The Great Lakes Chill Factor: How Michigan’s Humidity & Lake Effect Snow Impact Insulation Needs

June 30, 2024by Whitson

As Michigan-based insulation experts, we’ve seen firsthand how our unique climate can wreak havoc on local homes. If you’re a Michigan homeowner, this guide will reveal how the right insulation can protect your home, slash energy bills, and keep you cozy all year round. Let’s dive into the challenges posed by our Great Lakes region and how to conquer them.

Michigan’s Microclimate: More Than Just Snow

The Great Lakes do more than provide stunning views–they significantly impact our weather. While these vast bodies of water moderate air temperatures, they also contribute to high humidity levels, especially in summer. That is, in part, thanks to the significant amount of water vapor the Great Lakes release into the air through evaporation, adding moisture directly to the atmosphere. But it’s the infamous lake effect snow that creates unique challenges for insulation.

Lake Michigan and the other Great Lakes can cause rapid temperature swings, leading to condensation and moisture buildup in your home. This means standard insulation recommendations for other parts of the United States often fall short for Michigan homes. We need to think bigger and smarter.

Michigan Humidity

Summer in Michigan isn’t just about beaches and barbecues. High humidity can lead to a host of problems:

  • Mold growth in attics, walls, and crawl spaces
  • Wood rot and structural damage
  • Increased cooling costs as your AC works overtime
  • Uncomfortable indoor air quality

To combat this, proper ventilation and vapor barriers are crucial companions to insulation in managing moisture. Without them, even the best insulation can become compromised.

Lake Effect Snow: When Insulation Becomes Your Shield

Come fall and winter, lake effect snow dumps massive amounts of snowfall on parts of Michigan. This winter weather phenomenon occurs when cold air moves across the warm waters of the Great Lakes, picking up moisture and depositing it as snow on the leeward shores. The results can be dramatic:

  • Ice dams on roofs, causing leaks and damage
  • Increased heat loss through poorly insulated attics
  • Frozen pipes and potential plumbing disasters

Sufficient attic insulation and proper roof ventilation are your best defenses against these winter woes. They help maintain consistent surface temperatures on your roof, preventing the freeze-thaw cycle that leads to ice dams.

Choosing the Right Insulation for Michigan’s Unique Challenges

Closed Cell Spray Foam: Spray foam insulation offers excellent moisture resistance, high R-value, and insulates and air seals in one step. It is applied as a liquid and expands to fill a space and fill air leaks. Spray foam comes in both open cell and closed cell form.

Cellulose: Dense-packed cellulose insulation is made from recycled paper products and is great for filling gaps and closed spaces and helping with air sealing.

Fiberglass Batts: Fiberglass insulation is manufactured from recycled glass and is the most affordable and widely used option, but batt insulation can be less effective against moisture without a vapor barrier.

Now that you know about the various types, you can focus on properly insulating these key areas of your home:

Attic Insulation: Attic insulation is crucial for minimizing ice dams and reducing heat loss.

Basement and Crawl Space Insulation: Insulating and air sealing your basement and crawl space will protect your home against moisture and cold floors.

Wall Insulation: Wall insulation creates a thermal barrier for year-round comfort and aids in sound proofing too.

Beyond Insulation: Additional Tips for Michigan Homes

The National Weather Service often warns of extreme cold and large-scale snow accumulation in our region during the winter season. By taking these steps, along with insulation, you’ll be well-prepared for whatever Mother Nature throws your way:

Proper Ventilation

Ensure your home has adequate attic and crawl space ventilation to control moisture.

Air Sealing

Seal all the gaps and cracks in your home to prevent drafts and reduce energy loss.

Regular Inspections

Frequently check for signs of moisture damage or inadequate insulation.
