Anyone have real specs on the windshield and front side windows of the NX250 (NOT THE HYBRID)?
Glass numbers are M8H4 for the windshield and M2H5 for the front sides.
The importance of good UV and IR blocking is so important to preserve the interior, save on AC cooling and keep the dreaded leg burns on hot pleather seats (oh how I miss the much better cloth seats). It is crazy in this day and age that IR blocking is not a requirement.
Please include a link to the actual specs.

 

I don't have specifications, but in general I can tell you that pretty much all windshields block almost all UV light because they are laminated as required by law. The lamination layer absorbs the UV. The side windows are not required to be laminated so you'll get either tempered or laminated so UV blocking may be partial to complete. Now I'm not sure if the same glass is on all NX models, but on mine I have laminated glass on the two front side windows and tempered glass on the two back side windows. You can tell simply by looking for the mark "temperlite" or "lamisafe" on the glass. That should mean near 100% UV block on front and front sides. Not sure about the rear side glass, since its tempered, but does have a factory tint. No idea how the tint affects UV passage. It obviously blocks visible light. Maybe if I get bored I will break out my IR camera and see if it shows anything interesting.

If you want to dig deeper, try researching the temperlite and lamisafe trademark names.

 

To a large extent, yes, particularly if double pane. You can get ceramic tint w/ UV mitigating properties to further control any straggling heat or UV. If your front-sides are not laminated, i think it's something like 65% blocking or something like that. finish it off with a nice tint.

 

I used my IR camera and the windshield was ~140 in the sun with the sides ~105. This could be due to the slight angle of the sides or the lack or IR protection in the windshield, while the minimal tinting in the sides helps. I reached out to AGC without a response back. AGC brags about the low-E glass for the Lexus e-cars, but I guess the rest of us just bake. Below is from AGC website.

"The special Low-E coating technology developed by AGC recently for automotive glass has cleared the reliability evaluation required for the LEXUS brand, which pursues high quality and advanced features. It has also achieved unprecedented solar control and heat insulation performance, thereby greatly reducing the heat in summer and cold in winter, which had been an issue. The shade-less configuration also contributes to vehicle weight reduction and head clearance (the distance from the top of the head to the ceiling when seated)."

 

This is on a 24 NX350h.

I was quoted $400 to have the windshield clear tinted with 3M Cystalline. Even the shop owner said it may not be worth it given it is my wife's primary car and it sits in the garage 23 hours a day..... I did have the front windows tinted (including the front small triangle shape windows) done, cost me $280 and worth every penny.

 

I found this looking at the Japan Lexus site. I hope it is for the US models too, and not only the cars sold in Japan. The glass manufacture for Canada built cars (AGC) is different than Japan built cars. BTW, the Japan Lexus website has half a dozen NX brochures that tell everything about the car. Good Info with detailed specs. I remember when car brochures where more than just useless pages of poorly represented color combinations and actually gave you real data and specs.

 

Update from Lexus, yet they still have not provided actual specs.


Not sure why real data is so hard to find. 3M tells you exactly what is the specs for their film.

 

We live in sunny Southern California where the UV rays, heat, and discomfort quickly overwhelmed the windshield and windows on our new 2024 NX 350h. I immediately had ALL of the glass tinted dark with Llumar Ceramic, manufactured by Eastman Performance Films, at a higher-end tint shop in Costa Mesa.

I paid $800, which is well worth protecting my vehicle's interior and the overall comfort of the ride.

 

I get it. Sad the manufactures don't get it, for the added cost for thermal blocking IR glass when they build the car is a few dollars and will likely save hundreds in gas from reduced AC use, plus make the interiors last longer and cars more comfortable. It is clearly a no brainer. And worse yet is Lexus used to brag about the IR glass in their old brochures. No longer. Aside from the better looks inside and out and few more standard whistles and bells, no real difference between a toyota and lexus.

 

Yep, it makes a big difference in interior temp. Now I am thinking if I should get the windshield done with clear 3M Crystalline…….$400 though….

 

@SoCalSlim I'm ready to get my windows tinted as well. I'm in Central Florida and the UV and heat is ridiculous. I have a 23 NX450H+ Base and it has the tinted side windows. Can I ask what color and level tint you had installed? I know I'm looking at ceramic but being color blind, I'm not sure what color I have to match. I also don't know if I should get 15%, 35% or whatever the numbers are. So I figured you being in So. Cal you can understand our heat and UV. Thanks in advance for your help.

 

Be aware that many states prohibit tinting the front windshield regardless of how dark. Because your goal is heat reduction (and not a dark window that would draw attention), I would stick with the lightest tint available, like Crystalline 90 that has excellent heat rejection properties much better than standard ceramics. All the tints have near 100% UV blocking and the color is more due to the material and brand you choose. Some are blueish and others more neutral. If you do the windshield and the front side windows all the same, the minor tint color will be unnoticeable. The 3M web https://www.3m.com/3M/en_US/p/d/b00016683/ is a great source of info, however in general, the better the heat rejection the more money. Most of the extra cost is the profit for the tint shop, so call around for prices. There are lesser quality tints than 3M that they tend to push them, for they cost the installers much less money, therefore more profit. Before you pull the trigger, look at the brand and type they are using and compare published heat rejection numbers. The installers lie or are just misinformed on the facts. Also, whatever brand and type you decide on, inspect the box the installer is using to make sure that the product is what you agreed on. Many will claim to use one, but use another betting you can't tell the difference. Also, be leery when someone claims high numbers for heat (total solar energy) rejection. 3M Crystalline is by far the best there is, and the Crystalline 90 blocks less than half (46%), so realize that tinting the window will help a great deal, it will not stop all the heat from coming in. Also be aware that the reflective sun shades you put into the window will have less benefit for the solar energy reflected back at the window gets reflected right back in the car. This may be more than you were asking for, but gives you an unbiased overview.

 

@AtomicLexus Thanks, that is good info. I had Xpel Paint Protection Film installed on the complete front end 2 weeks ago.
I am taking the car in tomorrow for a carwash and they'll do a 2 week check up on the PPF. When I took the car in to have the PPF applied I was looking at their Xpel Window Tint. https://www.xpel.com/products/window...q=ceramic-tint.

Not sure if I'll get it yet but am really considering it. It is pricey. They were telling me the glass on the car is only a colored glass and doesn't have a heat or UV protector. The windows Rear and all 4 doors is $600. If I want the windshield done it's $400. They told me that you're not supposed to cover the windshield but if you decide to do it, it's best to cover the whole windshield, it makes it less noticeable and chances are no one will ever know. All have a life time warranty. We didn't talk about the Florida Law so I'm not sure about that. My concern is the color. I found this website but I don't know what the factory provided in the side and rear windows already to know what I can put on. https://www.tinting-laws.com/florida/

 

Look at my earlier chart provided by Lexus. The windshield and front sides all have UV protection, and some solar energy blocking, but to what extent of solar blocking they would not say. Lexus and AGC are very reluctant to provide full specs. We can't handle the truth. I did thermal camera tests and found the front door glass was exceptionally good at blocking heat, and the windshield not so much. However, my Prius windshield blocked heat much better. Food for thought.

 

@AtomicLexus Thanks. I looked at them but never payed attention that the color was listed. I did see that there was no real information provided though. But I appreciate the response. Just need to make up my mind as to have it done or not.
