Red Seal Glazier Practice Exam

Silicone-based adhesives are commonly used in structural glazing due to their superior bonding capabilities and flexibility. These adhesives provide excellent performance in a variety of conditions, especially where movement and expansion can occur, as they maintain their elasticity over time. This is particularly important in structural applications, where the materials may undergo thermal changes that can cause shifts in their alignment.

Silicone adhesives also exhibit impressive resistance to environmental factors, including UV light, moisture, and temperature fluctuations, which further enhances their durability in outdoor applications. Additionally, they can bond well to a variety of substrates, including glass and metal, making them a versatile choice for structural glazing.

Other types of adhesives, while useful in different contexts, do not provide the same level of performance required in structural applications. Consequently, silicone-based adhesives are favored in the glazier industry for their properties that align with the demands of structural glazing requirements.
