New 2 hour re-occupancy and 1 hour re-entry times announced by Icynene
Icynene today introduced revised shorter re-entry and re-occupancy allowances for trades and homeowners in the United States for its ultra-low VOC Icynene Classic Max and Icynene ProSeal spray foam products. The revised allowances permit one hour re-entry for trades and two hour re-occupancy for homeowners.
The revised re-entry and re-occupancy allowances follow months of extensive research, testing and third-party evaluation of the two ultra-low -VOC spray foam products based on protocols and procedures developed by a task group of the American Chemistry Council – Center for the Polyurethanes Industry (ACC-CPI).
“Full scale testing and research evaluated by credible third party chemists and toxicologists has confirmed that re-entry and re-occupancy times can be further reduced to one hour and two hours respectively. Ultra-low VOC Icynene Classic Max and Icynene ProSeal spray foam, combined with the use of higher workplace ventilation rates of 40 Air Changes per Hour (ACH), have helped us reduce exposure risks to spray foam installers, to non-spray foam trades and, most especially, to homeowners and their families,” said Icynene VP Engineering, Paul Duffy.
The revised re-entry and re-occupancy allowances are only applicable for installations of Icynene Classic Max and Icynene ProSeal in the United States and are based on an active ventilation rate of 40.0 ACH.
