- Insulation carries a rating called an R-value that is an indication of its resistance to heat flow. The higher the rating, the more effective the insulation. Suggested home insulation levels vary depending on climate, but R-values of 30 to 40 are recomended in many parts of the United States. Polyurethane insulation systems work well in walls, under floors and in attics due to its high R-value per inch of thickness. The different forms of polyurethane insulation have different ratings, so always read the label information.
- Polyurethane foam insulation is versatile for both exterior and interior use. The sprayed-in or foamed-in types adapt well to irregular spaces by conforming to any shape as they expand and set. Once the polyurethane insulation conforms to the space, it retains its form regardless of extreme temperature fluctuations.
- Polyurethane insulation acts as a variety of barriers within your home. As an air barrier, it creates an entire building envelope by blocking air movement in and out. This aids in energy efficiency by reducing pollutants, dust and moisture. An effective air barrier reduces energy costs thanks to reduced heat loss during the cooler months and reduced cool-air loss during warmer months. As a sound barrier, it creates a comfort zone to eliminate busy street activity and noisy neighbors.
- The U.S. Department of Energy awards qualified new residences that meet the energy-efficiency criteria with the Energy Star. These homes need to be at least 15 percent more energy-efficient than homes built to the International Residential Code of 2004. Using polyurethane insulation in the walls, attic and under the floors of your home creates an energy envelope that will aid in achieving an Energy Star award.
