Spray Foam Insulation
Open-cell and closed-cell spray foam that seals the gaps, stops drafts and lowers your heating bill. Made for Minnesota winters.
What it is
One application. Insulation and air seal.
Spray polyurethane foam is applied as a liquid that expands in place, filling every crack, seam and cavity. It insulates and air seals at the same time, which batts and loose fill can't do on their own.
We install both open-cell and closed-cell foam and specify the right one for each area of your project. Open-cell is ideal for interior walls, attics and sound control. Closed-cell delivers the highest R-value per inch, adds racking strength and acts as a vapor retarder. We use it a lot on pole buildings, rim joists, basements and crawl spaces.
Open cell vs closed cell
Two foams. One right answer.
Every project is different. We pick the foam that fits each area, and a lot of buildings end up with both.
| Property | Open cell | Closed cell |
|---|---|---|
| R-value per inch | ~R-3.7 | ~R-6.5 |
| Density | Light, soft, flexible | Dense, rigid |
| Air seal | Yes | Yes |
| Vapor retarder | No | Yes (at 2"+) |
| Adds structural strength | No | Yes |
| Sound dampening | Excellent | Good |
| Best for | Attics, interior & exterior walls, sound control | Pole buildings, rim joists, basements, crawl spaces, metal buildings |
Benefits
Why it's worth it.
Up to 50% energy savings
Stopping air leakage is the single biggest lever on heating and cooling costs.
Complete air seal
Eliminates drafts, cold spots and ice-dam-causing heat loss in one pass.
Moisture control
Closed-cell foam resists water and blocks vapor, protecting your structure.
Stronger walls
Closed-cell foam bonds to framing and can add meaningful racking strength.
Quieter rooms
Open-cell foam dampens airborne sound between rooms and floors.
Lasts the life of the building
Foam won't sag, settle or compress over time.
Where it's used
Built for every space.
