I haven’t cleaned the windows yet, but the coating is facing the inside of the house so it if touched will leave the charcoal mark, or scratch mark.
I called jen weld and they said that they put the coating on both sides of the window now to meet “some code”?!
She said since it was on all 6 new windows there was nothing wrong, but if it had been 1 of the 6 then it would be a defective window.
So my question is: is she right or am I right?
I told the home owner that if the dog jumped on them or the accidentally hit it with a chair, or put tape on it, they would mark…
low e coatings are always placed “inside” the units. not the side you can touch.
“Coating a glass surface with a low-emittance material and facing that coating into the gap between the glass layers blocks a significant amount of this radiant heat transfer”
they must be the “exception” to the rest of the industry. there are many many types of low e coatings. sounds like they chose the cheapest one you can get and have to apply it wrong to get it to meet standards.
the only thing I can imagine is they put a tint film on the glass. the industry standard is to put low e coating on the #2 and #3 surfaces.
How can they have it on surface 1? The home owner isn’t happy with the windows due to the fact that in a few years they will have marks on them due to this coating
This is the same thing Pella is doing (as well as some other window manufacturers) to meet a new federal code. I have tried finding the specific code they are trying to meet but keep getting bounced to the older standards. I would think that these manufacturers would have a link on their sites to validate why they would put such a easily damaged coating on the interior of a home. I would tell the homeowner or builder that you have no way to remove anything other than simple dirt from these surfaces and if they get anything else on them they have destroyed the window and it will need replacement. If they have paint, silicone, etc on them I’d suggest to them they find a window manufacturer who can still get them a normal window before this stupid code goes into effect.
Umm…every time i have ran into it they fixed it because it was put together wrong…common sense tells me that the coating should go on the two interior side of the thermal pane window!
I’ve run into that in the past as well and it was definetly a manufacturing mistake. Now there is some new code that may or may not be going into effect soon, when you add politicians into anything you can throw common sense out the window.
there is a very very high possibility the guy/girl working at the factory is putting the glass together wrong. they are probably new, or just lost track of what they were doing.
[B]LMAO![[/B]QUOTE=hunterst;106298]So they put together six windows(or more) wrong and they all got through inspection? Then they all happened to be installed on one house?[/QUOTE]
have you ever been to a window manufacture? trust me, they hire high school drop outs. it’s very possible. they are usually paid min wage. these aren’t high skilled workers at most places.
Although I have seen this done as a mistake what Severn is dealing w/ (and what Jay is confirming) is that the manufacturer has done this on purpose to reach a new (unnecessary in my opinion) federal energy standard that may or may not be law in the near future. It’s intentional in this case.
Any WCR forum threads that i’ve come across have mentioned that they (the window cleaner) were informed by the client that the windows in question has low e on the out side sides of the glass. Is there a stamp or marking on the glass to warn window cleaners of this Low E on the outside surface?
Wouldn’t the glass industry kick up a fuss over any law/regulation forcing the low e to be on the outside of the glass, due to the greater likelihood that glass would get returned to them or taken to the dump because how easily it can get damaged?
