Glazed patio, pressure-treated deck?

[Viqtory]

Hello,

Need to replace moisture-damaged pressure-treated decking on our enclosed porch due to odor. Is it madness to lay new pressure-treated decking after addressing the moisture issues?

The alternative is Siberian larch but I don't quite have the money for that right now. And it seems to be very common with pressure-treated decking in sunrooms? Is it really that dangerous?

Several people around me have built conservatories on existing patios. Some just have the decking exposed, while others have put down something like balcony carpet.
