That is a question for the installer I have not had experience with that subfloor.

It depends on the Advantech product. You have random width wood which much indicates a glue assist is MINIMAL requirement. The installation instructions will tell you (you have to down load them and read them off of Lumber Liquidators website).

Advantech is one of the name brands of wood substrates. Some of them can handle glue. Others cannot. I'm not excided about a fibreboard being used with nails.

Again, the installation instructions will list what is allowed and what isn't. But beware. Bella Cera is a 'private label' created by LL. LL brings in product from DOZENS of different manufacturers and all have their own issues...but the installation instructions are simplified. That means they do not always relate directly to the floors you have purchased. Their installation documents have been known to be 'out of date' by a year or two (meanwhile they have changed wood suppliers 3 times in that 12 month time frame).

If you have not purchased the flooring I would highly recommend looking elsewhere for floors. LL has a long history of selling poor quality products.

@ SJ McCarthy Could you elaborate on Bella Cera being a 'private label' created by LL? I was seriously considering buying Bella Cera engineered wood flooring and now am very unsure. After seeing your post, I could not find anything about them having a connection to LL. I do know the Bella Cera/California Classics are made in Cambodia and branded differently depending on region. Is the parent company LL or did they have a connection in the past but don't now? Would you steer clear of them as a whole because of a connection to LL?

My alternate at the moment is Kentwood. They are made in China and I can't find much about their manufacturing processes, so am leary there.

Man, do I need and want my search for engineered wood flooring to be done! I thought figuring out where each light switch went was the hardest part of the build so far, but that is quickly being replaced by choosing the wood floor that has the right color, width, quality of construction, veneer layer depth, manufacturing location, environmental considerations, VOC considerations, not to mention price point.... Sigh.

Your posts are extremely helpful, so thank you for all your posting. I had been planning on Bella Cera/Calif Classics based on what many have attested to here on Houzz. If you can provide information that reassures me I wouldn't be entering the LL blackhole, I'd still consider them. If not, any info on Kentwood is appreciated. If you were buying engineered wood flooring for your home, is there a brand that would be your go-to?

Sorry...my bad. I was thinking of Bella wood. My apologies for that.

Imagine the living conditions in Cambodia. Imagine the living conditions in China. Now image the supply chain for both. Any time you support the low-grade Asian trade you support their 'bad behaviour'.

What is your price point? What were you hoping for?
