Disadvantages compared to other system types:

  1. Window walls are usually mounted on top of the slab, and as such, allows for less tolerance in the concrete.
  2. Exterior access is required for installation of slab edge insulation and metal covers increasing the amount of field labor required and logistics of the installation.
  3. Head and sill tracks are the most critical components that are prone to leaks. These components are installed and sealed in the field that can lead to workmanship errors.
  4. Very few systems that can meet the stringent air infiltration requirements of the code which affects competitive procurement.
  5. Difficult to achieve thermal and condensation performance of the project using off-the-shelf systems window wall systems.
  6. Customizing and using a new extruded system increases cost reducing the cost-benefit of these systems.




Disadvantages compared to other system types:

  1. Unitized systems have no discernible disadvantages to other system types when considered for use in a high rise tower.
  2. Although initial cost may appear higher the cost of unitized systems, it is offset by GC/CM fees, general conditions, and better schedule when compared to window wall or stick built systems.
