The upper and lower sash are counterbal- anced by a spring powered block-and-tackle balancer mounted on the side of each sash. Tilt latches for each sash allow inward tilting for easy cleaning. When locked, a cam-type sash lock securely closes the upper and lower sash and seats them snugly into their weatherstrip systems. ADVANTAGES: • Upper and lower sash can be operated for ventilation. • Upper and lower sash tilt inward for safe and easy cleaning. • Surfaces on the sash and frame are designed with smooth radii which are visually pleasing and easier to clean. • Mortise-and-tenon appearance on the interior and exterior sash corners provides a traditional, hand-crafted look. • Full-perimeter weatherstrip provides superior weather tight- ness while allowing easy sash operation. • Sash are counter-balanced by a spring-powered block-and- tackle balancer mounted on the side of each sash. Each balancer is uniquely configured and engineered for that exact sash size and weight which minimizes operating force. • Corner keys provide durable, watertight corners. APPLICATIONS: • Homes and condominiums where traditional styling is important; appropriate for many restoration projects. • Sash do not project outward, making them suitable for areas facing walkways, decks and other exterior traffic areas. • Convenient in areas where the sash need to be cleaned from the interior. No need for ladders in hard to reach locations. • Visually compatible with other full frame and insert frame picture / specialty window prod ucts. ADVANTAGES & APPLICATIONS 03-3 COMPANY CONFIDENTIAL – REVISION AA-01 RENEWAL BY ANDERSEN SPECIFICATION & TECHNICAL MANUAL DB DOUBLE-HUNG WINDOW The following features contribute to the DB Double-Hung window’s low maintenance, energy efficiency, ease of operation, and pleasing appearance.

The two options are Full-Frame and Insert Frame. The insert frame option is available with two different sill configurations. A 14° sloped sill is available for insert applications where the existing window sill is angled to the exterior and a flat sill for use in other applications. Full Frame The full-frame DB Double-Hung window is the ideal choice for a Full Frame application. The interior of the window contains an extension jamb (EJ) kerf to accept an extension jamb. The exterior perimeter of the window frame can be fitted with a nailing flange OR multiple configurations of brick mould. Insert Frame An Insert Frame consists of a notched outer frame member that nests itself against the exterior sash stop of an existing 3-1/4” jamb pocket, and a CLOSED interior frame profile. The Insert Frame is available with both the Sloped Sill and Flat Sill. Insert Frame - Sill Options The DB Insert Double-Hung is available with two different sill options. If the existing window frame has a sloped sill of 8 degrees or greater, it is recommended to use a Sloped-Sill configuration. This will maximize the replacement window’s clear glass height as the sill on the new window is “sloped” at a 14 degree angle. However, the sill is void of an exterior kerf on the outer nose. The window, therefore, does not allow for attachment of accessories at the sill, such as L-Trim or aluminum coil. Additionally, a DB Double-Hung with a Sloped Sill cannot be configured with ANY exterior trim components such as brick mould or overfit. If the existing window frame has a sill with a slope of less than 8 degrees, it is recommended to use a Flat- Sill configuration. The Flat-Sill will seat better in these applications with minimal shimming required. Additionally, the Flat-Sill contains an exterior kerf to provide increased flexibility with exterior trim components or coil stock AND can be configured with brick mould or overfit systems. The Flat-Sill is also the appropriate selection when specifying a DB Double-Hung used in a bay/bow frame OR when mulled next to an Insert Picture/Specialty window (PW/SW). The Insert Frame consists of a 3-3/16” frame dimension which is ideal for nesting inside of an existing old dou- ble-hung jamb pocket (insert application). Factory applied exterior trim options are available for Full Frames. They are NOT available on Insert Frames. notched area of outer frame DB Double-Hung Full Frame DB Double-Hung Insert Frame DB Double-Hung Full Frame Sill DB Double-Hung Insert Flat Sill DB Double-Hung Insert Sloped Sill 03-6 COMPANY CONFIDENTIAL – REVISION AA-01 RENEWAL BY ANDERSEN SPECIFICATION & TECHNICAL MANUAL DB DOUBLE-HUNG WINDOW SLOPED SILL UNIT HEIGHT ADJUSTMENTS Sloped Sill Unit Height Adjustments When a sloped sill is desired, it is important to evaluate the EXISTING sill angle to which the new window will be resting upon. If the EXISTING sill angle is less than 14 degrees, a unit height deduction WILL BE MADE AT THE FACTORY to prevent interference. The chart below iden- tifies what deductions WILL BE MADE AT THE FACTORY based on the sill angle you identify on the order. The sill angle will NOT CHANGE on the DB Double-Hung window you are ordering. It will always be 14 degrees on a sloped sill configuration.

Limited Sash Travel Restrictions Based on Unit Type and Sizes All Renewal by Andersen® DB double-hung windows are indi- vidually engineered to optimize performance, operation and aesthetics. This includes each and every sash in the win- dow assembly which are counter-balanced by a coil-spring powered block and tackle balancer system mounted into the side of the sash. Each balancer is uniquely configured and engineered for that exact sash considering its size, weight and aspect ratio with the goal of minimizing the opening and closing force required for that given window. As a result, some window configurations may have sash travel that is limited. This is purposefully done to allow the counter-bal- ance-system to assist with maintaining operating forces much lower than typical double-hung windows. 12 0 0 12 24 36 48 36 24 60 48 84 72 96 Full Sash Travel Likely P o s s i b l e L i m i t e d T r a v e l Limited Sash Travel Likely EQUAL SASH (1:1) SASH RATIO Egress Compliance Based on Unit Type and Sizes An egress window is a window with a clear openable area, as defined by local building codes for as a means of escape in an emergency.
