In our quest to create more energy-efficient homes, we often overlook a major source of energy inefficiency: our windows. Unknowingly to most of us, a significant amount of heat is lost through them especially in the colder months, and in the warmer periods, they let in too much heat, putting an extra strain on our cooling systems. A practical and cost-effective solution that addresses this is the installation of window film.
Understanding Window Films
Window films are thin, multi-layered pieces of transparent material that are applied to the inside surface of windows. They are usually made from Polyethylene Terephthalate, a durable, flexible and clear polymer. Window films are designed to control heat transfer, reduce UV radiation, and cut down glare without significantly affecting the visibility, thereby improving the overall energy efficiency in your home.
Benefits of Window Film on Energy Efficiency
The primary way window films enhance energy efficiency is by regulating heat transfer. They do this in two ways: during winter, window films help retain heat inside your house, reducing the need for heating. In summer, the films reflect some of the sun’s heat away, reducing the load on your air conditioning system. By these two means, window films can help reduce energy usage and thus your utility bills.
Window films also protect against UV radiation – up to 99% of it. By filtering harmful UV rays, window films protect your furniture from fading and reduce the potential for skin damage when you’re out in the sun. You also enjoy a more comfortable indoor environment as there is less glare from the sun.
Types of Window Films
There are several types of window films designed to suit different needs. Insulating or Low-E films are ideal for colder climates as they help to prevent heat loss. Solar control films are great for hotter climates as they reflect away a great deal of the sun’s heat. Decorative films provide privacy while still allowing light through. Safety & Security films strengthen your window panes to make them more resistant to break-ins and extreme weather.
Deciding on Window Film
Like with any home improvement project, it’s important to do your research before making a decision. Consider factors like your local climate, the orientation of your windows, the type of glass you have, and your budget. It’s also crucial to remember that while DIY kits are available, professional installation is often recommended to ensure optimal performance and longevity for your window films.
To conclude, window films are a valuable addition to any home or building looking to improve energy efficiency. They are an investment that not only saves you money over time but also enhances comfort and protects against potential damage from the sun.
