Low-E is something most homeowners hear frequently when shopping for windows or getting repairs done to their home KC home. To the average person though, it really doesn’t mean anything. It seems like every window brand and salesperson mentions it without a whole lot of explanation. As window film experts, to be honest, we use the phrase a lot too. So we are taking some time to explain just what Low-E is and isn’t and compare Low-E windows to windows treated with Low-E Window film–because their performance is very different.
Low-E Window Film vs. Low-E Glass
Technically speaking Low-E means “low emissivity”. But, that phrase doesn’t really roll off the tongue, does it? The term references the emissivity or travel or heat through the glass. If this “emissivity” is lower than the standard rating of .33–the glass of film can be deemed Low-E. So to be truly Low-E glass or window film they need to perform below a .33 in insulating and rejecting heat–which saves energy. But let’s compare the two because they are not the same. The clear winner in price and performance is Low-E window film. Today’s Low-E window films have ratings as low as 0.07. The translates to 93% of heat reflected from coming into your home and a whole lot of savings. Low-E glass windows that you would get in a full replacement (even the very best, most expensive Low-E glass) don’t perform nearly as well. In fact, it only performs the same as a mid-level Low-E window film and still costs over 10x more–not including custom-sized windows that will drive the price way up. There is also the hassle of having all the windows in your home replaced–not fun. So, if you are looking to stay in budget, have your windows made Low-E quickly, and get the most potent energy-saving technology–Low-E window film is the right choice for your Kansas home or commercial structure!=The Benefits of Low-E Window Film.
