What Is The Best R-Value For Exterior Wall Insulation?

Insulating the attic is a must in Florida, but you could be doing even more to regulate your home’s temps. For peak comfort and energy savings, many homeowners in the area will add extra insulation to their exterior walls for complete coverage. Sounds like a great idea, right? Well, it only works when you use insulation materials with the highest R-value. Don’t worry, we’ve made things easy for you!

Keep reading to find out what the best R-value is for exterior wall insulation before reaching out to Foam Bear Tampa for top-notch spray foam insulation near you.

The Magic Number For Insulating Exterior Walls In Tampa

Because your exterior walls are exposed to direct sunlight, you’ll need the best insulation you can get your hands on. But in order to do that, you need to know what R-value you need to meet for guaranteed optimal results.

Exterior walls for homes in Tampa need an R-value of around R-13 to R-23. The exact value depends on a lot of things, like the exact location of the property, what the building material is made of, and so on. But in most cases, homeowners can get by with an R-value of 13.

How Do Experts Determine Ideal R-Value In Tampa?

If you’re looking to get more precise for an efficient upgrade, you can become more familiar with the many factors that make up your home’s ideal R-value for exterior wall insulation in Tampa:

  • The local climate
  • Wall thickness and density
  • Your available budget
  • Tampa building codes and regulations
  • The type of insulation material
The insulation you choose for your exterior walls should also account for the occasional storm or hurricane, considering that the outside of your home will inevitably get hit with high winds and rain.

Does Rockwool Or Spray Foam Have A Better R-Value?

R-value is the primary way to measure thermal and heat transfer resistance between insulation materials. So, then, which type of insulation has the better R-value between rockwool and spray foam for optimal performance? Your search is over, because we have the answer for you right here! After learning more about which is the better choice for you, reach out to Foam Bear Orlando today to ask for a free estimate on quality spray foam insulation near you.

What Is Rockwool? (Not the Insulation You Were Hoping For)

There is a good handful of homeowners in Orlando who have their eyes on rockwool insulation as a potential choice for their property. What is it about rockwool that has them interested? Also known as stone wool insulation, rockwool is made up of a composition of rocks like basalt and slag.

Many people believe these naturally occurring rocks to be an environmentally-friendly way to insulate their homes, but the R-value of rockwool insulation is practically half of what spray foam insulation offers.

Did You Know? Rockwool Insulation Can Cause:

Respiratory problems

Skin and eye irritation

Polluted air in the home

Possible carcinogen

R-Value Showdown – Rockwool vs. Closed-Cell Spray Foam

We already revealed that the R-value of rockwool insulation doesn’t quite match that of spray foam insulation, but let’s take a closer look at the numbers so you have a better idea of the vast difference in thermal resistance between these materials:

Closed-cell spray foam has an R-value of R-6 to R-7 per square inch.

Open-cell spray foam has an R-value of R-3.5 to R-4 per square inch.

Rockwool insulation has an R-value of R-3.1 to R-4 per square inch.

You can see that rockwool and open-cell foam are fairly similar in R-value, but don’t forget, spray foam comes with additional traits like air-sealing and moisture resistance that competing materials don’t have. And for the highest R-value, nothing beats the more dense closed-cell spray foam variety, which makes it a popular choice for Orlando homes.

Bonus Round: Comparing Additional Qualities

Spray foam insulation can do more than your typical insulation materials, mostly thanks to its ability to grow and expand upon application. You won’t find these extra benefits in rockwool insulation!

Here’s what else spray foam insulation can do for your Orlando home:

  • Create an effective air barrier with an air-tight seal that prevents air leaks.
  • Completely repel moisture to prevent mold and mildew inside the home.
  • Provide a longer lifespan for a long-term investment and cost savings.
  • Save you time with a simple and stress-free installation.
Rockwool can become easily damaged in Orlando, which is why it’s not considered as cost-effective as spray foam. Learn more about how spray foam insulation is a smart long-term investment in our in-depth guide!
