Hi Tammy....I'm no expert either, so we will get along nicely! LOL
I'll still stick by my first thoughts on the browning/scorching of leaf margins, only because that's the only problem I've encountered that produced similar results. As before, I'm always careful with tender tropicals to allow them an acclimatization period of at least a week in a spot protected from direct sun, wind and even hard rain. The relative humidity varies greatly around the country, and plants will sometimes not be able to maintain lush growth at points furthest from the roots, which would include those leaf margins. I'm on Vancouver Island, which has a fairly humid climate (classed as temperate rainforest), so may be just lucky to not see those symptoms on my plants. Again, ordinarily, plants will not actively grow at temperatures around the 40 degree mark, so the root system won't be active either, and "wind scorch" could easily occur. It is rhetorical just the same, since the plants are certainly not as attractive as you'd like because of the damaged edges. The fact that you have to lug plants back and forth because of record low temperatures can't be much fun either! We're stuck with temperatures below the norm here for the last couple of months as well, and there's a lot of grumpy gardeners about as a result. I hope you find the answer to your problem soon and spring/summer temperatures bless us all! P.S. Am I safe in assuming you are in the American southeast, which has been experiencing some oddly cool temperatures lately?

I'm no expert either, but the symptoms sure look like those you'd expect to see on a plant that hasn't bee "hardened off" before being placed inside. If the plant has been inside all winter, its tissues won't be able to handle full sun, full wind, etc., as Rik mentioned. I'd put it outside in dappled shade under the canopy of a tree for a week or so before putting in a fully exposed spot. Alternately, you can put it in full sun, and the existing leaves won't be totally happy, but the new ones that emerge will be fine.

There is no need to bring anything inside for 36F. They'll be fine - all of the plants. I leave my plants out even if it's going down to 32F because one hour of 32F is not going to do any damage and it takes at least 4 hours at 32 for anything to freeze. None of my plants, regardless of what they are tropical wise, have ever suffered any damage below 42F or above 32F.

I know there are some tropicals that don't like to be below 42F but I don't have any of those.

However, if there is any kind of a breeze or it's windy and it's in the mid-30s there is a decent chance of wind burn or a major drying out of the leaves/fronds so watering before sundown will help.
