The Sun Vinyl DH57 Double Hung window features sash-over-sash design. The top and bottom sashes open for ventilation and tilt-in for easy cleaning of the exterior glass surfaces.

The DH57 line features welded construction, pure virgin vinyl compound and an exterior frame that incorporates a built-in J-channel and Brick Mold profile. This makes it easy to integrate with siding while providing an additional trim accent.

All Sun Vinyl products provide excellent energy saving performance. Select one of our climate-targeted, Low-E insulated glass configurations to take advantage of Sun's best energy performance combination for your region. All Sun IG units use the Duralite™ warm-edge spacer system, a non-metallic spacer that provides the lowest thermal conductivity and best gas retention of any IG spacer system.

Sun Vinyl products never need painting and are designed to provide years of trouble-free performance.

Vinyl Double Hung Operation

Sun Vinyl Double Hung Operation

Sun Vinyl Double Hungs feature a sash-over-sash design where both sashes raise and lower for ventilation purposes. Both sashes will tilt inward for easy access to the exterior glass surfaces from inside the room. This can make it easier to clean your windows. The sashes tilt in by activating the finger release latches and pulling the top of the sash toward you. The side jambs house the spring balance system. The tilting action of the sashes is achieved by the combination of a pair sash pins, located near the bottom of each side of the sash, and a pair of balance shoes located in the jambs. The balance shoes feature a locking action that supplies tension within the jamb track when the sash is tilted 90°. This feature is useful to help prevent the bottom of the sash from moving up or down while the sash is tilted for cleaning. It will also hold the shoes and springs in position when you choose to remove the sash completely from the window.

Pure Virgin Vinyl
Pure Virgin Vinyl

Pure Virgin Vinyl Compound

Not all Vinyl Windows are the same when it comes to the quality of their vinyl compound. Sun Vinyl products use "Virgin Vinyl", which basically means it is all first generation PVC, without any recycled product added to its compound. This produces superior vinyl extrusion with improved strength and stability. Windows made from Virgin Vinyl will outlast windows made from cheaper PVC blends that include recycled product.

• Stronger Extrusions
• More Durable
• Greater Stability

Welded Construction
Welded Construction

Welded Construction

All Sun Vinyl products feature fusion welded frame and sash corners. This minimizes air and water penetration at all constructed joints, while a stronger, more durable window than one that is mechanically fastened.

Welded Construction
Integral Nailing Fin, J-Channel & Brick Mold
Integral Nail Fin, J-Channel, Brick Mold

Integral Nail Fin, J-Channel & Brick Mold

Sun Vinyl products are designed with a nail fin that is formed as an integral part of the exterior frame extrusion. This provides for a very strong and stable installation. The nail fin can be scored and removed for mulling and retro-fit applications. The frame extrusion also forms a J-Channel and a simulated Brick Mold. This allows it to integrate with siding applications and provide a trim accent.

Nail Fin, J-Channel, Brick Mold
Fail-Safe Water Management System
Water Management System

Fail-Safe Water Management System

All Sun Vinyl products are designed with a Fail-Safe Water Management System. The exterior perimeter of the glass is sealed against water intrusion. However, because vinyl and glass expand and contract at different rates, we design our Water Management System to provide an effective drain path (to the exterior) for water to exit the glazing channel and sash structure. This helps protect the insulated glass against seal failure.

Fail-Safe Water Management
Interlocking Sash
Interlocking Sash

Interlocking Sash

All Sun Vinyl windows with operating sashes feature interlocking sash rails. This provides a better air seal and more security when the sash is closed and locked.

Sun's Insulated Glass

All Sun products are glazed with Dual Glazed insulated glass. All of Sun's Hi-Performance Low-E Insulated Glass units are Argon filled and feature the Duralite™ warm-edge glass spacer system. Both dual glazed (using two pieces of glass) and triple glazed (using three pieces of glass) are available (depending on the product type). Tempered insulated glass units (both glass pieces) are standard on all door units. Sun manufactures these units in our own state-of-the-art insulated glass production facility, allowing us to produce the high quality insulated glass units for each order. This line is carefully monitored for quality control, glass testing and certification, to assure you that all Sun insulated glass is produced to the highest standards.

Duralite™ Warm-Edge Spacer

Duralite™ Warm-Edge Spacer System

All Sun insulated glass units use the Duralite™ warm-edge glass spacer system. Duralite is the only all non-metallic spacer system available. This gives superior thermal performance and its flexible properties provide a superior seal and excellent argon retention. It is one of the reasons we are able to provide a full 20 year warranty on our insulated glass.

Double Hung Configurations

Sun Vinyl Double Hung Configurations

Sun Vinyl Double Hung windows are available as single units or in mulled units up to 5 units wide. Individual units can be standard double hung style or as unequal sash height units known as Oriel and Cottage styles. An Oriel window has a bottom sash that is shorter in height than the top sash. A Cottage window is the opposite, with a bottom sash that is taller than the top sash. In each case, the sash height relationship is about 40% / 60%.

Double Hung Configuration Styles

Any combination of operating and fixed units can be joined into a mulled unit. Example: you can order a 3 window unit with a center fixed lite and a double hung on both sides. The individual units can be the same width or different widths. The main restriction is that the overall combined unit width cannot exceed 12' and the height cannot exceed 8'. Larger combinations may be mulled on site. Please note that mulled units are not designed to take the place of structural framing. In some instances it is better to order your units "aligned" but not mulled. This means that they will be built with the proper grille alignment to be installed beside or above each other, but the wall will have structural framing separating the units into smaller combinations or single units. More information on combination units is available under Mulls and Mulling.

Window Opening Control Device
Window Opening Control Device - Vinyl Double Hung

Window Opening Control Device - Vinyl Double Hung

Sun Vinyl Double Hungs have the option of having the sash opening limited by our Window Opening Control Device, also referred to as a WOCD. The device automatically limits the opening of the sash to a narrow opening, but it can also be by-passed or disengaged by an adult when more opening is wanted or needed.

1. The device is automatically set to limit the sash operation unless it deactivated by someone wishing to open the window. Open the sash and the WOCD stops it at the limited height.
2. To by-pass the limit, press the WOCD limiter inward. It is spring-loaded and part of the tab will protrude out from the surface of the device even in the by-pass position. Raise the sash upward and it will now continue past the limiter. Raise to desired height.
3. Closing the sash automatically re-activates the limiter.

Colors / Finishes
The WOCD is available in White. It is visible on the face of the side rail of the top sash.

Window Opening Control Device
Ventilation Stop Latch

Ventilation Stop Latch

Simillar the Window Opening Control Devise, the Ventilation Stop Latch is used to limit how far a sash can be opened. As shown on the right, it is flush with the face of the top sash side rail in its inactive position. When activated, it keeps the bottom sash from being raised beyond its stop height. It does not automatically activate and does not meet the requirements for WOCD codes. However, it is useful in non-code applications and is less expensive than the WOCD.

Egress Information

Egress Codes

Egress codes exist to provide emergency access to living areas of the home. These standards establish minimum requirements for windows used in bedrooms and basements with habitable space. At least one egress qualifying window or door is required in these rooms. If the room has a door to the outside, then this covers the requirements. If it doesn't, then at least one window must meet the code requirements.

Code requirements vary, depending on where you live. You must check with your local code officials to determine your specific requirements. There several code standards that are typically adopted, but the final authority exists with your local officials.

To help you select windows that potentially qualify, Sun has created an Egress ID system for our Casement and Double Hung windows. Please note that the window opening must be unobstructed, therefore Awning windows do not qualify. We base this on one of the typical, national standards, BOCA: The National Building Code. These standards happen to match many of the other code standards, but some do vary in some of the specifications.

Again, please check with your local code officials.


BOCA: The National Building Code, Chapter 10, Section 1010.4 (2006)

Maximum sill height above the floor = 44"
Minimum net clear opening width = 20"
Minimum net clear opening height = 24"
Minimum net clear opening square feet = 5.7
Exception - Grade level windows - minimum net clear opening square feet = 5.0

Energy Performance
Energy Peformance

Energy Performance

Energy Performance is reported as a group of values designated the National Fenestration Ratings Council (NFRC) to provide meaningful, comparative data for windows, doors and skylights. The NFRC has determined that these values represent the key energy performance factors when measured and reported in a standardized method.

These values are:
• U-Value
• Solar Heat Gain Coefficient (SHGC)
• Visible Light Transmittance (VLT)
• Condensation Resistance (CR)
• Air Leakage or Air Infiltration

All performance values are determined through product testing following industry standard specifications. Actual product performance will depend the specific details of the application in which the product is installed. This includes the how well the product was installed, the physical environment and conditions of the location as well as other factors.
