Cellulose insulation delivers more than just R-value. It combines thermal performance, sound control, and eco-friendly materials to make your home quieter, safer, and more energy efficient.
At Thermo Shield, we install Sanctuary® cellulose insulation from Greenfiber® — engineered to create healthier, more comfortable living environments.
Made from 85% recycled paper and treated for fire resistance, cellulose is one of the most sustainable and cost-effective insulation choices for Arizona homeowners.
Cellulose isn’t just for attics — it can also be dense-packed into wall cavities to improve comfort and efficiency throughout your home. By filling every gap and seam, wall insulation helps eliminate drafts, reduce noise, and stabilize indoor temperatures.
Garage Walls
Adding blown-in insulation to garage walls reduces hot and cold spots, lightens your HVAC workload, and helps your system run more quietly and efficiently. It can also lower utility bills, shrink your carbon footprint, and may even qualify for rebates or tax credits — while boosting resale value with year-round comfort.
Interior Walls
Dense-packed cellulose also works as a sound barrier, cutting noise between rooms and from the outdoors. Small drilled holes are used to inject insulation, then patched and sealed, allowing most homes to be upgraded in just a day or two with minimal disruption.
R-value measures resistance to heat flow — the higher the R-value, the better the insulation.
Cellulose insulation typically lasts 20–30 years. With proper installation and regular inspections, it provides decades of comfort, efficiency, and peace of mind.
Nearly 90% of Arizona homes are under-insulated, leading to higher bills and less comfort. Signs your home may need more insulation:
