attic floor

First is this attic floor even built for storage?
What's the width of the floor joist, spans and spacing?
What type and thickness of OSB did you use?
Was it T & G?

I have 11/32 osb .the studs are 18" apart 2 by 8 i believe but need to measure.

Is linoleum the lightest of all flooring? is the rubber heavier?(reguarless of my project)

Does a pound of feathers weigh the same as a pound of lead?

The minimum thickness subflooring should have been 3/4, it needed to be Tounged and groved to reduce flexing, there also should have been constrution adhesive on top of the joist (studs are what a wall, not a floor is built with)
It should have been nailed with ring shanked nails every 6 to 8".

What's the spans on the joist? (the distance from one support to the next)

What differance does it make what the weight of the linolium is?

Good idea, yes, you need to remeasure. I doubt the on center spacing is 18". And 11/32" OSB? You don't want to be walking on that much. Min. subfloor is 5/8" ply or 3/4" OSB. Joe asked about the joists' span earlier. You didn't answer.

OSB will act as a vapor retarder. Most floor coverings will also help stop the moisture from getting to the roof sheathing where the passive air-flow will get rid of it before it damages your wood framing. As "it gets hot up there" you need more insulation/ventilation, not storage...
