Actually thats an interesting point.. I'm going to have to have an
opening
in
the room to pass the cables in... so I suppose its never going to be
sealed
effectively. I wouldn't want to foam fill the opening incase I need to
add more cables in the future.

Good idea Keith.. I like it.. I suppose its a case of finding some pipe
that
will melt easily enough and finding a supplier of C02..
