The Thermaflex® M-KC flexible duct has been awarded GREENGUARD Certification by the GREENGUARD Environmental Institute (GEI). To earn certification M-KC went through a series of rigorous emissions tests for levels of total particles, formaldehyde, and other volatile organic compounds (VOCs). Independent testing has also confirmed that M-KC does not support the growth of mold or mildew. M-KC also undergoes quarterly monitoring tests to provide ongoing assurance of low emitting status.
The GREENGUARD Certification Program is the only independent testing program for low-emitting products. It helps builders, architects, interior designers, specifying professionals, and consumers create better indoor environments, by providing a free online guide to scientifically tested low emitting products.
