Features of photovoltaic rooftop installation gasket: For prefabricated dry-construction rooftops, long-term relative movement exists between panels, so expansion/contraction and waterproofing are critical.

Solutions: 1) The gasket is integrally designed to fulfill multiple functions including water drainage and expansion/contraction; 2) The panel fixing points use single-point fixation, while other points are designed to accommodate relative displacement between panels.

To meet the requirements for high and low temperature performance due to seasonal weather changes and to withstand long-term expansion stress caused by panel movement under high-rise wind pressure, the product is made of highly tear-resistant silicone material, with a hardness of approximately 75–80 Shore A.
