Hopefully, we haven’t lost you already! All the big words you see at the top of this post are related to a type of window that can be a huge improvement to your home. Low-E, or low emissivity windows are basically a special type of window that has an additional coating or two that help to block out undesirable elements like infrared or ultraviolet. Think polarized sunglasses, and you’re sort of on your way there.
The point is, Low-E windows can save you a lot of money in the long run by reducing the amount of energy that’s wasted by either heat escaping through your windows, or the sun heating the inside of your home when you don’t want it to. There are several different coatings and brands available, so be sure to do some research or consult a professional.
