High Tech Glazing


EuroLite Advanced IGU’s

EuroLite’s advanced frame construction deserves only the best glass technology. EuroLite is proud to use Saint-Gobain glass in all our windows and doors. Saint-Gobain is renowned for creating the famous Hall of Mirrors at Versailles in the 17th century and has remained at the forefront of float glass technology for 350 years.

Pre-Installed Glazing

Some companies require you to install glazing on site – creating an increased risk of damage or error, and increased cost. The glazing on all our doors and windows is installed at our factory in a controlled environment, eliminating the possibility of error or damage

Your EuroLite project manager will help you decide the best glazing choices for your situation and climate.

IGU Construction Types

Clear and distortion free glass lets you enjoy the views you have chosen. You can feel visually connected with the outside while being protected from heat, cold, rain, snow, wind - and noise.

Depending on your climate needs and the placement of each fenestration, we will use one of three types of IGU construction, as well as one of three combinations of glass types - a total of 9 different options. This customized construction means your EuroLite project manager will be able to tailor every window and door to suit your exact needs.


Transparency Choices


Our IGU’s are built using Saint-Gobain’s distortion free, water clear ‘Planilux’, and ‘Planitherm’, a 92% clarity, super efficient, Low-E glass. In hot climates we can also choose from two levels of ‘Cool-Lite’ Solar Control glass. By utilizing different combinations of high tech glass, we are able to create superb, custom solutions for every climate zone and situation.

With total window U-Factors as low as 0.18 - there is no better window construction available.

Lowest U-Factor

High Tech glass, special coatings, krypton gas fill and warm edge spacers are integrated into our thermally broken steel frames to give you the best combination of energy savings, comfort and aesthetic appeal.

Krypton Gas - clearly better

EuroLite is the only manufacturer to provide krypton gas filled IGUs (Insulated Glass Units) as standard.

Krypton is a significantly better insulator than argon, which means our dual pane IGU’s work as well as triple pane argon filled units. Even when triple pane glass is required, krypton lets us build slimmer and trimmer IGUs, in keeping with our minimalist style. EuroLite triple pane units are only 1” thick


Divided Lites

The look of multiple separated panes of glass in a window is popular in a wide variety of architectural styles. They can be diamond shaped as in historical replications, or squares as in traditional and modern homes. For those who seek historical accuracy, true divided lites (TDL) are truly separated individual glass panes in a single window. Simulated divided lites, (SDL) mimic the look of individual panes of glass in a window, without sacrificing the energy efficiency of a single pane of glass. SDLs are available in a two different styles, either with or without a spacer bar inside the two panes of glass.

  • TDL - True divided lite (also referred to as Authentic divided lite) windows consist of multiple panes of glass physically separated by *muntins.
  • SDL - Simulated Divided Lite windows have just one piece of glass with muntins attached to both the interior and exterior of the glass.
  • SDL with Spacer – Simulated Divided Lite paired with a spacer bar installed between the glass creates an even closer match to the True Divided Lite.
  • Windows and doors with one lite perform the best for the NFRC thermal ratings. Thermal performance can be lowered by selecting either the TDL or SDL with spacer bars.

About R-Value & U-Factor

R-Value is a measurement of the insulating property of a single material, like a sheet of glass, wood or fiber insulation. The higher the R-Value, the better is the insulation.

U-Factor is the measurement of heat loss through a complex assembly, like a door or window unit. It is calculated using the R-Values of all the layers of the structure. It is essentially the reciprocal of the average R-Value for the whole unit. The lower the U-Factor, the better the insulation.

In the United States, U-Factors are expressed as British thermal units (Btu) per hour-square feet-degrees Fahrenheit - Btu/(h⋅ft2⋅°F). International U-Factors are expressed in SI units, as Watts per square meter-Kelvin - W/(m2⋅K). You can convert international units to US customary units by dividing the SI unit by 5.678.

About Low-E, SHGT and VT

Emissivity is a measurement of how well a surface can emit thermal radiation. This radiation may include both visible light and infrared, which is invisible to human eyes.

Low-E stands for Low Emissivity and is a type of glass that has a special coating to reduce the emissivity of the glass surface.

SHGC stands for Solar Heat Gain Coefficient and is a measurement of a window’s ability to transmit solar energy into a room. The higher the SHGC, the more the sun’s energy can contribute to passive heating. Put another way, a lower SHGC will reduce solar heating and save on air conditioning costs.

Visible Light Transmittance (VT) is a measurement of the total amount of visible light a window allows into the home.

Condensation Resistance

Condensation between two panes of glass is usually caused by a defect in the seals that hold the insulating gas between the window panes, or improper installation. If you’ve purchased new windows, such a defect is usually noticed right away and would be covered under the company’s warranty. To prevent such defects from happening, the NFRC establishes standards of 'Condensation Resistance’ that ascertain how well a window resists the formation of condensation on the inside surface of the glass. All EuroLite windows have specially designed, integral seals that are engineered to prevent condensation for the lifetime of your windows. EuroLite dual pane steel windows exceed the NFRC 500 standards for condensation resistance.
