We evaluate your current insulation, identify problem areas, and recommend the best blown-in or batt solution for your property and budget.
Choose from fiberglass, cellulose, or mineral wool based on your performance needs, fire resistance requirements, and budget.
Our crews install insulation to proper density and coverage specifications, ensuring no gaps, voids, or compressed areas that reduce performance.
We verify R-value coverage, check for complete fill in all cavities, and clean up the work area — leaving your space ready for use.
Blown-in and batt insulation are two of the most versatile and cost-effective insulation solutions for Denver homes and commercial buildings. Blown-in insulation — available in fiberglass and cellulose — is installed using specialized equipment that densely packs material into wall cavities, attic floors, and hard-to-reach spaces, creating a tight thermal envelope that minimizes air infiltration. Batt insulation, made from fiberglass or mineral wool, provides reliable thermal resistance when installed in open wall stud cavities, floor joists, and ceiling assemblies. Sky Insulation specializes in both blown-in and batt insulation installation for new construction, renovations, and energy-efficiency upgrades across the Denver metro area. Our experienced crews assess each project to determine the ideal insulation strategy — whether that means dense-pack cellulose in existing wall cavities, loose-fill fiberglass blown over attic floors, or mineral wool batts for fire resistance and soundproofing. We ensure proper coverage, consistent R-values, and no gaps or voids that compromise performance. For Denver homeowners looking to improve comfort and reduce energy bills without the cost of spray foam, blown-in and batt insulation deliver exceptional value. Properly installed blown-in insulation achieves 15–20% annual energy cost reductions, while batt insulation provides a straightforward thermal barrier for standard framing assemblies.

Blown-in and batt insulation deliver strong thermal performance at a lower cost than spray foam — ideal for budget-conscious energy upgrades.
From open attic floors to enclosed wall cavities and irregular spaces, these insulation types adapt to virtually any building geometry.
Mineral wool batts offer inherent fire resistance without chemical treatments, providing added safety for your home or business.
Blown-in insulation can be installed quickly using specialized equipment, minimizing disruption to your home or business operations.






Blown-in insulation is loose material (fiberglass or cellulose) installed with a blowing machine, ideal for filling irregular cavities and covering existing insulation. Batt insulation comes in pre-cut rolls or sheets (fiberglass or mineral wool) sized to fit standard stud and joist spacing.
Each has advantages. Fiberglass is affordable and moisture-resistant. Cellulose is made from recycled material and provides excellent air infiltration reduction. Mineral wool offers superior fire resistance and soundproofing. We help you choose based on your goals and budget.
Yes — blown-in insulation is commonly added on top of existing attic insulation to boost R-values to current energy code standards. This is one of the most cost-effective home energy upgrades available.
Denver falls in Climate Zone 5, which requires R-38 to R-60 in attic spaces per current energy codes. Most older Denver homes have significantly less than this, making attic insulation upgrades one of the highest-ROI improvements.
Fiberglass blown-in insulation lasts 20–30 years or more when properly installed and maintained. Cellulose can settle slightly over time but remains effective for 15–20 years. We install to density specifications that account for normal settling.
