I admit doing mostly small interior remodels, I havent used much engineered lumber, but at a jobsite next door to mine they are building a new home. They are currently framing and I noticed that they have wrapped all of their LVLs/PSLs (honestly I’m not sure how to tell the difference) with Typar. Is that just incase it rains or is that some requirement? Anyone seen or do that?

LVLs swell quite a bit in the rain once the wax has worked off. Just today we were admiring a 14" lvl used for a plank and it cupped 1/4" from a month in the on and off rain.

Ouch! Yeah, we've had quite a bit of rain around here. Just interesting to see the Typar built into the framing and not just a temporary thing.
Thanks!
Most of our LVL's come wraped in plastic from the yard. We leave the plastic on untill we are closed in so they don't get too wet and cause warpage or discoloration if we are going to leave them exposed. but typar could cause a lot of damage by not allowing the wood to dry out.
your call good luck.
Good info, thanks! These guys seem to be pretty sharp (as I originally posted, it's the neighboring jobsite...wish I was on a project that big!). I'll let you know what they end up doing when the close in.
The whole purpose of Typar is to keep rain out while letting vapor through--why would it not allow the LVL's to dry out?"This is a process, not an event."--Sphere
