Thinking about replacing your old windows to more energy-efficient ones, but lack the money to replace them? One simple, yet cost-effective energy solution is to have window film installed. Window film will help regulate the temperatures within the home, minimize your cooling costs and make the environment more comfortable.

Basically, window film is a thin sheet of window coating professionally and permanently installed on existing windows to deliver high-value benefits to a homeowner. Window film is rated by the National Fenestration Rating Council, as are new windows and doors, for consumer protection.

Introduced almost 30 years ago, today's window film uses advanced technology to deliver energy savings similar to low-e windows but at a fraction of what replacement windows cost. For single-family homes, window film installation costs can range from $3 to $11 per square foot, depending on the type of window film installed, and the process can be completed in one or two days.

Window film is available in a range of shades from clear to dark. Once installed, the energy conservation benefits are immediate. Also, did you know that the uneven glare coming in through older windows can cause hot spots and damage from UV exposure? Window film allows you to enjoy natural light without the negative impact of harsh glare and UV exposure.

Window film reduces energy consumption by reducing solar heat gain, reducing the homeowner's carbon footprint. Many window films can qualify for "green" credits and energy rebates and are considered carbon-negative products.

Window film is a good, cost-effective and long-term choice when you want to enhance structurally sound windows that function but are not up to contemporary standards. You can prolong the life of your existing windows by incorporating window film, saving money while being environmentally conscious.
