New-Construction Insulation in Boulder, CO
Whole-home insulation and air-barrier packages for builders and custom homes — engineered to pass Boulder's energy code and perform for decades.
Building or remodeling in Boulder County means building to some of the most demanding energy codes in the country — and the insulation and air-barrier system is at the heart of meeting them. We partner with builders, general contractors, and homeowners on new-construction and major-remodel projects to design and install a complete insulation package that passes inspection, hits performance targets, and delivers the comfort a new home should have.
Insulating during construction, while the framing is open, is the ideal time to get everything right: the best materials in the right places, a continuous air barrier, and the details that are impossible to fix later. We bring the products, the crews, and the code knowledge to make that happen on schedule.
Why homeowners choose it
- Engineered to meet Boulder County energy code
- Whole-home system: foam, blown-in, and batt where each fits
- Continuous air barrier detailed while framing is open
- Coordinated with your build schedule and inspections
- High-performance envelope for lasting comfort and low bills
- One accountable insulation partner for the whole project
A whole-home system, not just one product
The best-performing new homes don't rely on a single insulation type — they use the right product in each location. We commonly specify closed-cell spray foam at rim joists and problem areas for its air seal and moisture control, blown-in or batts in the walls, and a deep blown-in blanket in the attic, all tied together with a continuous air barrier. Designing the system as a whole is how you hit aggressive energy targets efficiently rather than overspending on foam everywhere.
- Closed-cell foam at rim joists and critical air-seal areas
- Blown-in or batt in wall cavities
- Deep blown-in attic blanket to code R-value
- Continuous air barrier tying it all together
Meeting Boulder's energy code
Boulder and Boulder County enforce advanced energy codes that go beyond the baseline, with requirements for insulation levels, air-tightness (verified by blower-door testing), and sometimes whole-home energy performance. We build to those requirements and coordinate the blower-door and inspection steps so your project passes the first time. Knowing the code — and how inspectors verify it locally — keeps your build on schedule and avoids costly rework.
On schedule, coordinated with your trades
On a job site, insulation timing matters. We coordinate closely with framing, electrical, plumbing, and drywall so we're in and out at the right moment, the air barrier is detailed before it's covered, and inspections line up. Builders work with us because we show up when scheduled, install to spec, and keep the project moving. For homeowners running their own build, we bring that same reliability and translate the code requirements into a system that simply performs.
Ideal for
- Custom and spec home builders in Boulder County
- Major remodels and additions with open framing
- Homeowners building an energy-efficient custom home
- Projects targeting green-building or net-zero goals
- Builders needing a reliable, code-savvy insulation sub
What affects the cost
New-Construction Insulation questions, answered
Yes — builders and general contractors are a core part of our work. We act as a reliable, code-savvy insulation subcontractor: designing the whole-home system, installing to spec on schedule, and coordinating blower-door testing and inspections so the project passes the first time.
Boulder and Boulder County enforce advanced energy codes with specific insulation R-values, air-tightness requirements verified by blower-door testing, and sometimes whole-home performance targets. The exact requirements depend on the project. We build to the applicable code and handle the verification steps so your build passes.
Because open framing is the only time you can get every detail right — the best product in each location and a truly continuous air barrier, including spots that are impossible to reach once drywall is up. Insulating during construction produces a higher-performing, more comfortable home than any retrofit can.
Absolutely. A high-performance insulation and air-barrier system is the foundation of any net-zero or green-building project. We design the envelope to your performance targets and coordinate with your energy consultant or rater so the whole-home numbers come together.
