Hey all,
thanks to everyone who replied about the insulations.  seems the silver
bubble wrap is very popular.  I checked both home depot and lowes, niether
stock it.  where can I find this stuff.  Also,
what if I used regular bubble wrap and used foil emergency camping blanket
as my vapor barrier.  Would this carry any advantage???
thanks
