The double hung Irwin Window incorporates the award winning Parallex Hardware allowing the window to open and close in ONE step. The sashes slide and tilt, and securely lock into place with the user friendly Multi Point Lock system.

The Slide 'N' Hide Screen enables you to slide the screen into position only when you need it. The patented design cleverly integrates the screen mesh and hardware into the window so that it doesn't interfere with the good looks or operating abilties of the window.
