Rockwool Comfortboard 80 bottom edge details
I’m installing 1.5 inches of Rockwool insulation on the outside of my house. I have been looking for details on how to finish the bottom border.
Looking at the diagrams from Rockwool, they always show a continuous layer of rockwool extending into the ground. I will be stopping my insulation at the sheathing/foundation joint. I am doing a fairly typical install, using 1×3 furring strips and Cora vent SV-5 for the bug screen on the rainscreen part. The detail I have not seen on any installation is what to to directly under the bottom boarder of the 1.5 inches of insulation. Is it ok to leave that open since no one will it as it will be hid behind the siding and bugs/rodents do not like it? or do I need to run a length of L flashing under it to protect the bottom edge? Thanks in advance.
