3M THINSULATE WINDOW FILM FAQs

What Is Thinsulate™ Window Film?

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.

What Is Low E & How Does It Work?

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.

How Is The Film Different From Other Solar Control Films?

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).

How Much Additional Insulation Does Thinsulate™ Window Film Provide?

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.

How Do I Care For Window Film?

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.

Why Thinsulate™ Window Film vs New Windows?

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!
