Divided Lites
Divided Lites for Opening Glass Walls
Divided lites use horizontal and vertical bars across glass to create diverse grid patterns and added architectural detail.
NanaWall offers both simulated divided lites (SDLs) and mullions, providing customizable options to complement traditional and contemporary designs while creating a cohesive look across any project.
*SDL and mullion profile for NW Aluminum 640
Simulated divided lites (SDLs) are surface-applied to the glass, creating the appearance of individual panes within a single continuous pane.
*SDL and mullion profile for NW Aluminum 640
Mullions are horizontal profiles that divide a panel into two or more distinct glass or infill sections, often for added structural support.
Choose the Ideal Pattern
From classic Colonial and Craftsman grids to clean contemporary patterns, simulated divided lites and mullions can be customized to complement a range of architectural styles.
Explore different patterns and proportions with the NanaWall 3D Configurator to find the right look for your project.
SDLs create the look of individual panes without breaking up the insulated glass panels. The continuous glazing helps maintain energy-efficient thermal performance while achieving the look of traditional divided lites. SDLs are available for aluminum, wood, and aluminum clad opening glass walls.
For a more authentic true divided lite appearance, a spacer bar is applied between the glass panes. It creates the appearance of separate glass panes while maintaining a continuous, energy-efficient insulated glass system.
From traditional Colonial and Craftsman grids to clean horizontal patterns, simulated divided lites provide design flexibility across a range of architectural styles. Customize the pattern and proportions to complement your projects’ architectural aesthetic.
Slimline Steel Effect
With the slim nature of Generation 4 products, NW Aluminum 640, NW Acoustical 645, and NW Aluminum 840 can be customized with popular SE colors and a unique contemporary glass stop for a truly classic steel look while benefiting from the superior performance of an aluminum folding glass wall.
Simulated divided lites can be specified in patterns of your choice.
Mullions make it possible to combine different glazing and infill options within a single panel. Mix clear or frosted glass with solid infills like wood to create privacy, add visual interest, or meet project-specific design needs.
NanaWall thermally broken mullions provide added design flexibility while reducing heat transfer. Improved energy efficiency ensures interiors remain comfortable year-round.
Beyond adding visual appeal, mullions provide additional structural reinforcement for very tall opening glass walls. Mullions add strength to the overall system, allowing opening glass walls to meet structural requirements and aesthetic standards.
Compared to true divided lites, simulated divided lites, or SDLs, are bars applied to the surface of the glass to create the look of individual panes without dividing the glass panel itself. NanaWall SDLs offer a spacer bar to give an authentic appearance.
While simulated divided lites are applied to the surface of a continuous glass unit, mullions physically divide the glass into separate sections.
Yes. Simulated divided lites maintain a continuous insulated glass unit, supporting energy-efficient performance while achieving the look of divided glass.
Yes. NanaWall SDLs can be configured in a variety of grid patterns and layouts to complement traditional and contemporary designs. From Colonial to Contemporary patterns, explore the various customizable options and find the ideal gird pattern for your project in the NanaWall 3D configurator.
NanaWall offers simulated divided lites with NW Aluminum 640, NW Acoustical 645, NW Clad 740, NW Wood 540, SL45, SL70, and WD65 folding glass walls and HSW60 and HSW66 stacking sliding glass walls. SDLs are also possible with our Tilt Turn and Fixed window options.
