Removable Window Grids: Types, Names and Replacement Options
Removable window grids are decorative dividers attached to the room-facing side of certain windows with clips, pins or fasteners. Depending on the window manufacturer and product line, they may be removed for cleaning or replacement. They are different from grilles sealed between the glass and permanently applied divided-light bars.
What Are the Dividers in Windows Called?
Window grids may also be called grilles, muntins or window pane dividers. These terms are often used interchangeably by homeowners, although they can have different technical meanings.
| Term | What it usually refers to | Removable? |
|---|---|---|
| Window grid | General term for the decorative bars that divide a window into smaller sections | Depends on the type |
| Grille | The manufacturer’s term for the same part, used across most product literature | Depends on the type |
| Muntin | Traditionally, the structural bar separating individual pieces of glass | No, when it holds separate panes |
| Window pane divider | Informal homeowner term for any bar that visually divides the glass | Depends on the type |
| Snap-in or removable interior grille | A separate lightweight grille clipped or fastened to the room-facing side | Often yes, by design |
| Grille between the glass (GBG) | Bars sealed inside the insulated glass unit | No |
| Simulated divided lite (SDL) | Bars adhered or permanently applied to the glass surface | No |
| True or authentic divided lite (TDL) | Individual pieces of glass separated by muntin bars | No |
Types of Window Grids
Removable Interior or Snap-In Grids
Removable interior grilles are often described as snap-in or snap-on window grids. The exact attachment system may use clips, pins or manufacturer-specific fasteners. These are separate grilles attached to the interior face of the sash or glass. Attachment systems vary by manufacturer: some use clips, some use fasteners and some use pins, and the ones designed to permit removal are meant to come off so the full glass surface can be cleaned. The presence of a visible fastener is the practical sign that a grille belongs to this group.
Grilles Between the Glass
These bars are sealed inside the insulated glass unit, between the two panes, and are not homeowner-removable. There is no accessible surface behind them and no fastener to release. Changing or repairing them normally involves the insulated glass unit rather than removing a surface grid.
Simulated Divided Lites
Simulated divided-light bars are commonly adhered or permanently applied to one or both glass surfaces. Some product configurations combine permanent exterior bars with removable interior grilles, so identification must be manufacturer-specific rather than based on appearance alone — a bar on the outside of the glass does not tell you what the interior component is.
True or Authentic Divided Lites
These windows use individual pieces of glass separated by muntin bars. The bars are structural, they hold the glass, and they should not be treated as removable decorative grids.
Official manufacturer references confirm that grille configurations and removability vary by product line. Andersen, for example, describes removable interior grilles secured with fasteners or clips, while its simulated divided-light configurations can use permanent exterior grilles and either permanent or removable interior components. Pella describes grilles-between-the-glass as permanently sealed between the panes. Marvin distinguishes authentic divided lites, grilles-between-the-glass and permanently adhered simulated divided lites.
How to Tell Whether a Window Grid Is Removable
- Look for visible clips, pins or fasteners around the perimeter of the grille.
- Check whether the grid appears to be a separate lightweight frame sitting against the glass rather than part of it.
- Determine whether the bars are inside the sealed glass unit — if you cannot touch them, they are.
- Look for a manufacturer label, etched logo, serial number or product identifier on the sash or glass.
- Check the manufacturer’s instructions for that window series before releasing anything.
Do not pry against the glass, and do not pull on bars that appear glued or permanently attached.
If the attachment method is unclear, stop before applying force. Pulling on a permanently attached grille can damage the grille, glass, sash or finish.
Replacing Removable Window Grids
Replacement grids are generally manufacturer- and product-specific. Before requesting a replacement, collect:
- Window manufacturer
- Product line or series
- Approximate installation or production date
- Serial number or etched product information
- Window type
- Overall grille width and height
- Grid pattern
- Bar profile and width
- Material and color
- Clip or fastener style
- Clear photos of the window and the existing grid
A similarly sized generic grid or grille kit may not match the original attachment points, bar profile, pattern or color. Confirm compatibility before ordering or modifying a replacement.
The window manufacturer’s own replacement-parts resources are usually the right starting point, and product-identification markings help locate compatible parts — Marvin, for example, publishes guidance on where the laser-etched logo and product identifiers can be found on many of its products. Allnite Glass cannot obtain or fabricate replacement grids for every brand, so confirm availability for your specific window before planning around a replacement grille.
Removing and Cleaning Grids
Removal and cleaning are covered in detail on separate pages:
- Identifying your grid type and releasing the fasteners safely: how to remove window grids safely by grid type
- Cleaning the glass and the grille, then reinstalling it: how to clean behind removable window grids
- Grids in double-pane windows, including sealed between-glass bars: how to remove grids from double pane windows
Removable grids are most often taken off for cleaning, before glass or insulated-unit replacement, or because the grille itself is damaged, discolored or no longer sits flat. How a particular grille ages depends on its material, finish and exposure, so check the manufacturer’s care and warranty documentation for that product line rather than assuming a general rule.

Frequently Asked Questions
Homeowners commonly use the terms interchangeably. Traditionally, a muntin was the bar that separated individual pieces of glass in a divided-light window, so it was structural. A modern window grid is usually decorative and does not hold separate panes. Both terms, along with grille and window pane divider, are often applied to the same part.
Replacement grids may be available, but compatibility depends on the manufacturer, window line, measurements, grid pattern and attachment system. A grid sized to the opening will not necessarily match the original clip locations or bar profile, so confirm the specific window product before ordering.
Many interior snap-in grilles are designed to be removable, but the correct method depends on the manufacturer and the fastener type used on that window series. Check the manufacturer's instructions for the specific product line before releasing any fastener, and stop if the attachment method is unclear.
Not as an ordinary removable accessory. Grilles between the glass are sealed inside the insulated glass unit during manufacturing. Changing or removing them normally means replacing the insulated glass unit rather than detaching a surface-mounted grid.
Sometimes. Available options and compatibility depend on the window product and manufacturer, and some product lines have no retrofit grille option at all. Identify the manufacturer and series first, then confirm what that line supports before assuming a grid can be added.
Follow the original manufacturer's measurement instructions for that window series rather than relying only on the visible glass dimensions. Manufacturers specify how overall grille width and height are taken, and the visible glass opening is often not the dimension the replacement part is built to.
