INSULATION COMPANY ARVADA, CO
Insulation Built for Aurora, From Original Aurora to Southshore
Aurora boomed after WWII around Fitzsimons into Colorado’s third-largest city. Original Aurora holds compact WWII-era bungalows — often with almost no insulation to begin with — while newer neighborhoods like Southshore, Toll Gate Creek, and around Aurora Reservoir were built to 1990s–2000s code minimums. Each era needs a different fix.
Sitting in Arapahoe County on the eastern plains of the metro, Aurora also sees strong Front Range wind, hard freeze-thaw swings, and the wind and hail the eastern metro is known for. A tight, well-insulated envelope is about comfort, efficiency, and resilience all at once.
Colorado sits in IECC Climate Zone 5B, which calls for R-49 to R-60 in the attic. Many older Aurora homes we inspect measure R-19 or less — and the oldest measure close to zero. Grizzly handles every service on this page for homeowners across 80010.

Click any service below for the dedicated Aurora page with full details, process, and neighborhood context:
Blown-in and batt upgrades to R-49–R-60 — from near-zero Original Aurora cottages to code-minimum Southshore homes. Most attics done in a day.
Closed-cell air-barrier foam for rim joists, additions, and the wind-exposed assemblies of Aurora’s older and newer homes alike.
Sealing the ceiling plane against Front Range wind before insulation — because in a leaky wartime-era cottage, air sealing is where the savings start.
HEPA-filtered removal of old, settled, or rodent-soiled material — clean deck, healthier air, disposal handled, ready for a proper reset.
Moisture-smart crawl space insulation and encapsulation for Aurora’s older cottages and Toll Gate Creek-corridor foundations.
EPA-registered TAP® borate insulation adds thermal performance and rodent deterrence in one install — built for open-space-adjacent Aurora homes.
Spray foam and fiberglass systems for Original Aurora’s Havana Street storefronts, offices, and light-industrial space — off-hours, on schedule.

WHY LOCAL EXPERTISE MATTERS
Aurora's Insulation Challenges
Three local realities shape how we quote, prep, and install every Aurora job — from bungalows to open-space wildlife.
From Older Homes to New Subdivisions
Aurora’s homes span the wartime-era to today. Original Aurora’s bungalows often have empty wall cavities and next to no attic insulation; the 1990s–2000s builds in Southshore and Toll Gate Creek carry code-minimum R-19. Each needs its own fix — dense-pack, top-off, or a full removal and reset.
Front Range Climate Extremes
Aurora sits on the eastern plains of the metro, where temperatures swing sharply and Front Range wind pushes cold air through every gap. Freeze-thaw cycling works openings loose around can lights, flues, and framing. Insulation without air sealing simply can’t keep up here.
Open Space = Rodent Pressure
Toll Gate Creek, Aurora Reservoir, and the open space around Aurora funnel mice toward warm attics every fall. Rodent-soiled insulation loses R-value and hurts air quality. We handle removal, exclusion, and borate-treated pest-control insulation in-house.

What Homeowners Say About Grizzly
★ ★ ★ ★ ★
We kept hearing scratching in the attic every October, and the upstairs bedrooms never held heat. Grizzly’s crew vacuumed out sixty years of filthy insulation, sealed the entry gaps, and blew in the pest-control insulation, all in one day. Two winters later: no mice, warmer bedrooms, and our January Xcel bill dropped noticeably.

“Our Original Aurora cottage had almost no insulation and a furnace that never caught up. Grizzly dense-packed the walls, air-sealed the attic, and brought it to R-49. Warm for the first time in years — and the bills dropped fast.”

Frequently Asked Questions
Common questions about insulation in Aurora, answered straight.
Aurora is in Climate Zone 5B, where attics should carry R-49 to R-60 — roughly 16–20 inches of blown-in insulation. Original Aurora cottages often measure near zero; even 1990s Southshore homes measure R-19 or less. A free assessment shows exactly where you stand.
Almost always — the bungalows have the most to gain because they started with so little. We often dense-pack the empty walls and air-seal first, then top the attic to R-49+. Degraded or rodent-soiled material comes out before new goes in.
Yes, in-house. Toll Gate Creek, Aurora Reservoir, and Aurora’s open space put homes near steady rodent pressure. We remove soiled insulation with HEPA vacuums, seal the entry points, and install borate insulation that resists nesting.
They solve different problems. Blown-in cellulose is the cost-effective choice for open attic floors where R-49+ is the target. Spray foam delivers the highest R-value per inch and doubles as an air barrier, ideal for rim joists, crawl spaces, and garages. Many Aurora projects combine both.
Often, yes. Aurora is in Xcel Energy territory, and qualifying insulation and air-sealing work can earn utility rebates, plus the federal 25C tax credit covers 30% of qualifying costs up to $1,200/year. Programs change, so we confirm current eligibility during your free estimate and help with documentation.
Most single-family projects finish in 1–2 days. An attic top-off with air sealing on a typical Aurora ranch is often a single day. Whole-home projects touching the crawl space and rim joists may run two full days. You get a clear timeline with your quote, and we stick to it.
All of them, Original Aurora to Southshore, ZIP codes 80002, 80003, 80004, 80005, and 80007. Our crew is based in Commerce City, about 20 minutes away via I-76, and we offer free estimates across the entire city and Jefferson County.
