Whether you’re living in the hot deserts of Arizona or on the snowy Michigan coast, proper insulation is the key to maintaining a comfortable home. In extreme conditions, whether hot, cold, or humid, the right insulation type and expert installation make all the difference in preventing air leakage and moisture buildup.

When considering the best option for extreme weather, batt insulation stands out as one of the most cost-effective options. In this blog, we’ll cover everything you need to know about batts, from different material types to the benefits in extreme climates, so you can save on heating and cooling costs in any weather.

Understanding Batt Insulation

One of the most common insulation types, batts are pre-cut insulation sheets that can easily be cut and fitted into attics, basements, walls, and more. This makes them far less messy when compared to spray foam insulation. Standard batts measure 48 inches or 96 inches long, with a thickness of 3.5 inches.

What is Thermal Performance?

Thermal performance is how well an insulation material can resist heat transfer. This performance is typically measured as the R-value, and determines how well it can maintain a stable temperature in the building. In summer, this means resisting heat flow to keep it cooler, while in winter, high quality insulation keeps warm air inside.

We always recommend choosing a material that offers an R-value aligned with your region’s climate and your specific needs. Here are some general guidelines:

  • Summer: 1–2 R-value
  • Shoulder seasons: 3–5 R-values
  • Winter: 6+ R-values
Types of Batt Insulation

Batt insulation comes in a variety of materials, helping you save even more on air conditioning or heating costs, depending on the material you choose. Different materials offer unique R-values, climate advantages, and other factors that impact thermal performance.

  • Fiberglass Batts Insulation: The most common insulation material, fiberglass insulation typically has an R-value between R-2.9 to R-3.8 per inch. It’s lightweight and easy to install but requires proper safety gear during installation to prevent skin irritation.
  • Mineral Wool Batts Insulation: The most expensive option, mineral wool is a heavier material and offers the highest R-value (between R-3.0 to R-4.3 per inch). This, combined with exceptional moisture resistance, makes it the best batter option for cold climates or areas that require fire resistance (up to 1,800°F).
  • Cellulose Batts Insulation: Made from recycled materials and flexible, cellulose insulation offers an R-value between R-3.2 to R-3.8 per inch. It can fit easily in irregular spaces but do keep in mind that it can absorb moisture, so proper vapor barriers may be needed to prevent mold growth

Batt Insulation For Hot Climates
In the hot deserts of the Southwest or during the warm summers of the Southeast, insulation needs to effectively block heat transfer while providing proper ventilation. Both fiberglass and cellulose batts are good choices, the former being preferable for wetter heat and the latter for dry heat. However, we generally recommend fiberglass, as it’s affordable, offers high thermal resistance, and an effective moisture barrier.
Reduces Heat Gain
Both fiberglass and cellulose batts slow down heat transfer, maintaining cool air throughout your home without putting pressure on air conditioning systems. By preventing cool indoor air from getting out and hot outdoor air from seeping in, you can reduce energy bills throughout the summer.

Lightweight and Breathable

Unlike denser mineral wool and other insulation materials, fiberglass and cellulose are lightweight and breathable, allowing for better airflow. This further aids in maintaining a balanced indoor temperature that doesn’t trap excess heat.

Moisture Resistance

If your region’s hot summers also bring rain and humidity, fiberglass is typically the best option. Unlike cellulose, it’s highly effective in resisting moisture absorption, reducing the risk of mildew and mold growth. Installing a proper vapor barrier can also enhance insulation performance in the summer.

Batt Insulation For Humid Climates

Whether you’re dealing with the hot, wet bayou or Cascadia’s winter rains, humid regions require moisture resistance and thermal performance. Fiberglass and mineral wool batts are the best choice, with the latter providing the best natural moisture resistance even when exposed to damp conditions.
Prevents Mold and Mildew
Mineral wool and fiberglass don’t absorb moisture, making it easier to prevent mold and mildew buildup. In regions where high humidity is common, these properties are crucial for preventing slow and steady water damage over time.
Maintains Insulation Performance
Some insulation materials lose effectiveness when damp, but mineral wool and fiberglass batts retain their insulating properties even in the most humid conditions. This allows for an energy efficient home that saves you money on heating and cooling costs.
Improves Indoor Air Quality
While more expensive, mineral wool batts is the best option for maintaining indoor air quality. Compared to fiberglass or cellulose, it resists mold more effectively and prevents the release of airborne fibers, creating healthier indoor air.
Batt Insulation for Cold Climates
For the freezing winters of Maine and Minnesota, thermal insulation materials with high performance are essential. Mineral wool batts offers excellent thermal resistance (R-3.0 to R-4.3 per inch), strong air-sealing properties, and fire-resistant qualities, making it the best choice for frigid weather. Their dense structure also helps trap heat inside, preventing energy loss and keeping homes warm.

Enhances Heat Retention

With the highest r-value of any batt insulation option, mineral wool insulation retains indoor warmth more effectively. The result: reduced heating costs in cold temperatures.
Fire Resistance for Added Safety
Homes in cold climates typically have fireplaces or HVAC heating systems that can pose a fire safety risk in your home, but mineral wool’s natural fire resistance can create a safer environment. Mineral wool withstands temperatures up to 1,800°F.
Reduces Drafts and Air Leaks
Due to its dense composition, mineral wool effectively seals even the smallest gaps and crevices around your home. This prevents cold drafts from entering and ensures a more comfortable indoor environment.
