    When spanning beams like that I would have preferred an LVL also. Probably would have gone for a 300x63 LVL though.

    Why put in more than you have to?
    According to the tables he's alright, and I'm sure there's plenty of margin before any failure. At least 2:1 I'd imagine, but probably a whole lot more than that.

    I just like to have very limited deflection over openings like that. Plus without the table that was my first guess. If I had a proper look at it and the 240 was less than 8mm deflection long term, I would have went for it.
