Has anyone used liquid flashing for window rough openings and still spray foamed and taped the jambs and head of windows?
We are installing European flangeless windows and have used zip liquid flashing for the rough openings. We’re planning to use air dam sealant on the interior. The window manufacturer wants us to use air dam on the exterior as well with and air gap between the two beads. Our ZIP Rep has said that the zip tape can be used to tape to the liquid flashing, and it seems less expensive and easier to use for our exterior. But the window manufacturer doesn’t like to mix tapes with liquid flashing. Has anyone used liquid flashing and caulk on interior but tapes on exterior? We would really like to just spray foam the cavity of the jambs and heads, and then use zip tape back to the sheathing…. but that’s not recommended by the window manufacturer.
