Low E Glass

Low E coatings are a major factor in the performance of a sealed unit. There are many Low E coating options. The common one are the passive low-e coatings and solar control low-e coatings.

  • Passive low-e coatings are designed to maximize solar heat gain into a home or building to create the effect of “passive” heating and reducing reliance on artificial heating.
  • Solar control low-e coatings are designed to limit the amount of solar heat that passes into a home or building for the purpose of keeping buildings cooler and reducing energy consumption related to air conditioning.

Why Use Low Emissivity Glass?

Low-E glass performs best when you precisely know the value table to help you choose the right application. It hence becomes important for the glazing contractor to provide samples. As the final product may have a different look. You can use LOW E glasses in windows, doors, curtain walls, skylights, and glass facades, providing a balance between natural light transmission and insulation. Its unique coating reflects heat back to its source, making it an ideal choice for climates with both hot summers and cold winters.

Advantages and Disadvantages


Energy Efficiency

Low-E glass significantly reduces heat transfer, minimizing energy consumption for heating and cooling purposes. It helps maintain stable indoor temperatures and reduces reliance on HVAC systems

UV Protection

The low-E coating on the glass blocks a significant amount of harmful ultraviolet (UV) rays from entering the building.

Enhanced Comfort

It helps maintain a consistent temperature, reducing hotspots and improving occupant comfort throughout the year.

Natural Light Transmission

Despite its insulating properties, low-E glass allows ample natural light to enter the building, creating a bright and welcoming atmosphere.

Environmental Sustainability

By improving energy efficiency, low-E glass contributes to environmental sustainability efforts. Reduced energy consumption means lower greenhouse gas emissions.


Higher Cost

Low-E glass tends to be more expensive than standard glass due to the additional coating and manufacturing processes involved.

Limited Solar Heat Gain

While low-E glass blocks a significant amount of heat, it also restricts solar heat gain.

Coating Vulnerability

The low-E coating on the glass can be delicate and susceptible to damage during handling, installation, or cleaning.

Visible Light Reflection

In some cases, low-E glass may have a slight tint or reflectivity, which can affect the visual appearance from both the inside and outside of the building.

Specialized Installation

Low-E glass often requires specialized installation techniques to ensure proper performance and maintain warranties.
