Insulation VS Flamethrower: Is Insulation Flammable

Hey folks, it’s TJ from Sanctified Homes, back with another hands-on test that’s all about keeping your home safe and making informed choices. Today, we're putting different types of insulation to the ultimate test against a flamethrower to see which one holds up best. Safety is paramount in construction, and choosing the right insulation is crucial not just for comfort and energy efficiency but for fire resistance too. We're testing rock wool, fiberglass ("bad insulation"), and foam board insulation to see how they react under extreme heat. This isn’t just about seeing which materials burn; it’s about understanding how they protect—or fail to protect—your home in the event of a fire.

Understanding Different Insulation Materials

Rock Wool Insulation

Rock wool, made from mineral fibers, is known for its fire-resistant qualities. In our tests, when exposed to extreme heat, rock wool's ability to resist burning was impressive. Even when the gas from the flamethrower initially caught fire on the surface, the insulation itself did not sustain the flame. This material is not only fire-resistant but also durable against pests, making it a top choice for both urban and rural settings. For more on why rock wool might be the right choice for your home, check out our detailed guide here.

Fiberglass Insulation

Fiberglass, commonly referred to by TJ as "bad insulation" during the test, initially resisted the flame but eventually caught fire, continuing to burn even after the gas had burned off. This highlights a significant risk in terms of fire safety, as the material can contribute to fire spread within a home. While it’s a popular insulation choice due to its cost-effectiveness and sound-dampening properties, its performance in a fire scenario can be a concern.

Foam Board Insulation

Foam board did the poorest in our fire resistance test. It not only caught fire quickly but also melted into a sticky, oozy substance, releasing potentially harmful chemicals. The rapid degradation of this material in high heat and its contribution to toxic smoke can be incredibly dangerous during a fire, posing serious risks to both property and personal safety.

Choosing the Right Insulation for Fire Safety

Selecting the right insulation is more than just about thermal ratings and energy efficiency; it's also about considering how materials react in a fire. Our tests show that rock wool stands out as the safest option among the three, with significant resistance to fire without compromising on insulative properties or pest resistance.

When building or renovating your home, consider the fire safety aspect of every material you choose. It's not just a matter of compliance or comfort but a critical component of your home's safety strategy. Always consult with a building professional who can provide insights based on the latest research and product performances.

Conclusion: Safety First in Insulation Choice

The results from our flamethrower test are clear: not all insulation is created equal, especially when it comes to fire resistance. As homeowners, it's crucial to look beyond the surface benefits of materials like cost savings and consider the long-term implications, particularly safety. Opting for materials like rock wool can significantly enhance your home's resilience against fire, offering peace of mind that other materials simply can't match.
