Simulated Divided Lites vs. Grilles Between the Glass: A Window Design Style Guide

Window grilles, or grids, add character and enhance the traditional style of your home. Choosing between them may seem like a small detail, but the architectural impact of window bars can transform the look of your home.

Windows often have two options for window barsSimulated Divided Lites (SDLs) and Grilles Between the Glass (GBGs). This choice deserves careful consideration because it affects the appearance, maintenance requirements, and overall character of your home.

The real impact of window grilles on your home

While you'll love the beauty that well-designed window grilles bring to your home, their true value reveals itself in how they transform your property's character. The architectural impact of window bars add depth, dimension, and historical authenticity, that elevates your property's overall look and feel.

Window grille patterns for modern homes allow you to customize your windows to match nearly any architectural style, from traditional colonial to contemporary designs. The right window grille patterns can help your home stand out in the neighborhood while maintaining architectural integrity.

Key differences between Simulated Divided Lites and Grilles Between the Glass

There are two main options when it comes to grilles for fiberglass windows, each with distinct advantages:

How to choose the right window grilles

Consider these factors when choosing between SDLs and GBGs:

Window grille maintenance

GBGs require virtually no maintenance since they're sealed between glass panes. SDLs necessitate careful cleaning around the adhered bars, which can trap dust between routine window cleanings.

Aesthetic appearance

SDLs create a more three-dimensional, authentic appearance with shadows and depth, often attributed to more classical home styles. GBGs offer a cleaner, more contemporary look with flush glass surfaces.

Window grille cost differences

Generally, SDLs represent a premium option with higher costs due to their more intricate construction. GBGs tend to cost less while still providing a decorative window grilles pattern.

The hidden value—authenticity and character

Window grilles offer benefits that enhance your home's overall appeal:

  • Historical accuracy: For period homes, the right window grilles can maintain architectural integrity and historical authenticity.

  • Enhanced curb appeal: Well-designed window grilles can boost your home's appearance and potential resale value.

  • Reflect your style: Your choice of window grilles allows you to express your personal style while complementing your home's architecture.
