CH 01 · The climate

Five months
of winter

Southeast Idaho runs twenty below. Every building out here is in a fight it didn't pick.

CH 02 · The leak

40%

of heat loss is air leakage

Escaping through gaps and seams fiberglass can't close. You're paying to heat the outdoors.

CH 03 · The material

R-7.4

per inch

2lb closed-cell foam — the highest R-value you can put in a wall. Nearly double fiberglass.

CH 04 · The bonus

Condensation dies at 1 inch

Closed-cell is its own Class II vapor retarder — no more ceilings raining inside your metal building. And it bonds structural, stiffening the whole assembly.

CH 05 · The fix

One owner.
One pass. Airtight.

Drop in.

Stop paying to heat the outdoors.

Owner-operated closed-cell foam insulation for Southeast Idaho & Cache Valley. The person who quotes your job is the person who sprays it.

// Why closed-cell

Fiberglass fills a wall.
Closed-cell seals a building.

You met the numbers on the way down the mountain. Here's the full case.

R-7.4
per inch, every depth

Highest R-value available

7.4 per inch — nearly double fiberglass — and it holds at every thickness. Critical when Idaho winters hit -20°F and every inch of cavity counts.

~40%
of heat loss is air leakage

Complete air seal

Air-impermeable foam that expands into every gap, crack, and penetration. Fiberglass doesn't stop moving air — this does.

1"
= Class II vapor retarder

Moisture control built in

At just one inch it's a Class II vapor retarder — 0.86 perm. No condensation dripping off your metal building's ceiling.

>97%
closed-cell content

Structural rigidity

Over 97% closed cells — rigid, water-resistant (under 1% absorption), and bonded to your framing. The only insulation that makes the building stronger.

// How a job goes

One pass.
Sealed for good.

Prepped, sprayed, and cured in a single visit. Here's the sequence.

  1. Prep & maskWindows, outlets, and finished surfaces protected before the gun ever fires.
  2. Spray liftsFoam applied in controlled lifts for full adhesion and in-spec density.
  3. 30x expansionLiquid becomes rigid foam in seconds, driving into every gap and seam.
  4. Sealed envelopeAir barrier, vapor retarder, and full R-value — cured and done in one visit.
// What we spray

Built for the buildings people actually own out here

01 · Shops & pole barns

Metal buildings

Kill the condensation, keep the shop warm enough to work in January. The single best upgrade a metal building can get.

02 · New construction

Walls & rim joists

Seal the envelope right the first time. Rim joists are the leakiest part of any new house — foam ends that.

03 · Under the house

Crawl spaces

Cold floors and frozen pipes start in the crawl space. Encapsulate it and the whole house changes.

04 · Overhead

Cathedral ceilings & attics

Unvented roof assemblies done correctly — full R-value in tight rafter bays where batts physically can't perform.

05 · Ag & commercial

Barns, cellars, outbuildings

Potato cellars, equipment storage, livestock buildings — anywhere temperature swing costs you money.

06 · Not sure?

Call and describe it

If foam is the wrong answer for your building, I'll tell you that too. I'm after the right fix and a result that holds up — not just another sale.

// Owner-operated. On purpose.

The guy who quotes your job is the guy who sprays it.

Summit Spray Foam is one owner, one rig, zero crews. That's not a limitation — it's the whole point.

I've run crews before, so I know where quality gets risked on a bigger operation: in the handoff — between the person who sells the job and the person who actually sprays it. Summit is built to remove that handoff completely.

When I walk your job, the number I give you is the number. When the rig shows up, I'm in it. No new-guy learning on your walls. Every board foot gets sprayed by the person whose name is on the truck.

The standing promise
  • You deal with the owner from first call to final walkthrough
  • Written quote with thickness, coverage, and R-value spelled out — no vague bids
  • 2lb closed-cell foam, in-spec and in-date, every job
  • Job site left cleaner than a lot of contractors' shops
  • If foam isn't right for your building, I'll say so and walk away

// Cool facts

Foam is wilder than you think

A few things about closed-cell spray foam that surprise most people.

30x

It grows in seconds

Sprayed on as a liquid, closed-cell foam expands roughly thirty times its volume in seconds — driving into gaps you can't even see before it turns rigid.

NASA

Rocket-grade insulation

The Space Shuttle's giant orange fuel tank was insulated with sprayed-on polyurethane foam — the same chemistry family that seals your walls.

3-in-1

One product, three jobs

Closed-cell is insulation, air barrier, and vapor retarder all at once — doing the work of three separate materials in a single pass.

GWP 1

Cleaner than it used to be

The modern HFO foam we spray has the same global-warming potential as plain CO₂ — roughly a thousand times lower than the blowing agents used a decade ago.

It floats

Built to shrug off water

The same two-part polyurethane foam family is used for flotation in boats — rigid, buoyant, and soaking up less than 1% of its volume in water.

Lifetime

It doesn't quit

Once cured, closed-cell foam won't sag, settle, or lose R-value — it holds its seal for the life of the building while fiberglass compresses and droops.
