Established Homes in the DeSoto Parish Seat
Spray Foam Insulation in Mansfield is mostly about bringing established houses up to date. Mansfield is the seat of DeSoto Parish, home to the Mansfield State Historic Site, and part of the Shreveport-Bossier City metro area. Its population peaked at 6,485 in 1980 and was 4,714 in the 2020 census, down 5.7% from 2010. A town that peaked forty-odd years ago tends to have a housing stock built mostly before modern energy codes.
The housing picture
The 2020 census counted 2,153 housing units in Mansfield, 13.7% vacant, with a 2.3% homeowner vacancy rate. In homes of that era we expect attic insulation that has settled to a few inches, ductwork in the attic, uninsulated or partly insulated exterior walls, and raised floors with open crawl spaces. Those are fixable, and they are also where most of the cooling money goes.
A practical order
The attic comes first: seal the ceiling plane, then insulate to the Department of Energy's recommendation of R-49 to R-60 for an empty attic in Zone 2, or add R-38 to R-49 over existing insulation. Next is the crawl space if the house has one, with a vapor barrier, sealed and insulated floor, or full encapsulation with closed-cell foam on the walls if moisture is a problem. Walls come last, filled with dense-pack blown-in through small holes or sprayed with foam if they are open for a remodel.
Fixing up a vacant house
With about one in seven housing units vacant, some Mansfield houses are being renovated for sale or rent. An open wall or an attic stripped for a new roof is the cheapest moment to add foam.
Shops and farm buildings
DeSoto Parish has plenty of shops and metal buildings around town. Closed-cell foam on the steel keeps them cooler and stops the drip.
