400 SERIES CONVERSION KITS FOR NARROLINE® WINDOWS
Narroline® double-hung window conversion kits offer a smart solution for upgrading Andersen windows manufactured between 1968 and 2013. These kits transform your existing units into modern tilt-wash double-hung windows with High-Performance Low-E4® glass — all without removing the frame or modifying interior trim.
As a Premier Certified Contractor for Andersen, ARDMOR Windows & Doors is trusted to deliver expert installation that aligns with the manufacturer’s specifications. This certification confirms our deep knowledge of Andersen products and ensures that every conversion is completed with precision, reliability, and long-term performance.
KEY BENEFITS
Improved Energy Efficiency
Each conversion kit includes High-Performance Low-E4® glass, which offers up to 45% better energy efficiency in winter and 56% in summer compared to standard dual-pane glass.* This upgrade helps reduce heating and cooling costs year-round.
Convenient Tilt-Wash Design
The tilt-wash feature makes routine cleaning easy by allowing access to both sides of the glass from inside your home—no ladders or exterior access required.
Customizable Style
Enhance your window’s appearance with optional upgrades such as decorative hardware, grille patterns, exterior trim, or specialty glass including art and patterned styles.
Hassle-Free Installation
Designed to fit your existing opening, each kit includes new upper and lower sash, balancers, jamb liners, and hardware—no need to alter the window frame or interior trim. This means faster installation with minimal disruption to your home.
HOW TO KNOW IF YOU HAVE A NARROLINE WINDOW?
If your windows have these four features, they’re compatible with the 400 Series tilt-wash conversion kit.
