Some years ago, The Home Depot began selling Pella's ThermaStar line of vinyl replacement windows. But even then, I was not very hopeful because the offering was extremely limited (mainly double-hung, casements, and fixed windows). Not only that, but there were not many sizes to choose from.
Eventually, Pella switched over to Lowe's. ThermaStar still didn't take off right away. But lately I have noticed Lowe's devoting more and more shelf space to the ThermaStar line.
A "Basic" Window - No Frills
Now, don't get me wrong. ThermaStar is still exclusively vinyl. And best as I can tell, ThermaStar is a pretty "basic" window, if you get my drift. There is nothing fancy; this is very much a stock, grab-it-off-the-shelf product.In 2007, Consumer Reports rated ThermaStar 25 Series windows #16 on a list of the best replacement windows in the U.S. If you think #16 sounds low, keep in mind that the last time I checked, there were about 200-250 window manufacturers in the U.S.
Vinyl Windows - Basic Shapes
Shapes and styles now include bows, bay, and sliders, as well as what Pella calls "special shapes." Sizing runs in 1/8" increments.Good Way to Try DIY Window Replacement
If you're interested in trying out your hand at replacing windows yourself, you might want to pick up a ThermaStar and try it in an out of the way location. Also, give yourself plenty of lead-time because I really can't imagine that they have all shapes and all sizes right there in stock.So, things are looking promising in the DIY window replacement world.
