We have a pretty big, unconditioned attic that is all wasted space. The only thing up there is a furnace/air conditioner, which sits on a small platform accessible from the attic access panel.The rest of the attic is simply ceiling joists, and loose insulation and insulated HVAC ducting.Would it be a horrible idea to lay down some 3/4” subfloor-grade plywood, so at least the space could be somewhat usable for non-sensitive storage?The attic space isn’t sealed, nor are the ceiling joists of the roof insulated/sheeted. I’d be laying the plywood directly on top of the insulation and joists. We would use it primarily for seasonal decoration storage or something.Is this a bad idea? Is 3/4” subfloor overkill ($25/sheet) Could I use 1/2” osb or other cheaper plywood?I’ve got little to no interest in finishing the space, I just would like to be able to walk around up there and move some stuff out of basement storage.Thanks! via /r/DIY https://ift.tt/2NAovkJ
