A commonly asked question is, "do I need a 15-Minute Thermal Barrier over exposed spray foam?" More often than not, the answer is yes. To help our answer we should look at the purpose of a thermal barrier. A 15-minute thermal barrier over spray foam is designed to provide 15 minutes of fire protection before a constant flame hitting cured spray foam creates smoke. This allows the occupants of a burning building time to escape in a more safe manner. The two most common products to use are fire-rated drywall and intumescent paint.
Another common question is, "but most closed cell foams and some open cell foams have a built-in ignition barrier, is that enough to leave those spray foam exposed?" By code, probably not but it depends on the area. A 15-minute thermal barrier will be required over exposed foam in any attic or crawlspaces that could potentially be used for storage. It doesn’t matter if you’re fitting 100 boxes or a shoebox, if it can be used for storage a thermal barrier will be required. The only exception where spray foam with a built-in ignition barrier may be left exposed is when the attic or crawlspace has access only for the service of utilities and mechanicals. Keep in mind that your local building official has the final determination.
