I’m trying to finish an attic, however, can lights from the living room and other electrical peeks above the joist about an inch give or take. How would I finish the floor with those obstructions in the way. By the way the joist are 16 inches on center.

Thanks in advance,

    How large are your attic joists? Sometimes the joists are sized to be an attic, not a finished space. – kponz Dec 10 '18 at 14:37

    The clearance needed would depend on the type of can light. Some need 3" above to allow the heat to dissipate. – Ed Beal Dec 10 '18 at 16:10
  • Thx for the answers, the joist I think are 2x6, and I’m just guessing. So in this case if it’s not sufficient enough for a floor what do I need to do, and what if subfloor is placed over existing, what would or could happen. – Tajuan Riley Dec 10 '18 at 21:37
  • How far do the 2x6s span? @TajuanRiley – kponz Dec 11 '18 at 0:07
  • 16 inch’s is what they span – Tajuan Riley Dec 11 '18 at 1:25

Assuming your joists are adequately sized to support the space you're finishing, you could add 2x2's (or 2x4's laid flat - they're likely less expensive) run perpendicular to the joists. This would raise the floor around 1.5", enough to clear the obstructions.

Glue and screw each layer to prevent squeaking.

  • Do I lay the 2x4 flat 16 on center as well. I most likely will have professional help but I still need to educate my self on these topics, I had problems years ago by being ignorant to certain things regarding renovating. – Tajuan Riley Dec 10 '18 at 21:39
