Recommended sheathing tape width?

Norman Bunn | Posted in Energy Efficiency and Durability on

How wide should sheathing tape be to provide a quality air seal on OSB in CZ 3A? I am looking at 3M 8067, but am open to other options.

    Norman,
    Taping OSB is tricky. I would use tape that is at least 3 inches wide if you can find it. Four inches wouldn't be too wide.

    Try some first. I find that nothing stays stuck to regular osb for very long. My most recent experience is using 3m 8087.

    Per info I got on the GBA site, I plan to pre-treat the OSB with 3M 90 contact adhesive, which has shown to greatly increase the grab of tapes on OSB.

    For what it's worth, 3M 8067 sticks tenaciously to Advantek sheathing.
