I think this is a good deal and I will likely get one. Thanks!

@EVinsulate is now officially selling its EVglass solution for the Mach-E. Head on over to evinsulate.com to order yours.

Big thanks to @Mach-Lee for proving the benefits of creating a thermal break for the panoroof to reduce cold weather heat loss/convection cooling of the cabin here: https://www.macheforum.com/site/thr...ing-taking-requests.24393/page-10#post-595252

@EVinsulate created the EVglass kit for the Mach-E working with owners in Ontario here: https://www.macheforum.com/site/thr...-work-with-evinsulate-for-a-mach-e-kit.33596/

I and a few other members so far have purchased and installed the EVglass kit on our Mach-Es and so far the results are fantastic. It maintains the factory look and feel of the cabin while dramatically reducing the draft you feel off the panoroof in the winter and at highway speeds. The kit was fantastic, well thought out, and very well made. Follow the instructions fully and take your time with prep and install is a snap. I give it 5 stars.

Ok, I hate to be a skeptic here, but could someone please explain to me, in bunny rabbit English, exactly how you would feel a draft through a solid piece of glass?
Im sorry, but this just feels scammy, like the outfit on the home page trying to sell rear view mirrors for the Mustang Mach-E that enhance your rear view - apparently, they never got the memo about BLIS. ?‍?

The interior glass feeling colder (which it absolutely does, as I learned last Winter and this Winter driving thru Wisconsin, Minnesota, Colorado, Maine etc.) chills the cabin air, which in turn creates convection currents up & down across the cabin which chill said cabin air even further. Those cold convection air currents might feel like a slight draft as they waft across our exposed skin areas.

it is not a draft thru the roof glass... it is a convection "draft" inside the cabin air which is started and then reinforced through the coldness of the large cold surface of the roof glass. A result of one of the several Boyle's Laws on gases, and all that.

That's my story and I'm stickin' to it...

I had someone try this on their Model Y and it worked, so probably also on the Mach-e?
I'll update when I get it installed.

Much like the way I feel hot waves of air from the dashboard and roof. It's hottest if you touch it, but it heats about 1 to 2 inches from the glass, the ac blows that air around (or the heater) to it's waves of hotter or colder air. I waffled for hours on this. I figure it's really a much better looking version of the $50 sunshade thing I have.

I'll likely throw out my now slightly ratty aftermarket pano reflector / cover which I use in Summer and in Winter with an added solar reflector layer, when I install my double pane shield. Then I will hopefully be done with seasonally messin' with the pano roof.

Thank you! And your bunny rabbit English is perfect! ? I withdraw my earlier criticism. I don’t live in a super-cold climate, so I’ve never noticed any drafts. We do have hot summers and the cabin is always noticeably cooler than the cabin on my escape was.

Does condensation form since this is room air that is trapped between the glass layers? Like when double pane house windows lose their seal and get fog and condensation between the glass layers?

No I haven't seen any condensation. The only thing I have seen is slight haze frost form on the panoroof glass when it's extremely cold and at highway speeds. when it warms up or the sun hits it that goes away again.

I totally get what you're saying and I was curious about that too after I installed the EVglass. But I have to say it stays remarkably clean and clear considering it isn't perfectly vacuum sealed like a manufactured double pane window.

We'll see if the AZ sun kills it within a year like it loves to do to most any other poly. I assume the MME's IRR roof should help, if not stop that from happening.

When it’s really cold, range will be the same, you’ll just be warmer (heater is already maxed out).

When it’s warmer it will probably only save a couple hundred watts of heat. If I do the math, it’s only to be about 1-2% improvement in range. So not enough to notice. Day to day variability is much greater than that for me.

So buy it for comfort, not for range.
Thanks for this. Sounds like a good product, but not something I’ll need in Virginia.

The roof blocks a lot of the solar radiation but it isn't IRR. You're in AZ so why are you buying it again? I'd be concerned about trapping too much heat under the glass and causing it to shatter from thermal stress. This is primarily a cold weather climate product.

In my Reflextix article I have a warning against leaving it in during the summer, since the excess heat could crack the glass.

In a hot climate a cloth shade would be the best option.

You wouldn't happen to know what the relative humidity was when you installed it, would you? I'm guessing Manitoba may be pretty dry, especially if it was installed in the winter...?

Yes our winters are fairly dry here and it was I think -10c outside when I installed it (right before a cold snap to below -20c) so it would have been pretty dry outside.

I installed it in my garage though, which is temperature and humidity controlled year round. Temperature in the garage was 19c and the humidity in the garage was 30-32%.

Thanks! That's very useful information. I doubt I'll get one unless I go on a winter road trip, but the humidity here in San Francisco is almost always well over 50% (currently 86%), so it's a factor.

Does it keep heat out in the summer?
The heat doesn't come in during the summer, as attested to by many owners in AZ and other places.
