What is Thermal Insulation and Is It Really Beneficial?

insulation and encapsulation installation

The crawl space impacts the energy efficiency of your Minneapolis, MN, home. An uninsulated crawl space allows the transfer of heat from the outdoors and indoors. Usually, this leaves you with uncomfortable indoor temperatures and high energy bills.

When it comes to moisture control and energy efficiency, nothing beats thermal insulation. This solution keeps your home’s temperatures comfortable and consistent all year round, all the while ensuring your energy bills remain unchanged.

What is Thermal Insulation?

Thermal insulation is a method of preventing heat transfer between the exterior and interior of your home. This type of insulation combines special materials that lower or bar thermal conductivity. When done correctly, this technique helps you maintain optimal temperature. You won’t have to heavily rely on your heating or cooling system to regulate internal conditions in your home.

What Makes Thermal Insulation Different from Regular Insulation?

The main difference between thermal insulation and other insulation materials is the R-value, flammability, and how they impact the environment. R-value refers to how well an insulation material resists heat transfer.

Thermal insulation stops heat transfer by reflecting heat back into the crawl space. It’s this property that makes it useful in conserving energy. Some of the most common thermal insulation materials include:

  • Fiberglass
  • Cellulose
  • Polyurethane foam
  • Mineral wool
  • Cellulose
  • Expanded polystyrene

Note that while all these materials prevent heat exchange, some work better than others. Fiberglass, for instance, is the most commonly used thermal insulation material. However, it is easily saturated and can quickly become a breeding ground for mold, mildew, and pests.

We strongly recommend that you use rigid panels made of expanded polystyrene foam insulation because it has a higher R-value. This material is infused with graphite to improve its insular ability. In addition, it’s resistant to mold, pests, and water.

Thermal Insulation Installation — What are the Steps?

Wondering how a contractor isolates the crawl space from the outside? A typical installation in Minneapolis, MN, goes like this:

  1. Contractor measures the area they want to insulate
  2. Contractor seals leaks and gaps using foam insulation
  3. Crawl space walls are insulated using water-resistant rigid foam like ExTremeBloc™
  4. Crawl space is encapsulated with a moisture and vapor barrier
  5. Vent covers conceal open crawl space vents to prevent outside air, water, and pests from coming in

Steps may vary depending on the condition of your crawl space. Most contractors start with conducting an initial inspection to determine how best to install the insulation. If you’re still not convinced as to whether to install thermal insulation, here are a few benefits to expect.

Benefits of Thermal Insulation

Here are several reasons why you should insulate the crawl space of your home:

Reduces Moisture Levels: When your crawl space walls are not insulated, cold vapor from the outside can get in, condense, and cause damage. Thermal insulation acts as an antidote to this phenomenon.

Energy and Cost Saving: A lot of people are conscious about energy consumption. Since thermal insulation blocks exterior temperature from affecting the indoor conditions, no extra energy is required to warm it up. This translates into significant cost savings.

Environmentally Friendly: Climate change is a significant threat to our world today. Thermal insulation reduces energy use especially when heating, thereby reducing your carbon footprint.

Protects Underlying Structure: Thermal insulation together with encapsulation stops beams and joists from the elements and external temperature stress. This reduces the possibility of cracks appearing on your walls and floors.

Positive Effect on Your Health: Thermal insulation is also instrumental in the distribution of indoor air, enhancing comfort level in your home. Insulation measures, coupled with dehumidification efforts, also contribute positively to your health by preventing factors like mold, fungus, dust, and air pollution, which pose health risks.

Don’t take chances with the crawl space as it invariably affects the warmth and dryness of your home. DIY is possible, but it’s not the best way to go. For the best outcome, let professionals handle the installation as they have the expertise and tools to do a satisfactory job.
