Tricky headline, but I don't know what the boards are called.
They are usually about 5 cm thick, made of long wood shavings glued together loosely, often found in ceilings of older factory buildings, etc., as acoustic panels.
Anyway, my basement walls in the house from 1958 are insulated with such boards, which are then plastered. The previous owner had problems with moisture, including in a room that someone had previously decorated, they redrained the house and removed the interior, so the problem no longer exists, but the plaster hasn't been addressed in a corner. Out of curiosity, I dug a little into the plaster to see how it looked behind, the board should reasonably have been damaged by the moisture, even if it is dry now, but I can't see any change whatsoever, I dug a bit with a knife, but the shavings are hard.
So the question is: Are they impregnated with something, and what is used as the binder/glue?

So simple and so smart, why isn't this material used more?
