Most RVers are well aware of just how poorly insulated the vast majority of rigs are. Unless the weather is just perfect, it can be difficult to get the temperature right in a trailer or motorhome.

One of the things that makes this extra difficult is single-pane RV windows. That’s why we recommend doing all you can to improve RV windows insulation in your rig, especially if you plan to camp in the middle of the winter or the height of summer.

Not sure how to go about insulating your RV windows properly? In this article, we will introduce you to five great ways to do just that.

Use Reflectix

Our first suggestion is Reflectix. We love Reflectix because it comes in sheets or rolls and can be cut to fit your RV windows easily. If you cut the pieces to fit snugly, they will hold themselves in place, but it’s also possible to use Command strips to hold them.

Reflectix is excellent at providing insulation and reflecting the sun away from your RV to help keep it cool in the summer, but it does block out all light. If you need to have sunshine to be a happy camper, this solution may not be for you.

Install Window Film

If sunlight coming in the windows is a must-have, you might prefer a window film insulation solution. These shrink-film window insulation kits are sold on Amazon and at home improvement stores. The film is applied using heat and it stays in place very nicely. It also provides a decent amount of insulation. All that said, the film can be a pain to apply, so you will want to be sure to set aside plenty of time for the project.

Employ Bubble Wrap

A cheap, easy, and effective option that will allow sunlight to enter the rig involves bubble wrap. Simply cut sheets of bubble wrap to fit inside your window, spritz the window with a bit of water from a spray bottle, and stick the bubble wrap on the window.

The only things we don’t love about this method are that the water doesn’t hold up forever (meaning you will likely have to reapply the bubble wrap occasionally) and that although light does get in through the wrap, you can’t see outside through it.

Make Your Own Window Covers

You might also consider some DIY covers. Lots of people have made awesome van window covers, and there are even some no-sew DIY van window cover options out there. There is no reason these methods of making van window covers couldn’t be carried over into an RV. That said, there are other options (such as sewing your own blackout curtains) to keep things nice and insulated.

Consider Double Pane Windows

Double pane windows are a fantastic, effective, and permanent RV window insulation solution. As the name suggests, double-pane windows are made of two panes of glass that have a layer of gas in between. The extra pane and layer of gas work together to provide much better RV window insulation than the traditional single-pane windows usually found in motorhomes and trailers. They also work well to block out unwanted noises.

Unfortunately, double-pane RV windows are quite heavy and expensive. They can also be damaged if the seal between the two panes is broken. Nevertheless, we do think they can be a worthwhile investment if you plan to camp in extreme temperatures regularly.

As you can see, there are several great ways to improve your RV window insulation. Pick one of the options above and get to work so you can enjoy camping in the perfect temperature on your next trip out in the RV!
