Welcome to Koala Insulation of Boulder

We are a Boulder-based insulation company serving homeowners, builders, and commercial clients across Boulder County, Jefferson County, and the communities west and north of Denver.

Our team runs 5+ crews and carries three certified BPI analysts on staff, which means the person assessing your home understands it as a complete system rather than as a place to put insulation. That shows up in the work. More than 340 homeowners have left us a five-star review, and most of them worked with someone named on this page.

Between our operations and sales teams, we have decades of insulation experience specifically, not general home services experience applied to insulation. We think that distinction matters, and we think you will notice it on the estimate.

Mar runs material procurement, scheduling, quality control, and the customer-facing side of production. He brings more than ten years in trades operations, dispatching and scheduling across as many as fifteen crews at once. If your job is on the calendar and moving, Mar is the reason.
