Attic Insulation in Key West

and the Lower Keys

Why Attic Insulation Matters in Key West

In Key West, your AC runs almost every day of the year, and your attic soaks up the sun the whole time. Without enough insulation, that heat comes down through your ceiling and your AC has to work harder to keep up.

Key West also has some of the oldest homes in Florida. The median home here was built in 1968, and about one in five dates to before 1940, long before today’s insulation standards existed. If your home is one of them, there’s a good chance your attic could use more.
