Residential Window Film

While natural sunlight offers plenty of positives for your home, there is a downside to letting the light shine in: increased energy costs, excessive heat, glare, and the fading of interior furnishings.  By eliminating or reducing these negative effects, you will be able to enjoy the benefits of your windows, transforming the comfort and efficiency of your home.  According to the EPA Energy Star Building Manual in the United States, approximately half of the home’s utility bills are wasted by loss of heat gain through untreated windows.  Film can help you save up to 50% on cooling cost without replacing your windows.

Most fabrics, furnishings and artwork can fade simply by allowing daylight to pass through an untreated window.  Window film blocks UVA and UVB rays, helping to protect fine antiques, woods and works of art from discoloration and fading.

Decorative film will help you add privacy to private spaces while making a bold design statement.  You can replicate the premium look of sandblasted glass, create unique patterns, add color, or intricate layered designs – All without sacrificing natural light or aesthetics.  It is the perfect balance between function and style, making it ideal for almost any application.

Residential Window Film FAQs


Does the film go on the inside or the outside of the glass?

Film is applied to the interior surface of the existing glass.  There is no need to go through the expense of replacing the glass.  At any point, the film can be removed without harm to the glass.  For difficult to reach windows, such as skylights we do have exterior film.

How do you attach the film to my windows? Will it be messy?

The film is carefully applied directly to the glass.  The first step is to thoroughly clean the glass and frames.  The film has an adhesive already applied at the factory, protected by a liner, which we remove prior to the application.  There are no odors or chemicals used.  A very small amount of soap, such as liquid Joy, is used in the water.  This “releases” the adhesive and allows the Film to be squeegeed to the glass. When installed properly, there are no bubbles or any distortion.  The film is cut into the window, leaving a very thin, usually less than a 1/8th of an inch margin around the edge.  Most the time this is imperceptible.

Towels and tarps protect the surroundings.  Minimal water is used.  In special cases, such as wallpaper in the jamb of the window, or silk drapes, we use plastic taped to the area to give additional protection.  Regular drapes and window treatments are not affected and usually can remain in place.  Upon completion, the area and window is restored to original condition.  

Do I have to take my curtains down or do you do that?

No… curtains and drapes usually remain.  If there is a special concern for delicate drapes, it may be advisable to have your drapery installer remove and re-hang the drapes. 

Should I have film put on all my windows or only the ones facing the sun?

It is recommended that all sun-facing windows be treated. If some windows receive less direct sun, we will apply a lighter film to those windows, for protection as well as uniformity.  All windows transmit UV, regardless of whether they face direct sun.  If fading protection is a primary concern and there are delicate furnishings or art work that needs protection, then use of film is strongly suggested. 

Can I put film on double paned windows?

Yes… Independent tests confirm that the use of film is harmless to dual pane glass.  If the windows are new and have a manufactures warranty, Seven Suns Glass Tinting can provide a matching warranty coverage on the Seal Failure portion of the warranty, as well as a 5 year thermal glass breakage warranty.  Your representative will review this option with you. 

Will my windows be darker once you put the film on? Can you see the film?

Our goal is to maintain as much natural light and clarity as possible on your windows.  If you have high windows, often times the glare and heat of the sun requires us to install a more tinted film.  However, it is still our goal to apply a film that provides you with the protection that you need, without taking away in any sense the quality and tone of the light, or in any way detracts.  You will be 100% satisfied with our products and services. 

How long will film last?

Today’s films can last as much as twenty five years.  Most residential films have a lifetime warranty for the original home owner and up to 12 year commercial warranty.  Realistically, windows in high traffic areas, such as exit doors, may be replaced sooner.  It is not unusual, however, that even these film panels will not be replaced for at least ten years. 

What kind of warranty do you give?

We are fortunate to offer products that come with LIFETIME WARRANTY and up to 12 YEARS for commercial customers direct from the manufacturer.  This warranty assures that you will be completely satisfied with our products for the entire time you live in your home.  If the product needs to be replaced under the warranty there is absolutely no charge to you.  All labor and materials are covered.  

If I sell my house is the warranty transferrable to the new owners?

The warranty is issued to the purchaser and is not transferable to the next homeowner. 

Are your installers bonded? How many people will be in my house during installation?

Depending on the size of the job, one or two installers could take a day or two to complete.  Usually installers will be able to take care of the job very quickly and efficiently.  We schedule jobs at your convenience and will make every effort to arrive at your home at the appointed time and complete the job within the promised time.  Seven Suns Glass Tinting is fully licensed, bonded and insured. 

How do I clean my windows after the film is installed?

 Windows can be cleaned with any commonly available window cleaning solutions and products, including ammonia based products, such as Windex.  Use of a squeegee or soft cloth is recommended.  The interior surface is specially treated with an acrylic “hard coat” to protect the Film and allows easy cleaning, without fear of scratching.

What happens if I scratch the film?

Minor scratching generally does not require replacement of the Film.  However, if a deep and unsightly scratch requires special attention, generally it is necessary to replace the panel. The Film can be removed and replaced quite easily and at a minimal cost. 

How long will it take to finish my house?

We always try to finish your home in one day.  If you have many French panes, or an unusually large installation, we may take slightly longer.  Every effort is made to have as many installers as possible to complete the job in one day.  Our estimators will review the estimated time with you.  Any special scheduling needs you may have will always be taken into consideration. 

I’m pretty handy --- Can I buy the Film from you and install it myself?

 It is advisable to have the Film professionally installed.  We service the Northern California region and are able to schedule jobs in Lake Tahoe area, or as far south as Monterey / Pebble Beach area.  We have installed large jobs out of state.  If, because of your location, you need to apply the Film yourself, we will ship Film directly to you, with application instructions.  Measure all of your windows and phone our Customer Service Team. 

Can window tinting help reduce glare on my TV screen and or computer monitor?

Yes, window film is often used to minimize the visible light that passes through windows to reduce glare on TV screens and computer monitors.
