Hello. I have a house built in '58 where both the ceiling and interior walls are made of a masonite/board material. I've googled and found that it's Tretex. I'm going to install a ceiling consisting of panel boards in 10mm MDF. Since these don't weigh as much as wood panels, can I manage to attach them directly to the ceiling, or do I need to install joists first?
How were you planning to attach the MDF panel, glue or nail?
If you choose to nail, it's a big advantage to know where there is wood behind the tretex.

Take down the tretex and you'll see, you'll regret it if you build layer upon layer..Kajsa76 said:

I had the same in a house, and eagerly I placed porous boards underneath and nailed with side clips and nails that came with it. I thought they held well. Everything was fine, very pleased, but then six months later I woke up to a crash. Half the ceiling had fallen down, I investigated, the nails were too short, they had only reached the surface layer with the tip. So another round of getting it in order, I gathered everything and bought longer nails that went a bit into the surface layer. But it meant buying more boards.
