I have new Microllam LVL beams in place on a new build garage, now I'm told my trusses are running behind for delivery, possibly another 3-4 weeks, we have rain and snow coming and the beams will be exposed to the weather longer than expected. Looked online and the only info I can find is that the beams should not be exposed to the wet weather, I can't even find a phone number of the manufacturer so I can get a little tech support on how weatherproof these beams really are. Thinking about wrapping my cripples and beams with Tyvek to keep them dry but I wish I could contact the manufacturer to see just how critical keeping these beams dry really is. Anyone have any info on this subject?
