Metal Building Insulation

Metal BuildingInsulation in Minnesota

Trust Works insulates steel-frame and metal-panel buildings across Minnesota with spray foam. We stop condensation on the steel, air-seal the envelope, and make metal shops and commercial buildings comfortable and efficient. Fully insured, with 20+ years of experience.

The Problem

Steel is efficient to build and hard to insulate.

Steel-frame and metal-panel buildings go up fast and hold up for decades, but the same steel that makes them durable makes them a challenge to keep comfortable. Metal conducts heat and cold straight through the envelope, and warm interior air condenses on the cold steel panels and framing, dripping onto whatever is stored or worked on below.

The traditional fix, fiberglass rolls draped behind the panels, sags, compresses, and traps moisture over time, and it never truly stops the air leakage or the condensation. Spray foam is the direct answer: it bonds to the steel, air-seals the envelope, and controls the moisture that causes the dripping, all in a single application.

Why Foam

Closed-cell foam sticks to steel and stops condensation.

Sprayed to the interior side of the panels and into the framing, closed-cell spray foam adheres to the steel and cures into a rigid, air-tight, moisture-resistant layer. By keeping warm, humid interior air off the cold steel, it stops condensation at its source, and its high R-value per inch delivers real insulation in the shallow depth a metal building gives you.

It does not sag, settle, or wick water the way batts and rolls do in a steel building, so it keeps performing for the life of the structure. Where the assembly allows and condensation is not the concern, open-cell foam can be used to seal larger areas at a lower cost. We spec the right foam for each part of the building during the estimate.

Bonds directly to steel panels and framing and stays put
Stops condensation by sealing warm air off the cold metal
High R-value per inch for the shallow depth of a metal wall
Cuts air leakage so heating and cooling systems work less
What We Insulate

Steel structures of every kind.

From small steel shops to large commercial steel-frame buildings, spray foam seals and insulates the envelope. Common projects include:

Steel Shops & Garages

Comfortable, heatable work space

Dry, heatable interiors you can work in year-round
Even temperatures with no cold spots at the panels
Reduced noise inside the building

Commercial Steel Buildings

Retail, office, and mixed use

Lower heating and cooling load across the envelope
A tighter building that holds its temperature
A more comfortable space for staff and customers

Equipment & Storage

Protect assets from moisture

Stops condensation that rusts equipment and inventory
Holds temperature for sensitive storage
Seals out drafts, pests, and weather

Manufacturing & Shop Floors

Process and production spaces

A stable interior environment for operations
Insulated walls and roof for efficiency
Foam matched to each area of the building
How It Works

Our metal building process.

STEP 01

Walk the Building

We assess the steel, the framing, and how you use the space, then spec the right foam and thickness for the walls and roof.

STEP 02

Prep & Protect

We mask off openings, equipment, and finished areas and prepare the steel for a clean, durable bond.

STEP 03

Spray the Envelope

We apply foam to the panels and framing to the specified thickness, air-sealing and stopping condensation as we insulate.

STEP 04

Inspect & Clean Up

We verify coverage, confirm the condensation problem is sealed, and leave the building clean.

Common Questions

Frequently asked questions.

Warm, humid air inside the building contacts the cold steel panels and framing, where it condenses and drips. Steel conducts cold readily, so the panels stay cold enough to sweat all winter. Closed-cell spray foam stops this by sealing the warm interior air off the cold steel, keeping the panels dry.

Stop the sweat on your steel.
