Where does your attic actually stand?
Even depth across the entire attic floor is what actually delivers R-value, a thin patch above a Broomfield Heights split-level stairwell or a wind-scoured corner facing Big Dry Creek can undercut the whole attic’s performance. Zone 5B’s target of R-49 to R-60 is tough to reach with insulation that’s settled since these homes were built decades ago.

01THE PROBLEM
The Attic Problems Blown-In Insulation Quietly Solves.
Broomfield Heights’ Cold War-era ranches and split-levels were built to the insulation standards of their time, which fall well short of today’s targets, while some Anthem new builds still only carry builder-minimum coverage. Front Range wind coming across the Big Dry Creek corridor makes any gap in the attic worse. In nearly every case it’s not the furnace struggling, it’s under-depth, settled, or gappy loose-fill combined with unsealed air leaks around can lights, ductwork, and the attic hatch.
A · Attics still sitting at an old R-19 to R-30
Bonus rooms and home offices framed above an attached garage sit over unconditioned space, so heat drains through the floor while the garage pulls it away below. You get cold floors, a room running 10–15° off the rest of the house, and a furnace that never catches up. We insulate the floor joists, knee walls, and sloped ceilings, then air-seal the garage ceiling and rim.
B · Loose-fill that has settled, thinned, or gone flat
Most Broomfield basements, the brick ranches east of Wadsworth, the split-levels around Lake Arbor, have bare concrete or block foundation walls. Finishing that basement without insulating the walls first buys you a cold, clammy room and a heating bill to match. Blown-Ins in the new stud walls, with the correct vapor retarder, turn it into comfortable, usable square footage.
C · Bare patches, gaps, and wind-washed eaves
Additions, pop-tops, and finished attic conversions are often framed to the minimum of their day, or never insulated in the walls at all. That leaves one part of the house always chasing the thermostat. Filling the wall, floor, and rafter cavities with properly sized blown-in insulation brings the new space up to the same comfort as the original home.
D · Ice dams and a top floor that never holds heat
Insulation isn’t only about temperature. Blown-Ins packed into interior walls and between floors cut the sound that travels between a media room and the bedrooms, an office and the living room, or upstairs and down. Mineral wool does this best. It’s a small add during a remodel that quietly changes how the whole house feels.
02THE FIX
Cellulose or Fiberglass. One Honest Recommendation.
We start with an in-person attic inspection to measure real depth and find air leaks, not a guess from the hatch. Air-sealing and eave baffles go in first, then we recommend cellulose for dense, borate-treated coverage, common in older Broomfield Heights attics, or fiberglass where settling resistance matters more, one honest call either way.
03WHAT TO EXPECT
A Half-Day Inside. Here's How It Goes.
A typical Broomfield blown-in attic job runs from inspection through air-sealing to a final depth-check, usually wrapped up in a few hours whether it’s a Broomfield Heights split-level or an Anthem two-story.
We confirm the plan from your assessment, then protect floors and finishes around the work area.
We air-seal top plates, can lights, and the attic hatch, then set baffles at the eaves so airflow cannot wind-wash the new insulation.
Loose-fill is machine-blown evenly across the attic floor to the marked depth, filling every gap around joists, ducts, and penetrations.
We check coverage against depth-ruler cards staked across the attic so you hit the rated R-value corner to corner.
We vacuum up, haul away offcuts, and walk every cavity with you before we leave.

★ ★ ★ ★ ★
Our split-level in Broomfield Heights had a second floor that felt ten degrees hotter than downstairs every summer, and we'd get ice dams along the north eave most winters. Grizzly sealed the attic bypasses around our old bathroom fan vent and topped everything off to full depth, and this past winter the ice dams just didn't happen. Our heating bill in January was noticeably lower than the year before.

Blown-in insulation is loose-fill cellulose or fiberglass machine-blown into the attic to a measured, even depth. In Broomfield it’s used across attic floors in both Cold War-era Broomfield Heights homes and newer Anthem builds, filling gaps and topping off insulation that’s thinned or settled.
Both perform well installed correctly. Cellulose’s dense, borate-treated coverage suits the older, irregular framing common in Broomfield Heights attics, while fiberglass resists settling and tolerates moisture well, which can be a better fit in newer Anthem construction. We’ll recommend one specific to what we find in your attic.
Yes, in most Broomfield attics we blow new insulation directly over existing material as long as it’s dry and in reasonable shape, which is common in Broomfield Heights homes where the original insulation has simply settled over 60-plus years. If there’s soiling or water damage, that portion gets removed first.
Broomfield sits in Climate Zone 5B, calling for R-49 to R-60 in the attic, about 14 to 17 inches of cellulose or 16 to 20 inches of fiberglass depending on the product. We measure actual depth throughout the attic, since Broomfield Heights homes especially tend to have uneven coverage after decades.
Cellulose settles somewhat after installation, and we account for that during installation so you still land at your target depth. Front Range wind near Big Dry Creek can also wind-wash loose-fill from the eaves over time if the attic lacks proper baffles, which is why air-sealing and baffles matter as much as the material itself.
Blown-in wins in Broomfield attics with irregular framing or existing insulation to top off, true of both Broomfield Heights and Anthem homes. Batts fit open wall cavities better than attic floors. Spray foam suits complex rooflines or conditioned attics, but for a standard vented attic, blown-in reaches R-49–R-60 for less.
