USG Corporation has earned GreenGuard Gold certification for more than 200 low-emitting products through the UL Environment program.
The GreenGuard Certification program, part of the UL Environment business unit of Underwriters Laboratories, requires compliance to stringent emissions standards that are broadly recognized and accepted by sustainable building programs and building codes around the world. GreenGuard certification helps consumers choose building materials with lower VOC emissions, which improves indoor air quality.
