Think Twice Before Using This Eco-Friendly Feature On Your Home
By MASIE O'TOOLE
While most energy-saving home improvements have few downsides, this might not be the case for low-e or low-emittance glass. In some locations, it can damage nearby properties.
Low-e windows cut home energy costs by reducing heat loss when it’s cold outside and keeping heat out during hotter weather, so they’re ideally suited for more extreme climates.
The danger lies in the extra light reflected by the glass. As the sun’s rays bounce off it, they can form a concentrated heat spot, strong enough to melt sidings on nearby homes.
High risk locations include windows with all-day sun, close to nearby buildings. Use normal glass in these situations and low-e glass elsewhere to enjoy the best of both worlds.
If you have issues with an existing installation, try covering the window with a non-reflecting material, fitting an awning, or adding a fence or greenery between the properties.
