Hello:

Regarding the Low-e (low emissivity) coating option that Anersen and Pella
both apparently offer on their lines
of replacement glass windows:

Do these coatings change the clarity of the glass ?

Still "crystal-clear" with the coating applied ?

Any discernable tint, or glass color changes, apparent at all ?

etc. ?

Unfortunately, none of the sample windows we were able to look at in the
stores
had the coatings; hence the question.

Thanks,
Bob
