Best Residential Insulation for Cold Climates

Here in Minnesota, our climate is undeniably cold. When the summer is over and winter sets in, it gets downright frigid. High-quality insulation is therefore needed to keep homes comfortable not only in the summer but during the winter as well. The right insulation can keep a home safe and heating bills down. But, what types of insulation are best for this cold climate? As the trusted name in insulation including cellulose insulation for St Michael and the surrounding areas, we’ve put together a list of the top choices in insulation for our climate no matter the time of year.

Home Insulation Twin Cities

Before we go into what types of insulation are best for northern climates, we must first talk a bit about the R-Value. It is a metric that stands for the insulation material’s resistance to heat flow. The type of insulation and its R-Value that is needed depends mostly on where you live. In our case of Minnesota, the higher, the better. The general rule is that the higher the R-Value, the better the insulation material.

Blown-In Cellulose Insulation

Blown-In cellulose insulation that has an R-Value of 49 is the best for cold climates. It is effective at all temperatures but can perform even better during cold periods. It’s the best to use in ceilings, open new wall cavities, unfinished attic floors, or other such hard-to-reach places.

Spray Foam Insulation

Spray foam insulation also has a higher R-Value. It can even help eliminate some other tasks, such as caulking since it also forms an air barrier when it settles. It starts as a liquid, and it expands to fill all the available space, thus sealing cracks, gaps, and air leaks. 


For cold climates, loose-fill fiberglass insulation has a great R-Value too. It will also not lose its energy-saving capabilities over time. It is non-combustible, non-corrosive & non-absorbent. If exposed to moisture, fiberglass will not hold water. We install high-quality JM fiberglass insulation. When you have us upgrade your insulation needs with JM fiberglass insulation, you can expect year-round comfort.

All three of these solutions work best for our cold climate in Minnesota and here at Lewis Insulation, we supply all three! Not sure which one to choose? Allow our experts to help you select what will work best for your home.
