Spray Foam Insulation in Jamaica Beach, TX

Spray foam insulation in Jamaica Beach is mostly about raised beach houses. Wikipedia says the city was developed by the Jamaica Corporation as a 2,000-lot resort subdivision near a marina, and that with the growth of the second-home market almost all of its lots had sold by the 1970s. It sits on Galveston Island between the Gulf of Mexico and West Bay, bordered by Galveston on both sides.

Mostly part-time homes

The 2020 census counted 1,410 housing units in Jamaica Beach, and 60.9% were vacant at census time, a sign of how many are weekend homes and rentals. The median age of residents was 59.1. Part-time homes often sit closed up in summer heat, which makes a tight, well-insulated envelope even more useful: the house stays cooler and less humid while no one is there.

Under the floor

Homes here are typically raised, and the underside of the floor faces wind, salt air and spray. Batts held up with netting tend to sag and fall. Closed-cell spray foam applied directly to the subfloor between the joists stays in place, seals the floor and resists water.

Attics in beach houses

Many Jamaica Beach houses have the air handler and ducts in the attic under a roof that faces full Gulf sun. Foaming the underside of the roof deck brings that equipment into cooler air, while a sealed ceiling with deeper blown insulation is the lower-cost route where nothing mechanical sits in the attic. We compare both on the quote.

Code baseline

Galveston County is in Climate Zone 2A (OpenEI), where the Texas code summary lists R-38 for ceilings. For an existing attic, the Department of Energy suggests R-49 to R-60 if it is empty.

Storms

Jamaica Beach was hit by Hurricane Alicia in August 1983 and by Hurricane Ike in September 2008. After any storm that brings water into the house or under it, we check the insulation and remove what got wet before replacing it. Get a free estimate
