There are so many different specialized windows today that it can be overwhelming trying to compare the different features and benefits that the windows offer. That’s why it’s so important to understand concepts like Low-E windows before you go to make a purchasing decision. Low-E glass is a specialized product that can help you save money and also improve the comfort of your home. Below we’ll explain what Low-E glass is and why it’s a big deal. Keep reading to learn exactly why you’ll want to at least consider investing in Low-E windows for your home.
What is Low-E Glass?
Low-E glass is specialized glass that comes with a microscopically thin coating that effectively reflects infrared light. This protective coating is completely see-through and it doesn’t stop any of the rest of the sunlight from making it into your home. This means that the glass will help protect your house, and help maintain internal temperatures, but it will also allow your home to remain bright all throughout the day.
Benefits of Low-E Glass
Low-E glass does a few different things at once to help your home remain comfortable throughout the day and to help lower your cooling costs throughout the year. The protective coating on the glass keeps out warming infrared light from making it into your home by reflecting it back out. This minimizes heat generation within your home from sunlight. It also helps reflect internal temperatures back into your home, serving as an insulating barrier to keep cold air in, or warm air in depending on the time of year that it is.
Finding the Most Effective Low-E Coating
There are several different factors for you to look at when choosing windows protected by a Low-E coating. When making a purchasing decision you have to look closely at the SHGC or Solar Heat Gain Coefficient of the window, its U-Value and its Visible Light Transmittance to find the best possible window. The lower the window’s SHGC, the better it is at preventing heat from moving from outside in. The lower the window’s U-factor the better it insulates against heat. Finally higher the VLT percentage, the brighter your windows will be and the less obstructed your view is. Keep each of these factors in mind when buying Low-E windows to help you compare different brands and models and to help you find the very best option out of them all.
Choosing Hard-Coat or Soft-Coat Low-E
There are two different types of Low-E coatings available today, soft-coat and hard-coat. Soft-coat low-E tends to be more expensive and difficult to manufacture, and it’s installed within the insulating part of the window itself. This coating offers the very best level of protection, but it’s more fragile. Hard-coat Low-E layers are easier to manufacture, far more durable, more affordable and slightly less effective. When deciding between these two options you need to look at prices very closely and decide using the cost difference and durability difference of the two options.
Low-E glass is an important part of modern-day windows, and with the information about you should be able to decide if you want to invest in this technology or not.
