For cutting rockwool insulation, retire your old bread knife and pick up a pair of these
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
Using theatrical smoke to illustrate air leakage pathways to customers and new employees
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.
