Also known as Spray Polyurethane Foam or SPF, is an insulation that is applied as a liquid and then expands, forming the foam. SPF can be either open or closed cell in structure, depending on the density desired. The density will depend on the specific project for which it's being utilized and on its intended purpose and/or desired goal. Special equipment is needed to apply the SPF as well as many months of technical training.

Open cell is spray applied polyurethane foam that expands 120 x its liquid volume providing superior insulating, air sealing and sound properties. Open cell foam utilizes water as a blowing agent trapping air in the structure of the cells. Open Cell SPF has an R-value around 3.5 per inch and typically uses water as the blowing agent. Open cell foam like closed cell works on all three principles of heat transfer. This is what makes foams superior insulators. As well as a great thermal insulator open cell will provide for excellent sound reduction. Open Cell SPF cells are not completely closed and air fills all of the 'open' space inside the material. In Closed Cell SPF, all of the tiny foam cells are closed and packed together. They are filled with a gas that helps the foam rise and expand and create a greater insulator.
Is the term given to thermal resistance to heat flow. The higher the R-value of an insulation product, the more effective the insulation properties. 1.8-2 pound polyurethane foam has the highest R-value of readily available insulation used in homes and buildings
Polyurethane is a closed-cell foam insulation material that contains a low-conductivity gas in its cells. As a result of the high thermal resistance of the gas, spray polyurethane insulation typically has an R-value around R-5 to R-6 per inch. In comparison, blown fiberglass typically has an R-Value of only R-2 to R-4 per inch.
The flow of thermal energy through a substance from a higher to a lower temperature region. Foam thermoset plastics block conductive heat transfer due in part to having very loose molecular bonds; In addition the cells of the installed spray foam are either filled with air in the case of open cell foam or 245fa in closed cell foam.
The process by which heat energy in the form of light (usually IR unless the substrate is hot enough to glow in the visible range) is emitted more strongly by warm surfaces and absorbed by other materials especially those of low IR reflectivity (think matte black finish). Radiant heat transfer does not require a medium. Thermoset foams, such as spray foam insulation, have the ability to reflect radiant heat. This is due to the reflective (shiny, in terms of IR) surfaces within the cell structure of the foam.
Heat which is created elsewhere that is transported by means of a fluid, such as water or in our case air. Spray foam insulation's most important attribute is the ability to air seal creating a custom airtight envelope within the building structure. The added benefit to air sealing is the ability to block convective heat transfer from interior to exterior during heating months and vice versa during cooling months, as the heat cannot escape through gaps in the buildings envelope without the aid of air movement from infiltration as a means of transport.
Spray foam insulation saves on energy costs and lowers utility bills. Studies by the US Department of Energy show that 40% of a home's energy is lost as the result of air infiltration through walls, windows and doorways. Buildings treated with spray foam insulation insulate as much as 50% better than traditional insulation products.
Insulation that is sprayed in buildings protects against moisture, which provides the benefit of reducing the chance of harmful mold and mildew. Eliminating mold growth reduces the likelihood of rotting wood in a home, and allergic reactions to mold spores.
In addition to building temperature and moisture control, spray foam insulation is often used to reduce noise. Foam insulation serves as a barrier to airborne sounds, and reduces airborne sound transfer through a building's roof, floor and walls.
In the United States, businesses and homes treated with spray foam insulation often qualify for state and federal tax deductions.
