Are you looking to make your home more energy-efficient at little cost? One way you can achieve this is by installing window film. Instead of having the glass replaced, you can simply apply this to the interior of your existing pane and change its heat and light transmission properties. But how exactly do window peels fit in the "green" campaign?

Sunscreen

During the summer and spring months, window film can block between 65 and 80 percent of the sunlight entering your home. It can also reduce heat gain by more than 75 percent.

The level of insulation will vary depending on the type and brand you purchase. Privacy film for windows tends to diffuse more light than say etched or stained glass window film. But you can always expect a certain degree of cooling and comfort. This, in turn, means you will not have turn on your air conditioner as frequently.

The air conditioner is one of the most power-guzzling appliances anyone can own. With its runtime shortened, you can enjoy lower energy bills. The monthly discounts may not be substantial, but these small dollars can add up to huge savings over time.

At the same time, you can do your share in protecting the environment. Not using the air conditioner as often translates to reduced carbon dioxide emissions.

In addition, you get to address concerns over the annoying glare on televisions, laptops and computer monitors. So if you live in an area with a generally hot climate, leave the film up throughout the year. To get the most out of your window peels, install them of the west and south sides of your home.

UV protection

Window peels can also block 95 to 99 percent of UV rays and consequently help in reducing heat buildup. This characteristic is also vital in maintaining the colorfastness of your curtains, carpeting, furniture and wood flooring. Otherwise, surfaces often exposed to UV rays will fade fast. There are health benefits as well. UV rays can be absorbed through the skin, so being protected makes you less vulnerable to skin cancer and rapid aging.

Heat loss

Even during cold winter days, window film can also be your ally. Able to retain 35 to 60 percent of the warm air inside, it helps keep your home cozy. Plus, the addition of this layer slows down heat flow through the glass pane. This means you can better regulate usage of your electric heater, thereby reducing power consumption.

Such treatment is particularly recommended if you have drafty windows and can feel the cold air every time you come near. So while you have not been able to pinpoint the exact cause (could be poor insulation and sealing around the frame or a loose pane) of this, window film makes for a quick and easy solution.

Tax credit

More good news? You have the government on your side, as it awards tax credit to those that introduce energy-efficient changes to their homes. You are eligible as long as the window film is installed in 2009 to 2010 and compliant with the qualifying insulation system. The tax credit is 30 percent of the product’s cost (excluding installation expenses), with the maximum at $1,500.

Window film can save energy and protect the environment in more ways than one. It is also among the most cost-effective means of reducing your electricity bills. So jump on the bandwagon and make your contribution in the fight against climate change.
