Doors can also be a source of air leaks, so proper insulation is vital. Apply weatherstripping and caulk to improve the insulation of your pop-up camper doors without compromising their functionality. Make sure any gaps or openings are sealed to prevent drafts.

Dealing with Air Leaks and Openings

Address any additional air leaks and openings. Examine canvas walls and bunk-end covers for any damage and repair if needed. Seal any cracks or gaps and ensure you have a tight and well-insulated space for your camping adventure.

Choosing the Right Insulation Material

When it comes to insulating your pop-up camper, picking the right material is essential. Let’s explore some popular options to keep you warm and cozy on your camping adventures.

Bubble Wrap

Bubble wrap might not seem like the most obvious choice, but it can be an effective and inexpensive insulation material for your pop-up camper. Simply cut it to size and tape it to the inside of your camper’s windows, walls, or ceiling. Not only does it offer a decent level of insulation, but it’s also lightweight and easy to remove when you’re not camping in colder climates.

Reflectix Insulation

Reflectix insulation is a type of reflective insulation that bounces radiant heat back towards its source, making it ideal for both hot and cold climates. To install this in your pop-up camper, just cut it to size and attach it to the walls, ceiling, or floor with double-sided tape or adhesive. Reflectix has the added bonus of being water-resistant and can help reduce noise levels in your camper.

Foam Board Insulation

Foam board insulation is a popular choice for pop-up campers because it offers excellent thermal resistance and is easy to cut and shape. When using foam insulation boards, you’ll want to measure and cut them to fit the interior walls, ceiling, and floor of your camper, securing them with adhesive or screws. There are several options available, including expanded polystyrene (EPS), extruded polystyrene (XPS), and polyisocyanurate foam boards, each with varying insulating properties and price points.


Fiberglass insulation is another option that can be used in your pop-up camper. It’s lightweight, easy to work with, and provides excellent insulation. However, working with fiberglass can be a bit more challenging, as it’s essential to wear protective gear to avoid irritation. To install fiberglass, cut it to fit your camper’s walls, floor, or ceiling, and secure it using adhesive or fasteners.
