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

Busting the Myth: Tape Does Not "Reinforce," Its Core Purpose Is "Splash Protection"
First, it is necessary to correct a widespread misconception: taping windows does not significantly enhance the wind pressure resistance of glass. Facing strong winds of Force 12 or higher near the typhoon center, the design limits of ordinary residential glass are easily exceeded. If subjected to direct strong winds or impact from flying debris, glass may shatter regardless of whether tape is applied.
The true value of taping lies in reducing secondary injuries. When glass unfortunately breaks, the adhesive force of the tape can temporarily hold the fragments together, preventing sharp shards from splashing around like shrapnel and injuring people. It also slows down the rate at which fragments fall, buying precious reaction time for occupants to take emergency shelter. Therefore, this is an emergency measure for "damage reduction" rather than "reinforcement."
Standard Procedure: Scientific Application and Material Selection
If you decide to take this measure, incorrect application is not only ineffective but may also increase the difficulty of post-disaster cleanup. Please follow these standards:
- Prefer the "Rice Character" (m) PatternThis structure distributes stress most evenly. Using the center of the glass as the origin, extend tape towards the four corners and the top, bottom, left, and right edges to form a 'rice' character. This structure provides maximum all-around tensile support.
- Choose the Right Material: Discard ordinary transparent office tape, which has weak adhesion and breaks easily. It is recommended to use wide, heavy-duty cloth-based duct tape or specialized wind-resistant tape, as their toughness and adhesiveness are better suited to withstand extreme weather.
- Key Details: Both ends of the tape must extend to the window frame edges and be firmly adhered, ensuring that the stress points are fixed on the frame rather than just staying on the glass surface. If conditions permit and safety is ensured (residents on high floors are strictly prohibited from leaning out of windows), double-sided taping (inside and outside) can be implemented to provide dual protection.
Fundamental Solutions: Hardware Inspection and Priority of Shelter
Compared to post-event tape remedies, pre-event hazard inspection and correct shelter awareness are more critical. Before the typhoon makes landfall, please perform the following checks:
- Clear Window Sill Hazards: Completely remove flower pots, clothes hangers, and other clutter from window sills and balconies to prevent them from being blown off and becoming "high-altitude bombs," which protects others and avoids reverse impact on your own windows.
- Reinforce Loose Components: Check if the window frames are shaky and if the sealing strips are aging. If significant looseness is found, you can temporarily fill gaps with wooden wedges or hard cardboard to reduce the risk of resonance.
- Establish Shelter Principles: During a typhoon, regardless of whether windows have been treated, personnel should stay away from windward windows. Once you hear unusual noises from the glass or discover cracks, immediately evacuate to small enclosed areas without windows, such as bathrooms or corridors, for shelter.
In addition, regarding measures such as school suspensions, work stoppages, and traffic controls during typhoons, implementation standards may vary by location. Specific arrangements are subject to announcements by local governments. While mastering disaster prevention skills, please closely monitor the latest warning signals issued by official authorities.
