Low E Glass

What is it?

Low E glass has a coating that lowers the rate of emission, which reduces the transfer of heat through the glass.

What does it do?

Low E glass provides solar control, which contributes to a cooler house in summer and warmer house in winter, effectively providing better insulation for your home.

How does it work?

A Low E hard coating is applied to the glass during the manufacturing process. This coating decreases the amount of heat transmitted through the glass and provides solar protection.

Summer Conditions

Outside heat generated during summer months bounces off Low E glass.

Winter Conditions

Inside heat generated by heaters or air conditioning bounces back into the home.

  • Allows the flow of natural light

Summary

Low E glass assists in keeping the internal temperatures of homes more comfortable. Sometimes referred to as Smart Glass, it effectively maintains a desirable internal temperature. As the term would suggest it is quite smart how it works but Low E glass can’t do it all on it’s own. Artificial heating and cooling is still required however the addition of this type of glass reduces the reliance on these systems.

Typically heat is lost or gained through roofs, walls, floors and glass. Effective home insulation requires improvements in each area however research shows that ordinary glass is a key contributor to ineffective insulation. The installation of Low E glass can improve solar control by up to 39% compared to ordinary glass.

Heat loss  – Floor 18%, Roof 20%, Walls 14%, Glass 48%

Heat gain – Wall 8%, Roof 5%, Glass 87%
