Resilient channel drywall is a type of drywall that is designed to be more resistant to damage than traditional drywall. It is made with a layer of galvanized steel that is sandwiched between two layers of gypsum board. This makes it more resistant to fire, water, and impact. Resilient channel drywall is often used in commercial applications, such as hospitals, schools, and offices, where there is a need for a durable and fire-resistant material.
