A Revolutionary New Product.

Smarter windows keep weather out where it belongs. 3M™ Thinsulate™ Climate Control Window Film is a low emissivity, or “Low E,” window film that helps improve the insulation value of a typical single-pane window close to that of a double-pane window, and of a double-pane close to that of a triple-pane.

Application of 3M™ Thinsulate™ Climate Control Window Film is much, much less expensive than actually replacing all that glass, and the results rival or match the performance, and appearance, of new glass.

Historic registered buildings, newer office towers, and every sort of building in between can be improved by the addition of 3M™ Thinsulate™ Climate Control Window Film. It enhances sustainability, comfort, and helps to provide fade protection, while remaining virtually invisible, with a neutral appearance that will not dramatically change the look of your windows—inside or out.


Virtually invisible insulation. Enhance comfort and efficiency year round with 3M™ Thinsulate™ Window Film Climate Control 75.

Frequently Asked Questions

What is Thinsulate?
Thinsulate™ is a well-known 3M brand that stands for comfort, warmth, and quality. The Thinsulate™ brand has been in existence for almost 50yrs. Many of the products under the Thinsulate™ brand are key warming/insulation components in jackets, hats, gloves, shoes, and bedding. And now Thinsulate products include low-e window films.
How is the film different from other solar control films?

Solar control films focus on the solar energy spectrum and are primarily designed to 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 preventing solar energy from entering a building is measured by its Solar Heat Gain Coefficient (SHGC).

While Thinsulate 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 help keep warm air inside during the winter months, and keep the warm air outside during summer months.

Thinsulate 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).

What is Low E and how does it work?
Low E is short for Low Emissivity. Products that have Low E properties, such as Thinsulate, are designed to reflect radiant heat, rather than allowing the glass to absorb it.
U value vs. Emissivity
Emissivity is the ability of a material to emit or absorb radiant heat. U value is a function of emissivity and is a measure of the heat transfer through a window. U value is the parameter used by the window industry to report the thermal effectiveness of a window.
How do I care for the film?
The Thinsulate 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 cloth. Never use abrasive cleaners or brushes to clean any window film.
How much additional insulation does Thinsulate provide?
Much like a chain is only as strong as its weakest link, 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. 3M 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.
Why Thinsulate vs. new windows?
3M 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!
Will this product interfere with my cell phone signals?
Cell phone signal strength within a building is dependent on the construction of the interior and exterior (envelope) of the building. While the Thinsulate product does generate some electromagnetic interference (EMI) we don’t expect that it will interfere with cell phone signals except when there is already a weak signal, and other building components are preventing the transmission of the signal.
