ACFoam-III and ACFoam-IV Now GreenGuard Listed for Mold Resistance

Atlas Polyiso Products Also Screened for VOC and Formaldehyde Emissions


October 29th, 2010

Recent testing at Air Quality Sciences has resulted in a clean bill of health for ACFoam-III and ACFoam-IV, as well as our coated-glass faced side-wall sheathing products. These products received the GREENGUARD Environmental Institute’s highest rating of 4--Highly Resistant to Mold Growth--yet another sign of Atlas’s commitment to a healthy environment. This GREENGUARD test method is conducted in accordance with ASTM D 6329 and rates materials for susceptibility for microbial growth. The test was conducted on whole products, not just the facing material. After inoculating the product with Penicillium Brevicompactum, the laboratory technician transfers it to an environmental chamber and checks for mold growth, ranking the product on a basis of 1 (highly susceptible to mold growth) to 4 (highly resistant to mold growth).

Additionally, a recent screening test at Air Quality Sciences, an accredited IAQ (Indoor Air Quality) testing lab, has resulted in another clean bill of health for Atlas’s polyiso roof insulation products, as well as side-wall sheathing products. The products were screened for TVOC, formaldehyde and total aldehyde emissions. In every case, the emissions reported were below the maximum emission levels allowed under both the GREENGUARD and GREENGUARD Schools and Children criteria, an even more rigorous emission standard. Based on this screening report, ACFoam-II was chosen for the full GREENGUARD and GREENGUARD Schools and Children test protocol. For both of these standards, the emissions remained below the maximum allowable, indicating that Atlas’s polyiso insulation products are considered very low emitting products, one more assurance of Atlas’s commitment to a healthy built environment. Since some recent inquiries by LEED consultants have interpreted roof insulation as subject to Indoor Air Quality requirements for LEED credits, this recent testing should provide additional value when you are asked about product emissions of VOCs or formaldehyde.
