This basic tutorial shows how to install Aluminum Cut & Rolled Metal Jacketing over fiberglass pipe insulation. The metal jacket protects the pipe insulation from the weather, UV, and mechanical abuse. The guide also shows how to install an aluminum 90 degree elbow cover with use of fab straps to hold it in place. We recommend sealing all seams, overlaps, and fitting cover joints with aluminum color silicone caulk. **** Visit us at www.BuyInsulationProductStore.com ****
