When the efficiency of an HVAC system is discussed, proper ductwork is often overlooked. But at the AHR Expo in Las Vegas, it was discussed plenty at the Johns Manville booth.
One of the products Johns Manville was showcasing was the LinacouSTIC® RC-IG, a flexible, fiberglass duct liner with a non-toxic, water-reactivated adhesive layer for easier, cleaner, and quicker duct liner installation on sheet metal, according to the company.
