So the shiny surface facing down works fine because the heat absorbed by the roofing material is not easily emitted or transferred to the attic space.

Does radiant barrier foil really work?

A radiant barrier reduces the radiant heat transfer from the underside of the roof to the other surfaces in the attic.

In order to prevent moisture issues, it’s imperative to use perforated radiant barriers.

Does foil insulation affect WIFI?

Some construction materials are well-known to mess around with wireless signal strength. The foil does a little bit to help reflect heat, but it does a lot to effectively kill the transmittance of cellular or wifi signals throughout your home. It can even block signals between adjacent rooms.
