Vinyl Window Basics
There are literally hundreds of vinyl window manufacturers in this country. The majority are regional producers that put out a mid grade window with mediocre to decent performance numbers. While there is nothing wrong with these windows per se, they are not going to be your best bet in terms of long term value. Nearly all manufacturers purchase the actual vinyl extrusions from one of the handful of vinyl extruders across the nation. They will also buy the glass panes, spacers, hardware etc. and then put it all together at the factory. What most consumers don't know is that there are a ton of ways to cut corners in the process of making a vinyl window, the majority of which are very difficult to see with the unpracticed eye (imagine looking at two car engines side by side and having to say which was the superior engine).
