Most drivers tint their side and rear windows but overlook the windshield — the largest piece of glass on the car and the source of the most direct sun exposure. Here is everything you need to know about windshield tinting, from Washington state law to film types and pricing.
Your windshield accounts for more sun exposure than any other window on your vehicle. It faces the sun head-on, and in the Seattle and Everett area, that means UV rays year-round regardless of whether the sky is overcast. Windshield tinting is one of the most effective upgrades you can make to your car — but it comes with specific legal requirements in Washington state that every driver should understand before booking an appointment.
This guide covers everything: what windshield tinting is, why it matters, what Washington law says, the three film types we offer, pricing, and what to expect from a professional installation at Compass Window Tinting in Everett.
Key Takeaway: You cannot legally apply dark tint to a windshield in Washington state. However, clear UV and IR-blocking films are fully legal and highly effective — and a top-edge tint strip up to 6 inches is also permitted. Professional installation ensures your film is legal, bubble-free, and backed by a warranty.
Windshield tinting is the application of a thin film to the interior surface of your front windshield. Depending on the film type and the portion of the windshield being treated, this film can block UV radiation, reject infrared heat, reduce glare, and add a layer of shatter-resistant protection to the glass.
Unlike the dark films used on side and rear windows, windshield films are typically optically clear or nearly invisible. The goal is not to change how your windshield looks — it is to change how it performs. You get all the heat rejection and UV-blocking benefits without any visible darkening that could compromise your field of view while driving.
There is also the option of a tint strip at the very top of the windshield, commonly called a visor strip. This darker section shades your eyes from direct sun during early morning and late afternoon driving — which is particularly useful in Western Washington where the sun sits low on the horizon for extended periods during winter months.
Washington state law (RCW 46.37.430) is specific about what is and is not permitted on front windshields. Here is what you need to know:
When you bring your vehicle to Compass Window Tinting, we will confirm the correct legal application for your specific vehicle and make sure your installation complies with Washington state requirements.

Even a clear, optically transparent film offers meaningful benefits that many drivers do not realize they are missing.
UV rays pass through untreated glass — including your windshield. Standard automotive glass blocks some UV-B radiation but allows a significant portion of UV-A radiation through. Long-term exposure during daily driving contributes to premature skin aging and increases skin cancer risk on the left side of your body (the driver's side). A quality windshield film blocks up to 99% of UV radiation, significantly reducing this exposure. It also prevents UV-driven fading of your dashboard, steering wheel, and interior upholstery.
Heat enters your car through two mechanisms: visible light and infrared radiation. Even on a cold, overcast Seattle day, infrared radiation passes through glass and raises interior temperatures. Our Nano Ceramic+IR windshield film rejects a substantial portion of infrared heat, meaning your cabin stays cooler and your air conditioning works less hard. In the summer, this translates to a noticeably more comfortable driving experience from the moment you get in the car.
The tint strip at the top of your windshield serves an underappreciated function — it cuts direct glare from the sun when it is low in the sky. In Western Washington, sunrise and sunset glare during fall and winter commutes is a genuine safety hazard. A properly installed visor strip eliminates the blinding effect without requiring you to squint through a sun visor that partially blocks your view of traffic.
Window film adds a thin but meaningful layer of structural integrity to your glass. In the event of a chip, crack, or impact, the film holds shattered glass together rather than allowing it to spray inward. This is a passive safety benefit that comes with every windshield installation.
We offer three film tiers for windshield applications, matching the same lineup we use for side and rear window tinting. Each tier is available for full windshield clear film, a top visor strip, or both.
Our entry-level windshield film uses carbon technology to block UV radiation and reject infrared heat. It is optically clear for full windshield applications and available in a darkened format for the top visor strip. This film carries a 10-year warranty and provides solid performance at an accessible price. For drivers looking to add UV protection and some heat rejection to their windshield without a large investment, Carbon Film is an excellent starting point.
Ceramic windshield film uses nano-ceramic particles that provide stronger heat rejection than Carbon Film, block 99% of UV rays, and maintain exceptional optical clarity. The film is GPS and cell safe — the ceramic particles do not interfere with any vehicle electronics or signals. The upgrade from Carbon to Ceramic is particularly worthwhile on the windshield, where optical clarity is critical for safe driving. Ceramic windshield film comes with a lifetime warranty.
Nano Ceramic+IR is our top-tier windshield film. It combines advanced nano-ceramic technology with a dedicated infrared rejection layer to deliver maximum heat blocking performance. This film blocks 99% of UV rays, rejects a high percentage of IR radiation, is scratch resistant, and is fully GPS and cell safe. For drivers who spend significant time behind the wheel in Western Washington — where sun angles can be deceptively punishing during winter commutes — Nano Ceramic+IR windshield film is the definitive upgrade. It comes with a lifetime warranty.
| Film Type | Price Range | UV Protection | Warranty |
|---|---|---|---|
| Carbon Film | $199 – $299 | Excellent | 10 Years |
| Ceramic Film | $250 – $350 | 99% | Lifetime |
| Nano Ceramic+IR | $299 – $399 | 99% | Lifetime |
Prices vary based on windshield size and vehicle type. Final pricing confirmed at time of appointment.

Professional windshield tinting is a precision job. The windshield is a large, curved piece of glass, and applying film to it correctly requires proper technique and quality materials. Here is what the process looks like when you bring your vehicle to Compass Window Tinting in Everett.
Step 1 — Cleaning. The interior surface of the windshield is thoroughly cleaned to remove dust, grease, and any contamination. Even a single speck of debris under the film will be visible and can cause problems over time.
Step 2 — Cutting. The film is precision-cut to match the exact dimensions of your windshield, including cutouts for sensors, wiper paths, and camera housings.
Step 3 — Application. The film is applied to the interior glass surface using a slip solution, then carefully squeegeed to remove all air and moisture.
Step 4 — Curing. The film requires time to fully bond to the glass. During this period — typically a few days — you may notice slight haziness or small water pockets. These resolve on their own as the film cures.
After installation, we review the work with you and provide care instructions. Your installation is covered by our film warranty from day one.
Many drivers tint their side and rear windows first, then consider the windshield later. Both are worthwhile, but they serve somewhat different purposes.
Side and rear window tinting provides privacy, heat rejection, and UV protection for all passengers. A dark tint on the sides and rear gives the car a distinctive look and significantly reduces the amount of heat entering through those windows. For a full treatment, see our auto window tinting service page.
Windshield film addresses the single largest source of UV and infrared radiation in the vehicle. Even with fully tinted side windows, an untreated windshield still allows substantial heat and UV through. Combining both treatments gives you comprehensive protection throughout the entire cabin.
If budget is a consideration, many of our customers start with the side and rear windows and add windshield film at a later appointment. The two installations are independent and can be done separately without any issues.
Washington state prohibits dark tinting on the front windshield. However, a non-reflective tint strip is allowed along the top portion of the windshield, typically the top 6 inches above the AS-1 line. Clear UV and IR-blocking films that do not visibly alter the glass are also legal and widely used. At Compass Window Tinting, we ensure every windshield installation complies with Washington state law.
Windshield tinting blocks UV rays that damage skin and fade interiors, rejects infrared heat to keep your cabin cooler, reduces glare from low sun angles during morning and evening commutes, and adds a shatter-resistant layer to the glass. Even a fully clear ceramic windshield film delivers all of these benefits without changing how your windshield looks.
Windshield tinting is priced by film type. Carbon Film runs $199 to $299. Ceramic Film runs $250 to $350. Nano Ceramic+IR runs $299 to $399. Final pricing depends on your windshield size and vehicle type. Call us at (425) 988-9877 for a specific quote.
A properly installed clear ceramic or nano ceramic IR windshield film will not reduce your nighttime visibility. These films are optically transparent — they block UV and infrared radiation while allowing visible light through. The top visor strip is positioned above the AS-1 line and does not interfere with your normal driving sightline.
With professional installation using quality film, windshield tint is very durable. Our Carbon windshield film carries a 10-year warranty. Ceramic and Nano Ceramic+IR windshield films come with lifetime warranties. Longevity is closely tied to installation quality, which is why we only use premium film and trained installers.
