Cellulose vs Fiberglass for Blown Insulation in Ottawa: Which is Right for Your Home?
When it comes to blown-in insulation in Ottawa , homeowners often debate between cellulose and fiberglass. Both materials offer unique benefits, but understanding their differences is key to maximizing energy efficiency, cost-effectiveness, and comfort. Let’s break down the pros and cons of each, with insights tailored to Ottawa’s climate.
Cost Comparison: Affordability Meets Performance
Cellulose insulation is often praised for its eco-friendly composition of recycled paper fibers. While both materials are similarly priced (around $1.5 – $1.6 per sq. ft), fiberglass is typically less expensive upfront. However, cellulose’s higher R-value (thermal resistance) can lead to long-term savings by reducing heating costs in Ottawa’s cold winters.
Verdict: Fiberglass wins for budget-friendly projects, but cellulose offers better ROI through energy efficiency.
R-Value Showdown: Insulation Power
Cellulose boasts a higher R-value per inch (R-3.2 to R-3.8) compared to fiberglass (R-2.2 to R-4.3, depending on density). This makes cellulose more effective at trapping heat, a critical factor for Ottawa homes facing harsh winters. Fiberglass, however, is quicker to install and resists moisture, making it ideal for damp-prone areas.
Verdict: Cellulose for superior thermal performance; fiberglass for moisture resistance.
Eco-Friendliness & Safety
Cellulose is the eco-champion, composed of 80% recycled materials, while fiberglass requires more energy-intensive production. Both are fire-resistant, but cellulose’s borate treatment adds protection against pests and mold. Fiberglass, however, does not absorb water, reducing risks in humid climates.
Verdict: Choose cellulose for sustainability; fiberglass for moisture-prone spaces.

FAQs Cellulose vs Fiberglass
1. Which is better for Ottawa’s climate: cellulose or fiberglass insulation?
Answer: Cellulose is ideal for Ottawa’s harsh winters due to its higher R-value (R-3.2–3.8), providing superior thermal performance. Fiberglass (R-2.2–4.3) is better for moisture-prone areas but may require thicker installation to match cellulose’s efficiency.
2. How do costs compare between cellulose and fiberglass?
Answer: Both materials cost $1.5 – $1.6 per sq. ft. upfront, but cellulose offers long-term savings via higher energy efficiency. Fiberglass is slightly cheaper initially but may cost more over time due to lower R-value.
3. Is cellulose insulation eco-friendlier than fiberglass?
Answer: Yes. Cellulose is made from 80% recycled materials, while fiberglass production is more energy-intensive. Both are fire-resistant, but cellulose also resists pests and mold with borate treatments.
4. Can I install blown-in insulation over existing fiberglass?
Answer: Yes! Cellulose can be blown over existing fiberglass insulation, provided the fiberglass is dry and undamaged. This boosts R-value without removing old material.
5. Does fiberglass insulation resist moisture better?
Answer: Fiberglass is naturally moisture-resistant, making it suitable for damp areas like basements. Cellulose requires borate treatments to prevent mold/mildew but still outperforms fiberglass in thermal efficiency.
6. How long do cellulose and fiberglass insulation last?
Answer: Cellulose lasts 20–30 years, while fiberglass can endure 25–50 years with proper installation. Both degrade faster if exposed to moisture or pests.
7. Should I hire a professional for blown-in insulation?
Answer: Yes. Professional installation ensures optimal coverage and air sealing, critical for Ottawa’s climate. MUS Energy Solutions specializes in custom, airtight installations and conducts blower door tests for quality.
8. Can I combine cellulose and fiberglass insulation?
Answer: Yes, cellulose can be layered over fiberglass to enhance R-value without compatibility issues. Consult MUS Energy Solutions to design a hybrid solution for your home.
9. What’s the difference in installation time?
Answer: Fiberglass is quicker to install due to its lightweight nature. Cellulose requires specialized equipment but fills gaps more effectively, reducing air leaks.
10. Are there alternatives to blown-in insulation?
Answer: Spray foam insulation offers unmatched air sealing and R-value (R-6–7 per inch) but is pricier. MUS Energy Solutions provides spray foam as a premium option for Ottawa homes.
