I’m a little lost on how I should prep my wood for installation. I’m going to pick up this wood to lay down on top of my insulation

It’s untreated, am I supposed to use a wood sealant on it to protect the wood? If so, do I seal both sides? Or is this unnecessary and I can just screw the wood down? Any help is appreciated, I’m clueless
