Reflective tarps help turn the sun’s warm rays away from your little pop up and help keep you cooler on those hot nights that usually keep everyone from sleeping comfortably. Once in place you should find your pop up a better place to be.

There are two options of these reflective tarps available for your summer use. The interior liner slides between your camper’s frame and its mesh walls. The other option is called the bunk end covers and they are held into place by the included bungee cords and clamps.

What you have to watch out for is that there are different styles of these reflective tarps and each style has a different wind resistance rating. Those ratings go from 10 mph to over 25 mph. Just pick the one that is suitable for the wind in the area you are camping.

Then, if you do not want to buy these reflective tarps, you can always make your own. There are ways to combine thermal blankets with regular tarps and the internet is full of instructions on how to do that.

3. Make Use Of Black Out Curtains

You have probably seen these in different homes you have visited. They work well for those people on the graveyard shift when they have to sleep through the day. These curtains can come with a rubber backing that helps provide extra insulation when you need it.

In addition to that feature, blackout curtains are made from thicker material that not blocks the sun’s rays. They keep the light away and can also keep cooler temperatures at bay as well.

The good news is that these curtains come in different sizes, types and colors. You can keep your pop camper looking good while protecting yourself from the outside elements.

What makes them a good insulation choice is that these blackout curtains are easy to adjust. You can slide them out of the way when you want the light inside your pop up camper. Then slide them back into place when you want to cool it down.

4. Effectively Stop The Leaks

When that happens,little cracks and holes develop which let the outside air inside your pop up camper. To insulate, all you have to do is take a little time and search your camper for every little spot that has come loose and made a gap in its structure.
