Series 700 Double Hung Windows

Series 700 double hung windows are a winning combination of classic design, superior materials and energy-saving technology — from a proven industry leader.

At the heart of each Series 700 Double Hung Window is our special polymer thermal barrier. This special barrier separates the interior and exterior of the window throughout the entire frame and sash, dramatically reducing heat loss in the winter and heat gain in the summer.

Standard Features

In addition to the features shown in the cutaway view, the Series 700 Double Hung includes:

  • Center cam locks plus hidden metal security locks on each sash
  • Carbon steel spiral sash balances
  • Each sash easily and conveniently tilts inward for cleaning
  • Full-length removable insect screens (half-screens available as an option)
  • Screen mesh in your choice of wire or fiberglass
  • Lifetime Limited Warranty when we install in your primary residence

Color Options

Our Thermal Barrier aluminum windows and sliding glass doors feature a durable, maintenance-free powder coat finish in your choice of five Standard colors. Designer colors and anodized finishes are available for an additional charge.
