Anyone tried using Flex Seal for air sealing framing prior to insulation? Vs DAP air stop and Knauf is difficult to get ahold of.

    I always thought of flex seal for emergency use and not something to permanently seal anything.

    Hi Willy,

    The general consensus appears to be that it’s not a great plan. You should read through this Q&A thread . It addresses a related question, and a number of readers weigh in with alternative product suggestions.
