those basement systems have been around for a few years. they seem to hold up pretty well.
The issues with fiberglass is that it traps organic debrie. Like dust, pet hair , human skin particles, food kicked up when you vacumn.
The science behind it is just that basic. however to finish the coctail for mold , you need water. So these panels with a dehumidifier in the summer should work ok.
The alternative is foam walls, steel studs and cement board walls.
Nothing is perfect for basements, except painting the concrete walls every few years.Then you can see everything.
Hope that helps.
