More Light, More Space, More Beauty
Bay windows are built from three window panels, often including a fixed center window with casement or double-hung flankers. The angled configuration creates a natural nook inside — ideal for seating, shelving, or just letting light pour in.
Made by OKNA – Engineered for Year-Round Efficiency
OKNA’s bay windows are built with multi-chambered uPVC frames, high-performance insulated glass, and airtight joining systems. These units are beautiful and durable, with interior seatboards available in woodgrain or stainable finishes.
Add Value and Curb Appeal to Your Home
The outward projection of a bay window enhances both the interior experience and your home’s exterior architecture. It creates visual interest, adds dimension, and brings a sense of luxury to any room it touches.

Bay windows are three sided windows that project outside the house. They consist of one central window that is parallel to the walls, and two angled windows that come off the side of the front window. Since the windows are set outward from the face of the building, they add extra depth to the interior bay window area.
Benefits of Bay Windows
Change The Architectural Look of Your Home
Bay windows let you change the basic architectural look of your home – inside and out. They can open up any room and make it seem larger and brighter.
Beautify Your Home
Not only bay windows are designed for opening up rooms, they are also designed for beauty. They help create dramatic new appearances adding style to the exterior of your home as they expand interior space, light, view, and therefore the beauty of your home.
Add Value to Your Home
Bay windows are the perfect addition to any Connecticut home. They create an instant feeling of light and view while providing a beautiful focal point. Any custom addition, such as bay window, adds to the value of your property.
Connect With Natural Environment
Bay windows typically have a large fixed picture window in the middle that provides panoramic view of your outdoors. This expanded view can create an enhanced feeling of connection with your outside world. Also, a bay window can be a perfect spot to just sit and relax after a stressful day.
Create Additional Shelf Space
Expanded space of your room provides additional shelf space. This space can be used to grow your plants, flowers or vegetables. It can also be used to showcase your other things that are important to you, for example vases, photographs of your loved ones, collectibles, decorations and home accessories etc.
Add Light and Fresh Air
Because bay windows project outside the home, they will allow more light into it. Our bay windows have multiple-sealing, fully screened operating casement windows or double-hung windows that allow bringing in gentle breeze on the warm, sunny days.

Insulated Head and Seat Board
OKNA Bay and Bow Windows come in standard with ½ inch polystyrene insulation both in the seat board and the head board. Additionally, per homeowner’s request, we can add up to ¾ inch of insulation at the time of the installation.
Water Penetration Barrier
Water penetration barrier below each window and mullion prevents water penetration without the need to use silicone.
Silicone-Free Interior and Exterior
Silicone-free interior and exterior of OKNA bay windows ensures clean look of the finished product.
Standard Foam Insulated Mullions with Steel Rod
The mullions of bay windows are critical in helping to support the weight of the window because it projects outward. OKNA bay windows feature heavy-duty interior and exterior vinyl mullion profiles. The mullions are also reinforced with threaded steel rods for superior strength and stability. The cavity is filled with high density foam for additional thermal efficiency.
NO-Sag Support System
Our bay windows come with an adjustable turn-buckled cable support system to ensure that they will never droop or sag. Eyehook nuts are attached on two of the threaded steel rods and a 3” eyebolt lag is attached to the top of the window header or present roof overhang. The cables are attached to a turnbuckle and then it is adjusted to the precise pitch. Adjustable, hanging support system with 600 lbs. working load limit per brace.
HeatSeal Non-Metal Spacer
Most windows are manufactured with a metal spacer in between the two panes of glass, which may cause excessive condensation and heat loss. OKNA bay windows are manufactured with HeatSeal spacer. This non-metal spacer creates an excellent thermal barrier and reduces the transfer of heat and cold into the home.
Foam-Filled Window Frames
Windows sections in every OKNA Bay Window built out of Insul-Tec 500, Enviro-Star 800 and Casement 700 Deluxe Series come with insulated frame and sash for increased comfort and energy efficiency.
