Spray Foam Insulation
- Spray Foam Insulation (spray polyurethane foam (SPF))
- Superior alternative to traditional forms of insulation
- Is an air barrier and thermal barrier. Stopping air infiltration is the leading factor in reducing energy costs, and spray foam insulation is the best option for this. Because it is air barrier and thermal barrier, it is far superior to other forms of insulation.
- 2 types - Closed Cell and Open Cell. Each has distinct advantages in certain situations
- Can reduce energy costs by up to 50%
- Blocks all three forms of heat transfer:
- Conductive heat transfer - flow of thermal energy from higher to lower temperature region. An example of this is heat moving through the structure's walls, roof, and windows.
- Radiant heat transfer - Radiation from the sun is energy that is transferred in the form of infrared light waves. This most commonly occurs when the sun shines on your roof, is absorbed, and moves into the living space
- Convective heat transfer - The transfer of heat from one place to another by the movement of fluids or gases. This commonly happens inside structures and by stopping the air movement, convective heat loss will stop.
- More traditional form of insulation, most common, most cost effective
- Installing fiberglass batts can be an economical solution, if air sealing is done properly beforehand.
- Used extensively in new home construction and commercial applications
- Manufactured in batts, loose fill, and in a variety of R values
- More affordable
- Provides effective noise control.
- If installed properly, can help with energy efficiency of the space
- Made almost entirely from recycled newspaper
- Another cost effective way to help with energy efficiency in structures
- Can be blown into desired space and densely packed into cavities to help with air flow and r value
- More environmentally friendly than some other forms of insulation
