What is Cellulose Insulation? Cellulose insulation is a loose-fill, eco-friendly material made from 85% recycled newspaper treated with natural fire retardants. At Eco-Therma, we use Igloo Cellulose™—a high-quality, biosourced product engineered for superior thermal and acoustic performance.
Cellulose can be installed in attics, walls, ceilings, and floors using methods like blown-in, dense-pack, and stabilized spray. It offers a tighter fit than fiberglass, effectively sealing cracks and reducing air leakage.
Key Benefits of Cellulose Insulation
1. Superior Thermal Performance
Cellulose has an R-value of approximately 3.8 per inch and a phase-shift delay of up to 10 hours, meaning it keeps your home cooler in the summer and warmer in the winter. Compared to fiberglass, it performs better in real-life conditions.
2. Acoustic Comfort
The dense fiber structure absorbs airborne sounds, making cellulose ideal for homes near busy streets or noisy neighborhoods in the GTA.
3. Moisture Regulation & Mold Resistance
Cellulose is hygroscopic—it can absorb and release moisture without promoting mold. This helps regulate humidity and maintain a healthier indoor environment.
4. Eco-Friendly & SafeMade from recycled materials and requiring low energy to manufacture, Igloo Cellulose is GREENGUARD Gold certified. Borate treatments also provide natural fire, mold, and pest resistance.
5. Long-Lasting & Gap-Free
Cellulose naturally conforms to irregular spaces around pipes and wires, reducing drafts and thermal bridging. It resists settling when installed correctly and has a life expectancy of over 75 years.
Where is Cellulose Best Installed?
Area | Method | Benefit |
