Though installing window film is sometimes done for decorative purposes, most homeowners who put it up do so for practical reasons. Window tinting can elevate the effectiveness of glass in your home in several ways without altering the structure of glass or frames. Replacing windows or installing storm windows can be a costly operation; window tinting is an inexpensive and quick way to reduce the amount of damaging rays that reach you through your windows and lower your cooling costs, as well. Installing window film may also increase safety if glass is accidentally broken.
Heat-Control Window Tinting
Those looking primarily to reduce energy bills, improve the comfort of indoor air, and save fuel and electricity should have a look at window films designed for heat control. These polyester laminated films reflect the sun's near-infrared energy back through the window to help you stay cooler in summer. They also have a proprietary coating that reflects radiant interior heat back inside to help you stay warm in winter. Remember to have film applied to all the windows of an enclosed room to achieve optimum comfort and energy savings.
Security Window Film
There is a new dimension in window film technology for property and personal protection against crime, violent weather, and accidents. Today, protecting yourself and your property is more important than ever. Safety and security films are tough, durable, and create a tear and penetration-resistant shield that bonds to the inside of your windows for protection. The film helps hold the glass together to reduce the chance of glass shards falling or flying out even under direct forces from winds, or impacts from flying objects.
Security window film can also provide added strength to hinder, or even deter, breaking and entering. Plus, window tinting gives whatever room it is installed in some added privacy. This is an especially nice addition in bedrooms, bathrooms, and in places where expensive equipment or collections might be seen by passersby.
Decorative Window Tinting
Practical applications aside, window tinting is also done for purely aesthetic reasons by homeowners who simply want to add a little flare to an otherwise bland setting. Decorative window film comes in many different varieties and mimics expensive installations such as etched or stained glass. It is far less pricey to install window film than it is to actually put specialty glass, and the effect is very realistic. Plus, it can easily be removed at a moment's notice if you decide that you want something different (an operation that would be far more costly if the glass were genuine).
Some decorative window film is made not to mimic other types of glass, but to provide a look all its own. Large pieces of window film can be purchased that contain bright, vivid paintings or patterns. When applied to a picture window, these films create a mural that will shine in the sunlight. Many of these films are meant to be easily installed and removed, so if you move to a different place or simply want to put the film on another window, you'll be able to do so with little trouble.
