What is LoE3 glass?

LoE3, or low-emission cubed, is a virtually invisible metallic oxide layer placed on the surface of the skylight to reduce its U-factor by subduing radiative heat flow through the skylight. Even on cloudy days, 80 percent of UV radiation makes its way past the cloud cover.

What is Low-E 2 glass?

Low E, or Low-Emissivity, glass is a type of glazing glass containing a transparent, microscopic coating that improves the thermal efficiency of your windows.

What does Low-E 366 glass mean?

LoĒ³-366 adds a third layer of silver coating. Result: a clear coating that blocks even more solar gain, reflects heat, and lets the light stream in. LoĒ³-366 actually outperforms the tinted glass often used in warm climates.

What is tempered low E3 glass?

Low-E3 windows are another industry term that simply reflects the application of three coats of metal onto a window. This style of window tends to be a great all climate window because it offers great performance in colder weather (U-Factor) and enhanced performance in summer (SHGC).

What does 366 mean in glass?

Low-E 366. The ultimate performance glass, Low-E 366 provides the highest levels of year-round comfort and greatest energy savings. Its patented coating offers an ideal balance of solar control and high visibility. Blocking up to 95% of the sun's damaging rays, Low-E 366 glass sets a new standard in energy performance.

What Are Low-E Coatings For Windows?

Are there different grades of low-e glass?

There are two types of Low E coatings - Hard Coat Low E and Soft Coat Low E. A hard-coat Low E glass is a version of the coating which is applied to the glass when it is just coming out of the furnace. The coating is fused onto the glass as it cools down.

What is low-e 272 glass?

The patented Low Ē²-272 coating provides high performance solar control and visual clarity. The end result of all this engineering is that Low Ē²-272 provides the ultimate in comfort because it reduces window heat gain by 50% or more when compared to ordinary glass.

Which is better tempered or Low-E glass?

Tempered glass windows are stronger and more resistant to breakage. When they do break, the glass crumbles into tiny, rounded pieces rather than long shards.

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!

Is Low-E glass better than double glazing?

As a general rule, low-E glass (especially tinted low-E glass) is most effective in areas where sunlight enters the home directly, while double glazing is more effective in areas where heat transfer occurs via the surrounding atmosphere.

Does Low-E glass look darker?

Low E glass contains layers of silver nitrate (depending on which type is used) that are molecularly bonded to the glass. Low E glass is slightly darker (lower visible light transmittance) than clear glass, but not by much.

Does Low-E glass have a green tint?

Building code requires that replacement windows include Low-E glass, which is very efficient at blocking solar heat and reducing damage from UV light. Unfortunately, Low-E glass provides a blue/green coloration to the glass that many homeowners find unattractive.

Does Low-E glass work in the shade?

It works by blocking certain wavelengths of light but allowing others through. The sun's light comes in a few forms and they each have a unique range of wavelengths. Low-E glass attempts to block high amounts of UV and IR light while allowing as much Visible Light in as possible.

Does Low-E glass help in winter?

If you live in an extremely cold climate, the hard-coat Low-E glass may be an option for you, because it allows some of the sun's short-wave infrared energy to pass through the glass. This helps to heat your home in the winter and allows the glass to reflect the interior long-wave heat energy back inside.

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 glass keep heat out?

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.

Can you use Windex on Low-E windows?

Cleaning Low E Glass

Consequently it is recommended that Windex® glass and surface cleaner (clear liquid) is used as this will minimise smearing. Do not use ammonia based glass cleaners or alcohol based cleaners, as these will leave smears on the glass.

How can I tell if my windows are Low-E glass?

How do you clean Low-E glass?

A mixture of one part vinegar with ten parts water Vinegar based glass cleaners have generally demonstrated an ability to provide a clean and streak free glass surface. Do not use ammonia based or alcohol based glass cleaners because these cleaners tend to leave visible streaks.

Is Low-E glass easy to break?

Improved safety: Like most types of glass, laminated glass can crack or break in instances of extreme impact. However, the glass won't shatter and break into shards that could injure someone.

What is the most energy efficient glass?

Energy-Efficient Glass

With dual-pane or triple-pane glass, inert argon gas can be used between panes of glass to improve insulating properties. Laminated, tempered, tinted and obscure insulating glass can also add ultraviolet protection to help keep your home more comfortable and energy efficient.

Is Low-E glass the same as tempered glass?

If it is made using tempered glass, the sheet may fall out of the frame but will still stay together. Low-Emissivity Glass – low-emissivity (Low-E) glass has a special coating that reflects infrared radiation (heat) while still allowing light from the visible spectrum to pass through.

What is the difference between low E 180 272 glass?

LoE-180 has 80% visible light transmittance, LoE-272 has 72% visible light transmittance. Clear glass (3.0mm / 3.0mm - not coated) dual pane has a visible light transmittance of 82%. 2. LoE-272 is more reflective than is LoE-180.

Does PGT use Cardinal Glass?

PGT, which manufactures and supplies residential impact-resistant windows and doors, sold to Cardinal Glass the assets that PGT has used in processing glass components for doors.
