A Growing City Below the County Line
Spray Foam Insulation in Sebastian serves Indian River County's largest city. Sebastian had 25,054 residents in 2020, up 14.3 percent from 2010. Settled in the 1870s and founded in 1882 as St. Sebastian, it sits just south of the Brevard line. Nearby Pelican Island became the first U.S. National Wildlife Refuge in 1903.
Housing
Sebastian's homes range from older houses to newer subdivisions, and many have block walls, attic air handlers and slab floors. Older ones often have thin, settled attic insulation and unsealed ceilings. Newer ones have better baselines but still have gaps at hatches, lights and garage ceilings.
Rain
Sebastian averages about 52 inches of precipitation a year, with September the wettest month at 9.1 inches. Heavy rain finds roof weak spots. We check for leaks before recommending insulation.
Storms
The 2004 hurricanes and later storms damaged roofs along this coast. Homes repaired after a storm sometimes kept insulation that had been soaked, so we check for staining and compression.
Code
OpenEI lists Indian River County in Climate Zone 2A. Florida's 2023 energy code sets R-38 for ceilings in Zone 2, and ENERGY STAR suggests R-49 for a bare existing attic.
FPL
If your home is on FPL, its ceiling insulation program standards list a $220 rebate when existing insulation is below R-8 and a participating contractor does the work. Check FPL's current terms.
Riverfront and inland
Homes near the Indian River Lagoon see more salt air. All of them deal with heavy September rain, and all get the same leak check before we recommend anything.
Comfort all day
For anyone home most of the day, steady indoor temperatures make the biggest difference, and attic sealing and insulation are among the most affordable ways to get there.
Additions
Screen rooms enclosed as Florida rooms usually have thin roofs with little insulation; foam under the roof or insulated panels can make them usable in summer.
