Spray Foam
See also: Spray foams (insulation)Spray foam is a type of insulation that is sprayed in place through a gun. Polyurethane and Isocyanate foams are applied as a two-component mixture that comes together at the tip of a gun, and forms an expanding foam. Cementitious foam is applied in a similar manner but does not expand. Spray foam insulation is sprayed onto concrete slabs, into wall cavities of an unfinished wall, against the interior side of sheathing, or through holes drilled in sheathing or drywall into the wall cavity of a finished wall.

Famous quotes containing the words spray and/or foam:
“Sovran of beauty! like the spray she grows,
Compassed she is with thorns and cankered bower.
Yet were she willing to be plucked and worn,
She would be gathered, though she grew on thorn.”
—Robert Greene (1558?–1592)
“Yet ere I can say where—the chariot hath
Passed over them—nor other trace I find
But as of foam after the ocean’s wrath”
—Percy Bysshe Shelley (1792–1822)
