What is the primary function of a curb gasket in air conditioning installations?

The primary function of a curb gasket in air conditioning installations is to prevent water leaks. The curb gasket serves as a sealing mechanism between the air conditioning unit, typically a rooftop unit, and the building's curb or mounting surface. This is crucial because, without an effective seal, water can infiltrate the building, leading to potential water damage, mold growth, and other serious issues.

The design and material of a curb gasket help ensure a watertight barrier, which is particularly important in environments where rain or snow could expose the unit to water. Installation of a properly fitted curb gasket is essential for maintaining the integrity of the HVAC system and protecting the structure from moisture-related problems.
