Silver Line's® new Series 400 Poured Basement Window Systems offers an innovative design solution with timesaving, pinpoint accuracy for basement windows, that virtually eliminates the possibility of distortion. In addition to traditional poured concrete foundations, the system can be used with Insulated Concrete Forms (ICFs).

The Series 400 is a two-piece basement window system featuring a wood reinforced, vinyl Poured Insert Frame and the option of a Hopper or Sliding Window. The wood reinforced insert frame maintains its integrity during the pour for better accuracy. The patent-pending injection molded Hopper and Sliding Window units are air- and water-tight, providing protection from the elements. These strong, seamless, cost-effective basement windows never need painting for easy maintenance. The poured insert frame and window are shipped separately, so the windows can be conveniently stored away until the foundation and

framing construction are complete.

Once the foundation has dried, the wood reinforcements are removed and the windows can be neatly and accurately inserted into the frame. A snap-in retaining bead secures the window in place, with installation completed in just minutes!
