What is Low-E Glass?

If you start shopping around for new replacement windows in Malibu, CA, you will quickly learn that vinyl windows are the leading material in the industry for a number of reasons. But even if you make the easy decision to go with vinyl early on, there will be a lot of other decisions you need to make. There are glass options, for example.  You can go with double or even triple pane and there are things like low-e coatings too. While you know that triple pane glass is, what’s a low-e coating? It’s a common term you’ll hear as you look around at vinyl windows and you will want to understand the components behind it to decide whether or not you want it on your vinyl windows.

Low-E Glass

Low-e stands for low emissivity glass. This technologically advanced glass has greater insulating qualities, which is never a bad thing for a hot location like Malibu, CA. It noticeable improves energy efficiency by reducing the transfer of air through the windows. Plus, low-e glass goes above and beyond by blocking out UV rays so you won’t have to worry about furniture, flooring, and other items fading from the sunlight. Sun is always nice in Malibu, CA, but not when it damages your stuff!


When you are getting new vinyl windows, low-e glass coatings have distinct advantages. The coating reflects heat back to its source, whether that’s outside your home or inside. That keeps your house cooler in the summer because the heat of the sun is reflected back outside. That also keeps things warmer in the winter because your internal heating is reflected back in. The coating doesn’t wear off or scratch, either, because it is placed on the interior portion of the glass so you’ll never be able to touch it. You can brighten a room without overheating it by the sunlight. You can also use the natural light to use less artificial lighting and you won’t have to heat or cool the house as much, either.

Becoming the Standard

Low-e glass is becoming a new standard that automatically comes with a lot of vinyl windows. But if you’re moving into an older home, the windows probably aren’t up to today’s standards. Whenever you replace windows with new vinyl windows, make sure you look into low-e glass. You can’t see it with your own eyes so you will need to check the labels to tell if it’s included. Low-e glass sounds like an obvious choice, but it does come with costs so you have to make sure the bonuses outweigh the initial costs. Since you’ll save money for the long haul, it usually does!
