Rubberworx Insulated Ducting is designed with multiple plies that are constructed using highly effective insulation materials such as polyurethane foam or fiberglass insulation. These layers provide a barrier between the ambient environment and the cooled air inside them, preventing heat loss through convection and radiation while also reducing condensation inside the system. Additionally, these layers add structural strength to the ducts, helping them maintain their shape and preventing damage that could lead to leaks or further losses of cooled air.
