If I recall corectly, RNC is CPVC. Which is lower smoke emmision than PVC.

No need to be sorry. I learned something new, so the day wasn't a complete loss.

Have used PVC conduit in sweveral different type of plants all of which have somewhat nasty enviromental work areas. If the are large temp changes even a lot of expansion joints will not keep the install from looking bad in a couple of years. But it's a lot easier and much much cheaper than Robroy. If a customer needs robroy or other PVC coated rigid, prepare them for severe sticker shock. Also get a good count of couplings, connectors, and other hard ware. It's all expensive and an extra cost. You will need special tools to install, cut and thread it also
I also hate that stuff

That is very true, be ready to provide CPR when you give the customer the price.

One of our guys did a job in a hazardous location with PVC coated RMC.

What a pain in the rear!

Short an LB or a junction box, the job stops for days to weeks to get the expensive parts out to the job, not shelf items at any supply houses we deal with.

Even PVC coated 1 hole clips with stand offs had lead time and a high price.

I installed a 480 volt 30 amp 3 phase PVC coated hazardous location receptacle and matching cord cap, they told me just that was over $2,000.

The receptacle had a switch in it that killed a contactor outside the hazardous area when you started to remove the cord cap.

I like EMT and MC.

Don't most non-wool carpets give off the same fumes?

I hope not.

Almost all of the furnishings used in a house give off fumes that are every bit as toxic as the nonmetallic conduit fumes. In my opinion, in most types of buildings, the toxic fumes given off by burning building materials are so much less than those given off by the burning contents and furnishings in the structure that the fumes from nonmetallic conduit or plumbing piping are almost insignificant. By the way, wool produces cyanide gas when it burns.
