Energy: Attic R Values
Last month we completed an insulation project in Secaucus NJ. When we first performed the home energy assessment, we found that the attic had next to no insulation. With only up to two inches in some areas with many gaps and voids, we were looking at an R value of about 4. By air sealing and then installing 12 inches of cellulose insulation throughout the space, we brought that R value over R 38, the 2009 Energy code standard. This home performance measure will save our customer an estimated 12% total energy savings on its own. The tip: insulate, insulate, insulate.
