Subject: Segmented glass wall Nanawall.
I’m tasked with designing a remodel in a wood framed single family home. The owner wants to expand two opening in an exterior wall to 12 ft wide each. Both openings are to have nanawalls installed. After reading posts about engineers having trouble with nanawalls and header deflection, I’m questioning the wisdom of using a wood header at all. The owner is willing to use LVL or Glulam headers, but I’m not sure that is enough.
Has anyone had luck using wood headers with nanawalls? What advice would you give to an engineer designing for nanawalls for the first time?

I like to debate structural engineering theory -- a lot. If I challenge you on something, know that I'm doing so because I respect your opinion enough to either change it or adopt it.

I have called manufacturer's numerous times to let them know how unrealistic this can be. Even the wood shrinkage can be 1/16" Pretty much falls on deaf ears.
The techs who install them tell me they can be adjusted so they do not need such a tight tolerance.

I typically design Nanawalls and sensitive sliding glass doors as 1/4" deflection max.

Sounds like the LVL was not sized properly (among other things)

Wood is capable of providing the stiffness you require, however it is generally at a cost premium. When items are deflection sensitive I'm typically tempted to provide steel beams. Around here, a 3 ply LVL costs almost the same as a W12x19.
