Questions about InsulStar Plus Hurricane Foam Adhesive: "Does InsulStar Plus meet the requirements of local building codes?" Yes, (Florida Product Approval #9975. ~Tom
"Can I save money on my home owners insurance hurricane policy?" Yes, it is considered a deck reinforcement and a S.W.R (secondary water resistance). ~Tom
"What is a S.W.R?" It's an additional roof protection system in the event you lose your shingles and water has the possibility of coming in the attic. ~Tom
"What is Deck Reinforcement?" Most likely, your existing roof decking is only secured by nails. InsulStar Plus adheres the plywood decking directly to the trusses, making it 3 times stronger than code requires. ~Tom
"How do you apply this?" We spray the hurricane foam adhesive in your attic up against the roof deck. There are 3 levels of protection we can spray. The first level is called fillets, which is sprayed where the rafters meet the sheathing and where the joints come together in the decking. This level will give you the insurance discounts for the deck reinforcement and secondary water barrier, but will not give you insulation value. The second level is to spray 1" of foam under the entire roof deck. That will give you a R-value of 6.8. The third level is 2" of spray to give you a R-value of 13.6. Of course the higher the R-value the greater the protection from the outside air. But this also makes your decking much stronger and the 1" spray will cover most of the nail holes. ~Tom
