Insulation & Air Sealing
Doubling the square footage of a house while cutting the air leakage in half delivers extraordinary value
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.
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.
Four ways to prevent ice dams in three types of roof, for two climates in one video. Boom.
Why insulating on top of a house is better than insulating inside
A big problem, for roofs in cold climates, but what causes it and how can you fix it?
A thermal break and solid backing puts the window on the outer face of a thick wall. Now, there's room on the inside window sill for cats and bowling trophies
