Why Builders Are Choosing Spray Foam for Steel Buildings and Sheds

Steel buildings and backyard sheds are no longer just for storage. These days, they’re being transformed into workshops, cabins, gyms, barns, and even full-on living spaces—and builders across Nova Scotia are getting creative with how they’re used.

But here’s the thing: insulating these structures properly can be a challenge. Traditional materials like fiberglass or rigid foam just don’t cut it when it comes to metal walls, curved panels, and our damp maritime climate.

That’s exactly why more and more builders are choosing closed-cell spray foam—and if you’ve ever worked on a shed, steel building, or barn, you’re going to want to know why.

The Problem with Traditional Insulation in Metal Buildings

Let’s be real: metal buildings are tough to insulate. They’re drafty, they sweat, and they’re full of weird shapes and tight corners. Batt insulation doesn’t stick, rigid board leaves gaps, and don’t even get us started on vapour barrier struggles.

Common issues with traditional insulation:

• Condensation buildup (a major problem in steel structures)

• Sagging or settling over time

• Mold and mildew from trapped moisture

• Cold floors, hot ceilings, uneven temps

• Difficult installation on curved or ribbed panels

  
  

If you're a builder or contractor, you’ve probably dealt with all of the above. It's frustrating—and it leads to callbacks, complaints, or extra work down the line.

Why Spray Foam Works So Well in Steel Buildings

Here’s where closed-cell spray foam takes the win. It’s not just an insulation product—it’s a sealer, vapour barrier, and moisture-blocking powerhouse all in one.

Why builders love it for steel buildings, sheds, and barns:

• Forms an instant air and moisture seal—no gaps, no drafts

• Stops condensation from forming on metal surfaces

• Adheres directly to steel, wood, or concrete—no fasteners or cutting

• Adds structural strength (yup, really!)

• High R-value per inch = better energy performance

• Won’t sag, fall out, or attract pests

  
  

In other words, it’s fast, durable, and gets the job done right the first time.

Use Cases – Sheds, Barns, Shops & More

You might be surprised at just how many places we’re applying spray foam these days. It's not just big barns or commercial buildings—we're seeing it everywhere:

• Backyard sheds being turned into home offices or cabins

• Garages and workshops used year-round

• Agricultural barns and outbuildings that need moisture protection

• Shipping containers converted into tiny homes or rentals

• Steel-framed buildings for businesses, storage, or retail

If it has walls (or even if it doesn’t yet), there’s a good chance spray foam can be applied and deliver serious results.

Speed + Simplicity for Builders and Contractors

One of the biggest reasons builders keep coming back to spray foam? It saves time and keeps projects on track.

There’s no stapling, layering, or complicated installs—just a smooth, fast spray that covers and seals in one step.

Benefits for your build timeline:

• Installs quickly (especially compared to batts or rigid board)

• No need for vapour barriers or plastic sheets

• Less waste and cleanup

• Perfect for tight deadlines or unpredictable weather

  
  

It’s a one-crew, one-step solution—and it works.

Rebate-Eligible and Energy Efficient

Here’s a bonus: depending on the purpose of the shed or building, Efficiency Nova Scotia rebates may be available—especially if it’s being converted into a conditioned space like a home office, rental, or suite.

Pair that with the energy savings spray foam brings long-term, and you’ve got real value your clients will thank you for.
