On the outside of the home we used DOW rigid foam that has a r-value of 5. This is important because it insulates the outside of our stud wall. This will help with the transfer of cold through the actual 2x6 stud.

Have you ever seen a home on a cool morning and you can see ever stud cavity? What you are actually seeing is the stud being warmer than the stud cavity and the frost is melting in that area. What we are trying to do is create a balance in that stud cavity so we don't have condensation forming when we reach the critical dew point. With the stud being warm and the cavity being cold this is a perfect situation for this to happen.

Before we install the windows we will wrap the entire home in Tyvek house wrap. The Tyvek house wrap will stop any wind or water molecules from penetrating through our building envelope.
