Insulating your home

Insulation—silently hidden in your walls, no moving parts to fix—is a material you probably spend precious little time thinking about. Then along comes subzero (or sweltering!) weather, a three-digit utility bill or chilly drafts, and you start thinking about it a lot! At home, you ponder whether it’s worth the time and expense to add it to your ceilings, walls and basement. At the store, you ponder which type, thickness, width and density to buy. And when you install it, you wonder just how good is “good enough.”
