Spray Foams (insulation)
Spray foam insulation is an alternative to traditional building insulation such as fiberglass. A two-component mixture composed of isocyanate and polyol resin comes together at the tip of a gun, and forms an expanding foam that is sprayed onto roof tiles, concrete slabs, into wall cavities, or through holes drilled in into a cavity of a finished wall.

Famous quotes containing the words spray and/or foams:
“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)
“This fantastic state of mind, of a humanity that has outrun its ideas, is matched by a political scene in the grotesque style, with Salvation Army methods, hallelujahs and bell-ringing and dervishlike repetition of monotonous catchwords, until everybody foams at the mouth. Fanaticism turns into a means of salvation, enthusiasm into epileptic ecstacy, politics becomes an opiate for the masses, a proletarian eschatology; and reason veils her face.”
—Thomas Mann (1875–1955)
