Have just about narrowed choices for single hung vinyl replacement windows. Choices are Certainteed Somerton II, BMC West Performa 800 Efficiency, Pella ThermaStar, Pella Impervia, & ComfortWorld.
I realize that installation is most critical part of entire project. Plan on seeing installed products to judge quallity of install work. Anyone out there with experience pro/con with any of these brands? Any & all information greatly appreciated.
