If you think your home is well insulated, you may want to do a double take

Insulation isn’t the most exciting or sexiest of home projects, but if you have plans to remodel any area of your home this fall or winter… it’s a great time to upgrade and take advantage of the energy efficiency that high performance insulation can provide.  According to a survey by the North American Insulation Manufacturers Association (NAIMA), 90% of existing U.S. homes are under-insulated.  That’s a whole lot of wasted dollars and wasted energy seeping out of attics, walls, basements and crawlspaces.

“People don’t see insulation, so they don’t think about it,” said Curt Rich, president and CEO of NAIMA.  “They see windows and doors so they think about those items.  The reality is that insulation has a three times greater impact on the average home’s energy and comfort than windows or doors do.”

Enter EPS, the only insulation you can use anywhere in the building envelope.  Insulation is a critical component and fast way to reach energy efficiency in residential applications.  A home should be properly insulated from the roof all the way to its foundation to reduce the excessive heat gain during the summer and heat loss in the winter.

Why all this loss?  This illustration from Green Building Advisor shows just how critical insulation is in roof, walls and floors, 75% over window and door air leakage.

Insulfoam’s ENERGY STAR® certified R-Tech lightweight rigid insulation panel is a versatile do-it-all insulation for the total building envelope.  Builders and homeowners can quickly and economically increase a home’s insulating power with these large lightweight panels that can be cut dimply and easily to fit virtually any space, are insect-resistant, and backed by a 20-year thermal warranty.

For example, many people discount insulation in basements and crawl spaces because they are near the ground. However, the connections from crawl spaces, foundations, and ground footings to the actual house are areas that need to be properly insulated and sealed against air leaks. This can account for 30% of heating and cooling energy loss for the average home.
