Double-Hung windows work well in almost any Nashville home and add energy efficiency, beauty and durability.

Double-hung windows are different than single-hung windows in that they have two window sashes that both open for different ventilation options, and offer simple ease of use.

Main Features of Double Hung Windows:

  • Heavy walled PVC framing acts as a natural insulator
  • Closed cell compression seal at sloped sill resists air and water penetration
  • Fin-Seal weather stripping at sill further reduces air infiltration
  • 3/4″ Insulating glass provides optimum energy efficiency
  • Dual hollows at lift rail add strength and insulation
  • Innovative® high-performance glass utilizes Low E coating specifically engineered for local requirements
  • “Warm edge” low conductance spacer resists energy flow through the edge of glass
  • Rigid leg on sill prevents “screen rattle” even on windy days
  • Coil Constant Force System is the strongest, most durable and never needs adjusting.
  • Insulation Filled Frames – insulated from the inside out
