3 Reasons to Consider Low-E Film Coating for Your Replacement Windows September 2, 2015 If you been trying to figure out what type of replacement windows to purchase for your Toronto area home, you probably came across a term known as ‘low E.’ Low E is a film coating that is applied to the glass of replacement windows at the manufacturer. It is designed to block a significant portion of the sun’s ultraviolet radiation. It operates based on the angle of light so that during the winter it doesn’t block as much of the sun’s UV rays as it would during the summer. That would allow some heat source to get into the house and help keep the home warm during those cold winter months. Here are three reasons why you should consider low E film coating for your Toronto area home. Reason #1: It can save money on utility bills. When you have low E film coating on your windows, it will cut down on the amount of heat generated inside your house during the summer. That will help you reduce your reliance on air conditioning, thus reducing your utility bills. Reason #2: It can protect your furniture, carpeting, and other items. The sun’s ultraviolet radiation can fade carpeting, furniture, books, papers, personal items, and more. When the sun’s UV rays are being blocked, it helps to reduce the risk of this fading and other damage. Reason #3: Aftermarket films aren’t as effective. If you want to save money upfront and consider getting something applied to the windows afterward, it’s not going to look great, it is difficult to apply, and there can be numerous problems with it. Low E film coating is translucent so you wouldn’t even know it exists on the windows in the first place. It’s a far better option to consider when purchasing replacement windows than to wait until later.
