PODCAST: Five Big Holes in your House That Suck Energy Outcomments (4) October 25th, 2011 in Blogs
An 1/8th inch crack along a window doesn't seem like much to worry about, but a 1/8th in. crack running the length of your house is like an open window. If that collective crack really were a hole, you could toss a cat through it. But because it is a crack, you can seal it with caulk.
Not all holes in the building envelope however, are cracks that can be sealed with a tube of caulk. Some of them really are big enough to toss a cat through. The Energy Star Thermal Bypass Checklist covers the most common gaps and holes in new houses, so this is a great place to start if you want to build a tight house.
Green Building Advisor has a collection of 56 detail drawings that will get you through the Energy Star checklist or help you build a tight house. Five of the details in that collection are discussed in this episode of the Lunch Pail podcast series by Mike Guertin and Peter Yost.
The holes discussed here are
- Behind a tub or shower unit
- Between an attached garage and living space
- In soffits above cabinets
- The connection of knee walls, roof, and floor in a 1-1/2 story house.
Two of these details are highlighted in the newest installment of Energy Smart Details, a back-of-the-book department in Fine Homebuilding magazine written by Martin Holladay.
