Rinse off with cold water before the hot shower.
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.
Using theatrical smoke to illustrate air leakage pathways to customers and new employees
Exterior insulation can create transition problems. Here are a few solutions
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.

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.
