When it comes to home insulation, one of the most common materials used is foam board insulation. It is an excellent choice due to its durability, flexibility, and ability to provide excellent thermal insulation. However, concerns about its flammability often arise, and many people wonder if foam board insulation is flammable.
The short answer is yes, foam board insulation can be flammable. However, the flammability of foam board insulation varies depending on the type of foam material it is made from and the specific fire hazards it is exposed to.

The Different Types of Foam Board Insulation
There are different types of foam board insulation available in the market, including:
- Polyisocyanurate (Polyiso): Polyiso foam board insulation is known for its high insulation R-values. It is made from closed-cell foam and is often used in commercial and residential construction.
- Expanded Polystyrene (EPS): EPS foam board insulation is composed of small foam beads and is known for its excellent thermal insulation properties. It is commonly used for insulation in walls, roofs, and foundations.
- Extruded Polystyrene (XPS): XPS foam board insulation is denser and more water-resistant compared to EPS. It is often used in below-grade foundation walls and other areas where moisture is present.
Factors Affecting Flammability
The flammability of foam board insulation can be influenced by several factors, including:
- Fire Retardants: Foam board insulation can be treated with fire retardants to reduce its flammability. Fire-retardant treatments can help improve the fire-resistant properties of foam board insulation and slow down the spread of flames.
- Thickness: Thicker foam board insulation typically has a higher density and may be more difficult to ignite compared to thinner insulation boards.
- Installation: Proper installation of foam board insulation is crucial to minimize potential fire hazards. Gaps, voids, or improper installation techniques can create pathways for fire to spread.
- Surrounding Materials: The flammability of foam board insulation can also be influenced by the materials it is in contact with. If exposed to highly flammable materials, such as untreated wood or gas pipes, the risk of fire can increase.

Fire Safety Measures
While foam board insulation can be flammable, proper fire safety measures can significantly reduce the risk of fire:
- Keep Open Flames Away: Avoid placing foam board insulation near open flames, such as gas stoves, fireplaces, or candles. This reduces the likelihood of accidental ignition.
- Use Fire-Resistant Barrier: Installing a fire-resistant barrier such as drywall over foam board insulation can help contain a fire and prevent its spread.
- Follow Building Codes: Adhere to local building codes and regulations when installing foam board insulation. These codes often provide guidelines for fire safety and insulation requirements.
- Regular Inspections: Regularly inspect and maintain your foam board insulation to ensure there are no damages, cracks, or gaps that could compromise its fire resistance.
- Consult Professionals: If you have concerns about the fire safety of foam board insulation, consult with professionals who have expertise in insulation installation and fire safety.
