How much is the wall of punched plywood one square metre?
The second is not economic, poor plywood, batch of putty will soon be degumming, peeling, high quality plywood prices more expensive than gypsum board, but not as good as gypsum board partition effect. Third, plywood is generally good, there are formaldehyde, not green. I hope my answer will be of some help to you.
Light steel keel frame, plywood surface, single-sided 85 yuan / square, double-sided 115 yuan / square meter. Plywood is not suitable for partitions. One is the fear of water, water absorption will become uneven.
