Cellular shades

I ran across this study recently and I have noticed a real difference in heat and cold:

A 2022 analysis from Oak Ridge National Laboratory (ORNL) found even more promising results. In winter, cellular shades can save up to 20 percent on heating costs, compared with blinds, per that assessment. In summer, ORNL researchers determined cooling savings were also up to 15 percent. Mahabir Bhandari, a co-author on that study and an efficiency and buildings researcher at ORNL, agrees that cellular shades are one of the most affordable and accessible options for boosting home energy efficiency. “You can go to Home Depot or Lowe’s and easily get whatever kind you want,” he says. Most are easily self-installed. The least expensive versions start around $25.

After being on Florida for the last 3 weeks, it's apparent our blinds are not sufficient for keeping the heat out.

I'm going to install ceramic ir film on the windows. Quality film is difficult to source.

Tint depot has it but its currently out of stock.

Eric, you need to come by and check my selection of blinds. I have a bunch of cellular. Will make you a deal. 
Thought I bought 49 blinds 2 years ago. Turned out to be 49 skids of all types. Sorted and organized them. Sold bunches of 2 inch faux wood. Gave 3 skids of 1 inch to habitat for humanity. Filled bus up with roll up style and took to old mining town in wyoming that we helped rehab. Been meaning to list on here to see if anyone was interested. The cellular are perfect for campers and buses

I might need to stop by some time.
We put the electric ones in the living room of the house where we watch TV and it's amazing how convenient they are. Kinda expensive but the wife just loves running them all up or down with one button press, since they can link together wirelessly. I'd think in a bus those would be just the best.
