Thermaflex flexible duct has been awarded GREENGUARD Certification by the GREENGUARD Environmental Institute (GEI). To earn certification Thermaflex products went through a series of rigorous emissions test to confirm the level of volatile organic chemicals (VOC) emitted. These tests proved positive in enabling Thermaflex to gain certification by the GREENGUARD Certification Program, the only independent program for low emitting-products.
