![]() ![]() The United States lets manufacturers get away with only 70%. Pure powder is the strongest vinyl available on the market but is expensive. The reason isnt to make it stronger it is to save MONEY. This is what Milgard claims their formula will do, fade evenly, no streaking or uneven color. (thats why only a few use pure)Īs far as fading goes, it depends on what kind of inhibitors they use and how much, its the INHIBITOR which prevents the fading,īut all vinyl, fiberglass, aluminum and wood WILL FADE, the thing you want is for it to FADE EVENLY. Most companies believe a mixture of vinyl is better than pure for strength. After that, additional processing "uses up" some of the lubricants and other additives that are used in the extrusion process. As a thermo plastic, PVC can be reprocessed, typically, around three times with little degradation to the compound. The implication is that "virgin vinyl" is purer or superior to reground vinyl. Regrind is the term given to vinyl that has been extruded, then the parts are ground up into small "pellets" and can be re-extruded. Virgin vinyl is the term applied to vinyl that is extruded for the first time. So the comment is not about the entire PVC material being 100% virgin vinyl, just the pure vinyl ingredient used is 100% as opposed to a combination of different vinyl ingredients. I think that's what Bryan is talking about. Correct me if I'm wrong, but the vinyl powder itself has the % of virginity, although it needs to be mixed in with other additives to reach PVC state. Maybe he just didn't want to agree? =) Or maybe he's taking the technicality in another direction. he has nothing to gain so i don't know why he would lie. i was talking to a customer the other day that is chemical engineer and he told me that it is impossible to have 100% virgin vinyl. and of course they just happen to be the brands you sell. there are over 300 window manufacturers in the us and according to your statistics there are only three that use 100% virgin vinyl.

He got his windows re-done, and one of them had a latch that malfunctioned so I told him to call the company he bought from. ![]() My dad is notorious about that kind of thing. I think they gamble that a lot of people will not notice, and out of others that notice, not a lot will really care about making a big deal about it. I think it's a major scam, and I'll wave the conspiracy theory flag for a bit here, but it's something you have to think about from an economics level: How much more expensive would it be for milgard to produce a 100% color retaining vinyl window, vs, How much is spent on how many people actually notice their windows turn yellow over time and put in a replacement request. ![]() Supposedly (and I say this with extreme reluctance), milgard windows *might* turn yellow over time, at which point "what do you care, they have a warranty" was his sentiment. This is what our Milgard rep told us about the yellow vinyl thing. Coming from a background in design and color theory, I bet a large amount of people will never realize their windows have yellowed unless they put a sheet of white paper up to the window. ![]()
