Spray Foam Insulation Built for Flint Hills Weather
Kansas weather is notorious for extreme conditions. Now is the time to insulate your home to combat the freezing winters or scorching summers. 785 Insulation seals homes, ag buildings, and commercial spaces across the Manhattan, KS region so you stop heating and cooling the outdoors. Free, no-pressure estimates.
Why Homeowners Across the Flint Hills Choose Spray Foam
Batt and blown-in insulation slow heat transfer. Spray foam does that and seals the gaps, cracks, and penetrations that let outside air in around them — which is where most Kansas homes actually lose energy.
Lower Energy Bills
Closes air leaks other insulation types can't reach, so your furnace and AC run less to hold the same temperature.
Moisture & Mold Control
Kansas humidity swings hard between seasons. A tight envelope keeps moist air from condensing inside your walls.
Built to Last
Unlike batts and blown-in fiber, spray foam won't sag, settle, or lose R-value over the life of the building.
Stronger, Quieter Home
Closed-cell foam adds real structural rigidity to walls and roof decks, and cuts down outside road, wind, and livestock noise.
Spray Foam Insulation for Every Kind of Flint Hills Building
From a Manhattan starter home to a pole barn outside Wamego, we scope every job to the building — not a one-size-fits-all bid.

No stock photos here — these are actual 785 Insulation jobs across the Flint Hills, showing exactly what proper coverage looks like.
Full Roof Deck Coverage
Closed-cell foam sprayed directly to the underside of the roof deck seals out condensation and radiant heat — the difference between a shop that sweats in July and one that doesn't.
Every Stud Bay, Fully Filled
No gaps, no compression, no missed corners. Closed-cell spray foam expands to fill the entire cavity and bonds to the framing, so there's no path left for air to sneak through.
Wall-to-Ceiling on Larger Buildings
On bigger interior spaces, we treat walls and ceiling as one continuous envelope — consistent R-value from floor to roofline, with no cold spots along the way.
We're Not a National Chain. We're Your Neighbors.
The Flint Hills aren't like anywhere else — thin, rocky soil that never got plowed under, tallgrass prairie running to the horizon, and sunsets that stop traffic on K-18. We grew up under those same skies, and we built 785 Insulation to serve the homes, farms, and businesses in this exact stretch of Kansas.
That means we know what a Manhattan attic does in August, what a Fort Riley-area crawl space does in January, and why a pole barn outside Council Grove sweats when the temperature swings 40 degrees in a day. We size every job around this climate, not a national average.
