    Default Joist question

    Is this type of joist rated for exterior exposure. Several joists were sistered under a hot tub and the water from the tub was deteriorating the joist. But,I was curious what everyone knows about these.

    Thanks

    Wow, all kinds of problems there....

    Leaking tub of some type

    Boring in the lower 1/3 of the joists

    And no, I'd say that's not an 'outdoor' piece of lumber. However, I think the decking might give out before the joist.... kind of a race, really

    That's a glue-lam of sorts, definitely not intended for outdoor use... under a hot tub.

    Second PDF posted by Billy says PSL for exterior use.

    Thanks for the info. I spoke to a rep today and he said they have to be wolmanized for exterior use. Also the hole drilled is not an issue. Thanks for the web site, very helpful.

    If those drilled holes are within 2 inches of the bottom of those framing support members its a violation of IBC 2308.10.4. (2007 CBC same)

    Jerry,
    What if the joists are sistered, does that negate the detrimental effects of holes being drilled in the lower third.
