How soon can I move in after installation with ENF-grade boards?

ENF is only the environmental grade of the boards themselves; you can move in right after installation. For edge banding, we can use PUR edge banding or laser edge banding, which reduces odor release. Board options include HENF, ENF, E0, etc.; ENF is one of the stricter tiers. Don't look only at the board grade—passing testing after installation is the real standard.
