In the average house, heat is escaping through every leak, draft, and opening—and that’s like throwing money out the window. Good insulation and weatherproofing can make your home run more efficiently, guard it from the elements, and lower those ever-rising heating bills. Popular Mechanics makes the entire process simple, with hundreds of color photographs, diagrams, and illustrations that teach you how to insulate from top to bottom. Find out how to reflect heat from a radiator, seal gaps around doors, double-glaze windows or add weather-stripping, install vapor barriers, ventilate properly, and block out the chill in attics and between rafters. You’ll feel the difference, and see the savings, almost instantly.
This book is a mix of good illustrations, poor editing, and mediocre information. I think, perhaps, this book was spliced together from other Popular Mechanics publications as there's weird formatting and unusual language (page 52: Seal gap with mastic and wooden quadrant...). It was published in 2006 and has no information on spray-foam insulation or foam roof systems. I have a heating/cooling issue and found no solutions here. I found no explanation as to how ventilation works in tandem with insulation - as there seems to be opposing instructions in this book. I learned some things here but need to do more research.
