Up to 50% energy savings compared to traditional insulation
Airtight seal — 25x less air-permeable than other insulation types
Closed-cell spray foam adds structural rigidity and moisture resistance
Open-cell spray foam provides excellent soundproofing
No settling, sagging, or degradation over time
Meets Denver Climate Zone 5 energy code requirements (R-38 to R-60)
A proven, methodical approach refined over 20+ years of professional installation.
We assess your property, discuss your insulation goals, and provide a clear, upfront estimate — no hidden fees or obligations.
Our crew prepares the installation area by masking off surfaces, ensuring proper ventilation, and setting up containment as needed.
Spray foam is applied to the specified thickness using calibrated equipment, expanding to fill every gap and cavity for a seamless thermal envelope.
We verify proper coverage and thickness, trim excess foam as needed, and leave your space clean and ready for finishing.
Spray foam insulation is the premier choice for residential and commercial properties in Denver, Colorado, delivering superior thermal performance, air sealing, and moisture resistance in a single application. Unlike traditional insulation methods, spray foam expands on contact to fill every gap, crack, and cavity — creating a seamless, airtight barrier that dramatically reduces energy loss. With R-values as high as R-6.5 per inch for closed-cell spray foam, it is one of the most efficient insulation materials available for Denver's demanding Climate Zone 5 requirements. At Sky Insulation, our certified spray foam installers bring over two decades of hands-on experience to every project. Whether you need open-cell spray foam for interior soundproofing and moisture management, or closed-cell spray foam for maximum thermal resistance and structural reinforcement, we tailor the application to your building's specific needs. From attic and crawl space insulation to wall cavities and rim joists, spray foam provides unmatched performance for Denver homes and businesses facing extreme temperature swings, high winds, and dry winter air. Denver homeowners and commercial property managers trust Sky Insulation for spray foam applications because we combine industry-leading products with factory-certified installation techniques. Properly installed spray foam insulation can reduce energy costs by up to 50% compared to traditional insulation, while also adding structural rigidity to walls and rooflines.
Closed-cell spray foam delivers R-6.5 per inch — the highest R-value of any insulation material, cutting heating and cooling costs dramatically.
Spray foam expands to fill every gap and crack, eliminating drafts and cold spots that account for up to 40% of energy loss in Denver homes.
Closed-cell spray foam acts as a vapor barrier, preventing moisture intrusion and mold growth in Denver's freeze-thaw climate.
Spray foam insulation maintains its R-value for the life of the building — no settling, compressing, or degrading over time.
Open-cell spray foam (R-3.7 per inch) is lighter, more flexible, and ideal for interior applications, soundproofing, and moisture management. Closed-cell spray foam (R-6.5 per inch) is denser, provides a vapor barrier, adds structural strength, and is ideal for exterior walls, crawl spaces, and areas exposed to moisture.
Most Denver homeowners see energy savings of 30–50% after spray foam installation, depending on the existing insulation condition and the areas treated. The airtight seal eliminates drafts and reduces the workload on your HVAC system year-round.
Yes. Once cured (typically within 24 hours), spray foam insulation is inert and safe. Our certified installers follow all safety protocols during application, including proper ventilation and containment procedures.
Spray foam insulation is designed to last the lifetime of the building. Unlike fiberglass or cellulose, it does not settle, sag, or degrade over time, maintaining its R-value and air-sealing properties indefinitely.
Yes. Open-cell spray foam is especially effective at reducing airborne sound transmission, making it a popular choice for media rooms, bedrooms, and shared walls in multi-family buildings.
The most impactful areas for spray foam insulation are attics (roof deck), crawl spaces, rim joists, basement walls, and exterior wall cavities. Our team will assess your property and recommend the best approach for maximum energy savings.
