Radiant Barriers May Interfere with Cell Phone Reception.
Green Building Advisor recently published an article discussing whether radiant barriers may interfere with cell phone reception.
The conclusion? Radiant barriers and other foil-faced building products probably have some negative effect on cell phone reception, although it's most likely minor.
The article was written by Martin Holladay, one of the country's most respected experts in the field of building science and green building. After looking at statements from radiant barrier manufacturers, cell phone companies, and other building experts, he concludes:
"I’ll attempt to integrate the information I gathered into a preliminary conclusion: Foil-faced building materials can probably interfere with cell phone reception, but only in homes that have relatively weak cell phone reception to begin with. Most people who live in homes with foil-faced building materials do not have cell phone reception problems."
Have any experience with a radiant barrier interfering with cell phone reception? We'd love to hear your story.
