This window mimics the classic, simple design of the Essential Double Hung, but with a fixed top sash that doesnt open. Ideal for hard-to-reach areas where the top sash would be difficult to operate, the Essential Single Hung window is finished with strong, durable fiberglass to the exterior and interior, making it virtually maintenance-free. Streamlined options offer just the right level of customization.

Product Features:

  • Available in heights up to 6.5 feet or widths up to 4 feet
  • Durable and low-maintenance material to the interior and exterior
  • Low-profile, easy to operate locking mechanism
  • Insert replacement option is available to fit seamlessly into existing window openings
  • Unique wash mode on operable panels allows cleaning of both sides of glass from indoors


Exterior Finish

A strong alternative to vinyl, our Ultrex pultruded fiberglass exterior finish is applied through a patented process to provide a superior, consistent finish. The American Architectural Manufacturers Association (AAMA) awards certifications to materials that pass numerous, rigorous tests. These tests simulate the harsh conditions that a finish will encounter throughout the life of the window or door. Passing these specification tests and achieving AAMA 624 verification gives independent verification that the Ultrex finish is best in class among fiberglass products.

Built for durability and low-maintenance, our Ultrex finish is 3x thicker than competitive finishes, with a smooth consistency and strong finish that resists fading, chalking, peeling and cracking, even in the darkest colors. If a design change calls for a new color down the road, our material can be painted without voiding our warranty. Six colors are available in neutral and dark tones.

Energy Efficiency

Glass is an important aspect for managing the energy efficiency of your home. Our standard glazing is dual pane: two panes of glass with Low E coatings and argon insulating gas. We offer variations to help meet climate and code requirements across the country, described in more detail on our glass page.


Screens for the Essential collection feature a durable, low maintenance aluminum surround and non-corrosive charcoal gray fiberglass mesh for consistent performance.

For cohesive curb appeal, all exterior screens are available in colors to match Ultrex fiberglass window and door exteriors.

Divided Lites

The look of multiple, individual panes of glass is popular in a wide range of architectural styles. Simulated divided lites and grilles between the glass mimic the look of these individual panes of glass without sacrificing energy efficiency.

Grilles-between-the-Glass (GBGs) Grilles are permanently installed between the glass panes for a low-maintenance, smooth exterior and easy cleaning. Choose from 13 exterior colors and 4 interior colors.

Exterior Trim

Get the performance of Ultrex fiberglass in convenient, factory-cut exterior trim made for easy installation and superior performance over time. Exterior trim is available in colors to match our exterior window finish, and several trim styles. Choose flat-style for a clean, simple look or brick mold-style for a more traditional aesthetic.

Window Opening Control Devices

Window screens are only intended to keep bugs out, not prevent a potential fall, so we offer Window Opening Control Devices that meet standards created to assist in the prevention of window falls in children under five years old. The Marvin Window Opening Control Device limits window opening to 4 or less when the sash is opened. The device may be disengaged, allowing for further operation to full opening for cleaning or egress and automatically re-engages when the sash is fully closed.
