Glue the rim joist, caulk the gaps, and overhang the wall sheathing to tighten this leaky building assembly
Rinse off with cold water before the hot shower.
You can't simply go down to the hardware store and buy a box labeled air barrier
Doubling the square footage of a house while cutting the air leakage in half delivers extraordinary value
Whether using roof trusses or stick framing a roof frame, if you make space above the exterior walls, your energy performance will thank you.

Exterior insulation can create transition problems. Here are a few solutions
Vapor barriers cause a lot more harm than good in many parts of North America. Understanding vapor barriers begins with knowing what it means to be one
Thin foil can block massive amounts of heat transfer, but it needs a massive temperature difference to be effective. So, insulation sort of makes radiant barriers irrelevant.

For walls with a pre-applied weather barrier, make sure the tape is compatible with the WRB coating—or use a primer
Keep mechanical equipment within the envelope to improve the quality of houses and homes
The most effective (and easiest) time to detail the air barrier is during the framing stage. If it isn't specified during design, ain't no way the framers are gonna get it right.
18 Videos, articles, and animations showing you how to get through Section 1 of the Energy Star Thermal Bypass Checklist. It is about the continuity between various components of the air barrier system and the thermal envelope.
Framing a roof with I-joists over the existing roof makes a ton of room for insulation and offers a short lesson in vapor movement through assemblies
Condensation is when moisture in the air hits a cool enough surface to convert the vapor into water.
