Spray Foam Insulation in Royalton, MN
Open- and closed-cell spray foam insulation for homes, cabins and outbuildings.
Open-Cell and Closed-Cell, Matched to the Building
Spray foam is two different products. Closed-cell foam is dense, moisture-resistant and strong - the premium choice for steel buildings, rim joists, rooflines and anywhere moisture control matters, and it is our specialty. Open-cell foam is lighter and more economical per inch, a good fit for filling large framed cavities and quieting sound where the assembly stays dry.
Which one? Depends on the assembly. A lakes-area cabin roofline, a Royalton farmhouse rim joist and a St Cloud warehouse wall each want a different spec. On the estimate we walk the building with you, explain the trade-offs in plain language, and write down what we would spray and how thick.
Foam does two jobs at once. It insulates, and it closes the small air leaks that let January into the house. Fiberglass only does the first one.

Common Questions
Open-cell or closed-cell: which do I need?
Closed-cell where moisture or strength matters, which means steel buildings, rim joists, basements and most Minnesota rooflines. Open-cell where you are filling large framed cavities in a dry assembly and want more inches per dollar. We spec it per assembly on the estimate.
Does spray foam need a vapor barrier in Minnesota?
It depends on the assembly and the installed thickness. Closed-cell at adequate thickness acts as its own vapor retarder; open-cell generally does not. We confirm what your specific wall or roof needs rather than applying one rule everywhere.
How soon can we re-enter the house after spraying?
There is an odour during and shortly after application that clears as the foam cures. Re-entry time varies by product and ventilation, so we give you the manufacturer's figure for the exact product before the crew arrives.
