What is a Thermal Barrier?

A thermal barrier is a material applied between spray foam insulation and the interior living space. This layer plays a crucial role in enhancing safety, primarily by acting as a fire resistance measure. The International Residential Code (IRC) mandates this barrier to protect occupants from potential fire hazards associated with insulation materials.

Not every area in your home requires a thermal barrier. This decision largely depends on the location of the spray foam and the potential risks involved.

  • Why is a Thermal Barrier Important?

    The primary function of a thermal barrier is to provide fire resistance. In the past, spray foam insulations were viewed as flammable or a fire hazard. However, it's important to note that building codes have been somewhat slow in updating their standards to reflect the advancements in spray foam technology. Many high-quality spray foam insulations now boast a Class One Fire Rating, meaning they don’t significantly contribute to fire spread.

  • When is a Thermal Barrier Needed?

    Deciding when a thermal barrier is necessary can be confusing. The key is to understand the fire risk associated with the location of the spray foam. Generally, spaces that are more integrated into your living area will require a thermal barrier for added safety. However, some areas, like certain non-living spaces or storage areas, may not require it, depending on local codes and the specific installation scenario.
