Cellulose Insulation Services in Denver, CO
Eco-Friendly, High-Performance Insulation That Fills Every Gap
Sustainable. Powerful. And Perfect for Older Denver Homes.
If you’re looking for a smart, environmentally friendly way to reduce energy costs and improve home comfort, cellulose insulation may be the ideal choice.
At PIKA Insulation, we install professional-grade cellulose insulation throughout Denver, CO, helping homeowners upgrade efficiency, soundproofing, and air quality—all while using a product made from up to 85% recycled materials.
Whether you’re retrofitting an older home in Wash Park or insulating a new build in Sloan’s Lake, cellulose offers outstanding value and performance.
Cellulose vs. Fiberglass: What’s the Difference?
While both offer great R-values, here’s where cellulose shines:
| Feature | Cellulose | Fiberglass |
|---|---|---|
| Air sealing | Excellent | Limited |
| Soundproofing | Superior | Average |
| Eco-friendliness | Up to 85% recycled | Varies |
| Fire resistance | Borate treated | Non-combustible |
| Mold resistance | Yes | Yes (with proper air sealing) |
If you’re trying to insulate an older home, reduce noise, or make a green choice—cellulose often wins.
Attic Insulation – Your First Line of Defense Against Energy Loss
Your attic is responsible for the majority of your home's heat loss. We install high-performance attic insulation that:
Improves your R-value to meet or exceed Denver climate recommendations
- Prevents warm air from escaping during winter months
- Keeps your home cooler in the summer
- Lowers heating and cooling bills significantly
A properly insulated attic can cut your energy use by up to 20% annually—and we make sure it’s done right the first time.
Benefits of Cellulose Insulation in Denver Homes
High R-Value Performance
Cellulose delivers R-3.5 to R-4.0 per inch, comparable to fiberglass, with better real-world performance due to reduced air leakage.
Superior Air Sealing
Its dense structure slows air movement and heat transfer better than traditional insulation, making your home feel warmer in winter and cooler in summer.
Excellent Sound Control
Cellulose excels at absorbing sound, making it ideal for bedrooms, shared walls, and busy streets like Colfax or Federal Boulevard.
Fire Retardant
Treated with borate, cellulose offers fire resistance and helps slow the spread of flames—meeting modern building code requirements.
Pest & Mold Resistant
Borate treatments also deter insects and resist mold growth in damp or high-humidity conditions.
Environmentally Responsible
With up to 85% recycled content and low embodied energy, cellulose is one of the greenest insulation materials available today.

Our Cellulose Insulation Process
We’ve developed a clean, professional method for installing cellulose insulation in both existing homes and new construction.
Free Home Evaluation
We inspect your attic, walls, and framing to determine if cellulose is the right fit and where it can deliver the most impact.
Air Sealing (Optional but Recommended)
We identify and seal key leak points—around pipes, windows, and wiring—before insulating, which can boost performance by up to 30%.
Cellulose Installation
We use specialized blowers to apply cellulose with even density—whether loose-fill in attics or dense-pack in walls. This ensures there are no gaps, voids, or compressed areas.
Final Inspection & Clean-Up
We walk through the results with you, confirm performance with thermal tools or inspection, and leave your space spotless.
Perfect for Denver’s Historic Homes
Many homes in Denver’s older neighborhoods—like Capitol Hill, Park Hill, and Baker—have walls with little or no insulation.
Cellulose is a non-invasive solution:
● We drill small access holes from inside or outside
● Fill the cavity completely with dense-packed cellulose
● Seal the holes and restore the surface with minimal impact
There’s no need to tear out drywall or siding, making this an ideal option for preserving character while dramatically improving energy efficiency.
Is Cellulose Right for Your Project?
Cellulose insulation is an excellent fit if:
● You live in an older or under-insulated home
● You want to improve comfort and reduce energy bills
● You’re concerned about environmental impact
● You want to avoid a full demolition or remodel
● You need insulation with strong soundproofing properties
Our team can help assess whether cellulose is the best match—or recommend other materials that may suit your needs.
