Customer build: a school bus turned RV, insulated with two TigerFoam 600FR kits.
The ribs, seams, and curves of a bus shell are hard to insulate with batts or board. Closed-cell spray foam expands into them and seals as it goes. Nearly R-7 per inch, ASTM E84 Class 1 Insulation. https://tigerfoam.com/order-products/spray-foam-kits/tf600fr-e84-fast-rise-spray-foam-insulation-kit/
Great work!
