Foil tape is always installed in which location?

• A. On the outside of the glass
• B. On the frame
• C. Under the floor
• D. Inside the glass

Answer: (D)

Foil tape is placed inside the glass to protect the tape from weather, wear, and tampering and to keep it concealed and secure. When the tape sits behind the glass, it’s not exposed to the elements or easily reachable, which helps maintain a stable seal and preserves the integrity of the installation. This placement also makes the setup less conspicuous and harder to tamper with, which is important for security systems.

Placing foil tape on the outside would make it visible and vulnerable, and on the frame or under the floor would not provide the same protection or concealment. Inside the glass avoids these issues and keeps the tape where it won’t interfere with exterior aesthetics or operations.
