Red Seal Glazier Practice Exam

Edge sealing plays a critical role in ensuring the longevity and durability of glass installations. The primary purpose of edge sealing is to prevent moisture ingress, which can lead to various issues such as corrosion, delamination, and deterioration of the materials surrounding the glass. When moisture penetrates the edges of sealed glass, it can cause a breakdown of the adhesive that holds the glass together, ultimately compromising the integrity of the entire installation.

By effectively sealing the edges, the installation becomes more resilient against environmental factors and potential damage, enhancing the overall durability. It also contributes to maintaining the aesthetic quality of the glass over time, as moisture accumulation can lead to unsightly spotting or blemishes. In essence, edge sealing is essential for protecting the glass and ensuring that it remains functional and visually appealing throughout its lifespan.
