Wall Insulation in Florida

Most older Florida block homes have little or nothing in the walls. Furring-strip foil systems and injected foam make a real difference in west- and south-facing walls that bake all afternoon.

Florida block walls: the forgotten surface

The majority of Florida homes are concrete block. Block has almost no meaningful R-value — around R-0.2 per inch. In a typical older block home, the wall assembly is: block, furring strips, drywall, and air. A west-facing wall in that configuration is radiating heat into the room until well after sunset.

Furring-strip reflective systems and injected foam both work in that cavity, install from the interior, and don't cost you floor space.

Retrofit dense-pack for frame walls

For wood-frame walls with empty cavities, dense-pack cellulose injected through small access holes fills the cavity completely, including around wiring and blocking, and provides real air-leakage reduction as well as R-value. Holes get patched and painted. It's a one-day job for most homes and it's dramatically less invasive than people expect.

New construction wall assemblies

For new builds we install to the approved energy calculation — batt, blown-in-blanket, or spray foam in the cavity, plus continuous exterior insulation where the assembly calls for it. Continuous exterior insulation is the single most effective wall improvement available because it breaks the thermal bridge through every stud, and studs are typically 20 to 25 percent of a wall's area.

Sound as a side benefit

Wall insulation that was bought for energy reasons almost always gets appreciated for acoustic reasons. Interior walls between bedrooms, around bathrooms, and around home offices are inexpensive to insulate during construction and impossible to appreciate until you've lived in a house without it.
