When To Spray An Ignition Barrier?
If a home has spray foam insulation in an attic or crawl space, the building code requires using materials or assemblies that offer some fire resistance but not as much as is required for a thermal barrier. If you have spray foam insulation in an attic, for example, it’s probably already separated from the living space by a thermal barrier. Most ceilings are made of 1/2″ drywall. But the spray foam is still exposed to the attic and needs an ignition barrier.
