Thanks I did the walls of the pinball room when I put the extension in and on a hot day you cam really tell the difference but the roof really heats up.I suppose Im more worried about the condensation and the effects on the pins.I keep them covered.Im in Portland Vic so we do get some shitty weather.
It will probably have to be some sort of silsalation stuck to the ceiling with silicon or such.
Cheers
