Can an insulation system add structural strength?
Spray-applied closed-cell polyurethane foam is the only insulation material that adds structural integrity throughout the wall system. Testing conducted by the National Association of Home Builders (NAHB) Research Center and the Canadian Construction Materials Centre shows spray-applied polyurethane foam insulation between wood- and steel-stud wall panels increased rack and shear strength two to three times compared with standard stick-built components with glass fiber insulation when sprayed onto gypsum wallboard and vinyl siding, and increased racking strength when sprayed onto oriented strandboard (OSB).

The NAHB found that is also increase racking strength when sprayed onto oriented strand board (OSB).
Spray-applied closed-cell polyurethane foam (SPF) has been proven to add substantial structural integrity throughout the wall system. Testing2 shows SPF insulation installed between wood-and steel-stud wall panels increased racking (shear) strength two to three times compared with standard stick-built components with fiberglass insulation, when sprayed onto gypsum wallboard, vinyl and plywood siding, and oriented strand board (OSB).
