According to a new study released by the North American Insulation Manufacturers Association (NAIMA) roughly 90% of homes in the United States are under insulated. The study drew on numbers derived from the 2009 Residential Energy Consumption Survey and other research completed by Lawrence Berkeley National Laboratory and Boston University. Speaking about the study, Dr. Jonathan Levy, professor at the Boston University School of Public Health, said; “If all U.S. homes were fitted with insulation based on the 2012 International Energy Conservation Code (IECC), residential electricity use nationwide would drop by about 5 percent and natural gas use by more than 10 percent.”
According to the Department of Energy, heating and cooling costs comprise more than 44 percent of the energy consumed in a single family home. Homes containing adequate levels of insulation help consumers achieve lower energy costs and reduce the amount of harmful carbon emissions created as a result of electricity generation.
While Polyiso foam insulation is the market leader for commercial roofing applications, it can also be used in residential wall applications. When properly specified and installed, Polyiso sheathing insulation offers one of the best values available for residential construction. Benefits include:
- A residential wall system with a high R-value increases the energy efficiency of the home and significantly reduces heat loss.
- A reduction in air infiltration and exfiltration, which increases the overall performance of the wall and reduces heat loss.
- A reduction in the risk of water condensation/intrusion, which increases thermal and structural performance and reduces builder call backs.
- Insulation over the entire framing members, known as a continuous insulation system, which reduces the overall home energy loss.
- Increased confidence with an assurance the home builder is providing a quality product.
- More confidence that your home was built with state-of-the-art energy-efficient techniques.
PIMA has also recently published a “Wall Insulation Knowledge Base” that includes dozens of technical bulletins and articles on topics such as code compliance and environmental performance regarding Polyiso insulation wall assemblies. The knowledge base can be accessed on the PIMA website here.
