Red Seal Glazier Practice Exam 2026 – Complete Guide for Your Test Prep

Laminated glass is known for its sound control and impact resistance properties. This type of glass consists of two or more layers of glass with an interlayer, typically made of polyvinyl butyral (PVB), which holds the layers together. This interlayer not only provides strength but also dampens sound waves, making laminated glass effective in reducing noise transmission from outside to inside a building, thus enhancing acoustic comfort.

In terms of impact resistance, the interlayer helps prevent the glass from shattering upon impact, which is particularly beneficial for safety and security applications. When broken, the interlayer holds the glass fragments in place, minimizing the risk of injury from sharp shards and providing a barrier against forced entry.

While laminated glass may offer some improvement in thermal properties, its primary distinction lies in its ability to reduce sound and withstand impacts, making it a popular choice for environments where safety and noise reduction are priorities.
