Latest update date: February 16, 10

Windshield is one of the most important parts of a car. It not only protects the occupants of the car from environmental impacts such as wind, rain, and dirt, but also ensures clear visibility for the driver. However, due to direct contact with the outside environment, the windshield is easily damaged by impacts such as impact, chipping or cracking. At that time, repairing or replacing the windshield becomes urgent to maintain protection and ensure visibility for the driver.

This article will cover important considerations when repairing or replacing a car windshield, helping to ensure the process is safe and effective, while also extending the life of the new glass.

The important role of windshields in car safety

The windshield is more than just a barrier against wind and rain; it is an essential part of your vehicle’s safety system. According to the Auto Glass Safety Council, the windshield contributes up to 60 percent of a vehicle’s structural strength in the event of a rollover. Here are some reasons why the windshield is important:

  • Structural Support: The windshield provides up to 30% of the vehicle's structural rigidity.
  • Airbag support: It acts as a support for the passenger side airbag when deployed.
  • Keeping people in the car: In an accident, the windshield helps prevent people from being thrown out of the car.
  • Ensure visibility: Windshield ensures clear visibility for safe driving.

Types of car windshield damage

Understanding the type of damage is essential to determining the appropriate repair method. Common types of damage include:

  • Chip: Small, circular break on the surface of glass.
  • Crack: A straight crack can extend across the windshield.
  • Bull's-eye: Circular damage with rings around the impact point.
  • Star Break: Cracks radiate from a central point.
  • Combination Break: Combination of chipping and cracking.

Notes when repairing or replacing car windshields

2. Professional windshield repair process

For minor damage, repairs may be possible. Here is a typical repair procedure:

  • Clean the area: Remove debris and moisture from the damaged area.
  • Injection of Resin: Use a specialized tool to inject clear resin into the crack or chip.
  • Resin Curing: Uses UV light to rapidly cure resin.
  • Polishing: Smooth the repaired area to blend in with the surrounding glass.

3. Replace windshield

When replacement is needed, the process typically includes:

  • Remove old glass: Carefully remove the old windshield without damaging the vehicle frame.
  • Preparation: Clean and treat the car frame to receive new glass.

4. Choose a reputable service provider

Choosing a reputable auto glass service is important. Consider the following:

  • Certification: Look for technicians certified by the Automotive Glass Safety Council.
  • Warranty: Ensure work is fully warranted.
  • OEM vs. Aftermarket: Discusses the choice between original (OEM) or replacement (aftermarket) glass.
  • Mobile Service: Many providers offer on-site repair or replacement services for convenience.

5. Cost and insurance factors

The cost of repairing or replacing a windshield can vary greatly:

  • Repair cost: Usually from 1 million to 3 million VND, depending on the extent of damage.
  • Replacement cost: Can range from 4 million to over 20 million VND for luxury cars or cars equipped with ADAS.
  • Insurance: Many comprehensive auto insurance policies cover windshield repairs at no extra cost.

Precautions

To reduce the risk of windshield damage:

  • Maintain a safe distance from the vehicle ahead to avoid flying debris.
  • Use caution when driving on gravel or unpaved roads.
  • Avoid sudden temperature changes, which can stress the glass.
  • Treat small chips immediately to prevent them from spreading.

Maintaining your vehicle’s windshield is essential to the safety, aesthetics, and overall integrity of your vehicle. By understanding the types of damage, repair options, and the importance of professional service, you can make informed decisions about keeping your windshield in top condition. Remember, a well-maintained windshield is more than just a cosmetic issue – it’s an important part of your vehicle’s safety system.

FAQ – Frequently Asked Questions

1. What material is the windshield made of and how is it constructed?

Modern windshields are usually made from laminated safety glass. The typical structure consists of two layers of 2mm thick glass bonded together with a 2.1mm thick polyvinyl butyral (PVB) layer in between. The total thickness usually ranges from 1mm to 0.76mm. This structure prevents the glass from shattering in the event of a strong impact, increasing safety for the occupants of the vehicle.

2. What is the average time to replace a windshield?

The average time to replace a complete windshield is usually around 60-90 minutes. However, the specific time can vary from 30 minutes to 2 hours depending on:

  • Range of vehicle
  • Technician experience
  • Complexity of ADAS system (if any)

After replacing, let the car rest for at least 1 hour for the glue to dry completely. See the article now: How to care for/clean a blurred, scratched car windshield fastest and most effective.

3. Can I drive immediately after replacing the windshield?

Although you can drive immediately after windshield replacement, experts recommend waiting at least 1 hour before moving your vehicle. Ideally, 24 hours is enough to ensure the adhesive is completely dry and the glass is securely attached. During the first 24-48 hours, avoid:

  • Car wash
  • Strong door opening/closing
  • Driving at high speed
  • Go over the rough road

4. Can a windshield damaged by an airbag deployment be repaired?

In most cases, windshields damaged by airbag deployment cannot be repaired and must be completely replaced. Reasons:

  • The impact force from the airbag is very large, causing complex cracks.
  • The glass structure was severely affected.
  • Protection in subsequent collisions is significantly reduced.

The cost of replacing glass in this case usually ranges from 5 million to 15 million VND depending on the type of vehicle and type of glass used.
