I need to install flooring in my attic so I can store miscellaneous items there. Ive been told that sheeting the whole thing with plywood or particleboard is not a good idea because you trap the insulation and it cant do its job. The other suggestions that I have been given are:
1. Use 1x 4 boards spaced 2 apart. (Simple)
2. Use Ύ x 2 x 8 or 1 x 8 sections of plywood or particleboard spaced 2 apart. (Quick)
3. Use Ύ plywood or particleboard with a lot of 2 holes drilled in it. (Seems like a lot of work.)
Are any of these ideas OK to use? Do you have any other ideas that may be better?
