Roof framing, window options, and a mechanical advantage add up to lower bills and a higher quality home
Insulation & Air Sealing
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.
A collection of five videos on a Passive House Retrofit in Sharon, CT (climate zone 5) executed by Ben Bogie, Built to Last, LLC
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.
Why insulating on top of a house is better than insulating inside
Hands-on training with local pros at the largest construction event in the Northeast
A tight air barrier is the best way to build an energy-efficient house. Outside the sheathing are many chances to make it better.
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
