Window film, also known as window tint, has many purposes. Window film is typically comprised of three layers with each layer having a unique function to help with everything from blocking light to protecting against scratches.
Some films are dark for shielding against harmful UV rays. Others are clear and intended to offer protection from damage. And some options are purely decorative.
No matter what type of window film you are working with, knowing where it can and cannot go is crucial for reaping the many benefits of these adhesives.
Where You Can Put Window Film
When a professional applies window film to the appropriate surfaces, it can be long-lasting and have many advantages. The following are various places you can put window tint to block the sun or protect against damage.
Sunroofs
A sunroof is a desirable feature of many modern cars. However, direct sunlight beating down on the driver and passengers can be unpleasant. Having a professional add window tint to the glass helps reduce the number of UV rays entering the car and makes for a more comfortable experience. Window tint for sunroofs can also reduce glare and make it easier to see while on the road.
Factory Window Tint
Many vehicle manufacturers use glass tinted with dyes and pigments for car windows. If you are interested in a darker look or adding a protective layer to the glass, a professional can apply window film to factory window tint without damaging the surface.
Single- or Dual-Pane Glass
Dual-pane glass uses two pieces of glass with air space between them for added insulation. If your home has single- or dual-pane windows, you can add window film to one of the pieces of glass to increase privacy or help control the inside temperature. Window tint can go on single and dual-pane glass, as long as the window’s surface doesn’t have a Low-E coating.
Smooth Glass
Applying window film is best on smooth glass surfaces. Whether you have a floor-to-ceiling window or a small sidelight beside a door, a professional can add a layer of film as long as the surface doesn’t have texture or damage.
Rear Window
Just like the side windows of a car, you can also use window film for back windshields. Rear window tint can give a car added privacy and help with temperature control.
Where You Cannot Put Window Film

Apply window film to compatible surfaces to reap its many benefits. The following are areas where you cannot put window tint.
Over Other Window Films
When working with window tint, you cannot add multiple layers to the same area. If a window already has a film on it, you must remove it before applying anything new. The adhesive on the film clings to the glass and not other films. Layering can make the glass hard to see through.
Damaged Glass
Whether the glass is cracked or chipped, damage to the surface will interfere with the film’s seal, and the layer will not stick without bubbling. Putting window tint over blemishes in the glass can impede your vision and leave the window looking unsightly.
Panels With Low-E Coatings
A low-emissivity coating, commonly called a Low-E coating, is a thin, transparent layer added to glass to reduce infrared and ultraviolet light from passing through.
If the Low-E coating faces the air space between the panes of the windows, you can add a window film to the room-side surface without interfering with any other benefits.
If the coating is on a single-pane window, it is best to skip adding window film entirely to avoid cutting down or eliminating heat loss reduction provided by the Low-E layer.
Plexiglas and Plastic Windows
Plexiglas and plastic windows are more examples of places where you cannot put window film. Whether they are room dividers or standard windows, the adhesive on the film can get absorbed into the plastic and leave behind unsightly bubbling. Applying tint to plastic can also create a permanent bond, leaving you unable to remove the film in the future. The removal process could even damage the window.
Textured Glass
Whether the glass itself is textured or has ornamentation such as paint or vinyl graphics, do not add window tint to surfaces that are not perfectly smooth.
Uneven surfaces are an excellent example of where not to put window film because the adhesive is only for bonding to glass. Any damage to the window or added elements can interfere with the film’s adherence to the window, leaving behind bubbles or other imperfections that make the glass challenging to see through.
