The low heat coating reflects the heat back inside reducing the radiant heat lost
Which is better low-e or double pane?
That's why we often say that Low-E glass options help to keep homes “cooler in the summer and warmer in the winter.” We should note here that Low-E glass is only one element of an energy-efficient window or glass door. Double-pane glass is much more insulating than single-pane; triple-pane is even better.
Why do my new windows look wavy?
Roller Wave. Roller Wave is a common type of visual distortion that may be visible in toughened glass units. It is caused during the glass toughening process when the heated and slightly molten glass is passed over large rollers whilst it is cooled. As a result, the glass may have a slightly waved finish to the surface ...
Do low-e glass windows look different?
Wrong: Low-E Glass Is The Same As Tinted Glass That's not true. Manufacturers can tint windows by adding alloy materials to the glass, which can drastically change the color of the glass by the end result.
Is low-e glass worth?
Absolutely! Low-e glass options are definitely worth the investment. For just a few more dollars than standard glass, you get the energy savings and protection from low-e glass. And that little extra cost can pay for itself with the money you'll save on utility bills!
What are the different types of low-e glass?
There are two types of low-e glass: hard coat (online) or soft coat (offline). Hard coat low-e glass is made by coating the glass during production with a thin metallic oxide layer, effectively welding it to the glass surface. Soft coat low-e glass, or sputter coating, is applied to glass that has already been formed.
What are the disadvantages of Low-E glass?
DISADVANTAGES OF LOW E GLASS: IT'S MORE EXPENSIVE None of us like shelling out more than we have to – especially when there are cheaper alternatives out there. A soft-coat low E glass unit is generally more expensive to purchase for your windows than an uncoated standard toughened glass unit.
Does Low-E glass scratch easily?
Why is that? The coating is actually very difficult to scratch and is harder than the glass. For example, if you scratch the coating with a coin, it is the metal from the coin you see deposited on the glass surface itself rather than a scratch.
Does Low-E coating affect the U-value?
The lower the emissivity of the glazing, the lower the resulting U-value and using low-E secondary glazing a U-value of 1.6 is achievable. This not only reduces energy usage and the buildings carbon footprint but the embedded carbon in the original window is retained.
Get the Low Down on Low-E Coatings!
Glass windows and doors are key in creating the drama, contrast, and views we love about our homes and cottages. They are also essential to how these spaces function: they provide thermal insulation, control light/heat transfer, and contribute to overall energy efficiency.
What is Low-E Coated Window Glass?
Low-E coatings are transparent, very thin coatings added to the glass panes (glazings) of a window. They help regulate the passage of solar radiation through the window’s glass. Importantly, low-E coatings only reflect solar radiation at certain wavelengths (UV radiation and long/short wave infrared radiation).
How Solar Radiation Interacts With Windows: Why Low-E Coatings Are Important
Low-e coatings are a simple, yet brilliant solution to a difficult problem:
Passive vs. Solar Control Low-E Coatings: Understanding the Difference
How do window manufacturers ensure that a window’s low-E coating will lead to more comfortable interior conditions for homes in different climates? Wouldn’t homes in winter months/colder climates want to take advantage of as much heat from the sun as possible? On the other hand, wouldn’t homes in warm, sunny climates want to eliminate as much unwanted solar heat as possible?.
Energy-Efficiency Metrics
The following factors are the most important in determining the energy efficiency of windows and doors.
Low-E Coatings: Summarizing the Key Points
Low-E coating is a thin, transparent, yet slightly tinted coating added to glass windows to help control or regulate the passage of solar radiation (sunlight) through the window’s glass.

While performance features like low-E coatings and third-party metrics matter, what matters most is that your windows perform exactly how your home needs them to. That’s why we formulate our own glass units to meet specific solar and energy-control needs of different regions and climates.
How does heat transfer occur in multi paned glass?
Heat transfer in multi-paned glass units occurs through thermal radiation from a warm pane of glass to a cooler pane.
Why is low E glass better than other types of glass?
Because it resists ultraviolet light, low-E glass prevents sunlight exposure from damaging carpets, draperies, sofas and other furnishings . Plus, low-E glass reduces sunlight glare in a room.The coatings reduce glare and reflect the sun's heat away from the structure. While windows with low-E glass generally cost 10 to 15 percent more ...
How does emissivity work?
Low-E glass can filter 40 to 70 percent of the heat that is normally transmitted through standard window glass. It works by reflecting heat back to its source.
What is low E glass?
Glazed with an ultra-thin metallic coating thinner than a human hair, low-E glass filters out the infrared (heat) portion of the light spectrum while allowing the full amount of visible light to pass through.
Does low E glass hurt plants?
No! Low-e glass blocks excessive heat and UV rays that can harm plants, as well as providing extra insulation during cold weather. This website has helpful information on the topic.
Does low E glass help with utility bills?
When the summer sun penetrates your windows, temperatures rise and so do utility bills. Choosing windows with low-E glass, however, reduces the cost of staying cool. In hot climates, homeowners and building occupants need to know all their options for keeping cool air inside and hot air outside. One option is installing windows ...
What does E stand for in glass?
First, the “E,” which stands for emissivity. Emissivity is a measure of how much thermal energy (such as sunlight or indoor heat) is absorbed by or reflected away from a material. In the case of ordinary clear glass, emissivity is pretty high: The glass absorbs heat from the sun and transfers that heat through to the other side of the glass. ...
What is turtle glass?
Turtle Glassreduces glare and is tinted to allow a visible light transmittance of 45% or less from inside a home. Ideal for use in all coastal climates, turtle glass can be mandated by local building codes, especially for beachfront homes, because it helps prevent hatchling sea turtles, which navigate based on moonlight, from moving inland toward manmade light sources.
What is the best glass for hotter climates?
A great choice for hotter, sunnier climates, SunResist features advanced, triple-coated glass that is suitable for all climates and blocks more than 90% of UV rays, a greater percentage than other Low-E glass options.
How does low E glass work?
Low-E or “low-emissivity” glass is achieved by applying one or more extremely thin layers of metallic particles to the glass, allowing it to act like a sieve: Long wavelengths, or heat, are filtered out, while short wavelengths (the visible light spectrum) are allowed to pass through. By changing the types of particles used in the layers of Low-E, ...
What is heat save?
HeatSave™ interior Low-E coatingreflects heat back into the home. It’s used in combination with other energy-efficient glasses to increase heat retention without sacrificing light transmittance. HeatSave™ helps maintain a more comfortable home in the coldest climates and at higher altitudes.
What does low E coating do?
On an exterior glass surface, a Low-E coating can reflect the heat of the summer sun or the cold of winter away from the home. On an interior surface, a Low-E coating reflects back the existing indoor temperature.
Is double pane glass better than single pane glass?
Double-pane glass is much more insulating than single-pane; triple-pane is even better. Insulation is also improved with the addition of argon or krypton gas in the sealed space between the panes of glass. Multiple glass panes allow for multiple surfaces to receive Low-E coatings, depending on performance needs.
Does lead go on the clear side?
Should make no difference, when we have a leaded sealed unit going into plastic frames the lead generally goes on the clear side, this then has to be glazed as the outer pane so you can see the lead. No difference
Does glass make a difference?
All the energy efficient qualities of glass, when combined together do make a small difference.
