Looking to improve your RV’s insulation this winter? It’s one of the best ways to make your RV more comfortable and save money in the long run

Here are a few ways to level up your RV. 

RV Insulation Tip #1: Fix the Windows

For most people, the best thing you can do is insulate your RV windows. The windows typically installed in campers are thin and drafty. They make the cold air leak out during the summer and hot air leak out in the winter time. 

If you have the budget, the best thing you can do is fully replace the windows. Unfortunately, it is pretty costly to do so and may take a little time if you are on the road.

One alternative if you are in a bind is to put a plastic insulating film on the window. It is not the most aesthetically pleasing solution, but in an emergency it can definitely act as a great insulator. You can also put bubble wrap on the window. The trapped air inside the bubbles helps keep the warm air and cold air from leaking through.

RV Insulation Tip #2: Cover Your Vents

As you probably already know, your vent is an important part of the RV. It helps prevent the inside of your RV from collecting mold or mildew by letting air travel in and out of the vehicle. The problem is when you’re ready for bed, you don’t want it getting too drafty in there!

This is where a vent cover can help! These are pretty inexpensive and do a great job of keeping the cold air out. 

RV Tip #3: Insulate the Doors

Is the door of your RV insulated well? One way to check is to just hold your hand close to it while it’s closed. If you feel a cold draft, it could use some improvement. 

The best thing you can do is add (or replace) the weatherstripping. This tends to get worn out over time and doesn’t work as well. It’s also pretty inexpensive and does not require a huge time investment to fix.

Once that’s done, see if you need to add caulk anywhere around the door. Weatherstripping goes a long way, but there may still be some holes where cold air is coming through. Go ahead and caulk these areas to help keep your RV warm and cozy.

Tip #4: Re-Insulate the Walls

This is the most expensive and time intensive thing you can do. That said, it will also make the largest difference. If your RV’s walls are very thin and letting cold air in, fixing the doors or windows isn’t going to do much.  


Just like insulating a home, there are a few options available. You can use spray insulation - either  fiberglass insulation or a rigid foam. 

It’s best if a professional does this for you. Working on an RV is a bit different than replacing insulation on a house, and you don’t want to mess anything up.
