UNITED Window Tint Film 20in x 100ft 20% VLT - Nano Carbon Privacy

In this review the UNITED 2-ply Nano Carbon window tint film is evaluated for drivers and homeowners who want privacy, heat rejection and long-term color stability. The single biggest reason to buy is its carbon-based, non-metalized construction that blocks most UV and IR while remaining signal friendly, making it a practical choice for anyone who needs reliable heat and UV protection without interfering with GPS or radio. The roll format and 20% VLT shade deliver strong daytime privacy and cooler interiors in a single, durable film.

Key Features

• UV & Heat Block: The film blocks up to 99% of UV light and reduces heat and glare to improve comfort and protect interiors from fading.
• 2-Ply Nano Carbon Construction: Two-layer clear PET with carbon particles offers lifetime color stability and better heat rejection than standard dyed films.
• Signal Friendly: Non-metalized composition ensures the film does not interfere with GPS, satellite, radio, or mobile reception.
• Flexible Installation Methods: The film can be applied wet and trimmed or bonded with heat-activated adhesive for dry installs on glass.
• Multiple Uses and Sizes: Available in multiple widths and VLT levels, the roll works on cars, trucks, SUVs and small home windows for privacy and style.

Who It's For

This film is suited to vehicle owners who want a durable, non-metal window tint that maintains signal reception while providing strong UV and heat rejection. It also fits homeowners seeking a privacy film for small windows that reduces glare and sun damage without a reflective metallic finish.

It is not the best fit for customers who require a fully mirrored aesthetic or ultra-dark blackout beyond 20% VLT unless they select a different listed shade. Professional installers will get the cleanest results; DIYers should be comfortable trimming and using a heat gun for the dry method.

Pros & Cons
