When it comes to buying replacement windows and doors, you have to admit, you’re not an expert. It’s not something you have to do on a regular basis, right? So why should you know all the ins and outs of the products on the market today? Luckily, when you live in St Louis, MO and surrounding areas, you have Masonry & Glass Systems to help you with all of the details! One thing you will want to learn about is low-e glass. Here’s a guide to help you determine whether or not it’s worth your extra money for your replacement windows and doors.

What is Low-E Glass?

Low-e glass, or low-emissivity glass, minimizes the amount of UV and infrared light that can come into your house through your glass. It does not, however, limit the amount of light that can enter your home. The thin coating is transparent and reflects heat. You can’t see it, but it helps to keep the temperature in your home consistent. When it’s hot, it will reflect the sunlight out and keep you cool. When it’s cold, it will reflect the interior heat back into your house.

Types of Low-E Coatings

There are several different coatings to keep in mind when you are thinking about low-e on your replacement windows and doors. The passive low-e coatings are also known as hard coats. These are applied to the glass ribbon while it is produced on the float line. The strong bond is very durable. The solar control low-e coatings are also called soft coats. These are applied off the line to pre-cut glass in a vacuum chamber. They have to be resealed in insulated glass. They have a lower emissivity and a better solar control performance overall.

What Type is Best for You

If you live in a cold climate, you might want hard coat low-e coating because it allows some of the infrared rays through, but not all of them. It helps to heat your home in the winter and keep your energy inside. In hot climates, the soft coat is best because it will protect you from UV rays and give you a better overall U-value. However, in St Louis, you get the best of both worlds. It is hot in the summer and cold in the winter. In these circumstances, the soft coat is the best way to go.
