Project Spotlight: Large Residential Home

August 13, 2026

This large residential property in East Feliciana Parish required an insulation system built for long-term performance—not just short-term comfort.

With a substantial home and property to maintain, the homeowner wanted an insulation solution that could help improve efficiency, comfort, and durability while allowing more time and attention to be spent on the things that matter.

Project Challenge

The home required insulation across multiple areas to create a more complete and consistent thermal envelope. The goal was to improve energy efficiency and indoor comfort while reducing heat transfer and providing an insulation system designed for long-term performance.

Thermo-Guard Solution

Thermo-Guard installed a full open-cell spray foam insulation envelope throughout the designated areas of the residence. The project included 3" average open-cell spray foam across 3,311 sq. ft. of walls, 6" average open-cell spray foam across 4,269 sq. ft. of roofline, and 3" average open-cell spray foam across 1,035 sq. ft. of ceiling deck at the rear porch/carport area. Total spray foam coverage was approximately 8,615 sq. ft.


Results

  • Created a more complete and consistent insulated building envelope.
  • Reduced uncontrolled air movement through insulated walls and roofline.
  • Helped improve year-round indoor comfort.
  • Reduced the amount of heat entering the home through the roofline.
  • Added a long-term insulation solution designed to help the homeowner spend less time worrying about a warm house and high energy bills.

Technical Note

Open-cell spray foam typically provides approximately R-3.5 to R-3.9 per inch and expands to fill irregular areas and gaps within the building envelope. The 6" roofline application provides approximately R-21 to R-23 of insulation value, while the 3" wall application provides approximately R-10.5 to R-12.


Quick Takeaway

For a large home, a complete spray foam envelope can provide the long-term comfort, efficiency, and air sealing needed to make the property easier to maintain—and let the homeowner focus on more important things.
