Question: 1 / 400

What is the function of a "drip cap" in glazing?

A decorative trim around the window

A cover that directs water away from the window frame

The function of a drip cap in glazing is to act as a cover that directs water away from the window frame. It is typically installed above the window to prevent rainwater from entering the framing system. By guiding water away from the window, it helps to protect the underlying structural components, preventing potential damage such as rot or mold, which can occur if water collects around the frame. Additionally, this feature is vital for maintaining the integrity and longevity of the window assembly, ensuring that it performs effectively in various weather conditions.

While decorative trim, insulation layers, and support structures are important elements in window installation, they serve different purposes than the specific function of directing water away to maintain efficacy and durability in glazing installations.
