I am presently working on all major building codes. Problem I am running into with some is they are trying to put me in a classification as Canister Foams and Great Stuff etc. To do so and win approval Home Depot, Lowes etc would have to do same. We want the approvals in full, not just meeting criteria.
We pass an E 84 with a 15 Minute Fire Barrier at present so the Fire Barrier has the burden. We are presently conducting teststs on both a No Flame No Smoke Plural instant set that sprays from our same gun and plan to incorporate this technoligy very soon into our SoyThane. We however will still insist on a 15 minute Fire Barrier such as Sheet Rock.
