✅ Pros of Wet-Blown Cellulose Insulation
1. Excellent Air Sealing
• Fills cavities completely, reducing air leaks better than batts or loose-fill.
• Helps maintain consistent indoor temperatures.
2. High Thermal Performance
• R-value of ~R-3.6 to R-3.8 per inch — higher than fiberglass batts.
• Densely packed to reduce thermal bridging and heat loss.
3. Superior Soundproofing
• The dense fiber structure helps block sound transmission through walls.
• Ideal for interior walls, home theaters, or multifamily housing.
4. Environmentally Friendly
• Made from up to 85% recycled newspaper.
• Has a low carbon footprint and minimal environmental impact.
5. Fire Resistant
• Treated with borate-based fire retardants that resist ignition and slow flame spread.
6. Pest and Mold Resistant
• Borates also act as a natural pest repellent (against insects and rodents) and resist mold growth (if properly dried).
7. Custom Fit to Cavities
• Wet-blown cellulose adheres to surfaces, conforming around wires, pipes, and framing — no gaps or voids.
8. Less Settling Than Loose-Fill
• The adhesive mixture helps prevent settling over time, maintaining insulation performance.
