What is Spray Foam?
Spray polyurethane foam (SPF) is a spray-applied plastic that forms a continuous insulation and air sealing barrier on walls, roofs, around corners and other surfaces. SPF insulation is resists heat transfer extremely well and offers a highly effective solution in reducing unwanted air infiltration.
How Does SPF Work?
Professionals combine two liquids to initiate a chemical reaction that creates foam. These liquids arrive at the job site in separate 55 gallon drums and are typically referred to as the “A” side and “B” side. After spray foam insulation is cured, it’s considered to be relatively inert. This means the chemicals are finished reacting.
According to the EPA, as much as 40% of a building’s energy is lost to air infiltration.
Air leaks that waste energy and drive up utility bills can be filled with spray foam. Spray foam expands in place to insulate and seal the spaces seen and unseen. This unique application process allows spray foam to create a layer of protection that provides a consistent air seal for any wall, roof, ceiling, or floor.
Applying closed cell spray foam in wall cavities improves building durability.
This is due to its ability to conform and adhere to the surface upon which it is sprayed. A wall with spray foam insulation is better able to maintain its shape under duress than a wall assembly without spray foam.
