Attic Insulation

in Port St. Lucie & Stuart

Why Attic Insulation Matters on the Treasure Coast

Treasure Coast summers are long and humid, and your attic soaks up heat all day. Without enough insulation, that heat pushes down through your ceiling and your AC works harder to keep up.

A lot of homes here have had years to fall behind. Port St. Lucie grew fast in the 2000s, with more than a third of its homes built between 2000 and 2009, and most homes in Stuart date from 1970 to 1999. If your home is from either era, it’s worth checking whether your attic insulation measures up to the R-38 level recommended here.

Why the Treasure Coast Gets R-38

Most of South Florida falls in Climate Zone 1, where R-30 is the recommended attic level. St. Lucie and Martin counties fall in Climate Zone 2, where Florida’s building code requires R-38 in the attics of new homes. That’s the level we install on the Treasure Coast, so your attic matches the standard for where you actually live.

Your Treasure Coast Team

Our Treasure Coast team works out of our Port St. Lucie office and serves homes from Fort Pierce and Tradition down to Stuart and Hobe Sound. When we come out for your estimate, we’ll check your attic, tell you honestly whether it needs more insulation, and give you an exact price. Because we’re an HVAC company, we can look at your AC at the same time and tell you how the two work together.

Frequently Asked Questions: Attic Insulation on the Treasure Coast

What R-value do homes in Port St. Lucie and Stuart need?

St. Lucie and Martin counties are in Florida’s Climate Zone 2, where the building code requires R-38 in new-home attics. That’s what we install here.

Why is the Treasure Coast R-38 when the rest of South Florida is R-30?

Florida is split into two climate zones for energy code purposes. The southernmost counties are Zone 1 (R-30). St. Lucie and Martin counties are Zone 2, which calls for R-38.
