In normal weather, the window glass will not be broken by the wind. However, because the strength of the usual wind is small, there is indeed a situation that will not blow. What if you get high winds like a typhoon? In this case, there is a real possibility that the window glass will be broken by strong winds. Typhoons bring not only strong winds, but also flying debris and intense pressure changes. All this poses a danger to the glass.
If the glass is not firmly installed or there are problems such as quality, it is likely to break under strong winds. Which can cause harm to people and property inside. Typhoons come at certain times of the year. In order to prevent this from happening, it is very necessary to take appropriate protective measures. The following will describe in detail the reasons why glass is vulnerable to damage in typhoons, and explore effective protection methods.
The reason why glass is easily broken in typhoon
Strong wind pressure
We all know that typhoons are usually accompanied by strong winds. Do you know how strong a strong wind can be? Winds could reach 100 kilometers an hour or more. When strong winds hit buildings, they also create strong wind pressure. This pressure acts directly on the window glass. The larger the glass or exposed glass structure, the more likely it is to break due to excessive wind pressure. So if you live in an area near a typhoon, pay attention to the structure and size of the Windows in the house. A proper reduction of the area can effectively resist the pressure.
Barometric change
The change in air pressure caused by typhoons is also one of the causes of broken glass. When a typhoon passes, the outside air pressure drops rapidly because of the high speed of the strong winds. The air pressure inside the building is always stable. So the difference in air pressure inside and outside the building creates a pressure difference. The glass is threatened by poor airflow. If the glass window can not withstand this pressure difference, it is easy to break the glass.
Flying debris
Typhoons, with their strong winds, can easily pick up small objects. Leaves on the ground, or roof tiles, or even branches on trees, these can be blown off. Fragments of these objects hit the glass at high speeds driven by strong winds. And it had a tremendous impact. Some items have sharp areas that directly damage the glass. Especially in the urban environment, all kinds of external items can be blown up by the wind. The threat to the glass has become even greater.
Rain erosion
Typhoons are usually accompanied by heavy rainfall. Rainwater seeps in along the cracks in the window frame. And erosion of the joint between the glass and the window frame. It is likely to cause deformation or aging of the window frame. Coupled with the impact of strong winds, the stability and wind resistance of the glass are affected.
An effective measure to prevent glass from being blown in typhoon
Typhoon weather is sometimes unavoidable, so we need to prepare protective measures in advance. The following are several methods that can effectively prevent glass from being damaged in typhoons and protect indoor safety.
Install storm glass
Storm glass is a type of glass specifically designed to withstand typhoons and strong winds. Common types of windproof glass include tempered glass, laminated glass and composite glass. Laminated glass has a layer of PVB (polyvinyl butyral) or SGP (ionic polymer) sandwiched between two layers of glass. Even when impacted, glass fragments can be stuck to the interlayer. It can minimize the damage to indoor and outdoor personnel. In addition, the tempered glass has undergone special heat treatment, and the strength is several times higher than that of ordinary glass. Better able to withstand pressure differences and impact forces.
Use storm curtains or storm window panels
If you are not willing to use the high price of tempered glass or laminated glass. You can also choose to install storm shutters or storm window panels outside the Windows. These devices are usually made of aluminum alloy, tempered or other high-strength materials. Provides an additional physical barrier. Effective against the impact of strong winds and flying debris on the glass.
Add protective film
Sticking an explosion-proof film or safety film on the surface of the glass can effectively enhance the impact resistance of the glass. These membranes hold the pieces of broken glass together. It has a similar principle to laminated glass. However, laminated glass is adhered to internally when the glass breaks, and the protective film is adhered to externally. Both prevent flying debris from hurting people. In addition, the explosion-proof film can also enhance the toughness of the glass and increase its wind resistance.
Install protective netting or window grating
Installing a protective net or metal window grating on the outside of the window can effectively prevent wind-blown debris from hitting the glass. These devices can provide temporary protection in the event of a typhoon or as a long-term safety measure. Its service life is relatively strong, and it is more durable than the protective film. Therefore, the protective net or window grating can better protect the safety of children and pets.
Close and reinforce Windows
All Windows should be closed before the typhoon arrives. Maximize the protection of indoor people and property. At the same time, people in areas near typhoons should check the tightness of window frames and sashes every year. Make sure it doesn't get blown away easily by a typhoon. One way is to stick a cross or X shape on the glass, preferably in the center. Don't sound crazy about this approach. In fact, this method can reduce the risk of splashing when the glass is broken. Window frames can also be reinforced to ensure that the window lock device is in good condition. To increase the overall wind resistance.
Use double glazing or insulating glass
In typhoon weather, the use of double glass or insulating glass is also a very wise choice. Double glazing or insulating glass consists of two pieces of glass with an air layer in between. This structure not only provides better insulation, but also enhances the glass's resistance to wind pressure. This kind of glass can better distribute the pressure when subjected to wind pressure, reducing the risk of rupture. But at the same time, the cost of these two kinds of glass is also more expensive. Can be purchased on demand.
Regular inspection and maintenance
The condition of Windows and window frames should be checked regularly before the typhoon season. Check for cracks, aging, loosening and other problems. These problems should be replaced or repaired in time. Don't ignore this little problem easily. When the typhoon comes, this may be the key factor whether the glass will break. Therefore, especially in areas near typhoons, be sure to pay attention to the regular inspection and update of window frames. At the same time, it is also important to clean the drain around the window frame. Ensure that rain water can be smoothly discharged to avoid water erosion of glass and window frames when rain comes.
Emergency response
If the above glass or protection method is applied, the glass will still break. Then the following measures should be taken immediately to avoid causing more injuries and property losses.
Away from the crushing area
If the glass is broken, move away from the broken area immediately. First, protect yourself from debris. Especially if there are children or pets in the home, take them away from the broken area as soon as possible. To prevent them from getting hurt and running around.
Cover the break with wood or plastic sheeting
If the typhoon is still ongoing, wooden planks or plastic sheets can be used to temporarily cover broken glass areas. This can effectively prevent wind and rain from continuing to invade the room. But we must also pay attention to our own safety when we take countermeasures, and always put our own safety first. To choose a heavier, better quality fixed wood or plastic sheet, so as to ensure stability. So as not to be blown away or destroyed by the wind.
Turn off the power in the room
If the typhoon is accompanied by rain. And the rain has entered the room, but also need to pay attention to power safety. Rain intrusion is likely to cause short circuit or leakage of electric wires. For safety reasons, the indoor power supply should be turned off in time. Prevent electrical equipment from moisture caused by safety hazards. It also prevents the personnel from being electrocuted by mistake when they are panicked.
Contact a maintenance professional
After a typhoon, a professional glass repairman should be contacted as soon as possible to deal with broken glass and window frames. Professional work is left to professional people. Bring them in for a full inspection and repair. Ensure the safety of the living environment.
Sum up
Strong winds, pressure changes, and flying debris in typhoons can cause glass to break, endangering personal safety and property. In order to effectively prevent the glass from being blown by the typhoon, measures such as installing windproof glass, using windproof curtains or protective nets, and installing protective films can be taken. In addition, regular inspection and maintenance of glass Windows can be done to ensure the safety of glass. In the face of typhoon conditions, do not panic, or remain calm. Taking appropriate countermeasures can effectively reduce injuries and losses. To protect the health and property of the family.
