Pop-up roof thickness and material?

Howdy...
I have acquired a very nice original Westfalia pop-up roof internal insulation set (as seen here, although I found mine second hand for much less!): https://www.serial-kombi.com/en-GB/transporter-t4-california-/-elevating-roof-skylight-n311590
Now, mine arrived without installation instructions, so just a catch up before i start drilling and screwing into the roof for the 'tenax' fasteners (that have a 12mm screw length), does anyone have any info on the build of the pop-top roof - I think i read that it has a plywood core?
I'm sure as this is a genuine Westfalia product, that its completely safe to go ahead and place these screws, but being safe than sorry just looking for some info on the roof.

Cheers

I believe that the roof has foam in the middle, saw a few forum posts about fitting roofbars, and saw a green foam from the drilling.
Can it be fitted by using the screws that hold the canvas on?
I went for a Brandrup internal insulation, it is just held on with Velcro and a few pop fasteners screwed in to the rails that hold the canvas in place.

I took the plunge and cautiously drilled the first hole...
Had a shock when after only a few millimetres the drilled plunged through!
Quickly ran out to check... but yes seems there is a foam core, so no holes through to the outside ;-)
So it's up and very happy with it. We're giving it's first trail tonight and the difference is very noticeable, warmer and indeed quieter...
Very happy with my find!
