Top Insulation Contractor in Boulder

Spray Foam is a two-part product that is heated and then is sent through a hose into the stud cavity, where it hardens in a matter of seconds and creates a long-term barrier that keeps your home comfortable and energy efficient.

Consisting of small pieces of insulation, this type of insulation can quite literally fill every nook and cranny of a space and create an uber-fluffy layer of effective insulation. Our technicians ensure your attic, wall and ceiling cavities are filled correctly and without gaps or voids.

Koala Insulation of Boulder is an insulation removal company serving Boulder and the Front Range. We remove insulation that is contaminated by rodents, soaked, smoke damaged, or degraded past the point of working. Then we clean and treat the space, air seal it, and install new insulation to your jurisdiction's requirement.

One of the most recognizable forms of insulation. Batt comes in large rolls or pre-cut sections that are typically pink or yellow in color. These are installed in sheet form and laid out between the studs in walls, floors, and attics.

Solar attic fans turn your attic into a livable space by pushing hot air out and pulling cool air in. Our fans use solar energy to keep your attic at a comfortable temperature year-round.

We identify and seal leaks letting air in and out of your home to reduce unwanted temperature loss or gain.

Keep your crawl space dry and your floors warm with vapor barrier crawl space insulation that helps you save energy.

Koala Insulation of Boulder works Boulder County, Jefferson County and the communities west and north of Denver. Boulder, Longmont, Lafayette, Louisville, Superior, Erie, Broomfield, Westminster, Arvada, Golden and Lakewood, plus the foothills and mountain properties beyond them.
That territory covers close to a century and a half of housing stock. Late 1800s homes in the original town cores of Boulder, Golden and Longmont. Brick ranches, split levels and mid century designs built across Lakewood, Arvada and Westminster in the post war decades. Multi story subdivisions that filled in Broomfield and Lafayette during the US 36 tech corridor build out. And the master planned neighborhoods of Erie, almost all of it built after 2000.
Different eras, different framing, different failure points. A 1962 ranch with a shallow attic and a boxed in whole house fan is a different job than a 2006 two story with disconnected attic sections, and both are different from a 1910 Boulder home with an addition off the back and a dirt crawl space underneath.
What does not change is the standard. Air sealing before insulation. Baffles at every eave. The attic hatch treated as part of the building envelope. Ventilation balanced rather than ignored. Insulation installed to the level your jurisdiction requires, at even depth, with enough depth gauges that you can verify it yourself.
Most companies will add five inches on top of what you have and leave. That is not what we do, and it is why our customers stop calling insulation companies after us.
