PGAL’s design team specified acoustic stone wool ceiling panels and metal ceiling suspension systems. Helping them make informed decisions about material ingredients, the ceiling system manufacturer also offered health product declarations (HPDs), and UL-certified environmental product declarations (EPDs).
These low-emitting products contribute to healthy indoor air quality. Stone wool products are available as UL Environment’s GREENGUARD Gold certified for low volatile organic compounds (VOCs) emitting materials in offices, as well as other spaces (i.e schools). This stringent certification is recognized by numerous green building and wellness programs, including LEED.
“The Indoor Air Quality [IAQ] and VOCs were another non-negotiable LEED credit to achieve that this ceiling product complimented,” says Bass. He also noted that the GREENGUARD certification also played a crucial role in meeting LEED materials and resources category credits.
Sourced from abundant basalt rock, stone wool naturally resists the growth of mold, mildew, and potentially harmful microorganisms, without the use of added antimicrobials, biocides, or fungicides. The stone wool ceiling panels include no fire-retardant chemicals and achieve Class A fire performance. Both the stone wool ceiling panels and its metal suspension systems are made with recycled content. At the end of their life on the building, the suspension systems are also 100 percent recyclable.
The stone wool ceiling panels on Grundfos’ new regional headquarters require minimal maintenance throughout their long lifecycle and are backed by a 30-year warranty.
“Ceiling resiliency, like all finishes, is a critical feature to ensure the best long-term investment,” says Bass.
