New Construction Insulation

New ConstructionInsulation in Minnesota

Trust Works insulates new homes, additions, and garages with spray foam while the framing is still open. We air-seal the whole envelope from the ground up so your build is tight, quiet, and comfortable from day one. Fully insured, with 20+ years of experience.

Build It Right

The envelope is easiest to seal before the walls close.

New construction is the one time you have open framing and full access to the entire building envelope. That is the moment to air-seal and insulate properly, because every gap you close now is a gap you will never have to chase down later. Spray foam takes advantage of that open access to seal the walls, ceilings, and rim joists in a way that batts simply cannot match once drywall goes up.

We work with homeowners, builders, and general contractors on new homes, additions, garages, and finished basements across Minnesota. Insulating at the framing stage means a tighter, quieter, more comfortable home, and a building envelope that performs the way our climate demands from day one.

Open Or Closed Cell

The right foam for each part of the build.

Both open-cell and closed-cell spray foam air-seal as they insulate. The right choice depends on the assembly, the space you have, and whether you need a vapor retarder. On most new builds we use a mix of the two, matched to each area.

Open-Cell Foam

Softer, lighter, expands more

Excellent air seal for interior walls, ceilings, and vaulted or cathedral roofs
Great sound dampening between rooms and floors
Fills deep and irregular framing cavities completely
A cost-effective way to seal large areas where space is not tight

Closed-Cell Foam

Rigid, dense, higher R per inch

The highest R-value per inch, ideal where cavity depth is limited
Acts as a vapor retarder for rim joists, basements, and below-grade walls
Adds rigidity and strength to the assembly
The standard choice for foundation and rim joist areas in our climate

Not sure which belongs where? We spec the right foam for each assembly during the estimate, so nothing is over- or under-built.

Code & Comfort

Meet code and beat it on comfort.

Minnesota's energy code sets the minimum for insulation and air tightness in new homes, and spray foam makes hitting those targets straightforward because it air-seals and insulates in a single step. A tight, well-insulated envelope also lets your heating and cooling system be sized and run more efficiently, which pays off every month you own the home.

Beyond the numbers, an air-sealed new build is simply more comfortable to live in. No cold spots along exterior walls, fewer drafts, less outside noise, and a home that holds its temperature evenly from room to room. {{NEW_CONSTRUCTION_CODE_NOTE}}

How It Works

Our new construction process.

STEP 01

Review Plans

We look at the plans and framing, coordinate with your builder, and spec the right foam and thickness for each part of the envelope.

STEP 02

Schedule the Rough-In

We time our work to the build so insulation goes in after rough mechanicals and before drywall, with no delays to your schedule.

STEP 03

Air-Seal & Insulate

We spray open or closed-cell foam through the walls, ceilings, and rim joists, sealing the envelope as we insulate.

STEP 04

Inspect & Hand Off

We verify coverage and thickness, clean up the site, and leave the framing ready for the next trade.

Common Questions

Frequently asked questions.

New construction is the ideal time to spray foam because the framing is open and fully accessible. Foam air-seals and insulates in one step, filling every gap and stopping the air leakage that fiberglass batts leave behind. The result is a tighter, quieter, more comfortable home with a building envelope that performs better through Minnesota winters and summers.
