Inside the Slide: R-Value Changes with Temperature

Inside the Slide: R-Value Changes With Temperature Here is a chart we have referenced in presentations about attic insulation performance. It illustrates a couple of things: the difference between two seemingly similar loose fill attic insulations, and how their R values vary depending on how cold the attic is, and the interior house temperature is a warm 70F. Also it

Inside the Slide: Dew Point in a Wall

Here's a slide that we use in a lot of our presentations. As energy codes get more stringent, adding exterior wall insulation becomes a reality for more builders. So when does it make sense to add exterior insulation, and when can you skip it? This example is for a 2 x 4 wall in climate zone 4*. The perception: When
