An ignition barrier is a fire-safety material or coating applied over combustible insulation, such as spray foam, to delay ignition and slow fire spread. It is commonly required in attics or crawl spaces where insulation is exposed. Proper ignition barriers help meet building codes and improve occupant safety.

Ignition barriers reduce fire risk in concealed spaces.
In an attic with spray foam insulation, an ignition barrier coating is applied to meet code and reduce fire risk.
Always verify local code requirements before installing insulation or barrier materials.
“Always verify local code requirements before installing insulation or barrier materials.”
Thermal barriers provide a higher level of fire protection than ignition barriers.
Is an ignition barrier always required?
Requirements vary by code and location, especially for exposed insulation.
What is the difference between ignition and thermal barriers?
Thermal barriers provide higher fire resistance and are required in occupied spaces.
Can I install an ignition barrier myself?
It’s best to use a professional to ensure compliance and correct coverage.
