    road trip jtrammel?

    how far apart are you two?

    this is a pretty common type duct/supply box with
    grill removed & gap sealed with mastic tape.

    fiber glass insulation filters air it doesn't stop leakage.

    materials to use are paint on mastic or mastic tape.

    tape failing is why mastic materials are best for
    duct sealing. there are paint on mastics & mastic tapes.

    best of luck.
