How Cool Are Tesla Glass Roofs?

Tesla recently filed for a new patent for the glass in its very first truck, the Tesla Cybertruck. The patent suggested that the Cybertruck will have futuristic curved windows. Yesterday, Tesla also shared a video detailing the glass that serves as the roof of the Tesla Model 3 and Model Y. “Tesla glass keeps your cabin quiet, protects you from UV rays and can withstand 4x the weight of the car. ,” the company wrote in the description.

The video was shot at the Tesla Glass Technology Center in the Tesla Design Studio and opened with a demonstration of the acoustic performance of the new glass. You could hear the factory background noise disappear into complete, uninterrupted silence as the window rolled up. An engineer (name not shown) gave the tour and he explained that when the designers first sketched the Model Y, S, 3 and X, they sketched it from the front to the back of the vehicle.

The team spends as much time as it takes to ensure that each glass position has the correct curvature, size and shape.

“One of the coolest things we’ve done is put acoustic laminated drops on the side of every vehicle at Tesla.”

Acoustic laminated drops on the side are a reference to the type of glass Tesla uses. Acoustic glass is often used for sound insulation and is coated with resin or plastic to strengthen the glass and improve its acoustic properties. Some main benefits These types of glass include protecting a driver’s hearing, improving operator communication (think firefighters trying to hear the alert), adding comfort to the ride and increasing productivity.

He also described how the Tesla glass was made.

“What this consists of is a glass sandwich. You have a glass outside and a glass inside. And in between is an acoustic damping layer for road noise, wind noise, which the customer will experience and which makes the occupant feel quieter.”

Another engineer, Antonio, who is a Tesla Glass specialist, shared additional details. He explained that they combine a 2% tint used on roofs with different types of thin films that have properties to reflect radiation. They then combine this with standard polyvinyl butyral (PVB), which has other useful properties. Some have acoustic properties and others have solar properties.

“We have to be very careful about what we choose to go into the vehicle.”

The first engineer pointed out that safety is a big consideration.

“So we’re working with our exterior, our closure team to make sure it’s very safe for our occupants for things like rollover and roof-break testing. Next, we’ll go into the thermal aspects to make sure it gets the best thermal performance.

“The roof itself absorbs 99% of the UV rays that come in, so it’s amazingly safe even though you have this big open experience in your vehicle.”

He also added that the windshield will become a lens for the array of Autopilot cameras on the front of the car. For this, the team focuses on issues such as distortion and works with the Autopilot team on functionality, heating function and the diffraction of the images that come in.

“I’d say it’s part of how we lead the industry and set the standard for Autopilot functionality and the glass quality required for Autopilot.”

Rare glimpse of Cybertruck’s new windshield?

Teslaratis Simon Alvarez noted that while the Cybertruck was not mentioned in the video, he did show a clip of Tesla workers moving a huge piece of glass not used in Tesla’s current production vehicles and that the panel was easily larger than the glass components. used in models S, 3, X and Y.

The glass had a section for Autopilot cameras and appeared to be different from that in a Class 8 truck. The part of the glass assigned for Autopilot was very similar to that of the Cybertruck prototype, prompting Simon to point out that this was an extremely rare look at the Cybertruck’s giant updated windshield.

in 2016, Reuters reported that car door windows do not block UV rays and that car windows do not protect against harmful sun exposure. The article advised those in the car to wear sunglasses and sunscreen even while driving and pointed to a study on these topics. While windshields block most of the sun’s UV rays, car door windows do not. We may think that glass has always existed and glass is glass, but it is actually important that we see more innovation and improvement in glass for use in vehicles, for example.
