Flex Seal to Air-Seal Framing

Willyf16 | Posted in Green Products and Materials on

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.
