Where Louisiana Hit 114 Degrees
Spray Foam Insulation in Plain Dealing has a good argument behind it: the highest temperature ever recorded in Louisiana, 114F, was measured here on August 10, 1936. The town also logged -14F during the February 1899 blizzard. Plain Dealing sits in northern Bossier Parish about 8 miles south of the Arkansas border and 31 miles north of Shreveport, and its humid subtropical climate puts real demands on any house.
A small, old town
George Oglethorpe Gilmer and his son bought 5,000 acres here from the federal government in 1839 and named part of it after the family's Virginia plantation. The town was chartered on April 24, 1890. It had 893 residents and 424 households in 2020, down 12.0% from 2010. That adds up to a small, mostly older housing stock, along with farmhouses, mobile homes and outbuildings on the surrounding land.
What older rural houses need
In older homes around Plain Dealing we usually find thin attic insulation, open gaps at the tops of walls and around flues, walls with little or nothing in them, and raised floors with open crawl spaces. The order of work is the same as anywhere: seal the attic and insulate it to DOE's R-49 to R-60 target, fill walls with dense-pack blown-in, and get the crawl space dry with a vapor barrier before insulating the floor or the foundation walls.
Shops and barns
Farm properties here have metal barns and shops that turn into ovens in summer. Closed-cell foam on the steel insulates at around R-5 to R-7 per inch and stops condensation drip.

Plain Dealing Questions
Do you insulate mobile and manufactured homes?
Sometimes, depending on the home. Underbelly and roof work on manufactured homes is different from site-built houses, so we look first and tell you what is practical.
Is the drive to Plain Dealing extra?
Any travel is built into the written estimate, so the price you see is the price.
Can you foam a hay barn?
Yes, after the hay and equipment are moved out of the spray area.
What R-value should my attic have?
Louisiana's code treats the state as Climate Zone 2. For an existing attic with nothing in it, DOE recommends R-49 to R-60; with 3 to 4 inches already there, add R-38 to R-49.
