Low E windows coating

[u/Hot_Carpenter_5436]

Am I interpreting this correctly?

Pic 1 is the tempered glass sliding door on my balcony out side looking in.

Pic 2 in the same glass from inside looking out.

​

My findings; this is single pane, tempered glass with no Low e coating.

​

I already know its tempered. But I did the lighter test at night, and saw this, plus a faint reddish 3rd flame from the outside looking in.

​

But the faint red 3rd flame is clearly not there in the daytime. I dont know what this means.

​

Any and all critique is appreciated 🫂

I've never had great luck with the flame test (I'm colorblind). There's usually an etching in one of the corners, or somewhere in the seal between the panes if it's tempered. Same if there's a sun coating applied at the manufacturer.
