Best Exterior Door Glass Inserts for Updating Your Entry Door
The best exterior door glass insert depends on your existing opening, door thickness, and preferred glass design. These products are replacement kits for compatible steel or fiberglass doors, not complete exterior doors. The 22-by-36-inch clear insert is a straightforward choice for a single-lite look, while the 9-lite options add divided-pane styling. For a 24-by-38-inch opening, consider ODL’s Low-E kit or DoubleFill’s ventilating design; Pushglossy is another 22-by-36-inch Low-E option. Measure the existing frame before choosing.

| Pushglossy 22 x 36 Low-E | Low-E glass in a smaller opening | Double glazing and sealed frame |
22 x 36 Clear Glass Insert, 1 Lite
This single-lite replacement kit is best for homeowners who want a clear, uninterrupted glass panel and have a compatible existing opening. It is listed for steel or fiberglass doors with a thickness of 1.75 inches. The stated door sizes include widths of 30, 32, 34, or 36 inches and heights of 6 feet 8 inches or 7 feet, with specified tolerances.
The kit includes tempered safety glass, maintenance-free frames, installation screws, and screw-hole plugs. Its exterior frame has a pre-applied dry glaze. The listed warranty is 20 years, subject to exclusions, including improper installation. Avoid choosing it based only on the nominal 22-by-36-inch label; verify the opening and door dimensions first. The listing also warns that storm doors must be vented to prevent heat damage.
22 x 36 Clear Glass Insert, 9 Lite
Choose this version if you want a nine-lite appearance in a compatible entry door. Like the single-lite option, it is intended for steel or fiberglass doors that are 1.75 inches thick. The listing identifies several door widths and two standard heights, with a tolerance of plus or minus 0.75 inch.
Tempered safety glass, maintenance-free frames, installation screws, and screw-hole plugs are included. The white frame provides a contrasting finish, so compare it with the existing door and trim before ordering. A 20-year warranty is listed, with exclusions for issues such as improper installation. This is not the better choice if you want one uninterrupted pane or if your current frame dimensions do not match.
ODL 24 x 38 Low-E Replacement Kit
This ODL kit is best for replacing an existing door-glass panel with outer frame dimensions of 24 by 38 inches, plus or minus 0.25 inch. It is designed for a 1.75-inch-thick steel or fiberglass door and is described as suitable for a half-light panel on a 6-foot-8-inch door. Its Low-E, double-pane tempered clear glass is the key distinction from basic clear inserts.
The manufacturer says replacing an existing insert of the same size typically takes under an hour and calls for standard tools, including safety glasses, a drill with a Phillips bit, and a putty knife. Two people are recommended. It is not a universal fit: confirm the outer frame dimensions and panel configuration before selecting it.
DoubleFill 24 x 38 Insert With Sliding Screen
DoubleFill is best for buyers who want a 24-by-38-inch replacement panel with built-in ventilation. The kit is described as fitting 1.75-inch-thick steel or fiberglass doors. Its double-pane glass insert includes a screen that slides vertically, allowing airflow adjustment without relying on a separate screen door, according to the product details.
The package includes a glass panel, frame assembly, special screws, and caps. Choose this design if adjustable airflow is a priority. Its larger 24-by-38-inch frame means it is not an alternative for a 22-by-36-inch opening. Verify the actual outer frame measurement and door thickness before ordering.
Pushglossy 22 x 36 Low-E Insert
This insert is best for a buyer seeking Low-E, double-glazed glass in a 22-by-36-inch replacement size. The listing gives outer frame dimensions of 22.75 by 37.75 inches, plus or minus 0.25 inch, and says it is designed for most entry doors with a 1.75-inch thickness. The exact outer frame measurement is important when comparing it with an existing insert.
The kit includes an insulated tempered glass panel, molded plastic frame, screws, and screw caps. Factory-applied seals and a frame pre-bonded to the glass are also listed. Same-size replacement typically takes less than an hour using common tools, and two people are recommended. Do not assume compatibility from the glass-panel size alone; check the frame and door thickness.
Buying Guide: How To Choose An Exterior Door Glass Insert
Which dimensions should you measure?
Measure the existing insert’s outer frame, not just the visible glass. Also confirm the door thickness and whether the door is steel or fiberglass. The products here are listed for specific sizes and configurations; a small difference can prevent a proper fit. Compare your measurements with the product’s stated tolerances and installation requirements.
Should you choose clear, divided-lite, or Low-E glass?
Clear single-lite glass gives the simplest, least divided appearance. A 9-lite design suits buyers who prefer a paneled look. Low-E double-pane options are available in both 22-by-36-inch and 24-by-38-inch formats in this selection. Compare the listed glass construction and design rather than assuming every insert offers the same insulation or appearance.
Do you need a screen or ventilation?
Most listed kits focus on replacing a fixed glass panel. DoubleFill specifically describes a vertically sliding screen for adjustable airflow. If ventilation is important, check the screen’s operation and the product’s dimensions. The 22-by-36-inch options are not interchangeable with 24-by-38-inch inserts just because both are door-glass kits.
What should you know about installation?
Several kits are intended to replace an existing panel of the same size. ODL and Pushglossy say two people are recommended; ODL also lists common tools for the job. Follow the product instructions and use appropriate safety precautions when handling glass. Check whether the package includes the frame, screws, and plugs before purchase.
