Duct insulation falls off as result of condensation and corrosion under insulation. Rust is produced by condensation and moisture inside insulating materials. Condensation occurs when the amount of moisture in the air is higher than the volume of air can absorb. This is usually caused by the cooling of warm, humid air, so excess moisture condenses on the wall of the duct. Condensation starts when you have more than 10°C difference between inside and outside of the duct.
By reduction of the surface temperature by 38%, the difference between inside and outside of the duct is close, ThermaCote eliminates the condensation, reduces humidity and prevents the rust on the HVAC-ducts. Too it reduces maintenance costs and eliminates radiant heat from hot ducts. In addition, ThermaCote maintains the temperature inside by controlling heat losses. Furthermore, the elimination of fiberglass reduces the size of space needed for installation. ThermaCote is approved by the European Cool Roof Council. It increases the insulation and solar reflection; hence it protects and extends the lifetime of your roof and their equipment.
