White or Pink Foam?

[GreenDiesel]

Rob:  I never think of the foam with tinfoil on it.  That cut end will shed beads when people rub against it.

I made one of our layouts with a tray of upside-down L-girders covering the edges of the foam.

There shouldn't be heat concerns in the wiring if you run the layout moderately.  I have heard cautions about chemical reactions between the foam and wire insulation but never seen any.

Thanks, David. 

I've 'sealed' the foam on the other side with a thin layer of white glue. That should solve the problem above. Also, I plan to insert the foam into a wooden frame that I made so no one will come in contact with the foam as it's surrounded by the wooden frame. Even still, I could also seal this end as well with the white glue. 

So it should be fine based on this?

Great that there should not be any heat issues.
