Re: Attic Storage - What to Put Up There
I don't see a problem with storing papers & such in the attic. However, I don't recommend storing CDs, records, or tape recordings; the heat can warp the plastic and change the properties of writable CDs. Also, don't store volatile compounds up there, such as spray paint, adhesives, or those extra propane cans for your campstove. It just gets too hot up there, and freezing isn't good for paint.
It's good that you installed a subfloor; the ceiling attached to the bottom side of the joists isn't suitable for any more weight than the insulation. Stepping on the ceiling between the joists will very likely lead to serious injury!

I have read several books on various home improvement topics. I do not have any current code books I can refer to. I was an apprentice plumber for two years.
