WindowWall systems save you time and money!


Advantages of a Unitized WindowWall System:

  • Higher performance
  • Reduced installation time
  • Lower field labor cost
  • More per-job customization
  • Tighter Quality Control

Custom Window Company offers a variety of frame depths and profiles to meet your needs in high rise construction. In addition, we will happily modify any system (or create a completely new one) to satisfy the aesthetic or performance requirements of the project.


Standard frame depths are from 3 1/4” to 6”, with custom depths available, and come with a wide variety of mullions, receptors, sill channels and slab edge covers.


WindowWall Systems:

  • Available in fixed, project-in, project-out or casement configurations
  • Some systems accommodate zero sightline ventilators
  • All systems are thermally broken
  • Available in the full range of Kynar colors or anodized finishes


All unitized WindowWall systems from Custom Window Company are tested to the highest performance standards.


Each system has been AAMA tested to meet the requirements for an AW (Architectural Window) rating. All WindowWall systems have been tested to a minimum rating of AW-60, with air infiltration less than .1 cfm and water resistance to 12 psf.

WindowWall systems significantly reduce field installation time and labor.



Windows are pre-assembled into side-stacking modules. Fabrication work ordinarily performed in the field is instead done in the factory, concurrent with window manufacturing. The result is reduced field installation labor, saving you TIME and MONEY


Unitized WindowWall systems are assembled in a factory setting where rigid quality control measures are enforced. This ensures that all of the joints have been properly sealed, weatherstrips properly installed and glazing has been done to strict standards. Ventilators are factory installed and sealed, again reducing the risk of water problems in the field.


Hinges, handles, sealants, glazing materials, aluminum and glass are all the highest quality available in America.



Inswing, outswing and sliding terrace doors are available to complete the package.
