  1. I suggest looking at the published IR numbers. What most do not understand is that IR from 750 to 2500 nanometers is part of the TSER values. Why? because this near infrared is part of the solar energy. There is infrared from 2500-5000nm commonly called far infrared and this is more akin to the heat off the pavement or re-radiated heat which as opposed to the solar or a more compressed (shot from a gun) wavelength has less heat energy but is straight up hard to escape even in the shade. Further, the glass in the car only transmits 20-40% of the near ir. It has mass and a molecular matrix only some of the wave can corkscrew through. The IR absorbing property percentages are less meaningful as a solar filter as a result, because who gives a shit if you are stopping 99 or 97 or 95% of 40 or even 20% transmission. Functionally they are too close to feel a difference. However, this is not the case for dropping the standing temp inside a car where only IR is trying to leave the automotive greenhouse and 11heat is reflected back inside by the glass. The glass bonded high ir film is the superior method of holding heat to the glass and thus emitting it to the exterior via high emission glass values and convection as a radiator has such a valued effect.
  2. R value is the U value of a material divided into 1 as a standard so that commonality can be found across dissimilar materials. U value is a percentage because flow rate of energy is important but actual degree measures are not useful. A brick has an R value of 4. Why? Because 1/.25=4. The U value of a brick is 25%. that means 4 degrees go in one side and 1 comes out the far side. Or 40 go in and 10 come out or 100 go in and 25 come out. U values on products like Enerlogic are given around .62 these days. 1/.62=?. So in the overall measurement of the R value of a window of course the frame comes into play. The frame is roughly 25% issue, made problematic by the reality that the more solid a material is then also the better it conducts and holds energy due to its mass. If you did the little math I left for you then you should also know that R values of materials are sums. They add together like you wearing multiple shirts.
  3. @Bham, Yes it is a different way of considering an installation. Perhaps necessary, because the Stratos itself has a lot of parts and the factory still pretty tight lipped about the core details. Of course it is better to simplify when possible, but in the absence of manufacturer supplied details, field observations are certainly valid, and they also tend to make all of those hard to corner variables into one lump. This allows me to learn some things sure, but no real details. I suspect, as much as anything, the sheer thickness has effected the U factor. I was told it has 2 layers of TiN from the Pinnacle line. I think this also impacts the glare, because there is not as much angled light for sure. It has a deeply clear look from inside. Where is your shop anyway? I went to school in Bham.
  4. So tser is a measure of heat reflected and heat absorbed. What is the measure of heat flow out of the vehicle? Emissivity? I took off Spectra photosync 45 and put Stratos 35 on my truck. Spectra 45 had a tser around 70, the stratos 60. While I detect the difference with the sun coming through the glass, the Stratos overall heat loss is markedly better while driving. It is like someone spraying water on the outside of the glass. Its not as hot as the spectra to touch, so its obviously losing the heat to the airstream better than what I had before. An improved greenhouse control film would be what I would call Stratos. I guess they are playing the fact that only certain windows can be in the sun at any moment, and the majority of the glasses are then just there to act as a radiator to lose overall cabin heat. Emissions is all I can really call it right now. Stratos is an emittin m*********er. Tser does not describe this at all.
  5. Most customers that come into the shop dont know about silicone or plastic polish. Its used to prevent oxidation over the years actually, but it is a lubricant to a degree as well. The high quality grades won't smear and usually advertise that they are good for hard shiny surfaces or glazing. The best ones are a better replacement for a car detail spray.
  6. Factory laminated glass that has oem solar coatings require a certain edge border to remain sealed and not have the fancy coating fail due to corrosion. The factory edges I have been measuring on the Mercedes line have been 3/8". The tight tint edges looks better to me though.
  7. I didnt like mine. I gave it to a library. The Roland cx400 that replaced it was a world apart.
