Why Low-E

Of all the options and accessories to consider for your windows, the most important is really the most obvious, the glass. Accounting for up to 80% of a window’s real-estate, glass can make or break the overall performance of your window system.

What exactly is Low-E glass technology? Low-E glass filters the sun’s long-wave UV radiation. This reduces the summer’s solar heat gain from the sun, maintaining a lower average temperature in your home. Low-E glass insulation works differently in the winter months. Keeping the cool air out, the glass traps heated air within the home.

Keeps the Heat Inside

Both Low E options will significantly reduce the amount of heat lost through your windows to help save on your heating energy costs. Lower U-values and higher R-values are an indication of greater performing windows.

Controls Solar Energy

The most unique attribute between our two Low-E offerings is the Solar Heat Gain Coefficient or the amount of solar heat gain relative to the incident solar radiation. Higher SHGC numbers provide natural energy in the winter to reduce heating costs, while lower numbers block heat gain in the summer.

Clear Appearance

Visible Light Transmittance is the percentage of visible light that passes through a glass product. Durabuilt’s Low E glass solutions are highly transparent providing an aesthetically pleasing interior / exterior appearance similar to clear glass.

Fade Protection

Shading Coefficient is the ratio of total solar energy that passes through, relative to standard clear glass. Low E coatings block damaging ultraviolet (UV) rays to help protect your fabrics, furniture and carpets from fading.
