Double Hung

Double Hung Windows


On our Double Hung Windows both the upper and lower sash slide up and down. Additionally, both upper and lower sashes will fold in to allow cleaning from the inside of your home. Our Double Hung Windows come standard with full screens.
We manufacture Double Hungs in:

  • High Perfomance Vinyl
  • Hybrid Aluminum (Thermally Broken)
  • Wood-Vinyl
  • FiberGlass

All frame systems available with a wide variety of glass packages to meet your design and energy requirements.


Hybrid Aluminum windows have a built-in structural barrier that dramatically reduces the transfer of heat and cold. Our Vinyl and FiberGlass window frames are natural insulators. All four of our window systems have deep pile fin-seal weather-stripping and are fully interlocking to reduce wind and water infiltration. Our insulated glass is engineered to provide  efficiency and energy conservation using SuperSpacer, SoftCoat LowE and Argon plus it’s backed by a limited lifetime warranty. (see actual warranty for details)
