S-Series is Viwinco's premier new construction line. Single- or double-hung units come standard with:

• Superior Insulating Value: standard high-performance glass package features 15/16" double-strength insulated glass unit with low-e, 
Interecept® ULTRA stainless-steel low-conductance spacer, and argon gas fill
• Robust, fusion-welded (as opposed to mechanically joined) frame and sashes provides superior strength and a permanent seal against water and air infiltration
• Multi-chambered profile provides top insulating value by trapping dead air, adding to the window's energy efficiency
• Sash interlock on double-hungs hooks the sashes to each other and to the frame, creating a tight barrier against air, wind and rain
• 5-degree true sloped sill directs water, dirt and debris away from the window and prevents it from collecting in the sill
• Tilt-n-Lock patented technology on hung windows reinforces and adds strength to the meeting rail for structural performance, and makes cleaning easy: open, close and tilt the window in with one hand
• Mortised-in, replaceable 1-3/8" high weatherstripped sill dam fights drafts and water infiltration
• 3/4" stainless-steel constant force balance system never needs adjustment and allows for smooth sash travel, and open sashes that stay in place
• Beveled exterior for traditional craftsmanship appearance
• Integral J-channel with 1-1/4" nailing fin for ease of installation
• Industry-leading DP ratings ranging from DP50 to DP70 depending on style—an air, water and structural designation by the American Architectural Manufacturers Association (AAMA)
