When you decide to replace your windows there are a lot of choices out there. You can choose what kind of frame you want. You can choose whether you want new construction windows or retro-fit windows. You can also choose whether you want to have double-glazed or triple-glazed windows. You can also decide that you want to use low-e windows.
What Are Low-E Windows?
If you have ever felt your windows when the sun is out, you may have felt how warm they can be. That's because glass absorbs a lot of heat and doesn't radiate it back out. Low-e stands for low emittance. Low-emittance means that the material doesn't doesn't absorb a lot of that heat and does reflect it back out. That means that less heat is going to come into your house. That makes the windows more energy efficient. The less heat the window absorbs, the less heat gets radiated into your house and the less your HVAC system has to work to keep your house at the right temperature.
How Do Windows Become Low-E?
Low-e windows aren't made of any special kind of glass. What makes them low-e is a special coating or film that gets put on the glass. That film helps to radiate the heat and sunlight back out and away from your house. Windows that are specifically made to become low-e windows may also be slightly concave. That means when you are looking at the window from the outside, it will very slightly curve in towards your house. That will also help to reflect the heat out.
Are There Benefits to Low-E Windows?
The biggest benefit to these windows is that they are energy efficient. If you are trying to cut your energy use and be more environmentally friendly, low-e windows will do that for you. The low-e coating can be installed on multi-glazed windows as well, increasing the environmental friendliness of the windows.
Are There Drawbacks to Low-E Windows?
There are a few drawbacks to using low-e windows at your house. One of them is that the windows are slightly more expensive. Another drawback is that the windows could possibly cause some damage to other buildings or fences in the area. That's because the heat and the light get reflected off the windows. If the windows are concave at all, they can focus that reflected light into one particular area. When your windows are installed, the window company will have to be aware that could happen and make sure that the windows aren't going to cause any collateral damage.
