Install grooved ecoply in vaulted ceiling

We have a high vaulted ceiling with exposed beams but painted chipboard. Want to cover the chipboard with grooved ecoply for a faux tongue and groove look. Or something similar, open to ideas. It's approx 50sqm with each section between beams approx 1m x 3m and there are 18 sections (4 are closer to 60cm x 3m).
