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 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

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.

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.

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.

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 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.

Climate Matched Low-E Glass

Sun Windows offers Energy Saving Low-E glass that is matched to your climate. Select our ClimaGuard™ 63/31 Low-E glass if you are in a climate that has both heating and cooling seasons. Select ClimaGuar™ 55/27 Low-E glass if you are in a climate that mostly requires cooling. Both types use our Duralite™ Warm-Edge glass spacer and have air spaces that are Argon filled for an insulated glass unit that offers excellent thermal performance.

UV Fade Protection

Put an end to the fading of your carpets, floors, drapes, and interior furnishings from the daylight coming through your windows. Sun products provide the ultimate in UV Fade Protection with the use of our optional ClimaGuard SPF™ glass. ClimaGuard SPF™ glass blocks 99.9% of all UV rays.

Reglazable Sash

All Sun Vinyl products use glazing stops that allow for the reglazing of the sashl should the glass ever be damaged.

Weather Seals

All operating windows incorporate weather seals at the sash seams to guard against water and air leakage when the window is closed and latched.

Lead Times For Options

Since all Sun products are built to order, we offer a wide range of options for you to customize your windows and doors to meet your needs. Some of these options are part of the standard production flow while others are more specialized and may require additional time to produce. When a quote is created for your order, any extended lead times are indicated. This can assist you in planning your project and help you coordinate your workflow.

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%.

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.

Sun Vinyl Colors

Solid Vinyl Colors
Sun Vinyl windows are available two "solid vinyl" colors: White and Sand. These are the colors of the actual vinyl extrusions, not paint. Therefore, the exterior and the interior of the window are the same color.

Painted Exterior Colors
Sun offers two painted exterior color options on our White Solid Vinyl Window. You can have a painted exterior color of either Sand or Dark Bronze, while the rest of the window is white vinyl.

Note: The painted exterior color is factory painted, requires additional production time and an up charge. The exception to this is that our DH57 window has the Sand/White option in stock, so the production time is standard and the up charge for the color is much less.

Also Note: Due to the variations in color representation on computer monitors, the colors shown are for general reference only. For accurate color selection and matching, please obtain a color chart or sample swatch from your Sun Window Dealer or Representative.

Sun Vinyl - Hung Window Hardware

Sun Vinyl Single & Double Hung Window hardware consists of sash locks, finger release tilt latches, and side jambs that contain the sash guide tracks and spring balance system. The spring balances have locking pivot shoes that prevent the sash from slipping when tilted.

Hardware Colors
Sun Vinyl hardware colors are White and Sand, matching the interior color of the window.

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.

Operation
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.

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.

Double Hung Glazing Method

Sun Double Hung products are glazed with Dual Glazed insulated glass. Two pieces of glass with a 1/2" sealed airspace.

Glass Types

Most building codes now require thermally efficient insulated glass in windows and doors. Therefore, high-performance Low-E glass has become an industry standard. Sun offers a range of Low-E Insulated Glass units to match maximum thermal benefits with your region.

• ClimaGuard 63/31 is for regions that have both heating and cooling seasons.
• ClimaGuard 55/27 is for regions that require mostly cooling.
• Energy Advantage 63/31 and 55/27 add an additional Low-E surface to the their respective units for even higher thermal performance with the caveat that interior glass is coated and requires specials care when cleaning.
• Clear glass is available for specific applications where energy performance codes do not apply.

UV Protection Glass

Put an end to the fading of your carpets, floors, drapes, and interior furnishings from the ultraviolet light coming through your windows. Add ClimaGuard SPF™ to either of the ClimaGuard Low-E selections for the ultimate in ultraviolet protection. ClimaGuard SPF™ blocks 99.9 % of the UV rays, protecting your home interior from their harmful effects.

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 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

U-values and Solar Heat Gain Coefficient are used by the EnergyStar™ Certification Program to rate windows and door products as Energy Efficient. Additional factors, especially the Air Leakage or Air Infiltration rating, are critical in the overall, actual energy peformance of the installed product.
