Use Closed Cell Spray Foam Insulation to Seal & Insulate a Sauna or a Steamroom

seal and insulate your sauna

Saunas and Steamrooms are designed to hold high levels of heat in a small space, no matter what the temperature is outside.

Unlike a hottub where the pumps will keep running, many believe an outdoor sauna doesn’t need insulation because it’s only being heated when in use.

But, with proper insulation, you don’t need to use as much energy and time to heat the sauna before and during use.

Think of it this way, it takes a lot less time to bake your pizza if you close the oven door.

The best way to insulate a space like this is with closed cell spray foam insulation.

It has a very high r-value per inch.

It seals airflow.

And, with Foam it Green, it also is ASTM G21 certified mold resistant, which is extra important if you’re doing a steamroom.
