What Is the Best Attic Insulation for Florida?

Florida is known for its hot and humid climate. That’s why it’s crucial to have the right type of attic insulation in your home. You’ll appreciate how it will keep your home warm during the cool months and cool when the temperatures begin to climb. 

You might be asking yourself, what is the best type of attic insulation to have in Florida?  

The answer is simple: spray foam insulation. 

Spray Foam Is the Most Sufficient Attic Insulation 

Spray foam is known for its high performance in insulating an attic. It expands and hardens, filling empty spaces in your walls and sealing small gaps and crevices. Essentially, it creates a barrier that prevents hot air from escaping and moisture from creeping in. 

Open-Cell Spray Foam Insulation 

Open-cell spray foam is often used on the exteriors of buildings rather than the interiors, because it easily lets in moisture. It has a lower R-value, so it would require a large amount to produce any significant temperature differences in your Florida home. 

Closed-Cell Spray Foam Insulation 

Closed-cell foam insulation is more durable than open-cell, making it the better choice for building interiors. This type of insulation is better at preventing airflow and helps prevent mold growth by blocking water from seeping through. Closed-cell spray foam insulation completely seals the area being insulated, and consequently, takes longer to apply than open-cell insulation.   

Benefits of Spray Foam Insulation 

Choosing spray foam for insulation provides numerous benefits for your home. 

Energy Efficiency 

The U.S. Department of Energy estimates that around 56% of the energy used in your home comes from your HVAC system. With spray foam, you’ll find that your heating and cooling system works more efficiently throughout the year compared to homes using traditional insulation. 

Saves You Money 

Spray foam is 24 times less likely to allow air to leak through it than traditional forms of insulation. This means that temperatures in your home will stay more consistent, and your HVAC system won’t have to work as hard. As a result, you’ll save money on your energy bills. 

Spray foam insulation has saved customers an average of 50% or greater every year on their energy bills!  

Longer Lifespan 

Closed-cell spray foam has an exceptionally long lifespan, lasting 20 years or longer! This allows homeowners to continue benefiting from their initial investment. 

Eco-Friendly 

People have grown increasingly concerned with protecting the environment, so many people ask if spray foam insulation is eco-friendly. Indeed, it is. It helps reduce homeowners’ energy consumption and uses fewer consumable materials because of its longevity. 

Using attic insulation with a longer lifespan reduces your carbon footprint throughout the life of the material.  

Although spray foam outperforms other types of attic insulation, it’s worth mentioning other, more traditional, kinds. Blown-in fiberglass, blown-in cellulose, and fiberglass batt are all acceptable materials for attic insulation in Florida. However, you may find that they are not nearly as effective as spray foam at keeping hot air out and cool air in.
