I was thinking it would be higher on the absorption.... Great info on the whole post though Tintguy -

Automotive Tint Comparison
MEP Films distribute Llumar in Australia. I for one have been using Llumar since 1984 and have very rarely had or seen any issues with quality and that is why the brand is my go-to the majority of the time. Sun Tek have some good automotive films that I like, but other than those, I am strictly a Llumar user. BTW Eastman Chemical own both Llumar and SunTek so I imagine their film technology may be somewhat shared. -

Better shop in Europe to buy Films and Tools?
Hi guys, Im new here and learning how to tint… I live in Europe and to find tools and tints to buy here is very difficult. I just got some tools and tint on this website: tintwrap.eu This website was the only one I could find some felt squeegee and high quality films with the best price to deliver in Europe without ripping me off. the delivery was quick, about 2 days. and the material was high quality as well. Do you guys have any other websites suggestions? Thanks -

Paint Protection Film (PPF) is it needed or worth it?
I've never had PPF done before and never had issues with the paint on the car looking bad. I usually park in the garage and have had Kia Casa White - Solid on my Sportage since 2015 and no noticeable issues with the paintwork. The new car is Glacier White - Solid I've been told that PPF is beneficial, but very few people I know have actually opted to get it for their cars. I've been told there are many benefits such as: No need to ever wax or use sealant after the coat is applied Stops the paint fading Makes cars super easy to wash Prevents Acid Etching from animal contaminants, hard water spots, tree sap UV Rays Acid Rain (although I don't think I've ever seen acid rain) Repels Water & Grime Saves Water Will not wash off, crack or peel Non-abrasive Self-Healing Properties: repair minor surface scratches and swirl marks on their own when exposed to heat. So is this all simply marketing spin to provide another product to the market without any noticeable benefits? Does the average family car really need PPF or is this more the reserve of the show car, tuner set, car aficionado niche?

Cracked glass
Follow up: Attached is the performance data for Johnson's Resi/Comm window films and if you look to the bottom you'll see DN50 has a solar absorption of 39%, which is well below the threshold of concern which is generally accepted as 50% absorption (with no shadow). With a straight line shading from the roof this does increase the risk, which is usually low for straight line shading compared to other types. I've also attached a pdf of Johnson's film-to-glass chart which is used to determine how safe a film is. The thicker the glass the higher the risk; you say 6mm tempered and 4mm is the cracked one (interior pane). The question now is what compass direction do these panels face? In the end, I'll just suggest you hook back up with the person that installed it and get his input. He had to have been comfortable suggesting that film. I still believe it's a one off cracked panel and the rest will be fine. It takes 2 seasonal cycles to know for sure. Truly your call as to whether or not to replace with something lighter such as DN60. Here's more helpful info that helps you question the glass type on the interior; is it plate or is it heat-strengthened (HS). I believe it is plate and not tempered or HS. Why? Plate glass with suffer thermal shock if the edge temperature is different than the center of the glass by 50 degrees F. Heat strengthened requires 100 degree F difference, and Tempered requires 200 degree F difference. Ryker chimed in and that stimulated further review. Good Luck with this. johnsonFilmToGlass_2021.pdf- 1

Whatever that glass is that cracked it is NOT tempered. DN 50 is pretty high solar absorption and your saying shadows too so you probably need a more reflective film.- 1

Automotive Tint Comparison
1) Why avoid Suntek? I thought they resolved that issued with the easy scratching and that they are one of the market leaders in Australia? Also, it seems most of the well established Tint businesses use Suntek 2) I've heard mixed things about Rayno, with some installers raving about it and others disparaging it. Makes it difficult for the consumer to know the truth, given vested interests exist. 3) Is Ultragard a Australian exclusive product? The IP seems to be owned by GTS FILMS PTY LTD. How's the quality as it seems to have limited installers. 4) Is the MEP Films CNP that apparently are Manufactured by LLumar of the same quality as the LLumar tints (such as Llumar Formula One Stratos; Llumar Formula One Pinnacle; Llumar CTX)? 5) -

Cracked glass
The crack indicates thermal stress, however, the edge of the glass may have an imperfection (bur or clam shell chip). The crack does run 90 degrees out from the edge and curves as it follows any weaknesses in the pane itself. I have attached a pictured of what tempered glass looks like when it breaks and alongside it what a plate (or float) and heat-strengthened glass looks like when it breaks. The outer panel my be tempered should indicate so by a stamp etched on the glass surface in one corner. It should indicate tempered. Plate glass has no indicators, however, heat-strengthened glass will crack in the same manner as plate glass. I'm an unsure whether heat-strengthened glass requires a stamp. Tempered glass is 4 times stronger than plate and heat-strengthened is 2 times stronger than plate. 1 in 24 is indicative of edge imperfection. I could not find the solar absorption rate of DN 50, but if it is similar to competitive films, there should be no issue with that installation setting (including a straight line shadow). This, too, points back to edge imperfection as the cause. And finally, I spy drapes in a close position, correct? If so, it would be helpful to crack open during sun exposure; this to assist in allowing trapped heat between the glass and drapes to dissipate.- 2

Cracked glass
Hello. I recently installed Johnson Daylight Natural DN 50 on a couple of windows. Solar energy rejection is 39%. The windows are double pane and the glass is supposed to be tempered 4mm + tempered 6mm. The roof overhang shades the top 1/3 - 1/2 of the windows. However, a few days after installation I noticed that one of the glass has cracked, presumably due to thermal stress. Should I remove the film from the rest of the windows? I installed the film on 24 of these windows (6 tiny houses) so now 1 out of 24 is broken. Or is it more likely that I just got unlucky and the glass had a defect? Is shading from the roof overhang such a big factor? The glass cracked. Is it really tempered? I thought tempered glass would shatter, but not crack. Thanks!
