What is the main purpose of a curb gasket in a heat pump installation?

The main purpose of a curb gasket in a heat pump installation is to prevent leakage and sound transmission. When heat pumps are installed on rooftops or curbs, the gasket creates a seal between the unit and the curb surface. This sealing action helps to minimize air leakage, ensuring that conditioned air remains within the system, while also reducing the potential for outside air to enter, which can negatively affect efficiency and performance. Additionally, by providing an effective barrier, the curb gasket helps to reduce vibrations and noise that could otherwise travel between the unit and the building structure. This contributes to a quieter operating environment, which is especially important in residential areas or near noise-sensitive environments.
