SunClad™ Double Hung Operation

SunClad™ 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 bottom sash tilts in by activating the finger release latches and pulling the top of the sash toward you. The top sash does not have tilt latches, it will simply pull toward you. The positive contact floating jamb liners maintain constant pressure against the sides of the sashes. This acts as an air and weather seal as well as helps in the vertical operation of the sashes. The jamb liners also 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 jamb liners. The balance shoes feature a locking action that supplies tension within the jamb liner 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. Tilting and sash removal instructions are available under the Technical section.

SunClad™ Extruded Aluminum Exterior

SunClad™ is the name we give our heavy-gauge extruded aluminum exterior on our clad-wood products. Aluminum is highly resistant to the effects of weather. It does not rust like other metal. It does not rot or decay, warp or distort like wood. It does not break down chemically over time like vinyl or fiberglass. Our heavy gauge extruded aluminum will not easily dent like Roll Form aluminum wrapped over a wood sash exterior. It provides exceptional strength and long life for the product and it is the perfect surface for our High Durability Powder Coat Finish.

• Superior Strength - for the frame and sash
• More Durable - protects interior wood components
• Protects the Home better
• Fail-Safe Water Management System - weeps water from frame and sash components
• Integral Nailing Fin - permanent fin is part of the frame
• High-Durability Powder Coat Factory Finish

Integral Nail Fin

SunClad™ products are designed with a rigid 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.

Fail-Safe Water Management System

All SunClad products are designed with a Fail-Safe Water Management System. The exterior perimeter of the glass is sealed against water intrusion. However, because aluminum, glass and wood all expand and contract at different rates, we design our Fail-Safe Water Management System to provide an effective drain path (to the exterior) for water to exit the glazing channel and sash structure. This prevents water or moisture from becoming trapped within the sash, which helps protect the insulated glass against seal failure and the wood interior of the window against deterioration.

Double Hung Exposed Jamb Liner

The SunClad™ Comfort-Tilt Double Hung window as well as the Easy-Tilt 3-1/8" Replacement frame features an exterior frame that does not conceal the outer face or edge of the vinyl jamb liners. This outer edge or face is visible against the window frame and the sash. While this does not hinder the functionality of the window, certain exterior window colors may make this more noticeable. Our upper grade Easy-Tilt Double Hung has a frame that conceals this part of the vinyl jamb liner.

High Durability Powder Coat Finish

Sun uses high durability powder coating as the exterior finish of our SunClad products. It is tougher than conventional painted finishes. The powder is electrostatically applied to aluminum extrusions that have been washed and prepared in a multi-stage pre-treatment process. The applied powder is baked on to the extrusion which is ready for production shortly after leaving the oven. Our standard finish meets AAMA 2604 requirements and allows us to provide a 20 year warranty against peeling, flaking, blistering, cracking, checking and loss of adhesion and a 10 year warranty against chalking and color change. An optional AAMA 2605 finish is also available and offers a 30/15 year warranty respectively. Sun offers 11 Standard Colors, 26 Feature Colors, 15 Metallic Finishes and 6 Anodic Finishes. Additionally, virtually any color you want is available through Custom Color Matching. Sun's Powder Coating is also very environmentally friendly, with no VOCs and no lead or chromium in any of the processes.

Beautiful Wood Interior

SunClad products feature a beautiful, high-grade, clear Ponderosa pine interior that is suitable for staining or painting. All wood components are treated with a wood preservative for long life.

• Select Clear Ponderosa Pine - beautiful, high-grade
• Suitable for staining or painting
• Preservative Treated against insects and decay

Comfort-Tilt Double Hung Plain Sash Lock Profile

The sash lock rail on our Comfort-Tilt Double Hung window features a plain profile. Our Easy-Tilt Double Hung features a rounded or "bullnose" profile for a more distinctive appearance.

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 & Panels

All SunClad™ Wood products use interior wood glazing stops that allow for the reglazing of the sash or panel should the glass ever be damaged.

Air-Tight Construction

A combination of our product designs, the materials we use and our manufacturing processes produce windows with outstanding air-infiltration performance. Complete weather-stripping and secure sash closure provide and air-tight seal. Our product air-infiltration ratings out-pace the industry standards and many of our competitors.

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.

SunClad™ Double Hung Configurations

SunClad™ 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.

Window Opening Control Device - Clad Double Hung

SunClad™ USA 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 or Brushed Nickel finishes. It is visible on the face of the side rail of the top sash.

Double Hung Glazing Method

Select the Dimension Sheet for the product you are interested in to view the details.

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.

For additional information see:
