing walls and ceilings in order to run the new ductwork through your house; 5) Putting your house back together and painting…everything. Beware the temptation to put the new supply vents and the return vents at the ceiling level: This could lead to huge energy bills because most of the conditioned air never reaches the floor level. And if you settle for the lower cost flexduct option, you may be impeding air flow, thus increasing energy costs. Flexduct can also introduce more carcinogens into your home because of its fiberglass insulation which is usually protected with just a thin plastic barrier. (fiberglass is a carcinogen)
What is Sonotube?
A thick gauged cardboard with a foil lining that was used for in-floor ducting in some construction from the early 1970’s to the mid 1980’s. The problems with these systems all results from water: High water table, bad drainage away from the house, or humidity/moisture damage over many years from within the HVAC system. When the cardboard starts to deteriorate, air flow is impeded and allergens are released into your home or office space.

Is Mold in Air Ducts a Problem?
When mold spores get into our homes, they can settle in the air conditioning system and ductwork along with dust and other contaminants. Air ducts, especially during the humid months, can be virtual incubators for microbial pollutants such as mold and bacteria. With the alternating high and low humidity conditions which regularly occur in our air conditioning ducts during normal operation, mold will produce spores and distribute them throughout the house. Natural humidity levels as well as the installation of humidifiers into our HVAC systems both contribute to this problem.
What Are The Signs That I Might Have Mold In My House Or Building?
In addition to allergens, molds may emit microbiological volatile organic compounds (MVOC’s). These chemicals usually have a strong and unpleasant odor and are associated with the musty smell that many individuals equate to mold being present. These chemicals are released into the air and when inhaled, can also cause allergic reactions. MVOC’s have also been linked to headaches, nausea, dizziness and fatigue.
Some molds may produce toxic substances called mycotoxins. Mycotoxins can be inhaled, ingested or absorbed through the skin. Mycotoxins are potent, toxic chemicals that can cause significant health problems. Different molds may product different mycotoxins depending on the surface on which they are growing. Mycotoxins can affect the central nervous system, the immune system, the respiratory system and the digestive system. Some molds may cause more severe reactions than other molds, so it is important that mold be remediated. For any severe exposures or health effects associated with a mold exposure, individuals should consult their physician.
