Does the keel ceiling ceiling have to be plywood base?

The keel ceiling does not need to be made of plywood base.

Reason: The combination of the plywood base layer and the gypsum board increases the load on the hanger. Even if gypsum board is no longer added, plywood is not well combined with putty, white, latex paint, etc.

Knowledge development: keel ceiling steps.

Elastic line (elastic line includes: elevation line, ceiling modeling position line, hanging point layout line, large and medium-sized lamp position line. ）

Boom mounting. Install the main keel.

Install the secondary keel and the cross brace keel.

Install inorganic high-strength acoustic panels.

Connect the plate to the keel with self-tapping screws.

Install the cover panel to patch the seams.

It's generally not necessary, and there is no norm for it! What's more, the combination of plywood base and gypsum board increases the load of the hanging parts! Even if you don't add gypsum board, the combination of plywood and putty, white, latex paint, etc. will not be good!

Totally unnecessary! Not on the norm! What's more, the combination of plywood base and gypsum board increases the load of the hanging parts! Even if you don't add gypsum board, the combination of plywood and putty, white, latex paint, etc. will not be good!

There's no need for that, the iron keel, the wooden keel, can be done directly.
