Sun Vinyl Hopper Operation

The Sun Vinyl Series 57 Hopper window features a single sash design that tilts in for ventilation. The Sash is bottom hinged and tilts inward at the top. It also features a utility latch to secure it in the closed position and a pair of side sash opening limiters to regulate the vent opening. The Hopper is a utility window, frequently used in basements where ventilation is desired but additional access is not needed or required.

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.

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 Sun Advantage 270 Low-E glass if you are in a climate that has a mixture of both heating and cooling seasons. Sun Advantage 270 is a second generation Low-E glass that permits 70% of the sun's visible light while blocking 86% of harmful UV rays. Select Sun Advantage 366 Low-E glass if you are in a climate that has stronger cooling requirements. Sun Advantage 270 is a third generation Low-E glass that reduces the amount of the sun's visible light to 66% while blocking 95% of harmful UV rays. 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.

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 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 - Hopper Window Hardware

Sun Vinyl Hopper Window hardware consists of a sash latch and a pair of sash opening limiters. This allows the window to open to the interior of the home with a minimal amount of sash intrusion.

Hardware Colors
The sash latch is unpainted steel.

Vinyl Windows Glazing Method

Sun Vinyl 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.

Glass Tints

All insulated glass units can be tinted. Tints available are: Bronze, Gray, and Reflective Tinted Glass. Tints are part of the glass, not a film. Never apply glass films to Sun insulated glass units.

Obscure Glass

All insulated glass units can include Obscure glass. Available Obscure textures are: Typical Obscure (P516) and Niagara Obscure (vertical waterfall pattern).

Tempered Glass

Most insulated glass units can be Tempered to meet glass requirements. Both pieces of the insulated glass unit are tempered. Most glass options (Low-E, Tints, Obscure) are available in tempered glass units.

Grille Types

GBG
GBG (Grilles Between Glass) are 3/4" contoured profiled aluminum grilles sealed within the insulated glass unit for no-maintenance convenience. Available in White or Sand.

Mulls & Mulling

Product Combinations
Sun Vinyl Windows can be combined with companion products to form special feature windows or window combinations. Sun Vinyl same series products are designed so that they can be easily grouped together to form multi-unit configurations. These configurations can be as simple as combining two units together, side by side, to form a 2-wide unit, or as complex as combining multiple units of various styles and shapes to form a special feature window wall. Send us your ideas and we will help you configure your special combination.

Mulled Unit Restrictions
The maximum over-all size for a factory mulled unit cannot exceed 12' by 8' (vertical or horizontal).
Maximum units wide = 5
Maximum units high = 4

Mull Caps or Covers
Mull Caps or Covers are available for mulling windows on the job site. Includes mull caps or covers only. (Installation is not provided).

Structurally Reinforced Mulls

Sun uses a specially designed, internal, structural aluminum mull reinforcement to add strength and rigidity to mulled units. This provides for a stronger, more secure installation. After installation, Sun Vinyl mulled units will not flex in the window opening like most competitor vinyl windows with weak mulls. You will have superior protection against storms with high winds and other extreme forces.

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.
