Glazing Information

With thousands of different glazing options on the market, it can often be difficult to determine the correct choice. Solar Innovations® offers a wide variety of glass options to meet the many different needs of both residential and commercial applications. Tinted and LowE glass are ideal for reducing solar heat gain, which is a must when a room will be used by people. However, when growing plants is a room’s main function, clear glass is the most beneficial. Dynamic, self-tinting glass will adjust automatically according to the sun and can assist with achieving LEED status. Argon or krypton gases can be added to any window system for increased insulation. EZ clean glazing can also be applied which will reduce your window’s maintenance requirements. For all of our windows, we offer several decorative glass options for further customization.

Tempered glass is strengthened through heat and is less prone to breaking than traditional glass so it is used in Solar’s doors, windows, and walls. When tempered glass does break, it shatters into small squares and collapses, making it safer than other choices that will break into sharp, jagged pieces. Laminated glass is used in ceiling or other potential impact applications. Upon impact, laminated will break into a spiral, but it will not fall out of the frame; laminated glass also removes 99% of all harmful UV rays.

Units can include single or double pane glazing. Single, monolithic glass is not insulated, therefore it is only recommended for interior applications, such as a folding glass wall. Insulated, double pane glass consists of two pieces of glass with an air space between; air will have to travel through both panes of glass to reach the inside. Insulated glass is commonly found in all new windows.

Tinted Glass

There are several tinting options for the glass within your insulated or monolithic window. Blue, green, grey, bronze, purple, and red color tints are available. Grey and bronze color tints are used for privacy and controlling light.

Low emission (LowE) glass is used to control light and solar heat gain in a room. LowE includes a patented coating that allows daylight to pass through the window while filtering out solar heat. The LowE option has a slight, barely visible coating that is applied to the glass and delivers year-round comfort while maintaining indoor temperatures. Our standard LowE coating options include:

Loe 272

LoE 272 glass delivers year-round comfort, whether it’s -20°F or 110°F in the shade. In winter, LoE 272 reflects heat back into the room. In summer, it rejects the sun’s heat and damaging UV rays. LoE 272 is the most common glazing used by Solar Innovations® Architectural Glazing Systems.

Loe 340

The solar performance of LoĒ³-340 glass is unprecedented in a double-pane unit with no room darkening tint required. With its SHGC of just 0.18, it greatly reduces oppressive solar heat gain, and wherever glare is a problem, LoĒ³-340 controls that as well. Then when cold weather rolls around, its low U-Factor reduces indoor heat loss resulting in year round comfort.

Loe 366

For years, LoE has been setting the standard for energy-efficient glass with a patented, state-of-the-art sputter coating process that is unmatched. LoE 366 adds a third layer of silver coating. The result: a clear coating that blocks the heat in the summer while insulating in winter. Because more visible light is allowed to enter, an additional amount of glare may occur.

LoE 180

When the weather turns frigid, LoĒ-180 glass is the perfect cold remedy. It keeps homes warmer and more comfortable by blocking heat loss to the outside and letting the sun’s heat stream in. LoE 180 is an obvious choice for projects that are attempting to generate solar heat gain from their glazing.

Electrochromic Glass

Electrochromic glass is a self-tinting glass that changes from transparent to opaque by passing low voltage electricity through the pane either manually or automatically using a control system. When connected to a control system, the glass will automatically tint to adapt to the changing sun intensity. Electrochromic glass can maintain levels of 4%, 20%, 40%, and 60% visible light transmittance (Tvis); even in the fully-tinted state of 4% Tvis, users will be able to see clearly through the window.

Automated electrochromic glass can be designed with different zones that can be independently controlled. For example, the roof can be set to 4% Tvis, while the walls are set to 40% Tvis.

Thermochromic Glass

Thermochromic glazing is a self-tinting window technology that darkens gradually and dynamically when heated by direct sunlight. Thermochromic glass lightens and darkens by itself with absolutely no mechanical intervention or electrical wires, according to changing levels of ambient temperature and sunlight.

Thermochromic glazing preserves your window’s view by reducing the need for shades, blinds, exterior overhangs and other light-blocking devices. Self-tinting windows help manage your building’s changing needs for passive solar heat gain, solar control and natural daylight transmittance.


Polycarbonate is over three times more effective at insulating a structure when it is filled with Lumira®. Lumira® Aerogel eliminates the trade-off between natural light vs. insulation by providing superior insulation that reduces heat gain, while still maintaining optimal light transmission. Energy conduction is also drastically reduced with Lumira®, which in turn saves money and increases comfort. For more information on Solar Innovations® Polycarbonate glazing click here.

Pattern Glass

Frosted and fogged patterns are added to glass through acid etching. Standard pattern glass includes: pattern 62, rain, single chip, and English reeded. Other patterns are available upon request.

Leaded Glass

Leaded glass is the addition of a leaded grid on the glass. Antique window grid work was done with leaded grids. This is a replication of the antique grids. Various configurations are available for the grids.

Blinds Between Glass

This special glass combination, where blinds are placed in the air space of an insulated glass unit, reduces strong glares and heat transmittance. The blinds are fully functional and can tilt or be pulled up/down. There are several colors available for the blinds.

Art Glass

Art glass is essentially any special order of glass. The glass can be hand-blown or machine made, contain colorful swirls, and even have an actual picture imposed onto the glass. Art glass is useful when companies are looking to have logos and other words on their windows.


Organic materials are fully encapsulated into a composite of glass and resin that is 100 times stronger than regular glass. Ensoglass can contain flowers, bamboo, grass, papyrus, leaves, and any other material you desire.

V-Groove Glass

V-groove glazing is often featured in Transoms. It is a perfect way to add aesthetic or privacy to your glass and can be used for the entire project or just for a small section.

Solera Glass

Solera glass is a completely recyclable glazing option that reduces glare and diffuses sunlight.

This glazing product includes a durable UV barrier within the glass panels that controls light and heat transmittance, creating a more energy efficient system. The UV barrier also prevents the material from becoming brittle or fading over the years, increasing the life span of the product to a range of 60 – 100 years.  Solera glass is available in several thicknesses, all of which feature a white color. For higher insulation values, Nanogel can be used to fill Solera units.

EZ Clean Glass

EZ clean technology consists of a patented coating of titanium dioxide and silicon dioxide that fills the tiny pores of the glass. Silicon dioxide makes the glass exceptionally smooth so water disperses evenly and evaporates quickly. The titanium dioxide undergoes a chemical reaction with the sun’s UV rays, causing organic materials on the glass to decompose. Then, when it rains, the decomposed dirt is washed away, leaving the glass clean and streak-free. EZ Clean Glass is recommended for sloped glazing to simplify maintenance requirements.

Altitude Limits for Insulated Glass

When a sealed insulated glass unit is constructed at low altitude, then installed at a higher altitude, the glass panes bow out because of atmospheric pressure. In extreme situations, the unit can fracture or the sealant can rupture, causing permanent damage.
