Basement Insulation in St. Paul, MN and surrounding areas: Comfort Starts from the Ground Up

Whether it’s freezing cold in the winter or hot and humid in the summer, basements in Minnesota are a major source of energy loss and indoor discomfort. At Koala Insulation of St Paul, we specialize in high-performance insulation solutions that help you take control of your home’s temperature, air quality, and energy bills—year-round.

Our top recommendations? Closed cell spray foam insulation and crawlspace encapsulation—two proven solutions that effectively block both heat and cold, moisture, and pests.


Why Basement Insulation Matters in Every Season

Your basement plays a critical role in your home’s overall comfort and energy efficiency. Without proper insulation, the space becomes a conduit for:

  • Cold drafts and freezing floors in winter
  • Overheating and moisture buildup in summer
  • Unwanted humidity and musty odors
  • Pest infestations and rodent access points
  • Increased heating and cooling costs

No matter the season, insulating your basement properly means your HVAC system won’t have to work as hard—and your living space will feel noticeably more comfortable upstairs and down.


Targeted Solutions for Year-Round Protection

At Koala Insulation of St Paul, we don’t believe in one-size-fits-all insulation. We provide strategic, climate-appropriate solutions designed to perform in Minnesota’s extreme weather conditions.


Closed Cell Spray Foam for Rim Joists & Basement Walls

Closed cell spray foam is our go-to solution for sealing out both cold and heat. It forms an airtight, moisture-resistant barrier along basement rim joists and walls, keeping conditioned air in and outside temperatures out.

Benefits include:

  • High R-value for superior thermal resistance
  • Year-round comfort—warm in winter, cool in summer
  • Excellent moisture control to prevent mold
  • Effective rodent and pest deterrent
  • Long-lasting and energy efficient

Crawlspace Encapsulation

If your home has a crawlspace, it could be contributing to hot, humid air in summer and icy cold floors in winter. Our crawlspace encapsulation service seals off the space using vapor barriers and spray foam to control temperature, moisture, and air quality from the ground up.

Crawlspace encapsulation helps with:

  • Reducing cold or hot air rising through floors
  • Preventing musty smells and mold
  • Improving indoor air quality
  • Keeping rodents and pests out
  • Boosting year-round energy efficiency
