Spray Foam Insulation in League City, TX

Spray foam insulation in League City usually addresses the same problem: a hot second floor. Wikipedia shows League City growing from 45,444 residents in 2000 to 114,392 in 2020, so most homes are relatively new two-stories with the air handler and ducts in a vented attic. Those ducts sit in some of the hottest air in the house all summer.

Fixing a hot upstairs

Two approaches work. Spraying foam on the roof deck and closing the attic vents brings the ducts into conditioned space. Or, if the ducts are well sealed, we seal the ceiling and add insulation on the attic floor. We compare both in writing. Bonus rooms over garages and kneewalls next to attic space also leak and need sealing.

Owners and flooding

Census QuickFacts reports a 74.7% owner-occupied rate and a $360,000 median owner-occupied value. After Hurricane Harvey in 2017, about 6,000 League City houses flooded to some extent, according to a city councilman quoted by The Daily News.

Code baseline

Galveston County is in Climate Zone 2A (OpenEI). The Texas code summary lists R-38 ceilings and R-13 wood-frame walls in Zone 2. Many League City homes were built to those numbers, but code minimums do not account for ducts sitting in a hot attic or for leaky kneewalls.

After Harvey

Homes that flooded in 2017 often had their lower walls and insulation replaced. If you are remodeling again, closed-cell foam in the lower part of exterior walls holds up better if water ever returns.

Garage ceilings

Rooms over garages are common in League City two-stories. Closed-cell foam in the garage ceiling under those rooms seals and insulates in one step.
