Is Taping Windows Really Effective During a Typhoon? What Is the Correct Method?

Does Taping Really Prevent Glass from Shattering?
First, it is important to clarify a core conclusion: taping windows does not significantly increase the wind pressure resistance of the glass. In other words, it cannot prevent glass from shattering under strong winds. According to the national standard for tropical cyclone grades issued by the China Meteorological Administration (CMA), the maximum wind force near the center of a typhoon can reach Force 12 or higher. This level of wind pressure far exceeds the design limits of ordinary residential glass. If the wind is too strong or if flying debris strikes the window, taped glass will still break.
So, why is taping still recommended? Its primary purpose is "anti-splatter." When glass unfortunately breaks, the tape holds the shards together, preventing sharp fragments from flying around and injuring people. It also slows down the falling speed of the debris to some extent, buying precious seconds for evacuation or taking cover. Therefore, taping is an emergency measure to reduce secondary injuries, not a fundamental method for reinforcing windows.
The Scientifically Correct "Rice Character"
If you decide to take this protective measure, please ensure you use the correct taping technique. Incorrect methods are not only ineffective but may also make cleanup more difficult.
- Prefer the "Rice Character" (m) PatternThis structure distributes stress to the greatest extent and provides all-around tensile support when the glass breaks.
- Tape Selection: It is recommended to use wide, strong cloth-based duct tape or specialized wind-resistant tape. Ordinary transparent office tape has insufficient adhesion and breaks easily, resulting in poor effectiveness.
- Coverage Area: The tape should extend to the edges of the window frame, ensuring that the stress points are anchored to the frame, not just stuck to the glass surface.
- Both Inside and Outside: If conditions permit, apply tape to both the interior and exterior sides of the window for double protection. However, residents on high floors must prioritize their safety when working on the exterior; do not lean out of the window.
Protective Measures More Important Than Taping
Compared to post-event remedies, pre-event hardware inspections and safety awareness are more critical. Before a typhoon arrives, please focus on checking the following:
- Clear Window Sills: Remove all flower pots, clutter, and other items from window sills to prevent them from being blown off and becoming dangerous falling objects, or from striking your own or your neighbors' windows.
- Check Sealing: Inspect whether the window frames are loose and if the sealing rubber strips are aging. If there is significant shaking, temporarily reinforce the gaps with wooden wedges or hard cardboard.
- Stay Away from Windows: During a typhoon, regardless of whether the windows are taped, people should stay away from wind-facing windows as much as possible. If cracks appear in the glass or unusual noises are heard, immediately evacuate to a room without windows or a small enclosed area such as a bathroom.
It is worth noting that standards for school and work suspensions during typhoons may vary by location; please refer to announcements from local governments. While paying attention to disaster prevention tips, please closely monitor official warning signals. Real-time typhoon tracks can be queried at TyphoonSays (taifengshuo.com)
