                              Smoker Welding Blankets Buyer’s Guide 

                              Purposes of a Welding Blanket

                              Typically, welding blankets are used as a layer of protection in the welding process. But since it has components that could shield smokers from harsh temperatures and harmful elements, it is often used as kitchen equipment covers. It can also be used as insulation blankets to maintain consistent heating in the cooking chamber. 

                              Material Type


                              As you may have noticed in the list, fiberglass is the most common non-melting material used in typical welding blankets. Why? Because this type of clothing has great resistance to high heat, and it’s all thanks to its tightly weaved glass fibers [1]

                              However, remember that some uncoated blankets can irritate your skin, so we advise you to be selective when buying this variety. 


                              Other materials you may encounter when shopping for the best welding blankets for a smoker are leather. It’s a no-brainer that this material has high-temperature resistance, but did you know that it also doesn’t need extra coating? Unlike glass fibers, its surface is smooth. On the other hand, they can be very expensive. 


                              Another alternative welding blanket variety you can try are the ones made with felt textiles. Like leather, we noticed that this clothing has a smooth surface. Carbon felt blanket options are generally capable of handling temperatures up to 1800 degrees, and they’re also very cheap. The only downside for this textile is it’s not as durable as glass fiber threads.


                              These types of blanket options can withstand at least around 1000 degrees Fahrenheit. As it has much less temperature capacity, our resident chefs would only recommend this medium-level cooking and storage environments.


                              If you want your smokers to resist oil components, the best welding blanket for smoker grills that you should buy is a fabric made out of silicones. Although it has high heat tolerance as well, it can only handle between 500F to 1000F. 


                              Another alternative to glass fiber types is the vermiculite welding blankets. It has less shedding and definitely has lesser chances of irritating your skin. With heavier fabric weight, these options can add a strong layer of protection to your smokers. 

                              Heat Resistance

                              For kitchen equipment that is often exposed to high temperatures, you’ll need a welding blanket that can insulate the heat. Selecting non-heat-resistant clothing to cover your smokers will not only ruin the fabric but also potentially stain and damage your cookware. 

                              Depending on the blanket material we discussed, your welding blankets can resist a high-temperature range up to over 2000 degrees Fahrenheit.  

                              Temperature Resistance

                              Heat isn’t the only dilemma when maintaining your smokers. Cold weather can be your biggest enemy too! Many welding blankets claim to resist heat, but keeping your smoker in tiptop shape requires covers with all-out temp resistance.

                              You can assess your needs by evaluating the specs of your cookware and the environment you’ll put the smoker in.

                              Flame Retardancy

                              Apart from resisting extreme temperatures, the flame retardancy of your blanket must be on point. These are the substances that can prevent flames from spreading in the event that your blanket’s resistance to high temperatures results in burns and cause a fire.

                              How to Properly Clean Welding Blankets

                              When washing the best welding blanket for smoker grills, we recommend using a bleach-free detergent. Like any fabric, bleach detergents and typical soap can ruin the quality of the welding blankets. 

                              If you’re not sure how to spot bleach-free detergents, our team urges you to check the label of the products' label. 

                              Can You Cut a Welding Blanket?

                              Yes, you can cut welding blankets. However, cutting its material may cause the unraveling of reinforced hems. If you can, our experts advise reading the manufacturer’s instructions. 

                              You see, some welding fabrics come with labels indicating if they’re good for cutting. Some options will advise you to leave it at the same size and fold it during usage. 

                              Are Welding Blankets Waterproof?

                              Not all welding blankets are fully waterproof. At best, these fabrics are water-resistant. Keep in mind that the main purpose of these covers is to protect smokers from harsh temperatures and harmful components. 


                              How do you wrap a smoker with a welding blanket?

                              To wrap a smoker with a welding blanket, all you need to do is snug it and place it tightly around the grill’s body. You can wrap it the same way you use typical insulation jackets. No need to bother with custom fits. Ensure that it covers the cookware exterior for an enhanced heating consistency.
