Low-emissivity windows are great if you want to boost energy efficiency in the home because they limit the amount of solar heat that gets inside a property, helping keep passive heating at bay. However, there are concerns about low-E windows melting vinyl siding. Window replacement expert Renewal by Andersen of Denver is here to shed some light on the potential problem.
When barometric pressure between the interior and exterior panes of a double-glazed window differ, it turns the window slightly concave. This magnifies and focuses the light reflecting off a window, resulting in a beam with temperatures up to 200 degrees Fahrenheit, according to some accounts. This temperature is enough to melt plastic products like vinyl siding.
What You Can Do About It
The issue is still not completely understood and just a handful of cases of vinyl siding being melted have been reported so it’s highly unlikely you’ll end up a culprit after buying low-E replacement windows. However, if you are still worried about, you can err on the side of caution and take measures to avoid it altogether, like:
Not installing low-E windows on a home that is less than 20 feet away from another property with vinyl siding
Adding an arbor or some other shading to your home to protect your neighbors from your windows’ glare
Using shades and awnings at your window to minimize window glass reflections
