Red Seal Glazier Practice Exam

Question: 1 / 400

What is the purpose of a caulk joint in glazing?

To enhance the visual appearance of the window

To seal gaps and prevent water infiltration

A caulk joint in glazing primarily serves to seal gaps and prevent water infiltration. This is crucial because proper sealing protects the interior of a building from potential water damage, mold growth, and deterioration of building materials. The caulk acts as a barrier, ensuring that rain or moisture does not seep through the joints between glazing components and the frame, ultimately extending the longevity and performance of both the glazing system and the surrounding building elements.

While enhancing visual appearance, providing structural support, or allowing for thermal expansion are relevant considerations in glazing, they do not represent the primary function of a caulk joint. The main goal is to create a watertight seal, which is fundamental in maintaining a building's integrity.
