Windows are beautiful design elements that allow the natural light into our homes, offices, and buildings. However, windows can also be a source of problems. Windows can create glare; cause fading of your furniture, floors, artwork and curtains; make temperature control difficult and expensive; and reduce your privacy and security while you’re at home. If you are tired of struggling with these problems, there is a simple solution: window film.

Window film allows you to continue to enjoy the view through your windows while protecting you and your family from heat gain, glare, and harmful UV rays. Window film provides a host of benefits including enhancing comfort, saving money, increasing security, and providing you with peace of mind – all the while increasing the value of your biggest investment: your home.

Featured Products

At GSC, we are focused on providing the right product that will fit the needs and budget of our customer. We stand behind our products and installations and are committed to providing a superior customer experience from the sales process to the installation process.

Prestige Series

Designed to maintain the appearance of your home, Prestige Series Films combine reflectivity that’s actually lower than glass with films that allow up to 70% of the light into your home. The only thing you’ll see day or night, inside or out, is a beautiful window.

Safety & Security

Safety and Security Window Films help to protect your home and your family from threats such as break-ins and severe weather events like hurricanes. They are designed to help hold glass fragments together, reducing potential injury from flying glass during severe weather, and creating a stronger barrier to slow down criminals. Safety and Security Window Films are available in clear, safety-only versions, or as a combination film with both sun control and safety features.

Night Vision

Night Vision window films help block the sun’s damaging UV rays, reduce glare, and reject up to 73% of the sun’s heat. These darker shaded films are designed to reject solar heat that is produced from visible light. You can let up to 35% of the natural light into your rooms by day, and thanks to a low interior reflectivity, still enjoy the view out by night. Plus, higher exterior reflectivity means you can enjoy enhanced privacy with your windows both day and night.

Ceramic Series

Advanced ceramics allow these films to maintain their color and appearance over time. The ceramic series films reject up to 80% of the sun’s heat-producing infrared light and block 99% of UV rays. Slightly darker than the Prestige Series products, these films allow up to 50% of the light into your home.

Architectural Window Films

Architectural window films with stripes, squares and a variety of patterns. Films that provide semi obscurity with elegant design. Perfect for semi-privacy, decorative or architectural applications. Supplied with a silicone liner, which protects the clear, pressure-sensitive adhesive, and applied using the same tools and techniques for window films.

Frosted Window Films

Frosted films are designed with a variety of transparencies and light transmissions providing different degrees of privacy.


Acting as invisible protection, 3M Safety & Security Window Film can prevent tragedy by holding broken glass in place and delay an active shooter from gaining entry – thereby giving emergency personnel more time to respond to the impending threat.

  • General Solar did a fantastic job installing solar film on my family room and living room windows. The crew was prompt, neat, totally professional, and super good with clean up. The product is very effective and will definitely avoid fading of my furniture and rugs due to the sun. I totally recommend General Solar!Joan, Potomac, MD
  • General Solar did a very professional job of installing UV blocking film on my skylights…..what a difference in the comfort of my upstairs! The entire team was prompt, courteous, and conscientious. Highly recommend.Maureen, Arlington, VA
  • My wife and I recently moved into a transitioning neighborhood, and we had some concerns about security and break-ins. Window bars would have been expensive and ugly, so security film was the perfect solution for us. General Solar gave us a timely and fair quote, and was able to arrange installation right away. The installer was polite, professional, and did an extremely good job installing the film. In fact, after he finished up the job and was in the process of leaving, he came back because he noticed a tiny bubble left in one windowpane. I probably never would have seen it, but he went the extra mile to make sure everything was perfect. You can barely even tell the film is on the windows, but knowing that it is there provides peace of mind. My wife and I can rest easy knowing that our house, our pets, and ourselves are protected from break ins.Andrew, Washington, DC

101% Satisfaction
Location: Silver Spring, MD

Everything went well on Saturday. Your guy called to let me know his arrival time. He was prompt and courteous. He dedicated himself to the work that he had to do; and when he was finished, he gave me instructions so that we would allow the film to settle and not disturb it for a couple of days. And today the inspector found what he was looking for in the letter you sent. All in all, 101% satisfaction in all aspects of your team’s service. Thank you again

Better Than Expected

The guys did a great job. The results are better than expected. Thank you

Thank You
Location: Washington DC

I wanted to say thank you for replacing the film on our kitchen door! I honestly didn't understand the reverse effects of the mirror tint at night and the new clear security film is much more appropriate for its current application. I look forward to recommending the General Solar Company to friends and family.
