Planning my shop Build-out for next summer, looking for advice.

Installed ballistix floor coating on floor my air compressor is under stairs. The air line wraps entire shop complete 360 for maximum air pressure with several drops throughout. I went with brighter lights under mezzanine as easier to see for engine work or tedious work. And will complete a separate paint booth next year just to do everything myself (hopefully). Stainless sink area needs finished and full bathroom need completed as well.View attachment 1716310545View attachment 1716310546View attachment 1716310547
What a great layout. Can I ask what the white panels hanging from the ceiling joist are for?
