Cellulose Safety FAQ: Is Cellulose Insulation Safe?

Compared to other insulation materials, does cellulose insulation make a safe choice for your home or building? Understanding cellulose safety is crucial for occupant well-being and environmental sustainability is crucial when deciding between insulation materials.


So, let’s delve into the key aspects of cellulose safety! By addressing concerns about flammability, chemicals, and air quality, we’ll help you make the best possible choice for your next construction project.

Flammability: Is Cellulose Insulation Fire-Resistant?

Fire resistance is one of the most essential qualities in an insulation material. That’s why Tropical Insulation offers cellulose insulation treated with boric acid. Cellulose insulation exhibits excellent fire resistance due to its fire retardant treatment, which enhances its resistance to ignition and flame spread.


Unlike other materials, cellulose has slow-burning properties, smouldering rather than igniting, which reduces fire risks and ensures better containment in case of a fire incident. Rest assured, cellulose insulation meets or exceeds industry fire safety standards, providing peace of mind to homeowners and building occupants.

Chemical Safety

You may wonder how cellulose, an organic material, compares to other, often toxic, insulation materials. Cellulose insulation is derived from recycled paper and has minimal chemical content. It is a natural and non-toxic material, making it safe for your home or building.


Rigorous testing and certifications ensure that cellulose insulation complies with health and safety regulations, guaranteeing a safe environment for all. Moreover, cellulose insulation promotes healthy indoor air quality by minimizing the release of volatile organic compounds (VOCs) and other harmful substances.

Air Quality & Cellulose Safety

Cellulose insulation plays a significant role in improving indoor air quality and occupant well-being. Its effective air sealing creates a tight barrier, reducing air leakage and preventing the infiltration of pollutants. The moisture regulation properties of cellulose insulation help prevent mould and mildew growth, maintaining a healthy and comfortable indoor environment. Additionally, cellulose’s acoustic properties contribute to a quieter living or working space, enhancing overall comfort and well-being.

Quick Air Quality & Cellulose Safety Facts



  • Moisture Regulation: Cellulose’s ability to regulate moisture prevents the buildup of mould and mildew. Damp and mouldy environments can lead to respiratory issues and other health problems. With cellulose insulation, you can rest easy knowing that your indoor spaces are protected against moisture-related concerns.
  • Reduction of Airborne Allergens: Unlike some other insulation materials, cellulose does not release harmful fibres or particles into the air. This means that you and your family can breathe easier, free from potential allergens that might be present in other insulation options.
  • Thermal Insulation Benefits: In addition to promoting excellent indoor air quality, cellulose insulation also offers outstanding thermal performance. It helps maintain a consistent indoor temperature, keeping your home warm in the winter and cool in the summer.
  • Energy Efficiency Improvements: By providing superior insulation, cellulose helps reduce energy consumption. This not only saves you money on utility bills but also contributes to a greener, more environmentally sustainable living space.

With these benefits, it’s clear that cellulose insulation not only ensures a safe living environment but also enhances your overall comfort and well-being. Say goodbye to drafts, moisture issues, and unwanted noise while enjoying improved air quality and energy efficiency in your home or building. Now, let’s compare cellulose insulation to other commonly used insulation materials to make an informed choice.

Comparing Insulation Materials & Cellulose Safety 

Now, let’s compare cellulose insulation to other popular insulation materials. Fibreglass insulation may be commonly used, but it lacks the fire resistance and chemical safety that cellulose offers. And when it comes to spray foam insulation, cellulose stands out with its environmentally friendly attributes and minimal health concerns. Furthermore, cellulose insulation provides excellent thermal performance and soundproofing capabilities, making it a top choice for homeowners and contractors alike.
