Great Ways To Insulate A Tent For Your Cold Weather Camping Trips

Last Updated on

Most people are well aware of how to keep themselves warm while camping but not so much how they can insulate their tent in order to reduce clothing bulk.

If you’ve never done it before, here are a few insulation tips to keep the cold outside and the warmth in.

How Does Tent Insulation Work?

The basic principles of tent insulation are straightforward.

It’s cold outside. You don’t want it to be cold inside. The trick is that heat likes to escape, and you’re in a tent, not a house with solid walls and insulation.

This means that you have to create a barrier to reduce the heat transfer from one material to another. Basically, you have to trap body heat or heat from a tent heater inside your tent.

That might sound like a tall order, but keep in mind that your tent isn’t a house. Houses are big and spacious and have multiple rooms and areas to insulate. A tent is a fraction of the size and only requires two areas of insulation: the walls and the ground.

In addition, you don’t necessarily need to heat the entire space inside your tent. You just have to keep yourself warm. Trapped body heat is more than enough to do the job, provided that you take the right approach.

Tips to Insulate a Tent

With that in mind, let’s talk about how to insulate a tent.

The biggest thing to keep in mind here is efficiency. You want to maximize heat conservation and minimize heat waste. That means reducing how much heat can escape and eliminating factors that would lead to runaway heat.

Bring a Small Tent

The best place to start is actually quite simple: bring a smaller tent. In fact, bring your smallest tent.

The reason is simple. Smaller is warmer. The less space you have to heat, the more the heat you have stays close to you. Ergo, warmer tent.

So, that big, breezy tent you use in the summertime? It’s going to be a popsicle in the winter.

If you want more space, it is possible to get larger tents that are engineered for winter camping, but you’re going to have a harder time heating them solely because you have more space to account for.

Location, Location, Location

Got your tent? Great! Now let’s talk about where to put the tent.

Location is essential in any kind of camping, but for winter camping, it’s absolutely critical. Remember, your primary goal is to reduce heat transfer. Where you put your tent dramatically affects your success in heating it.

Exposure is a major factor here. Those beautiful clearings you love to camp in during the summertime? They’ll leave you exposed to the wind during the winter. Make friends with the tree — they do a lot of work to protect you from wind and snow.

By the way, wind can change direction. Don’t rely on one wall of trees — look for a spot that’s protected on all sides.

In addition, watch out for any depressions or low ground when pitching your tent. Snow flows down, so if your tent is pitched in a depression, you’re likely to get flooded.

Also, think about where you’re going to make your fire. It’s one of the most reliable sources of heat, so if you can boost heat near your tent, you have more wiggle room for heat loss. We’re not saying pitch your tent directly on top of your fire — keep a minimum safe distance of two meters (about 6.5 feet).

Create a Windbreak

Now that you’ve covered basic wind protection, it’s time to deal with incidental wind. This is where a windbreak is a lifesaver.

If you can, try to find a campsite with a rock shelter. Even a thick clump of trees can help provide a natural windbreak.

However, if it’s not possible to go au naturel (and even if you do have a rock shelter), hang a line between to stakes or trees, hang a tarp on the line, and secure the bottom to stakes.

Materials for Insulating the Walls and Roof

Once you’ve gotten protection around the tent, turn your attention to the tent itself.

Generally, there are two important qualities in heat transfer:

  1. Density
  2. Reflectivity

Since the flow of heat in solids happens when atoms collide with each other (thus increasing their internal energy) materials with a higher molecular density (i.e. more molecules closer together) have more frequent collisions and thus greater thermal conductivity.

In plain English: the denser the material, the more it conducts heat and thus the faster it loses heat.

This is why the best insulation materials on the market get rid of most solid material and instead trap as much air inside as possible, usually in air pockets.

Reflectivity refers to the fraction of radiation arriving at a surface which is reflected back. If radiation is reflected back, it’s not absorbed into the material. In the case of heat, this means more heat is bounced back at you instead of escaping into the material.

Insulated Foam Rolls

With both of these factors in mind, the best insulation material for your tent walls is heavy-duty reflective foam, which relies on pockets human-safe trapped gases (less dense than air) and a reflective surface to minimize heat transfer. This material is flexible enough to be duct-taped to the tent walls, roof, and floor.

This will take a bit more time (and a healthy supply of duct tape) but it’s effective.

Use Ground Insulation

We’ve talked a lot about walls. Now it’s time to look down.

Once you lie down in the tent, you definitely want to feel comfortable. The problem is that the ground is excellent at retaining cold, and the last thing you want is the winter chill seeping slowly into your bones while you sleep.

A ground rug, a mat, a blanket, even some spare towels can help mitigate heat loss while you sleep.

It’s also a good idea to add a layer of reflective foam on top of your ground cover, with aluminum on both sides, as this will reflect heat back inside the tent instead of allowing it to escape into the ground.

In terms of your sleeping solution an air bed rather than a camping cot can work very well in this situation. An air bed traps the air beneath you and doesn’t allow airflow. A cot however will allow cooler air to flow beneath.

The Ready Made Solution

If you don’t fancy adding insulation roll and duck tape to the inside of your tent there is an easier option. It’s also a pricier one.

Let us introduce the Crua Cocoon insulated tent. This is actually an inflatable tent inner using air and a patented material to regulate the temperature inside the tent in both hot and cold scenarios. It’s also great at dampening sound from a busy campground and for blocking out the light for a longer lie in.

The Crua Cocoon works best when used inside a larger standard tent or with Crua’s own Duo Maxx Tent. Alternatively you could setup a tarp to protect from the rain or snow. The reviews on Amazon speak for themselves though, if you can afford it. Bear in mind it doesn’t come with the pump either!
