INSULATION COMPANY ARVADA, CO
Insulation Built for Lafayette, From Old Town to Indian Peaks
Lafayette grew up as a coal-mining town, and its housing tells that story. Old Town holds compact early-1900s miners’ cottages — often with almost no insulation to begin with — while newer neighborhoods like Indian Peaks, Coal Creek, and around Waneka Lake were built to 1990s–2000s code minimums. Each era needs a different fix.
Sitting in Boulder County at the edge of the foothills, Lafayette also sees strong Front Range wind and — as the December 2021 Marshall Fire made painfully clear — real wildland-fire exposure just to the west. 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 Lafayette 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 80026.

Click any service below for the dedicated Lafayette page with full details, process, and neighborhood context:
Blown-in and batt upgrades to R-49–R-60 — from near-zero Old Town cottages to code-minimum Indian Peaks homes. Most attics done in a day.
Closed-cell air-barrier foam for rim joists, additions, and the wind-exposed assemblies of Lafayette’s older and newer homes alike.
Sealing the ceiling plane against Front Range wind before insulation — because in a leaky coal-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 Lafayette’s older cottages and Coal Creek-corridor foundations.
EPA-registered TAP® borate insulation adds thermal performance and rodent deterrence in one install — built for open-space-adjacent Lafayette homes.
Spray foam and fiberglass systems for Old Town’s Public Road storefronts, offices, and light-industrial space — off-hours, on schedule.

WHY LOCAL EXPERTISE MATTERS
Lafayette's Insulation Challenges
Three local realities shape how we quote, prep, and install every Lafayette job — from coal-era cottages to open-space wildlife.
From Coal-Era Cottages to New Subdivisions
Lafayette’s homes span the coal era to today. Old Town’s miners’ cottages often have empty wall cavities and next to no attic insulation; the 1990s–2000s builds in Indian Peaks and Coal 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
Lafayette sits at the edge of the foothills, 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
Coal Creek, Waneka Lake, and the open space around Lafayette 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 Old Town 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 Lafayette, answered straight.
Lafayette is in Climate Zone 5B, where attics should carry R-49 to R-60 — roughly 16–20 inches of blown-in insulation. Old Town cottages often measure near zero; even 1990s Indian Peaks homes measure R-19 or less. A free assessment shows exactly where you stand.
Almost always — the coal-era cottages 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. Coal Creek, Waneka Lake, and Lafayette’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 Lafayette projects combine both.
Often, yes. Lafayette 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 Lafayette 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, Old Town Lafayette to Indian Peaks, 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.
