A cracked, missing, or poorly fitting window air conditioner side panel can leave gaps around your unit, letting drafts, dust, and light into the room. The right replacement depends on more than BTU rating: check your window opening, the panel dimensions, and whether your AC needs a framed, adjustable kit or a fixed-size filler. These five options include adjustable frame sets for wider openings as well as a rigid PVC replacement set for shoppers who already know their panel measurements.

Our Picks: Best Window Ac Side Panel Frame reviews
1. Chiligent Window AC Side Panel with Frame: Adjustable Fit with Included Hardware
The Chiligent kit includes a left and right side panel with frames, a foam sealing strip, screws, and installation instructions. Its adjustable design is intended for most window AC units from 5,000 to 14,000 BTU, with openings up to 17 inches high and 42 inches wide.
The panels can extend up to 15 inches on each side, which may help cover a wider gap than a narrower replacement. The plastic material is designed to block light and help insulate around the unit. The panels can also be cut to adjust their height, so measure carefully before trimming.
This is a practical option if your existing framed panels are cracked or damaged and you want the foam strip and screws included in one kit. There is an important compatibility limit: the manufacturer says this set is not suitable for LG units. Confirm your AC brand and opening dimensions before ordering.
Pros:
- Adjustable for openings up to 17 inches high
- Designed for most 5,000–14,000 BTU window AC units
- Panels extend up to 15 inches on each side
- Includes foam strip, screws, and instructions
Cons:
- Not suitable for LG units, according to the product details
- Requires measuring and may need trimming to fit
Verdict: Choose the Chiligent kit if you need a framed, adjustable replacement with included hardware, provided your AC is not an LG model and your measurements fall within its stated limits.
2. Air Jade Window AC Side Panels: Soft Vinyl That Can Be Cut to Size
Air Jade’s replacement set comes with two framed panels, one for each side of the AC, plus a foam sealing strip and installation instructions. It is designed to fit most 5,000–14,000 BTU window units and window openings up to 17 inches high and 42 inches wide.
The panels use flexible soft vinyl and can be cut to fit the height you need. Their stated extension of up to 15 inches on each side makes this kit a possible choice for wider openings, though the actual fit depends on your unit and window layout. The foam strip is included to help seal gaps around the installation.
Compared with the Chiligent set, the listed fit range is similar, but Air Jade specifically describes its material as soft vinyl. Check your original frame and measure the window before buying; a BTU range alone does not guarantee a match.
Pros:
- Fits most listed 5,000–14,000 BTU units
- Adjustable height up to 17 inches
- Soft vinyl panels can be cut to fit
- Foam sealing strip and instructions are included
Cons:
- Does not list screws in the included package
- Requires checking the original frame and window dimensions
Verdict: The Air Jade kit is worth considering if you want flexible, cut-to-fit vinyl panels and its stated height and width limits match your window.
3. Bothyi Double-Layer Insulated Side Panels: Rigid PVC for Measured Replacements
Unlike the adjustable framed sets, the Bothyi kit is described as a pair of rigid PVC filler panels with a double-layer design. The product information lists panel dimensions of 10.91 by 13.74 by 12.76 inches and recommends measuring your existing panels or gap before ordering.
The rigid construction and adhesive backing make this a different style of replacement from the flexible, height-adjustable options above. The kit also includes insulation tape and installation accessories. Its description says the panels are intended to fill the space beside a window AC and help limit drafts, but fit depends on matching your opening to the listed dimensions.
This set may suit you if you have a fixed-size gap and prefer rigid panels over soft vinyl. It is less suitable when you need a wide, adjustable frame system or do not have clear measurements. Because the product dimensions are not presented as a universal opening range, check them against your unit before purchasing.
Pros:
- Double-layer rigid PVC construction
- Adhesive backing is included as part of the design
- Includes a pair of panels, insulation tape, and installation accessories
Cons:
- Does not list an adjustable height or window-width range
- Requires careful measurement to confirm compatibility
Verdict: Choose Bothyi when your existing panel area matches the listed dimensions and you want a rigid, double-layer replacement rather than an adjustable accordion-style frame set.
4. Pearwow Adjustable Side Panels: The Widest Stated Extension
Pearwow’s framed side-panel set is designed for most window AC units from 5,000 to 14,000 BTU. The product details state that the frame adjusts for openings up to 17 inches high and that the panels fit windows up to 42 inches wide.
Its standout specification is the panel extension: up to 19¼ inches wide on each side. That makes it the most explicitly wide-reaching option in this group. The soft vinyl panels can be adjusted and cut, and the kit includes foam strips to seal possible gaps.
The wider extension may be useful when standard panels do not cover enough of the space beside your AC. Still, the stated maximum opening width and the extension measurement are not a substitute for checking your own setup. The package description lists a left and right panel frame set and foam strips, but does not mention screws.
Pros:
- Panels extend up to 19¼ inches wide on each side
- Designed for window openings up to 42 inches wide
- Height adjusts up to 17 inches
- Soft vinyl panels can be cut; foam strips are included
Cons:
- Does not list screws among the package contents
- Compatibility still depends on your AC and window measurements
Verdict: Pearwow is the strongest fit to consider when you need extra-wide panel coverage and your opening stays within the stated 42-inch limit.
5. Powrocket Adjustable Side Panels: A Wide-Fit Kit with Screws Included
Powrocket’s kit includes two framed vinyl panels, a foam sealing strip, screws, and installation instructions. It is designed for most 5,000–14,000 BTU window AC units, with adjustable height up to 17 inches and a stated fit for window openings up to 42 inches wide.
The product description highlights wind- and dust-resistant vinyl and a widened design for larger openings. Unlike Pearwow, it does not give a specific extension measurement for each panel, so compare the frame and gap dimensions before relying on the “extra wide” description.
This kit may be a convenient pick if you want screws and foam included and are replacing cracked or damaged panels. As with any adjustable replacement, take measurements before installation and make sure the frame suits your AC model.
Pros:
- Designed for most 5,000–14,000 BTU window AC units
- Adjusts to openings up to 17 inches high
- Stated to fit windows up to 42 inches wide
- Includes foam strip, screws, and instructions
Cons:
- Does not specify the maximum extension width of each panel
- Requires checking the AC model and window measurements
Verdict: Pick Powrocket if you want an adjustable framed set with the foam strip and screws included, and your window falls within its stated fit range.
How to Choose a Window AC Side Panel Frame
Measure the opening and existing panels first
Measure the height of the window opening and the width of the gaps on both sides of your AC. If you are replacing an old set, measure its panels and frame as well. Compare those numbers with the product’s stated limits. A kit that fits a certain BTU range may still be the wrong size for your window.
Check the AC brand and model compatibility
Some replacement kits are described as fitting most units in a BTU range, not every unit in that range. The Chiligent listing specifically says it is not suitable for LG models. Check the product details and compare the replacement frame with the original before ordering.
Choose adjustable or fixed-size panels
Adjustable framed panels are useful when you need to adapt the height or width to your opening. The Chiligent, Air Jade, Pearwow, and Powrocket options are adjustable. The Bothyi set instead lists specific dimensions, so it is a better match when you can confirm that its rigid panels suit your gap.
Compare the material and panel coverage
The adjustable options use plastic or vinyl panels that can be cut to fit, while Bothyi uses rigid double-layer PVC. If you have a wide opening, compare each panel’s extension details rather than relying only on a general “wide” label. Pearwow gives a specific maximum extension of 19¼ inches per side; Chiligent and Air Jade state up to 15 inches per side.
Look for included sealing and mounting parts
A foam strip or insulation tape can help cover small gaps around the installation. Check whether the kit also includes screws or other mounting accessories, especially if you do not plan to reuse hardware from your old frame. The product packages differ, so confirm what is included before buying.
Plan for trimming and careful installation
Some panels can be cut to adjust their height, but trimming is a one-way change. Confirm your measurements and alignment before cutting. Follow the included instructions, position the panels evenly, and use the supplied seal where needed to cover gaps.
Frequently Asked Questions
Will any window AC side panel frame fit my air conditioner?
No. Fit depends on your AC model, the shape and size of its frame, and your window opening. Use the BTU range as a starting point, then compare the listed dimensions and compatibility notes with your own unit.
How do I measure for replacement side panels?
Measure the window opening height and the gap on each side of the AC. If you still have the old panels, measure their height and width too. Compare all measurements with the kit’s listed limits before ordering.
Can I cut adjustable window AC panels?
The Chiligent, Air Jade, Pearwow, and Powrocket product descriptions say their panels can be cut or adjusted to fit. Measure carefully before trimming, and follow the included instructions. The Bothyi listing focuses on fixed panel dimensions rather than cut-to-fit adjustment.
Do side panels help reduce drafts?
These panels are intended to fill the gaps beside a window AC. The supplied product details describe them as helping limit drafts or improve insulation, and some kits include foam strips or insulation tape to help seal gaps. The result depends on getting a close fit and sealing the installation properly.
Which option is best for a wide window opening?
Pearwow gives the largest specific panel extension in the supplied details, up to 19¼ inches on each side. Chiligent and Air Jade list up to 15 inches per side, while Powrocket states that it fits openings up to 42 inches wide but does not list a per-panel extension measurement.
Are these kits suitable for LG window AC units?
The Chiligent listing specifically says it is not suitable for LG. The other supplied product details do not give the same brand-specific exclusion, but that does not confirm compatibility with every LG model. Check the frame dimensions and the seller’s current compatibility information before buying.
What if I only need to replace one side panel?
Most of these kits are sold as a pair of left and right panels. The product details do not describe single-panel versions, so check the package contents and consider whether replacing both sides is appropriate for your installation.
Final Recommendation
For most shoppers looking for an adjustable framed replacement, Chiligent, Air Jade, and Powrocket offer a similar stated fit range, with differences in material descriptions and included hardware. Pearwow stands out when you need the widest specifically stated panel extension. Bothyi is the more specialized choice for a measured gap that suits its rigid panel dimensions. Before choosing, confirm your AC brand, window measurements, and package contents so the replacement fits your setup.
