In this blog post, we will answer the following question: How do you insulate a teardrop trailer? We will discuss what are the best types of insulation materials for a teardrop trailer and how to apply them. We will also discuss the benefits of having an insulated teardrop trailer.
How do you insulate a teardrop trailer?
Insulating a teardrop trailer must be done immediately after you’re done installing the floor and the walls of this tiny camper. Because of its dimensions, it can be quite difficult to insulate a teardrop trailer aftermarket, but it’s not impossible to do.
Here are the basics of insulating a teardrop trailer:
- Cut insulation sections with a utility knife to fit along the sides of the trailer between the beams. Insulation can also be added to the ceiling and floor of your trailer.
- Cut in the back of the insulation with 1/2 inch spacers when mounting the insulation in the curved areas within your teardrop trailer. Don’t cut all the way through so you can bend the insulation.
- Secure the insulation with 2-inch aluminum tape. Secure edges of the insulation with the tape along the beams.
- Seal and caulk rivets and roof seams to prevent rain leaks. Another option is to install a one-piece, seamless fibreglass reinforced steel roof. This type of roof is bolted to the sidewalls of the interior of the teardrop trailer.
What insulating materials to use for a teardrop trailer?
To insulate the teardrop trailer, there are different materials with different prices, which you should choose according to your budget. Next, we are going to present to you the three best materials to insulate your teardrop trailer and we will also give you some tips for their installation.
- Self-adhesive thermal insulation: Although it is not the cheapest, one of the best materials to insulate your trailer is Armaflex or Kaiflex, a self-adhesive thermal insulation, with which the interior of the vehicle will be unified since its flexibility allows it to adapt well to all types of reliefs that exist inside the trailer.
You will simply have to measure the interior of your teardrop trailer well and buy the amount you need. The price of this material is around 11$ per square foot.
Among the advantages of this insulating material are its great ability to isolate noise, especially the vibrations of the sheet, and it’s easy installation. To insulate the teardrop trailer with this material, you will only have to measure the different areas of the trailer where you want to place it and cut it with a utility knife.
Once you have the exact cutout, you will simply have to stick it on the walls, ceiling and floor of the interior of your trailer with the adhesive.
- Rock wool panel: If your budget is lower and buying Armaflex or Kaiflex is out of price, you can opt for rock wool. It is a good material for insulation against heat, fire and noise, which adapts easily to the relief of the trailer. In addition, another positive part of stone wool is its price, which is around 4 $ per panel.
However, rock wool has harmful substances (not carcinogenic) so it is advisable to use a mask, gloves, glasses and disposable clothing during its installation. In addition, it is not a waterproof material, so it can absorb water, retain it, and lose its insulating capacity. For this reason, it is also important to bear in mind that this material should never be in contact with the sheet metal of the trailer
- Extruded polystyrene: The last of the best materials to insulate the teardrop trailer is extruded polystyrene, which has good thermal insulation, although it is more difficult to adapt to the reliefs of the trailer than the previous materials mentioned.
The advantages of extruded polystyrene over rock wool panels are that it does not absorb water and that it does not release substances harmful to health. Extruded polystyrene is priced at around 5 $ per square foot, making it an intermediate option in terms of budget for insulating a teardrop trailer.
Now that you know the different options to insulate your teardrop trailer you just have to get down to work. Of course, remember that the best option is self-adhesive thermal insulation, although it is also the most expensive. Once the trailer is insulated, you can equip it with everything you need to go on a trip with it.

Insulate windows and doors of the teardrop camper
The windows and doors of teardrop trailers can let in a lot of hot air if they are not properly sealed. Doors and windows of older campers can be particularly exposed to drafts if you have never replaced or repaired the weatherstripping or caulking. Here are some solutions to improve the insulation of the doors and windows of your teardrop trailer in summer:
- Add New Caulk: The caulk around the doors and windows of your trailer can crack or chip over time, allowing outside air to enter your trailer. By closing the windows of your teardrop trailer with a new coat of sealant, you can block out hot air. It is advisable to re-caulk the windows every two years or as soon as you notice a draft in your trailer.
- Replace the weatherstripping: The weatherstripping on your teardrop trailer can also wear out over time and lose its insulating properties. Inspect your trailer weatherstripping for holes, cracks, or gaps. Replace any damaged weather stripping.
- Add reflective insulation: Reflective insulation helps cool your teardrop trailer by blocking the sun’s rays. Place sheets of reflective insulation in the windows of your teardrop trailer and secure them with duct tape.
- Use a Door Snake: A proven method of draft protection, a door snake is simply a fabric or foam tube that sits on the bottom of your door to prevent drafts. You can easily make your own door snake using a piece of fabric filled with rice, beans, or dried lentils.

- Measure and cut your cleats according to your plan made on the ground
- Glue your cleats to the ground according to the plan, then add two screws if necessary on each end of the cleats (about 3cm from each end)
