Integrating continuous insulation with traditional building methods is much easier than it sounds.  Take tar paper for example.  Tar paper is historically the most common water resistive barrier (WRB) for residential construction.  Typically after flashing is installed, the tar paper is shingled up the wall--each sheet overlapping the sheet below--to create a continuous drainage plane.  To integrate continuous insulation with this system is pretty simple: just add continuous insulation!  Simply install the insulation boards according to the manufacturer’s instructions on top of the tar paper layer, and you’re done,

Often times continuous insulation can be intimidating to designers or installers, but its use is quite straightforward, and the benefits are abundant, as we’ve covered in this series of articles (see links below).  As always, there are many more in-depth resources available on continuousinsulation.org, and don’t forget to watch this short video that illustrates the ease of adding continuous insulation to your project:
