Viwinco S-Series New Construction Windows
Sleek, elegant and bold are three things that come to mind when discussing Viwinco S-Series new construction windows. Custom-made to fit any application, our S-Series windows are engineered using premium materials resulting in exceptional thermal performance and a contemporary look.




Key Features
- 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)

Window Types
Single Hung Windows
The bottom sash is operable and the top sash is fixed. Just raise the bottom sash for the ventilation you desire.
Single-hungs are economical, easily serviceable, and allow for trouble-free access to dry wall materials during construction.
They also provide exceptional energy efficiency.
Double Hung Windows
Both the top and bottom sashes are operable: the bottom lifts up, the top pulls down.
Double-Hungs offer beautiful sight lines and great air circulation.
Awning Windows
Awning windows share some of the same features as casement windows, such as the curved folding handle which you turn to operate the window, and the option to combine units to create an expansive window wall in a main frame. Hinged at the top, awning windows open outward. They look great topped by a fixed transom. Awning windows are available with all our color and other options.
Casement Windows
Casement windows provide beautiful views and smooth operation. Use as the only window style in your home–or to complement other styles.
Hinged at the left or the right depending on your preference, they swing open to the outside with a simple turn of the handle. Since they seal tightly when closed, they’re highly energy efficient. Multiple casements may be combined in a master frame to create a window wall. Our structurally reinforced window wall mull maximizes visible glass between sashes for a wider viewing area and abundant light.
We also offer a Colonial Casement. Designed to look like a double-hung window, it has the egress features of a casement window.
Non-operable Casement Picture windows are available, too. Casement windows are available with all our color options.
Sliding Window
With their contemporary, clean design and wide viewing area, sliding windows create a sense of spaciousness in a room.
Since the sashes slide open horizontally with no lifting force required, they’re particularly convenient for hard-to-reach areas, such as above the sink or tub.
