Window Film FAQs

A transparent film made of premium advanced plastic, metallic or glass laminate applied to the inside of residential or commercial buildings that does more than just provide tinting to block out the sun. Easier to install and less costly then specialty glass installations.

Yes, many films offer tremendous heat reduction properties. You can still enjoy a beautiful view and enjoy rooms that is are cooler and more comfortable. Which will also save energy & money.

Yes Window film doesn’t have to be dark to provide benefits like heat reduction, energy savings and ultraviolet (UV) protection. General Solar offers a wide range of window film shades for architectural applications, giving you options that best suit your needs.
Window film has an adhesive on one side that is protected by a clear liner. The liner is removed at the time of installation. General Solar professional window film technicians thoroughly clean and prepare the glass before installation. Using a special mounting solution, squeegee and trimming blades the film is then applied to the glass.
Yes! Window film can be custom cut to fit any size or shape of window, patio door, skylight and other glass. Each sheet of window film is custom cut to match exact sizing of your windows. This technique means there are no visible seams and the process works on single & double hung, dual pane, tempered glass windows, sliding patio doors, french doors, casement windows, storm windows and more.
Energy payback will vary depending upon the amount of sunlit glass exposure, the type of window film used, cost of application, type of glass, cost of utilities, and other variables. However, we have seen energy paybacks often range in the 2-5 year period, with some reported to be even less than 6 months.
Nothing completely stops fading but properly installed window films will reduce the major causes of fading (ultra violet light, visible light, and solar heat), thus prolonging the life of your furnishings, perhaps as much as two to five times.
No, 3M Window Films do not cause seal failure. We’ve been applying 3M Window Films to insulated windows for many years with several millions of square feet of film applied to date.
With properly selected window film that is professionally installed the likelihood of breakage is minimal.
Safety and Security Window Films are designed to make glass shatter-resistant by holding the glass pieces together when broken.

If you have a specific door that a pet paws on over and over we would recommend a tougher pet guard type of film for that door.
3M Window Films are warranted to maintain their solar properties without bubbling, peeling, cracking, or crazing. Many of our films are warranted against discoloration too. Contact General Solar for details.

3M Thinsulate™ Window Film FAQs

3M™ Thinsulate™ Brand is a well-known 3M brand that stands for comfort, warmth, and quality. The Thinsulate™ brand has been in existence for almost 50 years. Many of the products under the Thinsulate™ brand are key warming/insulation components in jackets, hats, gloves, shoes, and bedding. And now Thinsulate™ Window Film products include low-e window films.
Low E is short for Low Emissivity. Products that have Low E properties, such as Thinsulate™ Window Film, are designed to help reflect radiant heat, rather than allowing the glass to absorb it.
Solar control films focus on the solar energy spectrum and are primarily designed to help keep the sun’s energy from entering a building. In order to be effective, the glass needs to be exposed to sunlight. The effectiveness of a film in helping to prevent solar energy from entering a building is measured by its Solar Heat Gain Coefficient (SHGC).

While Thinsulate™ Window Film has properties that allow it to reduce the solar energy entering a building, the film is also designed to help prevent the transfer of radiant heat from one side of the glass to the other. Radiant heat is based solely on the temperature difference between the outside of the glass and the inside of the glass. Therefore, the Low E properties of Thinsulate™ Window Film helps keep warm air inside during the winter months, and keep the warm air outside during summer months.

Thinsulate™ Window Film helps reduce the amount of solar energy entering the building (SHGC) AND it helps provide additional insulation to reduce the transfer of radiant energy from one side of the glass to the other (U Value).

A home or building is only insulated as well as its windows. A single pane window loses 20 times as much heat as the same area in an adjacent well insulated wall. This leads to nearly 30% of all energy used to heat and cool homes going out the window. Thinsulate™ Window Film helps improve the insulation value of a typical single-pane window close to that of a double-pane, and of a double pane close to that of a triple-pane.
The Thinsulate™ Window Film should be cared for in accordance with the warranty document you received from your installing dealer. In general, you should wait a minimum of 30 days after installation before you clean your windows. At that time, you can clean your windows using commercially available window cleaning products with a clean window cleaning squeegee, or by gently wiping with a clean, soft cotton cloth, or non-abrasive paper towel.

Never use abrasive cleaners or brushes to clean any window film.

Thinsulate™ Window Films can be applied to your existing windows, increasing the performance of a single pane window nearly to that of a double pane and a double pane nearly to a triple pane. They achieve this at a fraction of the cost, disruption and time required to replace your existing windows. In addition, there is no need to discard your existing windows into a landfill!
