Windows with grids between the panes can bring a divided-light look to your home without adding muntins you need to clean on the room-facing glass. The options below include fixed transom windows for bringing light above a door or along a wall, plus octagon windows for a decorative accent. Before ordering, check the rough opening, frame color, and exactly how the grid is installed—the product details do not confirm between-glass construction for every model.

OTIIALOT 31.5-Inch Octagon Window: A Large Geometric Accent
This fixed octagon window is the largest option in this group. Its shape makes it a natural choice when you want a decorative focal point rather than a conventional rectangular opening. The product details describe double-pane tempered glass, Low-E glass, argon between the panes, and a grid or grill design.
The listed actual size is 31.5 by 31.5 inches, with a 32-by-32-inch rough opening. Its welded main frame and 3.22-inch jamb depth are intended for a sturdy fit. The supplied product information also gives an NFRC U-factor of 0.30, solar heat gain of 0.23, and visible transmittance of 0.54. These figures can help when comparing window performance, but your overall results will also depend on installation and the rest of the building envelope.
This is a good style match for a room that needs a large, fixed accent window. It will not provide ventilation, and the supplied information marks its availability as unavailable, so check the listing before planning a project around it. The description mentions a grill but does not clearly say whether it sits between the panes; confirm that detail if easy glass cleaning is a priority.
Pros:
- Distinctive octagon shape for a decorative opening
- Low-E glass and argon-filled double-pane construction
- Tempered glass and a fully welded main frame
- Published NFRC performance figures
Cons:
- Fixed design does not open for ventilation
- Listing availability is marked unavailable in the supplied information
Verdict: Choose this model if you want a large octagon accent and can confirm that it is available and that its grid placement matches your needs.
NOTASA 12 x 72-Inch Transom: A Long, Narrow Light Source
The NOTASA is a fixed transom measuring 12 by 72 inches. Its long, shallow shape suits spaces above a door, in a garage, or along a wall where a taller window may not fit. The product description calls out double-pane tempered glass and internal decorative grids, a combination intended to add a divided-light look while keeping the glass surface easy to clean.
The frame is described as vinyl, with low-maintenance and weather-resistance claims in the product information. However, there is a detail to verify before ordering: the title identifies the window as black, while the description refers to white vinyl. Confirm the actual frame color and the rough-opening dimensions on the listing so the window suits your project.
Because it is fixed, this window adds light but not airflow. It is a practical option when you want a wide band of glass rather than an operable window. The supplied details describe the grids as internal, but confirm that they are between the panes if that specific construction is important to you.
Pros:
- Long 72-inch format for broad transom applications
- Fixed design can bring light into a space without taking up a tall opening
- Double-pane tempered glass
- Product description identifies the grids as internal
Cons:
- Does not open for ventilation
- Product title and description differ on the frame color
Verdict: Consider the NOTASA for a long transom opening, but confirm its frame color, fit, and grid construction before you buy.
BOBIBAN 10 x 29-Inch Transom: A Compact Fixed Option
This BOBIBAN window is a compact fixed transom, measuring 10 by 29 inches. Its proportions may work above a smaller doorway, in a hallway, or on an accent wall where you want daylight without a large glass area. The description lists a vinyl frame, double-pane insulation, tempered glass, and a classic grid design.
The fixed construction keeps the design simple but means it cannot provide ventilation. One specification needs checking: the title describes black tempered glass, while the product description refers to a white vinyl frame. Those details may refer to different parts of the window, but the supplied information does not resolve the mismatch. Verify the frame color, glass appearance, and rough opening with the seller before ordering.
The product description says the grids are decorative and easy to maintain, but it does not clearly state that they are sealed between the panes. If that distinction is central to your purchase, ask for confirmation rather than assuming the grid sits inside the insulated glass unit.
Pros:
- Compact dimensions for smaller transom spaces
- Double-pane glass is described as helping reduce heat transfer
- Tempered glass construction
- Fixed style needs no opening hardware
Cons:
- Does not provide ventilation
- Frame color and grid placement should be confirmed before purchase
Verdict: This is a reasonable size to investigate for a small fixed transom, provided the seller confirms the finish and grid details you expect.
COLORPAPA 10 x 48-Inch Transom: A Wider Band of Light
The COLORPAPA is a fixed white vinyl transom window measuring 10 by 48 inches. Its wider span can suit an opening above a door or garage where you want a horizontal strip of natural light. The product information describes double-pane tempered glass and internal decorative grids, designed to provide a traditional window pattern without putting decorative bars on the exposed glass surface.
The vinyl frame is described as low-maintenance and resistant to warping, peeling, and corrosion. Those are product claims, not a guarantee of performance in every installation. As with the other fixed transoms here, it does not open, so it is not a substitute for an operable window where ventilation is needed.
The listing description says the grids are internal, but it is still worth confirming that they are between the panes. Also check the actual size and rough-opening requirement before cutting or ordering; the supplied product information gives the window size but no rough-opening measurement.
Pros:
- 48-inch width offers a broader transom format than the compact BOBIBAN
- White vinyl frame is specified in the product title and description
- Double-pane tempered glass
- Product description identifies the grids as internal
Cons:
- Fixed window does not provide airflow
- Rough-opening dimensions are not included in the supplied details
Verdict: Pick this model to explore if you need a wider, white-framed fixed transom, and confirm its installation dimensions before committing.
OTIIALOT 23.5-Inch Octagon Window: A Smaller Geometric Accent
This smaller OTIIALOT octagon window has an actual size of 23.5 by 23.5 inches and a listed rough opening of 24 by 24 inches. Like its larger counterpart, it is fixed and uses double-pane tempered clear glass. The product description also specifies Low-E glass, argon gas between the panes, a welded main frame, and a 3.22-inch jamb depth.
The supplied NFRC figures are a U-factor of 0.30, solar heat gain of 0.23, and visible transmittance of 0.54. These offer useful comparison points, though they do not tell you how the window will perform in a particular wall or climate. The product information calls out grids for appearance but does not clearly specify whether they are between the panes, so check that point before buying.
Compared with the 31.5-inch model, this one needs a smaller opening and may be easier to place where a large accent window would feel out of scale. It still cannot open for ventilation. Its listed availability is marked as available in the supplied product data, but stock can change, so confirm the listing before ordering.
Pros:
- Smaller octagon size with a listed 24-by-24-inch rough opening
- Low-E glass and argon-filled double-pane construction
- Tempered glass and welded main frame
- Published NFRC performance figures
Cons:
- Fixed design does not provide ventilation
- Grid placement is not clearly specified in the supplied details
Verdict: This is the stronger OTIIALOT choice when you want a smaller octagon accent with published performance figures and a specified rough opening.
How to Choose a Window With Grids Between the Glass
Measure the rough opening, not just the window
Window size and rough-opening size are not always the same. Measure the framed opening in several places and compare those measurements with the manufacturer’s installation requirements. The OTIIALOT octagon listings provide rough-opening sizes; the supplied transom details do not. Do not assume a listed window size is the opening size you need.
Confirm what “between the glass” means for the model
Grids can be placed between panes or attached to the glass surface. These products are described as having grids, and the NOTASA and COLORPAPA descriptions call them internal, but the details are not equally clear for every model. If you want a smooth interior glass surface for easier cleaning, confirm that the grids are sealed between the panes before you order.
Match the shape and proportions to the opening
Transom windows are long and shallow, making them a fit to consider above doors, garages, and hallways. Octagon windows are more decorative and need a square rough opening in the sizes listed here. Compare the actual window dimensions with the wall space and the visual balance of the room or exterior.
Choose fixed or operable based on ventilation needs
All five products in this selection are described as fixed or non-opening. A fixed window can add light and a decorative detail, but it will not let you air out a room. If ventilation matters, look for an operable window separately rather than expecting a fixed transom or octagon to serve both purposes.
Compare glass and frame details carefully
Double-pane construction is listed across these products, while the OTIIALOT octagon windows also specify Low-E glass and argon gas between the panes. Tempered glass is named in the product descriptions. Compare those specifications with your needs, and avoid treating general insulation claims as a guarantee of energy savings in your home.
Verify frame color and installation information
Check the frame finish, glass appearance, jamb depth, and included installation details on the current product listing. The NOTASA title and description conflict on frame color, and the BOBIBAN title and description use different color wording for the product. Clear up those inconsistencies before purchasing, especially if the window will be visible from the exterior.
Frequently Asked Questions
What does “grids between the glass” mean?
It generally refers to decorative bars positioned inside a double-pane glass unit rather than attached to the exposed glass surfaces. The product details here do not clearly confirm this construction for every model, so verify the grid placement with the seller.
Do any of these windows open?
No. All five are described as fixed or non-operable. They can add light and a decorative look, but they do not provide ventilation.
Which window is best for above a door?
The transom styles are designed for above-door and similar applications. The COLORPAPA is 48 inches wide, the NOTASA is 72 inches wide, and the BOBIBAN is 29 inches wide. Choose based on your measured opening and confirm the required rough opening before ordering.
Which OTIIALOT octagon window is smaller?
The 23.5-by-23.5-inch model is smaller than the 31.5-by-31.5-inch model. Its listed rough opening is 24 by 24 inches; the larger model calls for a 32-by-32-inch rough opening.
Are the windows energy efficient?
The listings describe double-pane glass across the selection. The OTIIALOT octagon models additionally specify Low-E glass and argon gas, and provide NFRC performance figures. Actual performance depends on the full window assembly and proper installation, so compare the exact product specifications for your project.
Is tempered glass the same as impact-proof glass?
No. The product descriptions identify tempered glass as a safety feature, but do not describe these windows as impact-proof. Check the product’s ratings and applicable local requirements if impact resistance is important for your location.
What should I confirm before ordering?
Confirm the actual window size, rough-opening requirement, frame color, glass type, grid placement, and whether the window is fixed. Also check current availability, since stock can change and the supplied information marks the larger OTIIALOT octagon listing as unavailable.
Final Recommendation
For a decorative accent, the OTIIALOT 23.5-inch octagon is the most clearly specified smaller option, with Low-E glass, argon, and a listed rough opening. For a long transom, compare the NOTASA and COLORPAPA by width, while confirming grid placement and frame details before you buy. If easy cleaning and true between-pane grids are essential, get that construction confirmed for the exact model rather than relying on the word “grids” alone.
