Hello, I plan to add flooring for seasonal storage to my attic(house was built in 51).
How should I determine if the joists need to be reinforced to accommodate flooring?
I plan on using 5/8 OSB. Is that sufficient?
Also, there's blown insulation that's flush with the joist. Will I cause problems going right over it, or should I make a space between the floor and the joist by furring it up?
Any help would be appreciated.
