Does Insulation Add Value to My Home?


Adding insulation will always enhance the value of your residential property. Insulation improves the comfort and health of your living space and provides a range of other benefits. Some benefits include but are not limited to:

  • Increased energy efficiency
  • Boosted durability of your property
  • Added appeal to any potential buyers

Increasing the value of your property is an important aspect of property ownership. Check out some more benefits here.


The Effectiveness of Spray Foam and Fiberglass in Your Home


Both spray foam insulation and fiberglass insulation can last from 80-100 years in your home. However, if fiberglass meets moisture, the fibers can lose their effectiveness. Also, fiberglass allows air to pass through it, whereas spray foam does not as it air seals. While North Carolina’s climate is mostly moderate, we are used to seeing a few muggy months with high humidity and elevated temperatures.

Spray foam insulation is worth the higher cost to combat these high humidity periods. Despite its slightly higher cost, the investment in spray foam insulation will pay off significantly during those periods of elevated humidity. Spray foam insulation is a worthwhile choice for those seeking unparalleled comfort and protection for their homes. This is because spray foam insulation air seals and never loses its R-value over time. When working with MPI Foam, your spray foam insulation has a lifetime warranty from the manufacturer that it will never settle once installed. 


Cost of Spray Foam Insulation vs. Cost of Fiberglass


Homeowners often choose their insulation type based on the cost. Generally, spray foam is more expensive than fiberglass insulation. In terms of spray foam costs, open-cell foam is less costly than closed-cell foam. Spray foam Insulation costs more due to its high R-value, which is an indicator of how well the insulation prevents heat from escaping or entering the home.

Spray foam insulation is known for its high ROI (return on investment) value. Homeowners who choose to install spray foam insulation may have to pay more upfront, but overall, they will reap the benefits of reduced energy costs. You will see a significant drop in heating and cooling costs.
