Question:

Can I install old, hollow core, interior doors as attic flooring?

I just replaced all of the interior doors in my house (14) with 6-panel doorsThe flooring in my attic is 30 year old, 3/8 plywoodWhat I want to do is use those old doors to replace the plywood flooring in the atticStructurally, there's nothing wrong with them and they'd seem to make a better thermal insulator than the plywood.My concern is if they'll sag between the trusses over time with weight over themThey won't be loaded down or anything, just the usual attic stuffI'm tired of bouncing around up there as the current flooring moves like crazy when I walk on itI have all of these doors, so I figured I'd give it a shotThey seem to be a little stronger than the newer ones (as does everything it seems).Anyone have any thoughts?

Answer:

No, for forming cases you need a good strong O frame pressA C frame press will spring out of shape during the reforming processWhy not just buy unfired .308 Norma brass and load it?
Most hollow core doors are made of 1/8 thick Luan overlaid on 11/2 thick frameI wouldn`t recommend them for attic flooring, as they will not support any weight, especially if anyone is walking/crawling around up thereIf they were to step on the Luan only, they most likely would fall throughAs to the insulating value, yes, anything that traps air space increases insulation valueIf you were to cross your rafters with them, and then OVERLAY them with plywood/planking, it would be OK, otherwise, I wouldn`t do it if there is a risk of getting someone hurtAlso consider, is there any electrical wiring, vents, ductwork, etc, you would be covering?
