Fusion Welded Frame & Sash
Welding creates a fully sealed, continuous profile that eliminates potential air and water penetration through frame and sash corners.
Maintenance Free Solid uPVC Vinyl Profiles
The multi-chambered design provides structural strength as well as insulating air pockets which reduce heat and cold transfer
Built in water drainage design removes water from the hidden sill pocket.
Integral Lift Rail
Permits single sash to be operated with ease.
Integral J Fin
Ideal for siding applications, offering cleaner details and improved performance (201SJ only).
Double Bond Glazing System
Flexible dual durometer seals hug the glass from both sides. The system also includes a glazing tape applied to the interior side. The result is an unprecedented barrier against air and water penetration.
Commercial Glazing Technique
Exterior glass stops, combined with the Double Bond Glazing, are more effective in maintaining a well-sealed window.
