Gentek 1700 Series New Construction Windows: A Contractor’s Selection Guide
New construction windows must satisfy more than an architectural schedule. The selected windows must fit the framed openings, connect with the wall’s water-management system, coordinate with interior and exterior finishes, meet required performance criteria, and arrive in configurations the installation crew can identify and install correctly.
The Gentek 1700 Series gives builders and contractors a focused collection of new-construction vinyl windows with single-hung, sliding, and fixed-lite styles. Its value depends on matching the correct frame, glass, size, configuration, and installation details to the actual project.
What Is the Gentek 1700 Series?
Gentek developed the 1700 Series for new construction projects. Suburban Wholesale & Supply currently presents the collection with three principal window styles: single-hung, sliding, and picture or fixed-lite windows.
These products are intended for professional builders, architects, contractors, and remodelers who need windows designed to integrate with newly framed or fully exposed wall openings. They should not be confused with replacement windows designed to fit inside an existing window frame.
Contractors can review the collection on Suburban Wholesale’s Gentek 1700 Series new construction window page .
Start with the wall—not the window style
Before selecting a single-hung, sliding, or picture window, establish the wall construction, exterior cladding, opening dimensions, flashing strategy, structural requirements, interior finish, and applicable energy and building codes.
New Construction Versus Replacement Windows
| Project condition | What contractors should consider |
|---|---|
| New home | New construction windows can be installed while the framing, sheathing, flashing, and water-resistive barrier remain accessible. |
| Room addition | The windows can be planned with the new wall assembly and exterior cladding. |
| Full-frame remodeling | A new-construction product may be appropriate when the old frame and enough surrounding material are removed to prepare and flash the opening correctly. |
| Insert replacement | A replacement-window system is generally evaluated when the existing frame remains and the new unit must fit within it. |
“New construction” does not simply mean that the window is new. It refers to a product and installation approach intended to connect with the surrounding wall during construction. The nailing fin is part of that connection, but it does not create a complete water-management system by itself.
Available 1700 Series Window Styles
Single-hung window
A single-hung window typically has an operable lower sash and a fixed upper sash. It provides traditional proportions and controlled ventilation while limiting the number of moving sash components.
Sliding window
A sliding window operates horizontally and can be useful where projecting sash would interfere with a walkway, patio, porch, or landscaping.
Picture or fixed-lite window
A fixed-lite window does not open. It can provide an expanded view and natural light where ventilation or emergency escape is not required.
Window style should be selected according to room use, ventilation, cleaning access, furniture placement, code requirements, architectural appearance, and the expected exposure of each elevation.
Sales tip
Do not make every opening operable simply because operable windows appear more versatile. A planned combination of operating and fixed windows can satisfy ventilation needs while simplifying sightlines and controlling project cost.
Choosing Between Single-Hung, Sliding, and Fixed Windows
| Selection factor | Single-hung | Sliding | Fixed lite |
|---|---|---|---|
| Ventilation | Lower sash provides ventilation. | Horizontal sash provides ventilation. | No ventilation. |
| Exterior projection | No projecting sash. | No projecting sash. | No projecting sash. |
| Best proportion | Often suited to taller openings. | Often suited to wider openings. | Flexible, subject to size limitations. |
| Moving components | One primary operating sash. | One or more horizontal sashes, by configuration. | No operating sash. |
| Typical sales advantage | Traditional appearance and simple operation. | Useful for wide openings and tight exterior areas. | Natural light and views without an operable sash. |
These are planning considerations rather than universal rules. The exact size, configuration, clear opening, performance rating, and code suitability must be confirmed for every unit.
Frame Options Affect Installation
Gentek presents frame and accessory choices intended to help contractors coordinate the windows with different wall finishes and construction methods. The correct option should be selected before the windows are ordered.
Nailing fin
A nailing fin provides an attachment surface around the window perimeter. It must be integrated with flashing and the water-resistive barrier in the sequence required by Gentek, the project documents, and applicable codes.
Drywall return channels
Suburban Wholesale identifies 1/2-inch and 5/8-inch drywall-return channels as available features within the 1700 Series program. These channels can help create an interior drywall return without relying on a conventional wood extension-jamb assembly.
The selected drywall thickness and wall depth must be confirmed. A return detail that does not match the actual wall can create uneven reveals, additional labor, or an improvised finish.
J-channel and repair components
Integrated or coordinated J-channel can simplify certain siding transitions. Suburban Wholesale also describes a snap-on Quick Fix repair component intended to address damaged J-channel material.
This feature should not be interpreted as permission to ignore significant frame or flange damage. Confirm which component is damaged and whether the published repair is appropriate before making a field modification.
Metal-Reinforced Mulling for Window Combinations
Window combinations can create broader views and stronger architectural groupings, but connecting individual units introduces structural and water-management considerations.
Suburban Wholesale describes an optional metal-reinforced mulling system for the 1700 Series. A metal channel connects adjoining window frames to add rigidity during shipping and installation and provide reinforcement at mull intersections. The described system also incorporates a head drip cap intended to direct water away from the mullion.
Do not assume every combination is approved
The mull type, individual window sizes, total assembly dimensions, wind exposure, structural load, support, anchoring, and tested performance must be checked. Combining two individually rated windows does not automatically produce a combined assembly with the same rating.
Questions to answer before ordering a mulled unit
- Is the combination factory-mulled or intended for field assembly?
- Which reinforcement is required for the complete size and exposure?
- How will the assembly be supported during delivery and installation?
- Does the mull require an exterior drip cap or special flashing?
- What performance rating applies to the complete combination?
- Do the head, sill, and framing provide adequate structural support?
- Will interior and exterior sightlines align as expected?
Insulating Glass and Energy Performance
Gentek identifies Low-E glass, a warm-edge spacer system, and optional argon gas as available energy-performance components for its new construction windows. These features can reduce heat transfer through the insulating-glass unit, but they should be presented using the ratings for the actual ordered configuration.
Window performance varies by style, size, glass package, grids, frame, and operating configuration. Ask for the applicable National Fenestration Rating Council label or documentation instead of applying one published value to an entire project.
Important NFRC values
- U-factor: Indicates the rate of heat transfer through the complete window. Lower values indicate lower heat transfer.
- Solar Heat Gain Coefficient: Indicates how much solar heat enters through the window. The best value depends on climate, orientation, and shading.
- Visible Transmittance: Indicates the amount of visible light transmitted through the product.
- Air leakage: When included, provides information about air movement through the tested product under specified conditions.
Gentek cautions that energy savings vary and depend on proper installation and use. It also notes that not every product is ENERGY STAR certified and that insulating-glass units requiring capillary tubes may experience some argon depletion.
Sales tip
Present energy performance as a documented product comparison, not a guaranteed utility savings percentage. The window is one component of the building envelope, and actual energy use depends on the entire home and its occupants.
Performance Grade and Design Pressure
Suburban Wholesale states that Gentek new construction windows are designed with structural and weather-resistant performance in mind, including published performance grade and design-pressure information for applicable products.
A performance grade or design-pressure rating should never be converted casually into a guaranteed wind speed. Building height, location, exposure category, opening position, tributary area, pressure zones, topography, local code, and installation method all affect project requirements.
Verify that the exact window style, size, mull configuration, glass, anchoring, and tested configuration satisfy the project documents. A rating from a smaller window or different operating style may not apply.
How the AAMA Gold Label Helps
The Fenestration and Glazing Industry Alliance administers the AAMA Gold Label Certification Program for qualifying windows, doors, and skylights. The program includes product testing, manufacturing-plant inspections, and ongoing certification requirements.
A Gold Label can help contractors, inspectors, and project teams identify a certified product and its performance information. The label should be compared with the project requirements and documented before it is concealed by trim or finishes.
Certification is configuration-specific. It does not mean that every size, glass option, mull combination, field modification, or installation receives the same performance.
A clear homeowner explanation
“The certification label helps verify that the identified window configuration was produced under a recognized testing and inspection program. We still confirm that the exact unit is appropriate for this opening and install it according to current instructions.”
InstallationMasters and New Construction Windows
FGIA’s InstallationMasters program provides training and certification for installers of new construction and replacement windows and exterior glass doors. Its curriculum covers the process from initial site inspection through installation, cleaning, and maintenance.
For 1700 Series windows, the most important principle is that the window must be integrated with the complete wall. The nailing fin, flashing, water-resistive barrier, cladding, sill, fasteners, shims, insulation, and interior air seal must work together.
Installation planning checklist
- Verify rough-opening dimensions and allowable installation clearances.
- Check the sill for level, support, damage, and drainage.
- Confirm that jambs are plumb and the opening is reasonably square.
- Establish the sill-pan and flashing sequence before setting the window.
- Use compatible flashing, sealants, fasteners, shims, and insulation.
- Integrate the window with the water-resistive barrier.
- Do not bow the frame with fasteners, shims, or expanding foam.
- Keep drainage paths and weep openings clear.
- Test sash operation and locks before installing final trim.
InstallationMasters guidance does not replace Gentek’s current instructions, project specifications, engineering, or applicable building codes. FGIA states that manufacturer instructions should take precedence.
Questions Contractors Should Answer Before Ordering
- Which window style is required in each opening? Identify single-hung, sliding, or fixed-lite units on a labeled elevation or schedule.
- What are the exact unit and rough-opening dimensions? Do not order from nominal framing descriptions alone.
- Does the opening require emergency escape and rescue capability? Confirm applicable code requirements and the exact clear-opening data.
- What exterior frame option coordinates with the cladding? Review siding, masonry, trim, flashing, and J-channel details.
- How will the interior be finished? Confirm drywall returns, jamb extensions, casing, wall depth, and finished surfaces.
- Are any windows mulled together? Verify reinforcement, overall size, support, shipping, and tested performance.
- Which glass package is required? Check energy code, orientation, safety glazing, elevation, privacy, and project documents.
- Which labels and submittals must be retained? Establish NFRC, AAMA, safety-glazing, warranty, and inspection documentation requirements.

Popular Homeowner Questions
Are new construction windows better than replacement windows?
They serve different installation conditions. New construction windows are designed for accessible wall openings and integration with the exterior wall. Replacement windows are often selected when the existing frame remains. The appropriate choice depends on the project—not a universal quality ranking.
Is a single-hung window the same as a double-hung window?
No. A single-hung window generally has one primary operating sash, while a double-hung window has two operating sashes. Verify the actual product design and cleaning features before comparing them.
Are picture windows more energy efficient?
A fixed window eliminates operating-sash joints, but actual energy performance depends on the entire tested configuration, including size, frame, glass, spacer, and grids. Compare NFRC ratings rather than relying solely on the window style.
Does Low-E glass make the room darker?
Low-E coatings can affect visible-light transmission, but the amount depends on the selected glass package. Review the Visible Transmittance rating and an actual sample when daylight is a priority.
Are Gentek 1700 Series windows maintenance-free?
Vinyl reduces painting requirements, but tracks, locks, screens, weatherstripping, glass, drainage openings, and perimeter sealant still need inspection and cleaning. “Low maintenance” is more accurate than “maintenance-free.”
What warranty comes with the windows?
Suburban Wholesale describes Gentek new construction vinyl windows as backed by a lifetime limited warranty. The written warranty controls and should be reviewed for coverage, exclusions, transfer provisions, installation requirements, and claim procedures.
Advantages of the Gentek 1700 Series
- A focused selection of single-hung, sliding, and fixed-lite styles
- New construction frame design for integration with accessible wall openings
- Available drywall-return details for selected interior-finishing methods
- J-channel and related repair options for applicable exterior details
- Optional metal-reinforced mulling for qualifying window combinations
- Low-E glass, warm-edge spacer, and optional argon-gas choices
- Published performance and certification information for qualifying configurations
