Low E & Laminated Glass

A person is looking out of the window.

Cambridge can offer to consumers, beneficial, long-lasting glass windows that will effectively reduce your energy costs year-round, as well as offer your home much-needed protection from forced entry, severe weather conditions, as well as give consumers powerful sound control. Low E and laminated glass windows are created with powerful material and are engineered in specific forms, in order to provide your home with added security, comfort and peace of mind.

Below, we will present the most essential information regarding these categories of glass windows.

What is Argon?

Thermal performance of insulated glass units is accomplished by reducing the conductivity of the air between the layers. Argon is a non-toxic, clear, and odorless gas that provides extra insulation. Since argon is heavier than air rather than being in continuous motion like air, it greatly reduces the transference of heat and cold through glass window panes.

Year Round Savings, Year-Round Comfort

In the home, windows provide natural light. They also can account for up to 30 percent of the year-round energy consumed in a typical house. LoE² glass products from Cardinal IG, give you year-round energy savings and comfort by helping manage the sun's energy and the heating system in your home.

LoE² glass products are coated with microscopically thin, optically transparent layers of silver sandwiched between layers of anti-reflective metal oxide coatings. These "smart" coatings provide optimal year-round energy-saving benefits by selectively filtering the sun's energy in summer and reducing heat loss in winter. In the summer, LoE² glass products let in visible sunlight while blocking 84 percent infrared and ultraviolet solar energy that drives up cooling costs and damages curtains, window treatments, carpeting, and furnishings. And in the winter, Cardinal's LoE2 glass products offer greater comfort and reduced heating costs by reflecting room-side heat back into the room.

What You Need to Know

  • Insulating glass units are the heart of the best residential windows. These typically are two-pane sealed units incorporating a low emissivity coating and Argon filling.
  • U-Value is the amount of heat transmitted by the window. The lower the number, the more efficient the window in reducing winter heating costs.
  • R-Value designates a window's resistance to heat flow. This number is the inverse of the U-value; the higher the number, the more efficient the window in reducing winter heating costs.
  • Solar Heat Gain Coefficient is the fraction of incident solar radiation entering a home through the windows. The lower the number, the better the window is at preventing solar gain - critical to reducing summer cooling costs.

Laminated Glass

Laminated glass consists of a tough protective interlayer made of polyvinyl butyral (PVB) bonded together between two panes of glass under heat and pressure. Once sealed together, the glass "sandwich" behaves as a single unit and looks like normal glass. Annealed, heat-strengthened or tempered glass can be used to produce laminated glass. Similar to the glass in car windshields, laminated glass may crack upon impact, but the glass fragments tend to adhere to the protective interlayer rather than falling free and potentially causing injury.

Laminated glass is the only glass to provide durability, high-performance and multi-functional benefits while at the same time preserving the aesthetic appearance of the glass. Laminated glass furnishes solutions to many architectural design problems and offers increased protection from the effects of disasters such as hurricane, earthquake and bomb blast. Benefits of laminated glass include:

The toughness and resiliency of laminated glass make it an excellent safety glazing. In vertical or sloped applications, laminated glass can resist penetration from impact. If the glass is broken, fragments will adhere to the PVB, reducing the risk of personal injury and property damage.

Ultraviolet Screening

The ultraviolet (UV) filtering performance of the protective interlayer helps protect valuable furnishings, displays or merchandise from the fading effects of UV radiation.


Laminated glass offers greater protection for people and property over other glass products. The standard two-ply construction provides resistance to penetration when subjected to attempted forced entry. In multi-ply configurations, laminated glass can even resist bullets, heavy objects, or small explosions. In most cases, it takes many blows, all in the same spot, to penetrate the glass.


The PVB in the laminated glass helps reduce solar energy transmittance to reduce cooling loads.


Sound Control

The sheer damping performance of the PVB makes laminated glass an effective sound control product. Laminated glass is commonly used in airports, museums, sound studios, and schools to keep away unwanted noise from airplanes, heavy machinery, and traffic, to name a few.

Hurricane, Earthquake and Bomb Blast

Laminated glass can help protect from injury and property damage from man-made or natural disasters. By keeping the glass intact within the frame, laminated glass helps reduce injuries from large shards of flying glass.

Keepsafe Glass for Premium Protection

Peace of Mind for Your Family's HomePeace of Mind for Your Family's Home
When it comes to safety, Keepsafe® glass provides premium protection. Made with a tough plastic interlayer fused between two panes of glass, Keepsafe® technology creates an impact-resistant barrier so strong that it can withstand a direct blow from a crowbar!

Other benefits of the Keepsafe® system include:

  • Safety: After impact, glass remains intact. This prevents accidental injury caused by hazardous shards of glass.
  • Sound Reduction: The noise of traffic, airplanes and lawn mowers is reduced by as much as 50%.
  • Solar Protection: Ultraviolet rays of the sun are absorbed which protects furnishings from premature fading.
  • Value: Not only does this state-of-the-art technology enhance property value, but it may also save insurance costs by reducing premiums.
