INSULATION COMPANY ARVADA, CO

Insulation Built for Broomfield, From Broomfield Heights to Anthem

Broomfield grew from 1950s Broomfield Heights, built for Rocky Flats and aerospace workers, into master-planned communities. Broomfield Heights holds compact 1950s Cold War-era ranches — often with almost no insulation to begin with — while newer neighborhoods like Anthem, Big Dry Creek, and around Great Western Reservoir were built to 1990s–2000s code minimums. Each era needs a different fix.

Sitting in Broomfield County on the plateau between Denver and Boulder, Broomfield also sees strong Front Range wind, hard freeze-thaw swings, and the hail this corridor 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 Broomfield 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 80020.

Blown-in and batt upgrades to R-49–R-60 — from near-zero Broomfield Heights cottages to code-minimum Anthem homes. Most attics done in a day.

Closed-cell air-barrier foam for rim joists, additions, and the wind-exposed assemblies of Broomfield’s older and newer homes alike.

Sealing the ceiling plane against Front Range wind before insulation — because in a leaky midcentury 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 Broomfield’s older cottages and Big Dry Creek-corridor foundations.

EPA-registered TAP® borate insulation adds thermal performance and rodent deterrence in one install — built for open-space-adjacent Broomfield homes.

Spray foam and fiberglass systems for Broomfield Heights’s Midway Boulevard storefronts, offices, and light-industrial space — off-hours, on schedule.

WHY LOCAL EXPERTISE MATTERS

Broomfield's Insulation Challenges

Three local realities shape how we quote, prep, and install every Broomfield job — from Cold War-era ranches to open-space wildlife.

HOUSING STOCK

From Older Homes to New Subdivisions

Broomfield’s homes span the midcentury to today. Broomfield Heights’s Cold War-era ranches often have empty wall cavities and next to no attic insulation; the 1990s–2000s builds in Anthem and Big Dry Creek carry code-minimum R-19. Each needs its own fix — dense-pack, top-off, or a full removal and reset.

CLIMATE EXTREMES

Front Range Climate Extremes

Broomfield sits on the plateau between Denver and Boulder, 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.

RODENT PRESSURE

Open Space = Rodent Pressure

Big Dry Creek, Great Western Reservoir, and the open space around Broomfield 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 Broomfield Heights 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 Broomfield, answered straight.

Broomfield is in Climate Zone 5B, where attics should carry R-49 to R-60 — roughly 16–20 inches of blown-in insulation. Broomfield Heights cottages often measure near zero; even 1990s Anthem homes measure R-19 or less. A free assessment shows exactly where you stand.

Almost always — the Cold War-era ranches 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. Big Dry Creek, Great Western Reservoir, and Broomfield’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 Broomfield projects combine both.

Often, yes. Broomfield 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 Broomfield 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.
