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.

    I discovered
    the colors in the wall that woke
    when spray from the hose
    played on its pocks and warts....

    The new white flowers that are beginning to shoot up about now.
