Insulating 2 Types of Smokers: Vertical & Horizontal

When it comes to smoking meat, the type of smoker you have plays a big role in how well it retains heat and how much insulation it needs. There are two main types of smokers: vertical and horizontal. Each type requires a different approach to insulation.

Insulating a Vertical Smoker

A vertical or bullet smoker stands upright and typically has several racks to hold the meat. Because the heat source is usually located at the bottom of the smoker, vertical smokers tend to lose heat quickly, making insulation a necessity.

Here’s how to insulate a vertical smoker:

  • Measure the smoker: Before you start insulating, measure the height and width of your smoker to determine how much insulation material you’ll need.
  • Choose insulation material: There are several options for insulation material, such as welding blankets or insulation jackets. Make sure to choose an option that’s heat-resistant and appropriate for outdoor use.
  • Prepare the smoker: Clean the smoker thoroughly before adding insulation. Remove any old insulation or debris.
  • Apply insulation: Cut the insulation material to fit the size of the smoker. Use adhesive to attach it to the sides of the smoker, making sure to cover as much surface area as possible.
  • Cover the insulation: To protect the insulation from the elements, cover it with a waterproof material, such as a tarp or weather-resistant cover.

Insulating a Horizontal Smoker

Horizontal smokers, also known as offset smokers, have a horizontal barrel shape with a firebox on one end and a smoking chamber on the other. Heat and smoke travel through the smoking chamber to cook the meat. Because the heat source is located to one side, horizontal smokers also need insulation to maintain a consistent temperature.

Here’s how to insulate a horizontal smoker:

  • Measure the smoker: Measure the length and width of the smoking chamber to determine how much insulation material you’ll need.
  • Choose insulation material: Options for horizontal smokers include insulation blankets, cement boards, or barbecue gaskets. Make sure the material is heat-resistant and outdoor-appropriate.
  • Prepare the smoker: Clean the smoker thoroughly and remove any old insulation or debris.
  • Apply insulation: Cut the insulation material to fit the size of the smoker. Use adhesive to attach it to the sides and top of the smoking chamber.
  • Insulate the firebox: To ensure heat is distributed evenly throughout the smoker, it’s also important to insulate the firebox. Use heat-resistant insulation material to insulate the inside of the firebox.
  • Cover the insulation: To protect the insulation from the elements, cover it with a waterproof material, such as a tarp or weather-resistant cover.

Insulating your smoker is important in achieving consistently cooked, flavorful meat. Whether you have a vertical or horizontal smoker, following these steps will help you insulate your smoker like a pro.
