HeatShield Armor is pretty thick and heavy-duty, but still quite easy to work with using a pair of scissors.
The first step is to trim off ~1” of insulation from the outer edge of the metal skin. Depending on the diameter of the exhaust and whether you’re using 1/4” or ½” thick Armor, you may need to trim less or more.
It’s a good idea to test fit the Armor to see if the insulation is popping out of the seams, or if there’s not enough insulation to cover the entire pipe. A little trial and error here and some patience will result in a nice execution.
This smaller 2.5” diameter pipe required less trimming than the 3” side exhaust.
The insulation was trimmed properly and wraps entirely around without popping out. The HeatShield Armor is then secured with HeatShield Product’s Cable-Ties.
After tightening down the Cable-ties and snipping off the excess, the installation is complete.
