Top Insulation Materials Used in Denver, CO

In order to determine the right insulation solutions for your home, it’s important to understand the properties, pros and cons, and applications of various materials commonly used in Denver attic insulation projects:


Made from 80% recycled paper/cardboard waste, cellulose is among the most affordable and sustainable blown-in insulation options. With an R-value of R-3.7 per inch, it excels at reducing air infiltration while allowing any moisture to readily evaporate. It is best for standard attic insulation projects.

Proper installation density is 3.5-4.0 lbs per sq. ft to prevent settling. We exclusively use modern cellulose forms treated with safe fire retardants for maximum stability and performance.


Fiberglass insulation comes in blanket (batts) or loose-fill variations. Spun from recycled glass and sand, it delivers an R-Value of roughly R-3 per inch with moderate cost. For blown-in uses, dense packing is required to minimize settling and air gaps over time.

Fiberglass loses R-Value if exposed to moisture and requires additional safety equipment during installation to prevent skin, eye, and respiratory irritation. These factors lead many Denver homeowners to opt for cellulose instead.

Rock Wool

Rock wool, also called mineral wool, uses natural stone and recycled material to create non-combustible, fire-resistant blown-in insulation. With an R-Value of R-3 to R-4.5 per inch, it adds solid thermal and acoustic insulation.

As rock wool is denser than cellulose or fiberglass, the attic needs extra load-bearing reinforcement. It also carries higher material expenses for most homeowners compared to the alternatives.

Average R-Value Recommended in Denver, CO

The optimal attic R-Value recommended for most Denver homes is R-49 to R-60. Our energy audits and insulation expertise align with the latest 2021 IECC building code guidance for your local climate zone.

We evaluate the unique specifications of your attic space and discuss your budget to recommend the right R-Value to:

Rest assured our blown-in insulation solutions consistently reach long-term, stable Rs exceeding code minimums for superior efficiency over traditional materials.
