My new home is a 1920 one and a half story that was completely rebuilt with brand new everything in 2008, with the exception of the wall studs, the rafters and the basement. Throughout my house, the contractor installed Viwinco Signature Series Double-Hung Vinyl Windows. The double-paned windows are 15/16" thick glass. The space between the glass panes is weatherstripped and filled with argon gas for energy efficiency, so I don't have condensation build-up in my windows, even after a hot shower or on a cold winter's day, and that's guaranteed for a lifetime. The Viwinco Signature series vinyl windows are Energy Star rated for thermal efficiency, and they qualify for the energy tax credit.
As vinyl windows, they only come in white or tan, and it's impossible to paint vinyl a different color. On the other hand, the Viwinco Signature Double-Hung Vinyl Windows are very easy to clean, and they come with a Lifetime limited window warranty. And the sash can be locked for added security. The Low-E glazing on the glass provides UV protection, so I don't have the problem with sunshine making bleach stains on my furniture anymore. Viwinco Signature Series Double-Hung Vinyl Windows offer a lot of bang for the buck compared to other vinyl windows.
