Long-time readers of GBA are familiar with Nate Adams. He’s the home-performance contractor who has published several opinionated blogs on GBA, including “The ‘Low-Hanging Fruit’ Fallacy” and “Hard Truths of Home Performance.”Nate Adams recently published a book called The Home Comfort Book.

For example, he notes, “Fixing comfort [problems] in consistently hot or cold rooms is a surprisingly difficult task.

What can a homeowner expect from a successful retrofit job? Adams writes, “Typical [energy] savings are usually in the $200-700/year range, even for advanced projects. … If you only want to save money, don’t embark on this process. It’s a waste of time and money.”Like many home-performance contractors, Adams is a fan of closed-cell spray foam. He writes, “We specify 3.5-inch closed-cell spray foam in many of our projects … Spray foam continually shocks me at how well it performs at only a few inches thick.” Elsewhere, he notes, “I became a big fan of closed-cell spray foam. It’s not cheap, but it consistently delivers great results… Start Free Trial Already a member? Log incenter_img This article is only available to GBA Prime Memberslast_img
