Where does your attic actually stand?
Attic R-value isn’t a number on a bag, it’s a function of even depth and full coverage across every square foot of the attic floor; a wind-blown corner or a settled ridge line drags the whole home’s performance down. In Climate Zone 5B, Grizzly targets R-49 to R-60 for Highlands Ranch attics, which typically means 14 to 17 inches of properly settled cellulose or fiberglass loose-fill.

01THE PROBLEM
The Attic Problems Blown-In Insulation Quietly Solves.
Highlands Ranch’s 1980s-to-2000s master-planned two-stories were built fast and built similarly, and their attics show it: builder-grade insulation blown in decades ago has settled, shifted, and thinned out over the years, especially near hips, valleys, and soffits. Add in Front Range’s wide day-night temperature swings and intense summer sun on those upper-floor bedrooms, and you get rooms that never quite catch up to the thermostat. In neighborhoods like Northridge, Westridge, and Firelight, the pattern is almost always the same, under-depth insulation and unsealed attic penetrations, not an undersized furnace or AC. Chasing it with HVAC alone just burns money on a problem that starts above the ceiling drywall.
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 Highlands Ranch 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 every Highlands Ranch attic with a real inspection, checking existing depth, moisture, and where air is leaking around can lights, top plates, and the attic hatch. We air-seal those gaps and set fresh eave baffles so soffit vents keep working once new insulation goes in, then recommend either dense-packed, borate-treated cellulose or moisture-tolerant fiberglass that won’t settle, based on what your attic actually needs, not a one-size-fits-all pitch.
03WHAT TO EXPECT
A Half-Day Inside. Here's How It Goes.
A typical Highlands Ranch blown-in job starts with a walk-through and attic inspection, moves into air-sealing and baffle work, then the blow itself, and wraps up with a depth-check across the whole attic floor. Most homes are done in a few hours, start to finish.
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.
The Grizzly 100% Guarantee
If the work isn't right, we make it right. That's the reputation we've built across the Front Range, and it's our only sales pitch.
04COST & SAVINGS
What Blown-In Insulation Costs in Highlands Ranch
No two Highlands Ranch attics price out the same. What moves the number is attic square footage, how deep we need to go to hit your target R-value, how much air-sealing the attic needs, and whether old, soiled or matted insulation has to come out first. You’ll get an itemized quote before we blow a single pound of material.

★ ★ ★ ★ ★
Our upstairs bedrooms in Westridge used to be unusable by July, the AC just couldn't keep up. Grizzly found almost no insulation over one whole section of the attic where it had settled against the trusses. After they air-sealed and topped it off, that floor finally feels like the rest of the house.

Blown-in insulation is loose-fill cellulose or fiberglass that’s machine-blown across your attic floor to a measured depth, filling every gap, corner, and joist bay evenly. It’s used specifically in attics, not walls, which is where batt or spray foam insulation typically goes, because it can conform to irregular framing and obstacles like wiring and ductwork without leaving gaps.
Both perform well in Highlands Ranch attics; the right choice depends on your specific attic. Cellulose is dense-packed and borate-treated, giving it a slight edge for air-sealing tight spaces and resisting pests, while fiberglass won’t settle over time and handles occasional moisture better. We inspect your attic first and give you one honest recommendation instead of pushing whichever material we happen to have on the truck.
Yes, in most Highlands Ranch attics we blow new insulation directly over existing material, as long as it’s dry and not compacted, contaminated, or moldy. If the old insulation is soiled, matted, or damaged, we’ll recommend removing it first so the new material can perform the way it’s supposed to.
In Climate Zone 5B, which covers Highlands Ranch and the rest of the Front Range, the target is R-49 to R-60 in the attic. Depending on the material, that generally works out to roughly 14 to 17 inches of properly installed, evenly distributed loose-fill across the entire attic floor.
All loose-fill insulation settles somewhat over its first year, which is exactly why we install to a depth that accounts for expected settling and why older Highlands Ranch attics often measure thinner than they were originally installed. Wind-washing near soffits and disturbed insulation from attic storage or repairs can also thin coverage faster than normal aging alone.
Blown-in wins in attics with irregular framing, existing insulation to top off, or lots of wiring and ductwork to work around, which describes most Highlands Ranch attics. Batts make more sense in open wall cavities or new construction where precise panel fit is practical, and spray foam earns its higher cost in unvented or complex roof assemblies where an air-and-vapor barrier is the goal, not just R-value.
