Frequently asked questions
How much blown-in insulation do I need in my attic?
Minnesota homes typically benefit from R-49 to R-60 in the attic, depending on the home. We'll measure existing depth, recommend a target R-value, and quote the project around that.
Is blown-in fiberglass better than blown-in cellulose?
Both work. Blown-in fiberglass is non-combustible, doesn't absorb water the same way, and resists settling. We focus on blown-in fiberglass because it performs consistently in Minnesota attics over the long haul.
Can I add blown-in insulation over existing insulation?
In most cases, yes. We inspect what's already there, address any air-sealing issues first, then blow new insulation over the top to reach your target R-value.
Do you offer blown-in insulation near me?
Yes — we serve Princeton, Cambridge, Zimmerman, Milaca, Elk River, and surrounding Central Minnesota communities.
