Cheap car windshield

Types of cheap car windshields

A cheap car windshield is made from various materials, each designed to meet specific needs. They include:

• Tempered glass

  It is made by heating ordinary glass to high temperatures and cooling it quickly. The process puts the surface under pressure and the interior under tension. It is used in cars since it is harder to break than regular glass. When it breaks, it shatters into small pieces. It is safer than laminated glass.

• Polycarbonate

  It is a type of plastic used in cars for windows, especially in sports and luxury cars. It is not as clear as glass but is very strong and hard to break. It offers good protection against crashes. It is also lighter than glass, which is good for fuel efficiency. Polycarbonate is not used for front windshields because it scratches quickly and is not clear.

• Laminated glass

  It is made by putting a special plastic layer called PVB between two pieces of glass. This layer holds the layers together. It is used for front windshields because it is safer. If the glass breaks, the PVB layer keeps the shards in place. It protects the driver and passengers from injuries. Laminated glass is also good for hearing since it blocks noise from the road and is better for seeing through.

• Acoustic interlayer

  It is a special layer of plastic used between the glass layers in a windshield. It is designed to reduce noise inside the car. The acoustic interlayer absorbs sounds and vibrations. Cars with this interlayer have a quieter ride. It is mainly used in the side and rear windows.

• Wire mesh

  It is used in some car windshields for extra safety. The wire is sandwiched between layers of glass. It helps hold the layers together, like the PVB layer. The wire mesh adds strength and can stop small things from breaking the glass. It is often used in military and police cars.

Specifications and maintenance of cheap car windshields

A properly installed auto glass is important for the structural integrity of a vehicle. While the specifications of car windshields may differ, here are general standards that must be met.

• Material

  Windshields are made of laminated glass that has two layers of glass. The layers have a sheet of polymer sandwiched between them. The polymer is known as the interlayer, and it is stretched to absorb impact. It helps prevent the glass from shattering into sharp pieces. Windshields made of laminated glass reduce the risks of injuries in case of an accident.

• Thickness

  The thickness of a cheap car windshield can affect its strength. Standards set by the American National Standards Institute state that the thickness of the glass layers should be 3.2 mm. The windshield should also have a uniform thickness that meets this standard. Variations in thickness can compromise the windshield's ability to withstand impact.

• Size

  Windshields come in different sizes to fit different vehicles. They are measured according to height and width, which must be accurate to within a few millimeters. The size of a windshield is important because it determines how well it fits the vehicle. A properly fitted windshield helps maintain a vehicle's structural integrity.

• Curvature

  Windshields have a series of curves that affect aerodynamics and visibility. The degree of curvature is measured by the radius, which is the distance from the center of the curve to the glass surface. For front windshields, the radius of the major curve is between 1,000 and 1,200 mm. The radius of the minor curve is between 600 and 800 mm. For back windshields, the radius of the major curve is between 550 and 650 mm, and the minor curve's radius is between 300 and 400 mm. The curvatures ensure that the car windshield provides a clear view of the road.

• Coatings

  Some windshields have coatings that improve various features. For example, a coating can reduce glare from the sun or increase the glass's scratch resistance.

Following the manufacturer's instructions during maintenance helps ensure that the vehicle windshield functions properly. General maintenance tips include the following:

• Inspecting the windshield for chips or cracks
• Cleansing the windshield regularly
• Using a soft cloth and a mild detergent to clean the glass
• Avoiding the use of hard materials like steel wool when cleaning, as they can scratch the glass's surface
• Avoiding the use of products with high alcohol content because they can damage the polymer interlayer
• Using only repair methods approved by the windshield manufacturer

How to choose cheap car windshields

Business buyers should consider several factors when sourcing car windshasses to meet their customers' needs. These factors include the type of glass, vehicle compatibility, quality standards, and supplier reliability.

Firstly, buyers must know the different types of glasses used in windshields. Laminated glass is ideal for safety as it reduces the risk of injuries. On the other hand, tempered glass is suitable for its strength and durability. Both glasses provide excellent visibility, but laminated glass has an edge over traditional glass in terms of safety.

Secondly, the car windshield must be compatible with various vehicle models. Stocking windshields with a wide range of sizes and shapes to fit different vehicles will increase the customer base. Additionally, business buyers can source windshields specifically designed for popular car models.

Cheap car windshields don't compromise on quality. They should have industry certifications such as AS/NZS 2080: 2013, which show they meet quality standards. They also need to be tested for strength, safety, and optical clarity to ensure they are reliable.

Lastly, buyers should partner with reputable suppliers known for quality products and timely delivery. They can read reviews and testimonials from other customers to gauge the supplier's reliability. Furthermore, they can attend trade shows and exhibitions to meet suppliers in person and establish business relationships.

How to DIY and Replace Cheap Car Windshield

Replacing a car windshield is a complex task that requires precision, proper tools, and knowledge of safety standards. While it is advisable to have a professional handle the replacement, DIY is possible with the right conditions. Here are the steps to take if attempting to replace a cheap car windshield as a DIY project.

• Choose the Right Windshield

  Ensure the new windshield is compatible with the car's make, model, and year.

• Gather the Right Tools

  Windshield installation kit, razor knife, suction cups, urethane adhesive, primer, masking tape, and clean rags.

• Prepare the Vehicle

  Remove all the objects from the car that may get in the way during the replacement. Fold down the seats and put the seat covers in place. This will protect them from glass debris. It is also advisable to disconnect the vehicle’s battery before replacing the windshield, especially if the car's auto glass contains advanced features like heating elements.

• Remove the Old Windshield

  A windshield installation technician uses a razor knife to cut through the urethane adhesive and carefully break the glass using a suction cup. They then use the suction cup to pull the glass away from the car. Windshield removal should be done carefully to avoid damaging the car's A-pillar.

• Prepare the Frame

  Clean the pinch weld (the frame where the windshield sits) to remove debris, glass shards, and old urethane. Apply a primer coat to prepare the surface for the adhesive. Ensure the area is dry and clean before proceeding.

• Install the New Windshield

  Apply a bead of urethane adhesive to the pinch weld using a caulking gun. The bead should be about ½ inch thick. With an assistant's help, carefully position the new windshield using suction cups and align it to fit perfectly within the frame. Press the glass gently to create an adequate bond with the adhesive.

• Ensure Proper Adhesion

  Check the evenness of the urethane bead around the windshield's perimeter. Wipe away any excess adhesive with a clean rag. Allow sufficient time for the adhesive to cure before driving the vehicle. Follow the manufacturer's instructions for drying time and safe driveaway standards.

• Reconnect the Battery

  Once the windshield installation is complete and the adhesive is dry, reconnect the vehicle's battery.

• Perform a Leak Test

  After replacing the windshield, conduct a leak test to ensure a proper seal. Spray water around the windshield and check for any signs of leaks or water intrusion. If any issues arise, address them promptly to maintain the vehicle's integrity.
