Insulating blankets are a great way to maintain the internal temperature of your smoker in freezing weather conditions. 

But which one should you buy?

What are the best insulating blankets for smokers? The best insulating blankets for smokers have a form-fitting canvas that completely covers the grill. Try using thermal insulators from Smokehouse, Stanbroil, BBQ Butler, QuliMetal, Green Mountains Grill, Camp Chief, and more for the best results. 

Read below to learn more about insulating blankets, how they work, whether they are as effective as advertised, and a recommendation list for the best insulating blankets available right now! 

What Are Insulating Blankets?

Insulating blankets are made from a combination of pliable heat-resistant and insulating materials. 

This jacket can be put over heat sources to improve thermal efficiency. In other words, it helps trap heat and is an excellent tool for BBQ grills. 

How much difference do thermal blankets make? A lot!

Imagine cooking a steak or smoking a brisket inside a fridge, because that’s exactly how you would be BBQing during the colder months. 

The heat would still be focused inside the cooking chamber, but the cooler ambient temperatures will continuously and slowly cool down the outside of the grill.

The cold temperature will eventually reach and affect the main chamber which will greatly impact the surface temperature of the food and can also result in higher fuel costs.  

Cooking With And Without Insulation

Some people believe that thermal blankets are just a gimmick and a way for companies to make a quick buck. 

However, in this case, these products truly do work! 

The difference between cooking with and without insulation can have an impact on the following:

  1. Doneness
  2. Bark
  3. Juiciness


You can expect an equal distribution of heat when using an insulating blanket that is designed to trap heat. 

Contrary to belief, insulating blankets won’t cause the steak or food to burn due to a higher buildup of heat, especially on a cold day. 

You can easily monitor and adjust the internal temperature of the grill using thermometers; even without them, if it’s sufficiently cold outside, the blanket will work effectively. 

But cooking in freezing temperatures without an insulating blanket will usually result in uncooked meat or improperly cooked meat that doesn’t form an adequate bark.


The bark will likely take on most of the negative impact when cooking without an insulating blanket.

To get an even and adequately thick bark, you need a constant flow of hot air and stable temperatures — which you can achieve using a thermal blanket. 

Remember, the seasonings and juices are not going to caramelize or go through the necessary chemical changes without heat! 


When you combine the failure of the above two characteristics of a beautifully cooked steak, you will also likely end up with a less succulent piece of meat that is not cooked through or is too dry around certain areas.

Buyer’s Guide For Insulating Blankets For Smokers

Now that we have established the importance of using insulating blankets, here’s a quick buyer’s guide to help you pick the best insulating blankets for your smoker. 

Please go through all of these tips before making a purchase decision:

  1. Choosing The Right Size
  2. Choosing The Right Material And Features

Choosing The Right Size

The most important aspect of insulating blankets is that you need to get the right size for your particular grill. Fortunately, there are several options to choose from! 

You can find specific thermal blankets that are made for particular grills. These blankets are designed to perfectly fit the exterior of the grill without letting in cold air.

Putting on a loose blanket without properly securing it would make a huge difference in the cooking time and the doneness of the meat.

And don’t even get us started with the struggles of dealing with a small-size thermal jacket that doesn’t cover the grill components!

Choosing The Right Material And Features

Insulting jackets are usually made of fiberglass, Reflectix film layers, heavy gauge polyethylene, or other composite materials that provide greater thermal resistance and insulation — and are even water and oil resistant.

Most thermal blankets that are specifically built for grills sell for around $70 or more. You can even find some general application insulating blankets that sell for $25, but these general blankets are only designed to superficially cover the grill. 

They might not be suitable for long-term use, but can save a lot of time in emergencies and can also positively impact the characteristics of the meat. 

Always go for insulating blankets that have cut out for handles and other openings around the grill.

The best blankets also come with magnets to stick onto the surface of the grill along with hooks and other securing mechanisms that keep the jacket in place. 

Also, do not use insulation products when the outside temperature is 40°F or you might easily overcook the meat.

If you don’t already have a set of thermometers, then we highly recommend that you purchase one, especially when cooking with the blanket on. Here’s a great set to get started!
