I'm in the process of re siding my house. I just finished the soffet and pulled down the old siding. Behind the siding is a mess. They used the old style "cork" board and left huge gaps. Instead of patching all of it, I would like to cover the exterior with 1/2 insulation board and be done with it. Windows aren't an issue since I'm installing new one. My question is, the J channel in the soffet won't line up with the siding channel if I put on the insulation board - will that be ok?
