Essential Casement Window

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 product line feature a durable, low maintenance aluminum surround and Marvin Bright View™ mesh – a fiberglass screen mesh that provides improved airflow and more natural light while keeping insects out. Bright View repels water and resists dirt and grime for a sharp, vivid view.

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

The look of multiple, individual panes of glass in a window panel is popular in a wide range of architectural styles. Grilles between the glass, available in a number of different styles, 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 low-maintenance and easy cleaning. Choose from six exterior colors and four interior colors.

Grilles between the glass are available in a selection of pre-designed patterns for added character. These are some of our most frequently-requested divided-lite patterns.

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 mould-style for a more traditional aesthetic.
