Another question from down under.

I have been reading the chapter in the manual about cockpit installations. (Ch 16 in the fast build manual). On page 16-7 it specifies the seat back bulkhead should be made of “………1/2” white foam (or 3/8 Nomex honeycomb) with 2 Bid per side”. My quandary is as to whether this 2 Bid per side is required if I am using Nomex honeycomb, or is it only required if I am using foam?

What have other builders done?

Thanks again.
