St. Croix Energy Solutions offers attic insulation to make sure your Twin Cities-area home stays comfortable year-round. Not all insulation is created equal, and we insist on the best.

Cellulose is King

In the case of attic insulation, tried and true cellulose insulation is by far the superior choice. Cellulose offers a multitude of benefits for application in attics, including:


Cellulose is denser than fiberglass or mineral wool, containing many more, much smaller fibers and smaller air spaces that better trap heat to keep it where it is. Fiberglass, on the other hand, begins to lose R-Value as cold attic air cycles down into its fewer, bigger air pockets.

Retrofitting in Hard-to-Reach Spots

Blown in cellulose is an excellent material for retrofitting in existing homes. It creates a monolithic layer across the attic, filling in the nooks and crannies left by existing insulation.  This type of cellulose can easily be blown into the tight spaces and far reaches of the attic.

Better with Time

Over the years, cellulose forms an almost paper mache-like crust on its surface, which bolsters its air barrier properties, allowing it to better keep heat and cool where it belongs.

Prevent Fires AND Bugs

Cellulose is famously pest- and fire-resistant thanks to Borate treatment, a mineral additive that never loses its effectiveness (and is safe enough to be one of the main ingredients in eye-drops!).


Cellulose is made with over 80% post-consumer recycled content, making it one of the “greenest” insulation options available. It also has the lowest embodied energy (the total energy required to produce a material) and the smallest carbon footprint of any other insulation product.

After testing thousands of homes, our results back up what the national certifying laboratories claim: attics insulated with cellulose maintain high R-Values under all conditions, are better air sealed, and harbor fewer pests.

St . Croix County Historical Society is gratefully pleased with the service and advise provided by St Croix Energy Solutions . SCES performed a thorough energy audit of the Octagon House Museum and the caretaker's apartment free of charge. Their representative, Pete Morsch, willingly attended a meeting of the Board of Directors to explain his recommendations for the Museum complex. Pete made several visits to the Museum to fully examine the premises. The Society Board of Directors agreed to the installations recommended to the extent our budget would allow. SCES also advised SCCHS regarding available rebates toward the cost of the energy upgrades that were made.
