A foam material is made through a spray process by combining a polyol with a pre-reacted isocyanate. The pre-reacted isocyanate contains an isocyanate pre-reacted with a prefoaming agent, such as a second polyol. The second polyol might be the same or different than the first polyol. Once combined in the presence of a blowing agent, the polyol and the pre-reacted isocyanate form a foam material, such as a polyurethane foam. The foam material is particularly well suited for insulating surfaces. In one embodiment, for instance, the foam is formed and applied on site.
