That and Depron is really hard to get in the US, while every where else seems to think so little of it they use it to line their walls
the DTFB (Adams ready-board) core is very similar, though thinner, but the paper adds quite a bit of rigidity. lining it with thin vinyl sheeting or packing tape will help tremendously.
Hi Guys,
I was wondering if any of you have built using Depron foam? How easy is it to follow plans for an FT model with Depron, etc? Do you have to tape the edges for example? BTW this would be 6mm foam.
All the best,
cooie
Thanks very much for your replies!
Craftydan,
Depron is really not that hard to get in the US, it's just very expensive when compared to DTF
Coolie,
This just got posted. The Spitfire in post #210 was done with Depron.

Ah, that spit looks great! I wonder if he/she will do a build vid!
I was just reading about depron. Apparently it's brittle. So if your a 'crashy' kind of person, I'd avoid. As for people who say the paper on foam board adds weight, so does packing tape that people seem to cover depron.
most of it weighs less, at least the colored stuff does...
Sorry, the stuff I use is only 2mil so it's lighter than the "normal" packing tapes. It's not available at the local store though. The type of tape used will have a dramatic effect on weight depending on what kind of tape you have available. Consider the weight differences between Duct tape(heavy), Heavy duty packing tape(medium), and the super thin colored packing tape(lightest). There is a huge range of not only weights but thicknesses, as well. You just have to choose what will work best for your needs.In my experience, the vast majority of packing tapes on the shelves at the local Big Box Stores do indeed weigh more than the paper on DT foam. The thinnest tape I have found is Duck HD Clear which does indeed weigh almost exactly that of the paper on DT foam. This tape has a 2.6 mil thickness, and I believe the colored tapes are 2.1 mil, so those should be a little lighter.
For reference, a sheet of DT foam board weighs about 120 grams; 60 grams for the foam and 30 grams for each sheet of paper.
I did actually weigh a roll of Duck HD Clear full and empty, and a 1.88" x 54 yard roll contains 182 grams of tape. When you do the math, this comes out to almost exactly 30 grams to cover a 20" x 30" area with no overlap.
