The Benefits of Our Single-Hung Windows

When you choose Siding Unlimited to be your replacement window contractor, you’ll receive single-hung windows that are:

Energy Efficient

Single-hung windows only move in one direction—vertically from the bottom sash—leaving less room for air infiltration thus reducing thermal transfer. Additionally, our windows come with features like advanced low-E insulating glass to further boost their thermal performance.


Our replacement windows are available in a wide selection of shapes, sizes, and finishes to create a look that complements the style of your home.


We offer single-hung windows in your choice of the following hard-wearing materials:

  • Vinyl
  • Fiberglass
  • Aluminum-clad
  • Wood
