Why does this tint look different?

[Wyeao]

Hello

 

i recently had one of my glass panes in my window retinted as original glass was faulty. Glass was replaced then re tinted. Why is one green (newly tinted) and the others purplish?

Possibility the replacement glass was not correctly matched or the replacement film was not correctly matched:

 

~ If the original glass had a tint and the same exact film was used on the replacement, then the glass people got the replacement wrong.

 

~ If the original glass was clear and the replacement glass was clear, then the film people got it wrong.

-------------------------------------------------------------------

Another possibility would be the original film had a dyed layer to tone down/give it a smoke color and it has changed over time (Dyed film in residential is a rarity these days).

 

I'd put my bet on the former possibilities as opposed to the latter.

Thanks for the reply.

 

The glass definitely was clear, both old and new. The glass supplier mentioned low e glass. Maybe one is low e and one is not? It was a passing comment and I have no paper work indicating it’s low e glass. Is there anyway to tell if this is the problem with the colour?

The flame can be red-ish, blue-ish, green-ish depending upon the component producing the lowE performance value.

 

Keeping in mind, the applied film will impact this test, so attempt it from the outside.

 

The video talks of surface 1, 2, 3, and 4, so the applied film is on number 4. Best to do this on a cloudy day, too.

 

Standard lowE generally shows red-ish flame and hi-performance lowE is blue-ish or green-ish flame and is also  known as lowE2. You may also discover multiple colored flames respective to the surface it is on. This is indicative of having a lowE coating on 2 or more surfaces.

 

Standard lowE retains man-made heat to the interior space, whereby hi-performance lowE retains man-made heat to the interior as well as rejects the sun's solar energy away from reaching the interior.

 

A friend of mine has a sun room built out of lowE glass panel walls and roof with lowE4 capable of 90+% solar energy rejection (pricey stuff there).

To determine if there's a color problem you might have to remove the newly installed film and an older piece on the adjacent pane. At that point you are able to determine IF the two pieces of film are different and if the replaced glass is different from the older glass. It's def a pain in the azz, but one of two contractors has missed the mark.
