400 Series conversion kits for NARROLINE® WINDOWs

Narroline® double-hung window conversion kits are designed specifically to retrofit existing Narroline® windows (made from 1968 to 2013), turning them into easy-to-clean tilt-wash double-hung windows with High-Performance Low-E4® glass.  They’re quick and easy to install with no window frame tear-out or trim modifications.

  

 
Increased Energy Efficiency
High-Performance Low-E4 glass® comes standard and is 45% more energy efficient than ordinary dual-pane glass in winter and 56% more energy efficient in summer*, helping to reduce heating and cooling bills.
Easy Clean Tilt Feature
The tilt-wash feature allows you to conveniently clean both sides of the glass from inside your home.
Style Options
Add style with upgraded hardware options, grilles, exterior trim, art glass or patterned glass. 
Easy to Install
The installation process is simple as your existing frame and trim are unaffected, so there’s minimal disruption to the home. Kit components are sized to fit your opening and include new upper and lower sash, balancers, jamb liners and hardware.
