K-Flex Gray Duct Liner is a new closed-cell elastomeric insulation product from this company. According to company officials, the duct liner was improved by increasing its flexibility and by making it more user-friendly for sheet metal fabricators installing it on round or rectangular duct or on transitional sections manually. The duct liner allows fabricators to install insulation on flat sheet metal and then bend the metal and insulation together as they form the bends necessary to form ductwork. The product is also resistant to mold and mildew and is available in various widths to accommodate different duct sizes and connections.
