Heat & Noise Insulating Glass - Noise?

Hi All,


I am one decision away on finalising my GTS build. I contacted my sales rep about this option and he said it gave the glass a purple haze. He did not say whether the haze looked classy or horrible?


I also would like to know how much of the engine noise is blocked out and whether simpy opening the pano roof provides a soundtrack. I am largely considering the option for heat protection as the cost of heated and cooled seats in Australia is very high.


I am also getting the Burmester.


Advice or comments greatfully received.


Paul

I have the insulated glass. Never noticed any haze, purple or otherwise. Of course, the rearward windows do have a darker tint, similar to the standard privacy glass.

I don't have a good basis for comparing the sound with and without the insulated glass. And I don't have a sunroof to test out that part of the question. I do feel like I can hear all I want to hear. I especially like the exhaust pop from the turbo dump on aggressive upshifts. Fun stuff!
I highly recommend the insulated glass option. It really helps keep the cabin comfortable. I'd definitely get it again.

I would say the same as SoCalS5 wrote. I'm a fan of it and ordered it again for my GTS.

The purple tint or haze can only be slightly recognised if you are at a certain angle to the glasses and/or you have polarised sun glasses. In daily life you wouldn't notice it and I can higly recommend it to you.

Notice on Burmester: I also wanted to have it, altough here in Switzerland it is horribly expensive, and after asking several Porsche specialists they all said to me: fantastic... take it if you really listen to classical music, which I do, "but" Bose will do a good job in 80% of the listening time. So I have ordered Bose.

Enjoy your almost new car!

You're ordering the Burmester in Aus ($12,300 for our offshore friends). and you're worried about the cost of cooled seats:confused:

Irrespective of whether you get the insulated glass, you should get the ventilated seats - you won't regret them, close to a must have.

My advise; forget the stereo, get the PSE (oops, forgot std on the GTS), wind the window down and just listen to that engine:)

I have the thermal glass and like it. I haven't noticed any unusual tint or anything. You can still hear the engine but it does seem to cut down the road noise. I haven't had my Turbo long enough to feel the impact of the summer sun but I hear it helps. I do have the heated and vented seats. In the middle of winter, the heated seats and steering wheel are used daily.

One thing I did find out what that it blocks RFID signals. The local car wash uses a RFID sticker for access and it won't read it through the thermal glass. I had to get an external one.

@PaulB , I forgot to mention that the insulated glass option supposedly reduces cell phone reception inside the Macan somewhat. I never use a cell phone anyway and I very seldom carry passengers so I can't give you any personal insight on that, but earlier postings on this forum and others suggest that you might lose one bar or so of strength in weak reception areas. Other members on this forum can chime in with their experience, but I don't think it's a significant issue for most people.

Thank you everyone for your advice.

I can't see me ever needing heated seats hence the choice of the insulating glass
to cool down the cabin in the summer months.

Have any members experienced poor reception through their mobile devices when in a car with the insulated glass?

The Bose vs Burmester choice is really hard and yes it is very expensive. But...with the kids at home, I mainly listen to music in the car and intend to keep it for five years plus so....I think I can justify it, maybe....

Really hard to know when to stop with these options!!!

1) No purple haze
2) No reduction of cell phone reception
3) Helps with cabin temperature if parked in the sun, but no substitute for ventilated seats
4) Cuts down on exterior noise, but especially on start up, you know that, and anyone within earshot knows that, you are driving something special.

I'd get it again, but it isn't my favorite option.......

Cell phone reception in car is the same as outside of the car. Drove it on a 3500 mile trip and both cell and data receptions were good where there was signal available. The dotted area to the left and right of the rear view mirror allows gps signals, radar detector and toll transponders to work. Haven't driven a car without so can't vouch for noise or heat reduction. I would order it again if getting another Macan.

Most of the heat ingress is via infra-red radiation on sunny days. I use my vented seats even in the winter here about 50% of the time and every time in the summer. I also run with my sunroof tipped up to get more exhaust music.

There are some really good tint films available now with nano-tech u might want to investigate, versus the glass option. They don't have to be dark tinted to block >98% of the heat rays. And of course white paint is the one to choose if u want to stay cooler inside. Studies have shown that white is the standout color for blocking radiated heat, and that other colors are more like black when it comes to radiant heat absorption, altho bright yellow and silver aren't as bad.

BTW, in southern Louisiana Purple Haze is a beer. It's a raspberry wheat beer made by Abita Springs Brewing. I like most all the Abitas except that one. So I guess u could say I took don't like Purple Haze

The new nano tech films are as good as any glass and don't have to be dark to block UV and IR. But they might cost more than the $990 Porsche glass option. Im not sure and need to check and get mine done. The one film I looked at required me to drive 100 miles to Tampa to get it here in FL. I need to do something but like u, don't want super dark tint. It is probablecause to harass u in a number of states, esp the Chicago area where we are headed this Summer. I just want to keep the UV and IR out, not darken my windows.

Sounds like the factory installed thermal glass is the better option for you.

Any film applied to the outside of the glass can be damaged or otherwise peel. The polyvinyl butyral interlayer in the factory option is sandwiched between two sheets of tempered glass making it similar in construction to windshields. It's also something that may entice the future buyer of your car.

IMHO an aftermarket film is only appropriate if one wants additional tint or if one (understandably) balks at the high cost of thermal glass.

Or,,,, if one already owns one without that glass option. Or maybe they don't mind really dark tint which is fairly cheap. Truth is I had a lot of cars with tinted windows over the years and never had a problem from scratches or purple haze. But I do take good care of my cars, especially my Porsches. If someone has kids that r roughnecks, glass is certainly the only way to go.

I have the privacy glass and tuned the fronts to match the rears for cosmetic reasons only. It's a great option; cell reception is fine but you definitely need to put any transponders in the black area right around the mirror or they don't work at all. The glad is a little more hazy from the outside, providing a bit more privacy than a basic tint. Whatever they do is one -way though because I've never seen it look hazy from the inside.

The decrease in road noise is nice but the main benefit is the heat rejection and it's very effective. My car stays amazingly cool for black leather. Highly recommend.

I have this heat insulated glass on my GTS and notice a rainbow glare on my carbo fiber interior on a passenger side when I drove. Is that normal, would tinting the front windows hide this rainbow glare i see on the passenger side while driving? I don't see it in my driver side but when I looked to my right, I saw a rainbow color on my CF interior panel. In the shade, I don't see the rainbow reflection there.
