Window Tinting Soothes Summer’s Heat

If you believe the advertising from the folks that sell automotive window tint, you could assume that it is pretty amazing stuff. It prevents cancer by blocking the suns ultraviolet rays. It provides security by making it more difficult for thieves to break your cars windows. It protects you and your passengers from flying glass in an accident. It keeps the inside of your car cooler. It protects your seats and trim from cracking and fading. It provides privacy. It saves your eyes by reducing glare and harsh sunlight. And it changes the appearance of your car.

With record heat embracing most of the country, I thought it might be a good time to revisit the added used car value provided by window tinting for your car.

Cooling down the inside of the car is probably the primary reason people add window tinting to their car. Numbers vary by window tint manufacturer, but car owners can expect up to a 66% reduction in the amount of hear that enters the car.

There are a wide variety of window films and installation services available that range from $40 for the do-it-yourself kit to $400 or more for a professional installation. The amount of tint varies from just a slight tint to film that makes the windows appear almost opaque. To complicate the selection process, each state has different regulations regarding window tinting, making the choice of product dependent on where you are going to drive. What is legal in one state might get you a ticket in another state. It is always a good idea follow the advice of your professional window tinting installer to keep out of trouble with the law.

To start with, window tinting is a polyester film that ranges in thickness from 2 to 7 millimeters thick. An adhesive activated by moisture and pressure is applied to one surface. Bonded to the outside of the exposed surface (always on the inside of the car), there is a scratch resistant coating. In between the adhesive and the hardcoat is where the differences in window film can be determined.

The window film itself is dyed to absorb heat and block sunlight. This is the simplest technique used in the less expensive window films. More dye means darker windows. The darker the windows, the more heat and light are absorbed.

To absorb more heat without making the windows darker, some films add a layer of metalized film. The reflective metals provide a slight mirrored appearance without making the tint too dark. The additional bonded layers and complicated technology make these films more expensive. Your automotive locksmith might have an issue with metalized films that have been known to block signals from remote keys and security alarms.

When thinking about taking out an auto loan to purchase a vehicle, try looking for vehicles that already have all of the after-market upgrades, such as window tinting or a remote starter. This will allow you to put less money into your vehicle up front and only pay a few dollars more per month when going through the car financing process.

Applying the window film is not difficult but can be frustrating. First, it is important that the window glass is very clean. Wet film is placed on the inside of the car’s window. Air bubbles and excess moisture are pressed from between the film and the glass using a squeegee or rigid plastic card. Some processes require a blow dryer to mold the film and activate the adhesive. Excess film is trimmed away and left to cure for 3 or more days before the windows are rolled down. The tinted window film can be cleaned with any normal non-abrasive window cleaner and a soft towel after about 30 days.
