Like a single pane of glass, bubble-type reflective covers probably have only an R-1 insulation value.

If you like a lot of light, bigger windows are a great idea-until winter hits. Most RV windows have a single pane-not the best at keeping out the cold. All will take some degree of work to make or install, but several aren’t particularly hard. Some RV window solutions are more expensive, but most are downright cheap.

Try this: Buy canned smoke or light a match and blow it out, then hold it near a closed RV window, making sure not to get too near curtains. One problem with RV windows is that build quality isn’t the greatest on many RVs, and the stress from frequent travel just make that worse.
