Pella,V Milgard, V Alpine
I am just about to replace 8 windows in my house her in Alaska and have gotten 3 quotes from 3 different companies each selling 3 different windows. All are sliders and comparably priced all seen to have all things in common. Can anybody let me know which is the better window between the 3. Thermastar by Pella, Milgard, or Alpine by Alside. Thanks Peter.
