When it comes to your home, energy-efficient windows require less energy to heat your space than traditional products. That means savings on your monthly bills and comfort year-round.
Double-hung windows allow both sashes in the window frame to open and close. This means that both the top and bottom panes of the window move up and down.
Window World Double-Hung Replacement Windows are ENERGY STAR-certified and manufactured with insulated glass and frames for superior energy efficiency.
At Window World, we design each of our windows to fit your home’s measurements. Contact us to learn size specifications on our different models.
Yes! When extreme wind and weather hit, you can be sure our proprietary sill interlock will stand strong. Traditional slope sill designs can allow the sash to bow during powerful winds, but thanks to our interlocking sash-to-sill technology, the sash is channeled firmly into the window frame for a unified wall of strength.
