Insulation Types
The Right Material for Every Park City Assembly
We specify across every insulation method for Summit County's Climate Zone 6 conditions — not just the one our crew happens to carry. The recommendation follows the building.
Open & Closed Cell
Spray Foam
Specified by assembly and moisture risk — the right call for Park City's freeze-thaw cycles and high-altitude moisture loads.
Closed-cell where the assembly demands it, open-cell where it doesn't. Spray foam expands on contact to seal air gaps, create a vapor barrier, and add structural rigidity — critical in Park City's Climate Zone 6 where air sealing is as important as R-value. We don't upsell spray foam into applications where blown-in or batt delivers the same outcome at a fraction of the cost.
Cellulose & Fiberglass
Blown-In
The fastest way to bring a Park City attic up to Climate Zone 6 R-49 without tearing anything apart.
Blown-in loose-fill fills every corner of an irregular attic cavity under pressure — no gaps, no voids. Cellulose is our default for Park City retrofits: it's dense-pack capable, fire-resistant, and made from recycled content. Most Park City attics are completed in a single day, with minimal disruption to vacation rental schedules.
Fiberglass & Mineral Wool
Batt & Roll
Code-compliant, cost-effective, and the right call for open-stud new construction throughout Summit County.
Fiberglass and mineral wool batts are the workhorses of new construction — cost-effective between studs and joists, and mineral wool's fire resistance is a meaningful advantage in Utah's wildfire-adjacent terrain. Park City's WUI (Wildland-Urban Interface) zones make mineral wool's non-combustibility a real specification consideration, not just a nice-to-have.
Continuous Insulation
Rigid Board
The answer to thermal bridging that batt insulation can't solve — especially important in Park City's high-performance new builds.
Rigid foam board installed continuously over studs eliminates the thermal bridging that undermines cavity insulation. It's the right call for high-performance wall assemblies, basement walls, and under-slab applications in Park City's mountain climate where continuous thermal breaks make a measurable difference in heating loads.
Fire & Acoustic Performance
Mineral Wool
Where fire resistance or sound control is the primary design requirement — common in Park City's multi-unit and resort properties.
Mineral wool (rock wool / slag wool) is non-combustible, dimensionally stable, and an excellent acoustic absorber. It's the specified choice for party walls, mechanical rooms, WUI-zone construction throughout Summit County, and any assembly where fire resistance is a code or insurance requirement. Particularly relevant for Park City's high-density resort-area developments.
Applications
Applications Covered in Park City & Summit County
Residential, commercial and specialty work throughout Park City, Deer Valley, Kimball Junction, Jeremy Ranch, Snyderville Basin, Heber City, Midway, and surrounding communities.
Residential Retrofit
Attics, walls, crawl spaces, rim joists and basements in existing Park City homes — from 1970s ski cabins to contemporary Deer Valley estates.
New Construction
Full-envelope specification and install for Summit County builders, coordinated around framing and drywall schedules. Climate Zone 6 compliant.
Vacation Rentals & Second Homes
Retrofit insulation for Park City's large vacation rental inventory — scheduled around rental calendars to minimize downtime and lost revenue.
Commercial & Light Industrial
Warehouses, shops, multi-unit and mixed-use buildings throughout Summit County, including firestopping and joint penetration work.
Radiant Floor & Snowmelt Systems
Load-rated under-slab insulation so purchased heat moves where it's supposed to — up into the room or out to the surface, not down into the ground. Common in Park City's heated driveways and ski-in/ski-out properties.
Swimming Pools & Spas
Pool shell, equipment room and heated-deck insulation — where uncontrolled heat loss quietly runs up the largest utility bill on the property. Particularly relevant for Park City's year-round outdoor pool and hot tub installations.
