Sealing bottom of exterior roof wool insulation
We will be installing 2″ of rock wool insulation on the exterior of our new house with a 3/4″ rain screen. How would the bottom of the rock wool be sealed from insects, etc. since it is only semi rigid? Should I run a 1 x material cut to 2″ wide around the piermeter of the house and set the rock wool on top of this? Or get a J shaped piece of flashing to set the rock wool into? I do not want to just leave it open. Thanks.
