ᐅ Windows in New Construction: Triple Glazing with a Green Tint?

Hello dear forum members,

I have a question for all home builders!
We have had our windows installed for a few days now and were quite excited. Unfortunately, we are a bit disappointed because the window panes have a noticeable green tint. We never discussed the glass with the window installer, as it never occurred to us that window glass might not be completely clear.
Apparently, we received some kind of "insulated glass" with a coating. We really don’t like the green tint; it makes everything look dull and even makes us look a bit "sick" ourselves... :-( It feels like we have the glass from a light sunglasses lens as a window, instead of “real” windows!

How is it with your windows?
Is it normal for triple glazing to have some kind of color tint?

Do you think it only bothers us now and that once the interior is painted white, it won’t be so noticeable anymore?

Many sunny greetings!

The "green" really only stands out when the sun is shining and you hold something white in front of the windows.

I've never held a white sheet of paper in front of the window.
Unless your neighbor has a smooth white wall or garage right in front of your window, you won’t see it like that again.

It's like when a ceiling is painted perfectly evenly. You notice it right after painting, feel a bit annoyed, but after a few weeks no one pays attention anymore.

As expected. The glass is state-of-the-art, high-performance insulating glass, with double coatings on both the inner and outer panes. This keeps the cold inside the house and blocks the sun’s heat outside.
The window manufacturer also says that since we ordered the windows with this U-value, that’s how the windows are supposed to be.
In the end, we would be stuck with the costs if we insisted on different glass. My husband thinks so, because he says good glass and natural light are quality-of-life features that last forever, but I’m not so sure anymore. Everything has its pros and cons.

Well... for now we’ll wait until everything is plastered and painted. But the difference compared to double glazing is really noticeable. Yesterday my husband removed a basement window and held it up right next to the triple-glazed one...

What sort of “g-value” and light transmission do you have?

Ours has a Ug-value of 0.5 and a g-value of 35%, light transmission of 55%.

Honestly, if you order glazing that only lets through about half the sunlight, don’t be surprised if you end up in a pretty dark space.

The green tint comes from the coating. It contains iron oxide.
The more iron oxide, the stronger the green tint.
Clear glass has low iron oxide content and therefore no green tint.
For regular glass, the intensity of the green tint depends on the total thickness of the glass (the thicker, the more green tint) and the strength of the thermal insulation coating (the more coating = iron oxide, the stronger the green tint).

I would strongly advise against ordering this kind of rubbish.

I can only advise everyone against ordering such rubbish.
You’re no better either; the post is 4 years old.

Thanks anyway for digging that up. I learned something from it.
