The plastic covers on car windows are most commonly referred to as window deflectors or wind deflectors. They are aftermarket accessories that are installed along the edges of the window to direct air flow and prevent rain from entering the car when the windows are partially open.
Window deflectors, also known as window visors or rain guards, are acrylic or plastic accessories that attach to the edges of car windows. They create a small gap between the window and the car door frame to allow fresh air to flow into the cabin while keeping rain out.
By installing window deflectors, drivers gain the ability to crack their windows during inclement weather. This ventilation reduces fogging and heat buildup inside the car. Deflectors also help prevent rain from dripping into the vehicle when windows are partially lowered.
In addition to their functional benefits, many drivers install window deflectors for aesthetic purposes. They come in a variety of shapes, sizes, and colors to customize the look of a vehicle.

Names and Types
There are a few common names used to refer to window deflectors:
- Window deflectors
- Wind deflectors
- Window visors
- Rain guards
- Vent visors
- Vent shades
While these terms are often used interchangeably, there are some differences between certain types of deflectors:
In-Channel Deflectors
In-channel deflectors insert into the window channel between the glass and the rubber seal. This style creates a tight seal against water infiltration and is the most effective at directing airflow. In-channel deflectors are custom designed for specific vehicle makes and models.
Exterior-Mount Deflectors
Exterior-mount deflectors attach to the outside of the door frame using automotive-grade adhesive pads or clips. These are easy to install but may not seal as tightly. Exterior deflectors come in universal shapes to fit multiple car models.
Tape-On Deflectors
Some low-profile deflectors use heavy-duty automotive tape to adhere directly to the window surface. Tape-on deflectors are quick to install but may not last as long as other designs.
Benefits
Installing window deflectors has several advantages for drivers:
Ventilation
Cracking the windows open allows fresh air to circulate throughout the cabin, preventing the interior from getting stuffy in warm weather. Deflectors permit windows to remain partially open even during light rain or snowfall.
Defogging
The ventilation from open windows aided by deflectors helps keep windows clear by reducing condensation buildup inside the glass. This improves visibility for the driver.
Noise Reduction
Opening windows provides natural airflow that minimizes the need to use loud fans and blowers to circulate air in the cabin.
UV Ray Protection
The tinted acrylic or plastic material of most deflectors blocks ultraviolet rays, protecting interior surfaces from sun damage.
Smoke Reduction
For smokers, cracked windows prevent residual cigarette smoke from accumulating inside the vehicle.
Pet Comfort
Allowing fresh air into the cabin keeps pets cooler on hot days. Deflectors make it possible to take dogs along for rides while keeping the windows partially open.
Security
Together with cracked windows, deflectors enhance air circulation inside the parked vehicle. This air movement helps deter would-be thieves from breaking in, as it suggests the owner is nearby with the engine idling.
Considerations
There are a few things to keep in mind with window deflectors:
Wind Noise
Partially open windows can lead to added wind noise, especially at higher speeds. Some drivers may find this distracting.
Weather Protection
Deflectors are designed to prevent water intrusion in light rain, but may not keep the interior totally dry during heavy storms.
Aesthetics
Some auto enthusiasts feel window deflectors detract from a car’s sleek looks. Deflectors come in clear options, but tinted ones will always be visible.
Revised Airflow
The customized airflow around open windows may disrupt the vehicle’s climate control system. Vents and fans may need adjustment after installing deflectors.
UV Protection
While tinted acrylic deflectors filter some UV rays, they do not offer the same level of protection as automotive window tinting film.
Installation
Installing window deflectors is a straightforward process, especially for exterior-mount designs. In most cases, no special tools are required. Here are the basic installation steps:
- Clean the installation area thoroughly to remove dirt and debris.
- Peel off the adhesive backing and carefully apply the deflector to the window frame.
- Gently press along the entire deflector surface to create a strong bond.
- For clip-mount deflectors, fasten the clips around the edges of the window frame.
- Adjust the deflector placement as needed to ensure proper alignment.
Always consult the product instructions for the recommended cure time before rolling down the windows. The adhesive may take several hours to fully adhere in colder temperatures.
Popular Brands

Costs
Window deflector prices typically range from $50 – $150 per set depending on the material, design, brand, and vehicle-specific vs. universal fit. Here are some approximate price ranges:
- In-channel deflectors: $70 – $150 per set
- Exterior-mount deflectors: $50 – $100 per set
- Tape-on deflectors: $50 – $80 per set
- Chrome accent deflectors: $80 – $120 per set
- Custom fit deflectors: $100 – $150 per set
- Universal fit deflectors: $50 – $100 per set
Overall, in-channel and custom fit deflectors tend to cost more than exterior and universal options. Shoppers can also find group discount pricing when buying a full 4-piece set for the entire vehicle.
Maintenance
Window deflectors are designed to be low maintenance. However, a few tips can keep them looking their best:
- Wash occasionally with soap and water to remove dirt and debris. This prevents abrasion to the plastic or acrylic.
- Apply plastic trim restorer 1-2 times per year to restore faded, dried out deflectors.
- For tape-on deflectors, check adhesive regularly and reapply as needed.
- Avoid using harsh chemicals or abrasive scrubbers which can scratch the material.
- Check for cracking annually. Replace damaged deflectors to maintain functionality.
With occasional cleaning and checks, quality window deflectors should last for many years without issues.
Conclusion
Window deflectors, also called wind deflectors or window visors, allow car windows to remain partially open during inclement weather. The variety of styles include in-channel, exterior-mount, and tape-on deflectors. Major benefits include ventilation, defogging, UV protection, and pet comfort. Prices range from $50 – $150 based on fit, material, brand, and style. With periodic cleaning and checks, window deflectors are designed to provide years of trouble-free use.
