Looking for ways to keep warm in a tent in cold air environment. We have much for you.

But before that, I have one thing to say: Never compromise on quality when you are purchasing a tent for camping trip.

Let’s get into it!

Insulation is the key to any tent. If you don’t have enough it will be difficult to heat. Building an agency wall around your tent is very important.

A regular tent wall would let the cool air in and warm air out.

We have few methods to insulate your tent against cold night air and keep your tent warm.

1. Spray Foam Insulation

If you have a big enough budget then I suggest using spray foam insulation on your walls.  For you who do not know how does it work, Spray foam is a high-density polyurethane that comes in huge canisters. You spray the material on your walls and let it dry.

You want to make sure how to keep your tent warm while using this method. Check how thick is needed for your tent size or temperature rating.

Also, how long it takes to dry.

Most foam insulation can be sprayed at a temperature as low as 4 degrees celsius. That is really good news for winter camping or snow trips. You will have your tent warm!

You can check the prices of different spray foams on amazon.

2. Old blanket Trick

If you don’t budget for spray foam, then how about this one? take an old blanket, fold it up tightly and place it over your tent poles forming a “blanket” to keep air out.

Another simple non-expensive method is to keep your old thick air mattress and put it over the inside of the tent as an extra cover at night. You can use lighter blankets on top of that if needed.

The question is how do I attach the blanket to the walls of my tent?

You can use bungee straps to attach the blanket to your tent wall. That way it is easy to take down and place back up without interfering with your setup or taking too much time.

Sleeping bag: In order to stay warm, you should use an insulated sleeping bags. Because the materials are thick and close, your body heat will be reflected, keeping you warm. Choose a sleeping bag that is advertised as cold. sleeping bag liner can add several degrees of warmth to your sleeping

3. Multi-layer System

We are going to show you how to build up a Multi-Layer wall system for keeping tents warm in winter weather below 4 degrees.

This is the method I came up with for my personal tent, and it worked!

I am using a 1- man tent but this can be used on any size or shape of the tent. You just need to cut things accordingly depending on the shape and size of the tent.

The first thing you want to do is purchase baling wire. It cost me about $3 for a couple of meters at Home Depot or Lowes.  It is very cheap and will last you for a long time if you take care of it. I suggest using gloves, and eye protection when dealing with wire.

The amount of baling wire needed for each layer depends on the size of your tent and the number of layers. Make sure to cut accordingly as well.

You want to make sure about your size before purchasing (check the diameter of your poles).

1-3 Layers for a 3 season tent will do just fine in any weather condition.

Or if you use a bigger tent or want more layers, then opt to buy thicker wire or rope for insulation.

The best part is that this method is free! If you have extra insulation lying around, then use it!

This process has been used by many people and has proven to work for good temperature insulation in a cold environment.

There are no rules on where you should place the baling wire. I put two layers of wire in each corner as well as another layer across. Just make sure your tent is tight.


This will be your first layer of insulation for the tent walls, if you want to place more layers then use rope or thicker wire and roll it over the baling wire layer. Make sure the ropes are tight so there is no air gap between them and the wall. Try to make a crisscross pattern as seen in

It will keep your tent warmer than you think.

4. Use Reflective Insulations

There are many reflective insulation materials on how to keep your tent warm that you can purchase in different sizes and shapes. One of the best sellers is Space blanket. How does it work? How to keep your tent warm? They are great for keeping the heat in, how does a space reflector blanket work?

They are made of a thin mylar that reflects up to 90% of heat.

Very easy to install inside your tent, but there is one thing that pinches me is price, they are not crazy expensive. But if you are really on a budget, You can not go for this option.

5. Use a Tent heater

Don’t get confused here. We are not talking about electric or petrol heaters, but tent heaters that run on batteries. You can use a battery-operated lantern or light bulb inside your tent to keep it warm at night. How does this work? It’s simple! 

The light bulb emits heat. It will make your tent warm and you will be comfortable.

These heaters are great for camping, but you have to make sure that you use them wisely and do not overload the battery as it will drain your batteries quickly.

Use hot water bottle to warm your tent. Under the right conditions, a hot water bottle placed next to an open fire can be kept warm all night long. A single hot water bottle is not likely to heat an entire tent, especially if that tent is meant for multiple people, but it still works wonders when tucked in my sleeping bag at night.  

6. Sleeping pads

If you know what the best tent heaters are, Then I’m sure you know what a sleeping pad is because they are vital to keeping your tent warm in winter and snow conditions. They add insulation to your body’s contact with the ground. That helps in keeping you warmer and comfortable throughout the night.

It is a combination of foam and air or other materials to create an insulating layer between you and the ground.

Sleeping pads also have different types, how do they work?

The most common one is a self-inflating sleeping pad which has a main chamber with internal tubes that fill up with air when you are lying down on it.

It is very applicable in cold conditions, where you want your body to be warm. Also, snow camping has the advantage of keeping you well above ground level where you are less likely to freeze or sink into the snow and get wet.

7. Block Of Wood

Another simple way to protect yourself from the cold ground is to use a block of wood as insulation between you and the ground.

The idea here is simple, cut a chunk of wood a bit thicker than your sleeping pad or blanket. Then lie on top of it with your sleeping gear. How does this work? It’s very simple to understand! The wood acts as a shield from the cold ground and keeps you warm. This is a small step towards keeping your tent warm.   But I found that I could keep things comfortable by simply using my own body heat.  

8. Layers of Blankets

Using blankets and sleeping pads together will also keep you warm (here we go again!). But you have to use them wisely because they won’t work with thin materials. You need thicker pieces to build up layers that protect you against the cold ground.

9. Thermal Curtains

What if you do not have a tent and just want to insulate a simple structure? then thermal curtains are the way to go!

Thermal curtains usually come in an aluminum frame with insulated fabrics (polyester is common).

The idea is that you put one side of the curtain on your wall and the other side faces toward the inside of your room. This way, you have a reflective barrier that keeps heat in.

The curtains come in different versions, some with zippers to allow easy access while others are covered at one end for better sealing. It is up to you which would be more appropriate in your case.

I personally love thermal curtains because they are easy to use and you can adjust them throughout the year as needed. If your hangout place gets cold during that time, you can put them around. Then when it is warm enough you take them down and store them away.


But for using all of the above-mentioned methods we have to understand the process of head induction, how heat is transferred from one body to another body, that is very important for us if we want to keep our tent heated on cold nights.

I will explain it in simple terms. If you heat a spoon till it becomes red and after that, you suddenly put that in a cold glass of water, what will happen?

The heat from the spoon will transfer to the water. Why?

Due to the difference in temperatures, the same happens with us, when we are camping in a cold place, we have a temperature difference.

That’s why when we need to protect ourselves from extreme cold weather, we use the above-mentioned ways to keep our tents warm at night.
