Reasons for Panoramic Sunroof Leakage?

[MacWeston]

Panoramic sunroof leakage may be caused by clogged drainage holes, improper sealing between the sunroof and the weatherstrip, or aging of the weatherstrip. Below are some drawbacks associated with panoramic sunroofs: 1. Prone to becoming an oven: While panoramic sunroofs offer excellent brightness, direct sunlight can significantly increase the interior temperature. 2. Difficulty in noise control: The thin glass provides less insulation against external noise compared to traditional roofs, resulting in noticeable wind noise during driving, especially the distinct pitter-patter sound of rain. 3. Weatherstrip aging leads to leaks: Compared to standard sunroofs, panoramic sunroofs use larger weatherstrips and adhesives. Prolonged exposure to sunlight and improper maintenance can accelerate aging. Unlike conventional roofs that rely on drainage channels, panoramic sunroofs primarily divert water along the adhesive surface, lacking dedicated drainage paths, which over time can cause seepage issues.
