Most energy-conscious people know that when it comes to home insulation, more is better. But homeowner Alex Cheimets is literally thinking outside the box with his "superinsulation" plan.
Rather than just blow in a few more inches of standard cellulose insulation in his attic, Cheimets is in the throes of an ambitious project to seal the outside of his home with two layers of insulating foam board.
Known in building industry as a superinsulated home, the foam blanket will keep hot (and cool) air in, and also block the cracks that let in outside air. If all goes as hoped, he will cut oil consumption by 70% at his 80-year-old, two-family home in Arlington, Mass.
