We now use SES Spray Foam which passes 377 appendix x uncoated (ignition barrier not required). This new high bio-based content 0.5/lb product contains over 15% bio-based content in the finished foam. This is extremely high – most polyurethane foam products cannot achieve this value in the resin let alone the finished foam. Our values were obtained from ASTM-6886.
SES Foam’s 0.5/lb product is a true polyurethane with the high insulating properties you expect from polyurethanes including air sealing capabilities with high flow rates to ensure every nook and cranny are closed to provide you with an extremely tight building envelope.
