Old Houses on Bayou Lafourche
Spray Foam Insulation in Thibodaux deals with a town that has been growing along Bayou Lafourche since the early 1800s. A trading post called Thibodeauxville was there by 1808, near where Bayou Lafourche and Bayou Terrebonne meet, and the town was incorporated in 1830. Thibodaux is the Lafourche Parish seat and home to Nicholls State University, and it had 15,948 residents in 2020.
Older homes
Thibodaux has a large stock of older houses near the bayou and downtown, many raised off the ground with wood floors and shallow attics. These houses were built to breathe, and they leak a lot of air. The usual plan is to seal the ceiling and blow the attic to depth, and to insulate the underside of the floor with closed-cell foam, which blocks humid air without trapping water the way sagging batts do.
Rental and student housing
With Nicholls State in town, many Thibodaux homes are rentals. Owners often want work that is durable and low-maintenance. Foam under raised floors and blown-in in attics both last without much attention.
Climate zone and code
Lafourche Parish is in climate zone 2A, and Louisiana's 2021 code summary lists R-38 for ceilings and R-13 for wood-frame walls in new homes. 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.
Termites
The Formosan termite is a serious problem in south Louisiana. We leave inspection gaps where foam meets piers and foundation walls.
