Particle board walls in garage

We recently moved into a house and today we discovered that the garage walls are made of particle board. Not OSB, not plywood, but actual particleboard. There are sheets of plywood at each corner on either side of the corner, and the other sheets are particleboard. The exterior sheathing is aluminum siding. It has been very rainy lately, and the particleboard has darkened noticeably with moisture, although there are no leaks. . How long can we expect these walls to last, and what would the project look like to replace them?

Particle board absorbs moisture out if the air, so its not a good product to use outside. If the outside is actually getting wet... as in they never used any housewrap behind the siding, that would shorten it's life considerably. So it's hard to say exactly. It really depends on if it stays dry or not. You might be able to extend it's life by painting one side of it. But to replace it, all the siding obviously has to come off.
