subject: Window Film Lowers Cooling Costs [print this page] Corporations have pledged to reduce energy consumption and their carbon footprint in the near future. Some companies are purely trying to create a better environment both within their own offices and the environment as a whole. Others companies are investing in technologies to try to reduce energy costs in a time when increasing energy costs are impacting their profits. Homeowners are also taking the same approach in a bid to reduce their monthly household bills throughout the year.
Heat transfers throughout our environment all the time. Wherever you are, you are aware of things that are warm or cool or are getting warmer or cooler. Dive into a swimming pool or walk on a floor barefoot in the summer and you know about heat transfers. Radiation, Conduction, and Convection are the three main types of heat transfer.
On way to help reduce energy bills for both corporations and homeowners is to use Window film. In terms of heat transfer this uses radiation (commonly known as 'Heat Radiation'). This is one of the reasons why solar energy is also called solar radiation.
This type of energy is converted to heat when it comes into contact with a person or objects. So if you find a way to block the transfer of this energy you will then keep it from turning into heat this is because you prevent it from hitting anything?
By placing a layer of film on a window interrupts the transfer of this energy by reflecting the radiation back from the object. If you apply solar window film on the inside of a window within your office or home, the proportions are altered dramatically. The energy is reflected and absorbed meaning that it reduces the heat transmitted inside the room.
So in essence by using window film companies and homeowners are able to reflect a significant amount of solar energy away, whilst absorbing another percentage of the energy, resulting in considerably less radiation transmitted into the room. This then saves money when it comes to cooling a room via other means like an air condition unit.
