Low-E windows, or low-emissivity windows, have a coating on the glass that has changed rapidly over the past few years. There are many types of Low-E windows but not all Low-E glass coatings are created equal. Advances in technology have helped create a variety of Low-E glass types. In this post, we’ll compare Low-E 240 vs Low-E 366 glass.
These two types of Low-E glass in particular - Low-E 240 glass and Low-E 366 glass - offer many benefits that offer your home improved energy-efficiency and cost savings. Read on to see the key differences between these types of window glass.
Low-E window glass is glass with a low level of emissivity, also known as the ability of a material to emit energy as thermal radiation. By utilizing a thin, transparent coat, Low-E window glass reflects heat while allowing as much natural light as possible to pass through the window itself. Low-E also means that a house’s temperature can consistently reflect the interior temperatures inside while blocking exterior temperatures from passing through the glass (for a broader explanation, see our post on Low-E Window Glass).
When window glass glare is your top priority, Low-E 240 glass should be your Low-E glass of choice. A specially treated version of Low-E, this type of window glass is the best at controlling glare regardless of the level of light coming into your home.

As a reminder, Low-E glass is not a tint. Tinted glass works by absorbing sunlight and becomes hot in the sunlight. Low-E 240 glass coating is applied to clear glass, which results in a consistent appearance and performance of the coating regardless of the thickness of the glass.

Like other homeowner decisions, deciding between Low-E 240 or Low-E 366 depends on what your priorities are for your low-emissivity glass.
Both Low-E 240 and Low-E 366 offer incredible value and your decision will ultimately depend on your priorities and budget. Low-E 366 does offer a higher overall value. If you’re installing Low-E glass on just a few windows, making the investment in Low-E 366 might be best as it maximizes stopping UV and other harmful infrared rays.
If you’re looking to add an extra layer of protection or safety to your windows, Low-E windows could be the best option for you. Your windows provide so much for your home, and knowing the benefits and value of something like the Low-E glass coating could make the decision for how to best design your windows based on your budget.
