Do You Need to Insulate a Smoker?

Before you can proceed and learn how to insulate the inside of your smoker, you must be wondering if it is even necessary to do so.

The answer is yes!

It’s essential to have your smoker insulated correctly to be able to enjoy thickly smoked and richly flavored meat.

Very often, the perfect temperature and level of smoke that brings you your tasty meat are disturbed by many external factors, the most common one being winters.

The cold temperature of winters messes with the temperature of your smoker, reducing the amount of smoke produced, and subsequently affecting the smokiness and taste of your meat.

Not just that, other than winters, this problem can occur due to poor insulation of the smoker in any weather if the smoke is easily allowed to escape your smoker.

This means that if you invest in good smoker insulation, you will not only be saving your meat’s worth but also saving your fuel!

4 Ways to Insulate a Smoker

1. Insulation Jackets

Insulation jackets are one of the most popular ways to insulate your smokers. This is because insulation jackets are insulated with aluminum foils, which is a great insulating element.

Another reason why they are commonly used is because manufacturers make insulation jackets based on different brands of smokers to ensure a perfect size and fit, and are available for all and any smoker brands.

For instance, we can assure you that the Stanbroil Thermal Insulation Jacket is the best choice for Traegar BAC344.

As long as your insulation jacket doesn’t cover the firebox of your smoker, it is safe to use.

2. Insulation Blanket

Insulation blankets are similar to insulation jackets in their method of insulation, since they also use aluminum foil insulation.

However, the positioning of the aluminum foil is what makes the two different.

For the aluminum foil positioned on the outside of an insulation jacket, an insulation blanket has it on the inside, or the underside of the fabric that makes the insulation jacket. But this positioning makes no difference to the insulation process of the two.

Both methods are equally good for insulating. The only reason why someone might prefer an insulation blanket over an insulation jacket is if they want to avoid the hassle of looking for the perfect fit of an insulation jacket for their smoker.

We highly recommend that you get yourself the Masterbuilt MB20100513 for the best insulation experience.

3. Welding Blanket

If you don’t want to invest in an insulation blanket or jacket, you’re luckily covered if you have a welding blanket.

If you’re unaware of a welding blanket, it is a common construction supply that protects welders from the heat as well as the sparks that result from welding.

Surprisingly, these welding blankets have more than one way of being useful to you.

These welding blankets work perfectly fine if used as insulation blankets for smokers! Just like an insulation blanket, you don’t even have to worry about the right size or fit in a welding blanket.

If you don’t happen to have one but are still looking to purchase it so that you can use it for more than one purpose, we recommend that you purchase one from the ABN store.

4. Cement Board

Cement boards come handy for insulating fireboxes of smokers, since all three options mentioned above are highly dangerous if placed anywhere near the firebox.

Cement is not only a great insulation material, but also highly durable against heat, which is why it is best used to insulate the fireboxes of smokers.

These fire-resistent cement boards can be easily built by measuring the insides of a firebox and using those measurements to place perfectly sized boards inside the firebox.

Luckily, whether it is rain or winds, or even just winters around the corner, the methods of smoker insulation have you covered in all aspects.

With good insulation, you can ensure that not only is your smoker well-protected, but it also gives you the best in terms of food.
