Looks like an excellent product, Steve.
Haven't seen anything like that in our stores here.

You could also visit a shop that sells plexiglass and see if they have any cut pieces (free or cheap)
A 3-foot by 2-foot "window" in a palm hut south wall would work too.

I was thinking that as well. Just want to use some sun to help out during the day.

Thanks! Will be using supplemental heat as well on those extremely cold nights either c-9 bulbs on thermocube or i may just use small ceramic heater with thermucube.

I really love stuff like that,you can use it on a east/southeast wall of your
protection but for sure get a remote sensor in there because clear panels can
really jack the temps,I had an umbrella g-house over my Washy and at the
end of winter the temps would easily exceed 120F with it opened up.

Wal-Mart here sells clear pvc plastic by the yard so I use that over the cactus as long as possible.

And Washies love that, no wonder yours do so well, Jim.
That temp would fry a Trachy.

Perfect!
Just double check which T-cube you're purchasing.

TC-1 - On at 0 F, Off approx. 10 F
TC-2 - On at 20 F, Off approx. 30 F
TC-3 - On at 35 F, Off approx. 45 F
TC-21 - On at 78 F, Off approx. 70 F
TC-22 - On at 120 F, Off approx. 100 F 😆

I use T-3.

Don`t forget to use lots of mulch on the ground around the trunk.

Also having a way to vent structure on "hot" days. and mulching ground well
