Product Summary
Construction and Materials
The OKNA Windows & Doors double-hung window is designed for durability and energy efficiency, utilizing advanced construction techniques and high-quality materials.
Construction:
- Frame and Sash: The primary construction material for the frame and sash is high-impact vinyl. This material is chosen for its strength, thermal performance, and resistance to weathering. The vinyl profiles are engineered with multiple chambers to enhance insulation and structural integrity.
- Multi-Chambered Vinyl Profiles: These internal chambers act as air pockets, significantly reducing heat transfer and improving the window's overall U-factor and R-value.
- Fusion-Welded Corners: Both the frame and sash corners are fusion-welded. This process melts the vinyl together, creating a strong, airtight, and watertight seal that prevents drafts and water infiltration, while also contributing to the window's structural rigidity.
- Reinforcement: Internal reinforcement, typically made of galvanized steel or aluminum, is integrated into the sash and frame members to provide additional strength and dimensional stability, especially in larger window units, preventing bowing or warping over time.
- Balance System: Double-hung windows employ a balance system to facilitate smooth operation of both the upper and lower sashes. Common systems include coil balances or constant force balances, designed for long-term reliability and ease of use.
- Interlocking Meeting Rail: The meeting rail, where the two sashes meet, features a robust interlocking design. This creates a tight seal when the window is closed, further enhancing its resistance to air and water infiltration.
- Lift Rails: Integrated lift rails are part of the sash design, providing ergonomic and durable points for raising and lowering the sashes.
Materials Used:
- Vinyl: Specifically engineered, multi-channel vinyl is the core material for the window profiles, offering excellent thermal insulation, low maintenance, and resistance to fading, chalking, and corrosion.
- Glass:
- Insulated Glass Unit (IGU): The windows utilize double-pane or triple-pane insulated glass units.
- Low-E Coating: A Low-Emissivity (Low-E) coating is applied to the glass surfaces. This microscopically thin metallic coating reflects infrared heat, helping to keep heat inside during the winter and outside during the summer, thereby improving energy efficiency.
- Inert Gas Fill: The space between the glass panes is typically filled with an inert gas, such as argon or krypton. These gases are denser than air and provide additional thermal insulation, further reducing heat transfer.
- Warm-Edge Spacers: The edges of the glass panes are sealed with warm-edge spacer systems. These spacers are made of less conductive materials than traditional aluminum spacers, minimizing condensation at the edges of the glass and improving the overall thermal performance of the IGU.
- Hardware:
- Locks: Locks are typically constructed from durable metal alloys, designed for secure operation and longevity.
- Balances: Balance systems are made from corrosion-resistant metals and high-strength spring mechanisms.
- Tilt Latches: The tilt latches, used to engage the sashes for tilting inwards for cleaning, are made from robust materials to withstand repeated use.
- Seals and Weatherstripping: High-quality, flexible weatherstripping materials, such as EPDM rubber or vinyl, are used around the perimeter of the sashes and frame to create a tight seal against air and water intrusion.

Frame Options
OKNA Windows & Doors offers a variety of frame options for their double-hung windows, designed to enhance both aesthetics and performance. These frame options allow homeowners to customize their windows to complement their home's architectural style and meet specific energy efficiency needs.
- Frame Materials: OKNA primarily utilizes advanced vinyl formulations for their window frames. This material is chosen for its durability, low maintenance requirements, and excellent insulating properties. Vinyl frames resist rot, corrosion, and fading, ensuring a long lifespan and consistent appearance.
- Reinforcement: To ensure structural integrity and enhance thermal performance, OKNA's vinyl frames often incorporate internal reinforcements. These can include multi-chambered designs that trap air for better insulation and strategically placed metal reinforcements for added strength and stability, especially in larger window units.
- Color Options: A range of color options is available for the vinyl frames, allowing for significant customization. Standard colors typically include classic choices like white and almond. Premium color options may also be offered, providing more flexibility to match exterior finishes, siding, or trim.
- Finish and Texture: The vinyl frames are typically produced with smooth, consistent finishes. Some options may feature a woodgrain texture, which can add a touch of warmth and a more traditional aesthetic, mimicking the look of natural wood while retaining the benefits of vinyl.
- Customization for Style: The various frame options are designed to integrate seamlessly with different home styles, from modern to traditional. The ability to select frame color and finish helps in creating a cohesive and appealing look for the home's exterior and interior.
Glass Options
OKNA Windows & Doors offers a range of glass options designed to enhance energy efficiency, comfort, and durability for their Double Hung windows.
The primary glass package available is the Energex system. This system includes:
- Quad-Pane Technology: This advanced configuration utilizes four panes of glass to create multiple insulating air or gas-filled spaces. This significantly reduces heat transfer, leading to improved thermal performance.
- Triple-Pane Option: A triple-pane glass option is also available, providing an additional layer of insulation compared to standard double-pane windows.
- Low-E Coating: All Energex glass packages are equipped with Low-E (low-emissivity) coatings. This microscopic metallic coating on the glass surface reflects infrared heat. In the summer, it helps keep heat out of your home, and in the winter, it helps keep heat inside, contributing to lower energy bills and increased comfort.
- Argon Gas or Krypton Gas: The spaces between the glass panes are filled with either Argon gas or Krypton gas. Both are denser than air and act as additional insulators, further reducing heat transfer and enhancing the window's overall energy efficiency. Krypton gas offers superior insulating properties compared to Argon.
Additional glass features and options that can be specified include:
- Tempered Glass: This safety glass is stronger than standard glass and designed to break into small, dull pieces when shattered, reducing the risk of injury. It is often required in certain building codes for safety reasons, such as in doors, near floors, or in bathrooms.
- Laminated Glass: Composed of two or more layers of glass bonded together with an interlayer, typically PVB (polyvinyl butyral). This construction provides enhanced security, sound reduction, and UV protection. If broken, the glass fragments tend to adhere to the interlayer, maintaining the integrity of the pane.
- Decorative Glass Options: While specific decorative patterns are not detailed, OKNA Windows & Doors generally offers decorative glass solutions to complement various architectural styles. These can include etched glass, tinted glass, or glass with integral grids for a more custom aesthetic.
- Obscure Glass: Used for privacy in areas such as bathrooms or where light transmission is desired without full visibility.
