What component is used to reduce sound transmission and prevent water leaks on a rooftop air conditioner installation?

The curb gasket is specifically designed to reduce sound transmission and prevent water leaks in rooftop air conditioner installations. It serves as a seal between the rooftop unit and the curb, which is the surface that the air conditioner sits on. By providing a flexible and durable barrier, the curb gasket effectively minimizes vibrations and sound that can travel through the structure, ensuring a quieter operation of the HVAC system.

Additionally, the curb gasket plays a crucial role in moisture management. It prevents water from infiltrating the interior of the building by sealing any gaps that could allow rain water or snow melt to enter. This is particularly important on rooftops where water pooling can occur, and where a reliable seal is essential to protect the building and its contents from water damage.

In contrast, the other options serve different purposes. Silicone caulk is great for sealing gaps and joints, but it is not specifically designed for sound attenuation or the unique challenges presented by rooftop installations. Roof flashing is used to direct water away from critical areas, but it doesn’t provide the same level of soundproofing or sealing as a curb gasket. Roofing tar is often used for sealing and waterproofing, but again, it does not provide acoustic dampening properties. Thus, the curb gasket is the most suitable choice for
