All Interstate double hung windows are built with the Light-Lift Window Sash Balance System for maximum ease of use when opening either sash. Unlike weighted sashes, Light-Lift ensures consistent, easy-to-manage tension whether opening or closing.
• Minimal effort required to operate windows making Interstate windows much easier to open and close.

• No tools are ever required, Light Lift™ is factory set and installed.

• Adjustment is never required. Our balance is tested to over 4,000 cycles.

• Fully warranted. We will replace any Light Lift™ balance that fails for as long as you own your home.

• Specially designed air block prevents the “chimney effect” of air blowing up side jambs and into house, saving fuel, money and eliminating annoying drafts.

• The Light Lift™ balance’s design allows for maximum ventilation and egress.

“You’ve Got to Lift
It to Believe It!”
