SIW Impact Single Hung Windows


All of SIW’s windows are fabricated with heavy .078 to 1.25 thick aluminum frame (not PVC), and laminated glass. SIW windows’ low tolerance reduces air-infiltration, therefore reducing heat transfer between the inside and the outside. Low-E glass and insulated glass options are available for areas experiencing a high level of sunlight. 


  • Maximum size tested: 53 ⅛” x 96” with (+106.7 -130)
  • Heavy-duty extruded aluminum is painted with an electrostatic paint for low maintenance
  • Frame depth is 3″ for windows
  • Nominal wall thickness is .078 for all windows
