Spray Foam Insulation in Lakeland, FL

Spray foam insulation in Lakeland is about one thing above all: keeping heat and humid air out. Lakeland's normals show a July average high of 92.1F and a record of 105F, and June and July each bring close to 9 inches of rain. The air conditioner runs most of the year, and every leak in the ceiling, ducts and walls lets in hot, wet air. We seal those leaks and insulate the spaces that need it, using open-cell or closed-cell spray foam where it makes sense and blown-in insulation where it is the better buy.

Florida code and climate zone 2

Florida's 8th Edition Building Code, Energy Conservation, took effect on December 31, 2023, and Polk County is in climate zone 2A. The Insulation Institute's summary lists R-38 ceilings, R-13 wood-frame walls and a lower value for concrete block (mass) walls in zone 2. For existing attics, the Department of Energy suggests R-49 to R-60 if empty, or adding R-38 to R-49 over 3 to 4 inches.

Lakeland Electric attic rebate

Lakeland Electric lists a $300 rebate for residential customers who upgrade attic insulation from R-19 or less to R-30 or more. You schedule a Lakeland Electric inspection before work starts, and the rebate is limited to one per location. You can use any local insulation contractor.

Spray foam insulation contractors: what to ask

When you compare spray foam insulation companies or insulation contractors near you, ask each the same questions. Which areas get foam, and which get blown-in? Open cell or closed cell, and how thick? What R-value will each area reach? Where are the ducts, and will the attic be sealed or vented? How long must the house be empty while foam cures? Written answers tell you more than a per-square-foot price over the phone.

Closed cell vs open cell

Open-cell foam is soft, expands to fill cavities completely and costs less, at about R-3.5 to R-3.7 per inch by HomeGuide's numbers. It is the usual choice on roof decks for sealed attics. Closed-cell foam cures dense, slows vapor and resists water, at R-5 to R-7 per inch. It is the pick for metal buildings, block walls with shallow furring and anywhere wetting is possible.

Spray foam insulation cost

National guides put installed spray foam at about $1.50 to $5.00 per square foot (HomeGuide), with closed cell at $3.00 to $5.00, and whole-house work at $8,000 to $20,000 (HomeGuide) or $10,000 to $30,000 (Fixr). Attic, wall, blown-in and metal-building work have their own ranges on the service pages, and each one names its source.
