How to Make an Insulated Smoker Blanket (5 Steps)

Competition barbeque involves a method of low and slow cooking. This technique requires a smoker to run at a steady temperature for long hours. The typical bullet style smoker is made from thin gauge metal and has no insulation. Building an insulated blanket for your smoker conserves fuel and helps to maintain a more steady temperature. These blankets are made from special insulation that has an aluminum covering and handles the heat without melting.

Things You'll Need

  • Measuring tape
  • 3/8-inch fiber insulation with reflective aluminum face
  • Aluminum foil tape
  • Utility knife

Instructions

  1. Measure the height of the smoker and add 2 inches to 3 inches to this measurement. Transfer that measurement to the narrow diameter of the insulation blanket and draw a line on the material.

  2. Cut the material along this line with a utility knife. Position the cut section around the smoker and mark the point where it meets the start of the insulation. Draw a line down the insulation at this point and cut to size.

  3. Hold the two sections together and fasten with aluminum foil tape on both sides. Place the insulation back on top of the smoker. Position another section of insulation on top of the smoker and draw the outline of the outside of the round insulation blanket.

  4. Cut along this line with a utility knife. Place the circular cut out over the insulation blanket and fasten with aluminum foil on the inside and out.

  5. Locate the bottom and top vents on the smoker. Remove sections of the insulation blanket around these areas to allow airflow in and out of the vents.
