Two words for you
Bubble
Wrap
It truly works. I bought 2 rolls of it for a 10X12 greenhouse. Just make sure you get the continuous vs the perforated rolls. First, I put clear plastic sheeting on the walls and across the ceiling where the walls and roof line meet. If you lower your ceiling then you aren't losing heat at the peak. Then I put bubble wrap up on the walls and across the top.
Handy tech tip: I pulled the shadecloth off the top at the end of October because the sun isn't so bright. Adding plastic and bubble wrap will cut the sunlight. If you have a shade house, no problem. If you grow higher light, then you may want to add light fixtures. But seriously, if your going to save money on propane, you can swing some lights.
I use a 1500 watt electric heater and can maintain 55 degrees when the temps are below 30. When the temps are mild, I open the doors and pull fresh air in with a fan.
I have some pictures somewhere. I'll have to dig them up and post
