TRUE DIVIDERS VS. SIMULATED DIVIDERS, WHAT TO CHOOSE

Doors with Divided Lites

True Divided Lites (TDL) vs. Simulated Divided Lites (SDL): What’s the better option for you?

If you are in the market for windows and glass doors, you might have come across the phrases “true divided lites” and “simulated divided lites,” but these terms are rarely defined clearly.

What sets TDL apart from SDL?

The distinction between genuine and simulated divided lites often goes unnoticed, but to grasp both concepts well, we should clarify what a lite and a mullion represent.

A lite, which can also be written as “light,” means each individually framed section of glass in a window or door. Conversely, a mullion is the dividing line in a window or door; this division can be either authentic or simulated.

When someone describes a window’s lites as truly divided (TDL), they signify that the glass isn’t just one solid piece but consists of several pieces divided by mullions that pass through the glass.

In contrast, when referring to a window’s lites as simulated (SDL), it indicates that the glass is a large, single sheet featuring mullions placed atop it, which do not extend through the glass.

What are the advantages of each lite type?

Which style should I pick?

The favored aesthetic of having many small individual glass panes in a window or door is a timeless choice for historic neighborhoods, modern homes, or even minimalist designs. In some regions of the US, homeowners may be required to preserve authentic divided lites when updating their windows or doors. Some people choose this style for its visual appeal and upscale feel, while for others, simulated divided lites serve the purpose well.
