WHAT IS LOW-E AND CAN I SAVE MONEY BY USING PRODUCTS ACCREDITED BY IT?

low-e

Low-E glass is one of the technological marvels of today’s residential construction. The “E” is for “Emissivity” and the dictionary defines emissivity as “the relative power of a surface to emit heat by radiation.” Low-E glass works by reflecting heat back to its source. It does this by utilizing a coating of microscopically thin, optically transparent layers of silver sandwiched between layers of anti-reflective metal oxide coatings.

These “smart” coatings provide optimal year-round energy savings by filtering the suns energy in summer and reducing heat loss in winter. In the summer low-E products let in visible sunlight while blocking infrared and ultraviolet solar energy that drives up cooling costs and damages curtains, window treatments, carpeting, furnishings and art work. In winter low-E glass reflects room-side heat back into the room.

Single pane :: 26 degrees

Regular double pane insulated glass :: 35 degrees

Hard coated Low-E :: 50 degrees

Soft coat Low-E :: 62 degrees

Obviously, the closer the glass temperature is to the actual room temperature the less convection there will be near the window. Low-E glass simply works.

Larger Window Areas

Because Low-E Glass is an energy-efficient, high performance glass, architects, builders, and homeowners have the freedom to incorporate larger window and glass areas in their designs, without the resulting excessive energy costs.

A Source of Free Energy

In addition to its low U-value, Low-E Glass has a high shading coefficient. Compared to other glass products with lower shading coefficients, Low-E Glass allows more of the sun’s rays to enter a home as solar energy to be converted into usable heat in winter.
