Many older duct systems are made of metal, which naturally oxidizes over time. This oxidation leads to dust buildup inside the ducts, lowering air quality and circulating unwanted particles throughout your home. In homes with flat roofs, the ductwork is often installed overhead, which can result in air leaks due to improper installation. Without proper sealing, air escapes, leading to poor system efficiency. To make sure your ducts are fully sealed and functioning optimally, it's crucial to address these issues with a specialized solution.
Duct Armor™ is the solution. Our innovative system restores your air ducts by completely sealing them from the inside with a synthetic latex and rubber coating. This product fills all cracks and crevices, ensuring better airflow, increased system efficiency, and, ultimately, a healthier, more comfortable home.
