In short: No.

One-way window film (often called "mirror film") doesn't work based on a magical one-way valve for light. Instead, it works based on light balance. The side with the most light becomes the "mirror," while the darker side can see through.

At Night: You turn on your interior lights. Now, the inside of your home is brighter than the dark yard outside. The "mirror" effect flips. People outside can see right into your brightly lit room, but when you look at the window, you’ll just see your own reflection.

When the weather is warm, window film can reduce air conditioning costs and save on lighting costs by reducing solar heat gain, while still letting in natural light. When it’s cold outside, window film can retain interior heat, saving on heating costs. In existing commercial structures, the energy savings achieved by window film can offer a payback in less than two years, or up to a 70% ROI — depending on factors such as construction, location, and type of film used. Window films can block up to 86% of the sun’s heat. A significant reduction of the sun’s heat aids in a building’s energy efficiency as less energy is needed from the HVAC cooling system — saving up to 30% of a building’s cooling costs.

The short answer: Yes, tinting home windows significantly reduces heat. Long answer: Whether it’s a residential home or a commercial business, it’s essentiall like adding a pair of high-end sunglasses to your home or business. Not only does it keep your living room from feeling like a greenhouse in July, but it also stops your furniture from "sunbathing" until it fades.

High-performance films capable of blocking 50–80% of solar heat, reducing indoor temperatures by up to in direct sunlight. It lowers air conditioning costs, blocks 99% of UV rays, reduces glare, and protects furniture from fading.

While it’s nearly impossible to eliminate all risk of fading, window film can significantly reduce the amount of fading for interior furnishings — protecting the flooring, artwork, drapes, and furniture that experience damaging sunlight from nearby windows.

Absolutely. For both commerical and architectural film, the useful life of window film can depend on the film type and the glass type. For buildings, window construction, building orientation, and geographical location come into play. Most residential and automotive applications are covered by a lifetime warranty for as long as you own your house or car. Most commercial installations receive either a 10- or 15-year warranty.

There are vast differences in the construction properties of automotive and architectural film. Automotive window film is designed to absorb solar energy, which means a car can actually grow warmer inside as the car sits idle. The magic of creating interior comfort happens as the window’s absorbed heat radiates as the car drives down the road.

Architectural window film, of course, is used on stationary structures. If one tried to install automotive window film architecturally, you can imagine how the solar-absorbing auto film would prove detrimental to a home or office environment. It’s for this reason that architectural flat glass is designed to reflect heat. In fact, if you were to try putting solar-energy-absorbing auto film onto flat glass, there’s a good chance heat buildup would cause the glass to break.

There are other differences. For example, automotive film is designed to be heat formed during installation, allowing the installer to shape the film as needed around the curvature of a vehicle’s windows. Architectural film uses a different adhesive than automotive film. It is formulated to give an installer more control when positioning film on large glass surfaces.

This depends on the film type, glass type, window construction, orientation, and geographical location of the building. 

All Madico architectural window films are covered by a warranty for some specified time. Most residential and automotive applications are covered by a lifetime warranty as long as you own the house or car. Most commercial installations receive either a 10- or 15-year warranty. There are some specialty films that have different terms; for example, exterior films are warranted for five years on vertical glass, two years on sloped glass; and decorative films usually have seven-year coverage.

The warranty coverage is based on extensive internal testing and our years of experience in the field. It is common that we see films that last well beyond their warranties, sometimes as long as 15-20 years.

Curtains and blinds only block solar heat and UV rays when they are closed but keeping them closed throughout the day is not always an option. Not only does window tinting remove the harsh UV light from entering your home, but it also reduces the sun's heat, glare and can reduce your energy bills.

Home window tinting typically costs between $5 and $15 per square foot installed, with most homeowners spending an average of $300 to $900 for a standard project. Total costs often fall between $500 and $1,500, with prices heavily influenced by the film type (ceramic, solar, or security) and labor.
