The types of materials that are found in window films will vary depending on what it is they are designed to do. Since there are so many uses for this type of covering, there are also a lot of different applications used to make each one.
Some types of glass covering products can be manufactured to keep out all light, such as those that are made to black out a room. They can also be made with the idea of privacy in mind. This usually means that they will allow light in, but will obstruct the ability of those passing by to peer into the home or office. They can also be designed to protect against burglary by being made stronger. The added strength makes it able to keep the glass from shattering should it become broken, either from someone trying to burglarize or vandalize, or from debris blowing in from a storm. They can also serve the primary purpose of keeping out infrared light or ultraviolet light to protect furnishings, artwork and even the occupant’s health and skin.
Because different processes allow the window films to perform different tasks, the materials used in production differ greatly as well. One of the most popular types of heat reflection or reduction materials used is ceramic. This option doesn’t have the types of dyes inserted in it. The dyes will make the covering begin to have a purplish hue as it ages. There are also no metallic properties to the ceramic varieties. The greatest thing about the ceramic material when compared to others that have dyes and metallic fillers is that ceramic does not fade and does not cause interference with cell phones and GPS systems. It is still able to block out the heat and sunlight, without interfering with electronic devices.
Security can be achieved by installing what is known as switchable window films. This type of material allows for a small voltage of electricity to pass through in order to turn it on and off. When it is off, the glass is clear. When it is turned on, the glass appears to have a frosted effect, which provides privacy.
The types of window films that are designed to keep shards of glass from exploding into a residence or business are made of very heavy gauge plastic. This allows for the plastic and the adhesive to hold all of the pieces together in the event that there is an impact of an object into the glass. Homes or offices in neighborhoods with higher crime or the likelihood of hurricanes and tornados often rely on these types of tints to keep their properties safer.
There are also decorative ideas for window films, complete with various etched appearing designs or faux frosting to make it look as if the glass has been specially coated. Of course, the types of materials that can be applied will also depend on the type of glass that is within the pane, and whether or not the glass is curved or insulated.
