Blown-In Insulation Pros in Boulder
Boulder’s high-altitude sun, chinook winds, and snowy winters can make your home feel uncomfortable and your heating system work overtime. The surprising part? A large share of homes here still rely on a thin, decades-old layer of attic insulation that falls well below current recommendations.
Best uses for blown-in insulation:
Attic floors, where a fresh layer quickly raises your R-value to today’s standards.
Wall cavities, in select retrofits, following industry best practices.
Knee walls & sloped ceilings where batts are tough to fit.
A Superior
The Thermal Blanket Effect
Upgrading with blown-in insulation is a fast, proven win for Boulder homeowners and businesses. The loose-fill blanket it forms over your attic floor or inside wall cavities delivers steady thermal performance through high-altitude sun and chinook winds, with quicker installation than most alternatives.
These capabilities define the insulation type:
Blocks Air Infiltration: When combined with Koala’s targeted air sealing, blown-in insulation helps reduce drafts by limiting the pathways where treated air can escape and outside air can sneak in around framing, wiring, and other penetrations common to homes in Boulder.
Stops Moisture: By improving overall attic R-value and supporting proper ventilation, blown-in insulation helps reduce the condensation and moisture movement that contribute to heat loss in homes in Boulder.
Advantages Of
Blown-In Insulation for Homes in Boulder
Between high-altitude sun and chinook winds, homes in Boulder work hard to stay comfortable. Blown-in insulation helps by installing quickly, topping off existing layers, and supporting lower energy costs with year-round comfort. Additional advantages include:
Improved Air Quality
Because our crews air-seal key attic leaks before blowing insulation, the upgrade also helps keep dust, pollen, and other outdoor pollutants from sneaking into the living spaces of your Boulder home through ceiling penetrations.
Water & Fire Resistance
The blown-in products we install are designed with fire safety in mind. Proper installation around recessed lights, chimneys, and other heat sources is critical, and our team follows local codes and manufacturer guidelines to help keep your Boulder home safe.
Pest and Wildlife Protection
Pest deterrence is a real, if lesser-known, benefit: cellulose blown-in insulation (uniquely among loose-fill options) is treated with compounds that discourage insect nesting, and air sealing the attic closes off the gaps pests use to get into homes in Boulder.
Soundproofing
Beyond temperature, there is peace and quiet. Loose-fill insulation absorbs airborne sound, taking the edge off busy roads, barking dogs, and the thump of upstairs rooms so your home in Boulder feels calmer.
Environmentally Friendly
Made largely from recycled materials, blown-in insulation is one of the greenest upgrades your Boulder home can get. It cuts the energy needed for heating and cooling (by up to 40% in some studies), lowering both utility bills and carbon footprint.
Our Straightforward 4-Step
Blown-In Insulation Process
Free Home Efficiency Assessment
The Koala Insulation efficiency experts will perform a thorough examination of the current efficiency of your Boulder home.
- Prep for Safe InstallationEvery blown-in insulation project in Boulder starts with careful preparation. We protect floors and walkways, set up safe access to the attic, and install rulers or depth markers so we can confirm the final insulation level across the entire space. If needed, we will install baffles at the eaves to maintain ventilation and keep insulation from blocking soffit vents.
Koala Difference: The payoff: insulation that performs as designed, and your Boulder home left exactly as clean as we found it.
- Seal Key Leaks & Set Up EquipmentBefore blowing in insulation, our team addresses the air leaks common to homes in Boulder: plumbing penetrations, wiring, recessed lights, attic access points, and other leaks detected by our thermography leak detection system.
Koala Difference: Pairing air sealing with the blow-in is how we turn a good upgrade into a great one for your Boulder home.
- Blow In & Level the InsulationThen comes the main event: loose-fill is blown across the attic to the target depth and R-value. Corners, eaves, and the hard-to-reach pockets typical of homes in Boulder get deliberate attention, and we keep verifying against the depth markers until the whole space reads level.
Koala Difference: Coverage is everything. We take the time to verify depth and consistency so your Boulder home is not left with “thin spots” that reduce performance.
- Cleanup, Photos & Walkthrough
Once the target depth is confirmed, we vacuum the work area, pack out all equipment, and verify the attic access is sealed tight. Then we walk you through the project at your Boulder home, share before-and-after photos when available, and answer any questions about your new insulation.
Koala Difference: Our job does not end when the blower shuts off. Koala Insulation of Boulder is here for future questions, and to help you take advantage of any available rebates or tax credits.

What Does Blown-In Insulation Cost in Boulder?
Blown-in insulation is one of the more affordable ways to upgrade home comfort, and the final investment comes down to a handful of factors.
The biggest factors include:
- The size of your home: More attic square footage means more material and more installation time.
- The type of insulation used: Materials like cellulose and fiberglass are priced differently.
- The level of effort involved: Attic access, prep work, air sealing, and any old insulation removal all shape the scope.
The good news is that the investment pays you back through steadier comfort and lower heating and cooling costs season after season.
Rebates from state and local governments and from many utilities can also help take a bite out of the total, and our team can point you toward what may be available. Every home in Boulder is unique. For an accurate estimate tailored to your property and goals, contact the team today to schedule a free assessment.
Is Blown-In Insulation Better Than Rolls (Batts)?
For attics, blown-in usually wins. Loose-fill flows around joists, wiring, and pipes to form one continuous blanket, while rolls (batts) tend to leave small gaps at edges and obstructions. In attics in Boulder, those little gaps add up to drafts, uneven rooms, and performance below the rating on the package.
How Much Blown-In Insulation Do I Need?
The right amount comes down to three inputs: the square footage of the space, the insulation depth required, and where you live (see the map below). Climate drives the recommended attic R-value, with colder regions needing thicker insulation to slow heat loss and warmer regions needing enough depth to block heat gain. Attic size and target R-value together set how much material consistent coverage requires. Boulder falls in IECC Climate Zone 5B (cold), where DOE and ENERGY STAR guidance calls for attic insulation of roughly R-38 to R-60.
That is why professional installers do not eyeball it: material calculations follow climate-zone guidelines, current insulation levels, and manufacturer coverage charts. Done right, the depth matches the recommended R-value for your area, allows for natural settling, and leaves no thin spots to drag down performance. The diagram below illustrates how recommended attic insulation levels shift by region, a quick way to see why needs differ from one location to the next.
