This is also a new product that we now carry - PhotoSync Heat Transitioning Film, which is made by Prestige Film Technologies. Simply put, this window film's (tint) heat rejecting capabilities transform when sun is more intense.

We were the beta testers for the manufacturer for a good 2.5 years now, so we are very familiar with its capabilities...So how does it perform and how it differs from regular tint?

We put it to test to compare it with Porsche factory installed thermal insulated glass. The factory installed option costs $1125 (for rear glasses only) to the Porsche owner.

Here is our test:

Outdoor temperature: 72 degrees
Time during test: 4pm

Product: Spectra PhotoSync45
Shade: 45% VLT (visible light transmission)
IR Rejection: 98.5% IR Rejection at peak performance
Total Solar Energy Rejection: 65%

VS:

Porsche Thermal IR Glass
Shade: 30% VLT (visible light transmission)

**surface temperature measurements taken on passenger seat exposed to window with PhotoSync45 vs. rear seat exposed to window with Porsche Thermal IR Glass

TEST 1
PhotoSync45 measured at 1 Minute 39 seconds 85.6 degrees
Thermal IR Glass measured at the 2 Minute mark 87.8 degrees
Windshield exposed front dash measured at 2 Minute 35 seconds at 101.1 degrees

TEST 2
PhotoSync45 measured at 18 Minutes 52 seconds 86.3 degrees
Thermal IR Glass measured at 18 Minutes 5 seconds 91.4 degrees
Windshield exposed front dash measured at 19 Minute 35 seconds 106.8 degrees

love the attention to detail to prove the results

only wish you guys were out in the UK

occasionally when its sunny here - it gets actually proper hot !

Does the tint also work like a polariser for dazzle or glare from shiney surfaces
and does it work in the same way at night for oncoming headlights ?

 

Thank you! PhotoSync does reduce glare for night time driving. I would recommend contacting the manufacturer directly:

PhotoSync? - Prestige Film Technologies

 

How much do you guys typically charge to tint all the windows for a mid-sized car?

 

Here's what PhotoSync45 (45% VLT shade) look from a distance. To compliment its high heat rejection, it also looks quite nice to boot! For those wondering, PhotoSync comes in the following shades (for comparison purposes, OEM glass comes in at 85%-88%):

75%, 65%, 45%

Manufacturer mentioned to us earlier this month that they may be coming out with a 30% some time later this year.

 

Here is how this looks from the interior. Again, this is PhotoSync45 on the front two windows only. This product not only performs exceptionally well, but also has a high clarity adhesive system

 

The performance difference between PhotoSync45 (45% shade) vs. Porsche Thermal IR Glass in the rear windows (approximately 30% shade) is quite significant. Below is a simplified version of our test results:

At around the 2 minute mark - PhotoSync45 windows show a 2.2 degree improvement
At 2.35 minute marker, the windshield (no film) dash area registers a surface temperature of 101 degrees

The seats after over 18 minutes of exposure shows that PhotoSync45 registers an improvement of 5.1 degrees
The windshield dash at that time shows a surface temperature of 106 degrees.

Result: Although the exterior temperature does not provide a very compelling difference (it was only 72 degrees), there is an apparent variance between Porsche's IR Thermal Glass and PhotoSync45. Keep in mind the Porsche glass is darker, so less light (approximately 15% less) is entering the cabin in the rear, yet PhotoSync still outperforms it.

 

Not quite as dark as the factory glass shade in the rear, but close

 

Don't forget. the factory installed option by Porsche - "Thermal IR Glass" for the Panamera and Cayenne's cost $1125 for just the rear windows!

Yet, it does not perform as well as PhotoSync on a relatively cool day at 72 degrees...now imagine if it was hotter. The degree spread would be more significant!
