How Spray Foam Works
Resists Heat Flow
To maintain comfort in your home, the heat lost in winter must be replaced by your heating system and the heat gained in summer must be removed by your air conditioner. Insulating ceilings, walls, and floors decreases this heat flow by providing an effective resistance to the flow of heat. Heat flows naturally from a warmer to a cooler space. In winter, heat flow moves directly from heated living spaces to adjacent unheated attics, garages, and basements, or to the outdoors; or indirectly through interior ceilings, walls, and floors - wherever there is a difference in temperature. During the cooling season, heat flows from outdoors to the house interior.
Adding insulation beneath drywall in a typical wall configuration can increase the sound transmission coefficient STC rating. In most homes, walls between rooms are only marginally effective at blocking noise. Made of drywall and lumber alone, these interior or partition walls have poor Sound Transmission Class STC ratings. An STC rating is a number used to characterize the acoustic performance of a wall, floor or ceiling?the higher the STC rating, the less sound will be transmitted between rooms. By far the easiest and most economical method for controlling noise is to install insulation in the wall cavity. Click here for more info about sound control and insulation.
A vapor-resistant membrane (commonly called a vapor retarder) attached to batt or roll insulation decreases the possibility of moisture vapor condensing to water within the structure. Even though you need some moisture in the air you breathe, too much moisture in your home can cause problems. When moist air comes in contact with a cold surface, some of the moisture may leave the air and become liquid, or condense. If moisture condenses inside a wall, or in your attic, you will not be able to see the water, but it can cause a number of problems
Five Benefits of Spray Foam Insulation
1. Stop Air Flow
The number one reason your home loses energy, and you lose money, is ai flow (aka air leakage). According to the US Department of Energy, air leakage can contribute to as much as 40% of the energy cost to heat and cool your home.
2. Save Money
Spray foam insulation can help reduce heating and cooling costs by up to 50%
3. Improved Indoor Living Environment
Spray foam improves air quality, controls moisture issues, provides consistent thermal comfort and reduces noise
Spray Foam can noticeably reduce a building’s carbon footprint since less energy is required to head and cool the building.
5. Increased Value in Your Home
Spray foam insulation is an investment that will pay for itself in more than one way by recouping your investment in as little as 5 years

Think Energy Savings- and more.
Did you know that insulation saves commercial building owners more than $9.6 billion in energy costs annually? Insulation also reduces annual energy use in U.S. buildings by 12 quadrillion BTUs, roughly 15 percent of total U.S. annual energy usage. It also diminishes power plant emissions, cutting carbon dioxide by 780 million tons annually. (The figures include both commercial and residential buildings and are taken from the study "Green and Competitive: The Energy, Environmental and Economic Benefits of Fiber Glass, Mineral Wool, and Spray Foam Insulation Products.")
