You may have heard the term ‘Low-E’ in relation to options that are available for reflecting heat and preventing energy loss in the home. Understanding a little about what low e film is and how it works could help you decide whether it may be a suitable option in your home or work place. What is Low-E film? Low E film stands for Low Emissivity film. It’s a very thin film made from polyester which has a micro thin, transparent metal coating. Low-E film can be stuck directly onto your current glass windows or doors to help to reflect radiant heat, which in turn reduces the amount of energy required in order to heat or cool your home. How Does Low E-Film Work? With low emissivity film, less heat is able to pass through the glass than with a standard pane of glass. Daylight from the sun can still pass into your home but the low e film helps to reduce the amount of long wavelength infrared heat that often escapes through windows and clear doors. Most Low-E films have an emissivity rating of around 0.33 – meaning that around 67% of the heat in a room is reflected back … Continue reading What Is Low-E Film?
