Spray Foam Insulation in Upper Grand Lagoon, FL

Spray Foam Insulation in Upper Grand Lagoon covers one of the busiest residential areas on the beach side of the bay. This census-designated place had 15,778 residents in the 2020 census, up from 13,963 in 2010, and nearly half of its 15.91 square miles is water, according to Wikipedia. That means a lot of homes on canals, the lagoon and the bay, with all the humidity that comes with living on the water.

Year-round and part-time

The 2020 census counted 8,896 housing units in Upper Grand Lagoon, 24.4% of them vacant, with 6,722 households. Vacancy here includes second homes and units between renters. For owners who are not here full time, the insulation has a different job: keeping humidity under control while the AC is set back or off. Leaky attics and floors let damp air in, and a closed-up house can get musty fast. Air sealing the attic and floor matters as much as adding R-value.

Newer homes, newer problems

With the area growing, we see a lot of homes built in the last couple of decades. Insulation levels are often decent, but ducts in hot attics leak, bonus rooms over garages run hot, and recessed lights pull attic air down into rooms. Sealing the duct boots and light fixtures, foaming the floor and kneewalls of bonus rooms, or sealing the whole roofline with open-cell foam are typical jobs. For older homes, sealing the ceiling and blowing insulation to depth is usually the best value.

Code and recommended levels

Bay County is in ASHRAE Climate Zone 2A. Florida's 2023 energy code lists R-38 for ceilings and R-13 for wood-frame walls in Zone 2, and the Department of Energy recommends R-38 to R-49 for a Zone 2 attic that already has three to four inches. Most existing attics we see here fall between those marks.

Waterfront floors

Homes raised near the water have floors exposed to damp air underneath. Closed-cell foam on the underside of the subfloor is the most durable fix.

Canal-side houses and storage

Many homes along the canals and the lagoon have garages or storage areas at ground level with living space above. The floor between them is where heat and humidity move into the house, and where car exhaust and garage odors can find their way up. Closed-cell foam on the underside of that floor seals it in one step. Owners who store boats, tools or outdoor gear in a garage under the house often ask us to insulate the garage walls too, which is worth pricing if the space is also cooled.

We also see older lagoon homes where previous owners added a room or enclosed a porch. Those additions often have little or no insulation in the walls or ceiling, and they are usually the hottest rooms in the house.
