Insulating Homes in Lantana
Spray Foam Insulation in Lantana serves a small, dense town on the Lake Worth Lagoon. Lantana covers 2.97 square miles, about 0.60 of it water, and its 2020 population density was 4,860.8 people per square mile. It was incorporated on July 20, 1921, covering one square mile with 100 residents, when oyster gathering and marketing was the leading industry.
Mid-century homes
The 1950s account for 21.2% of the housing stock and the 1960s for 17.7% (ACS via Point2Homes). Mid-century block homes usually have low-slope roofs, small attics and very little insulation by today's standards. Where the attic is reachable, sealing and blowing in is the best value. Where it is too shallow, closed-cell foam on the underside of the roof deck or during a reroof may be the only practical way to add R-value.
Many rentals
Owners live in 52.9% of occupied homes; the rest are rented (Census ACS 2020-2024). For landlords, attic sealing and blown-in usually offer the best return per dollar, and FPL's ceiling insulation rebate may apply where existing insulation is below R-8.
Close to the water
With water making up a fifth of the town's area, humid air is a constant. Sealing attic leaks and duct connections keeps that air out of the living space and out of the AC's return.
Reroof timing
Many Lantana homes are due for a roof sooner or later, and a reroof is the easiest time to deal with a shallow attic. With the old roofing off and the new deck going down, foam can go on the underside of a clean, dry deck once the roof is dried in, or rigid insulation can be added above it by the roofer. Talk to us before the roofer starts so the work lines up.
