I am chemically sensitive. Can I use Aluminum foil to seal sources of aromatic emissions like wood moulding, cabinets, etc.?
Two issues need to be considered here. Chemically, every piece of wood is treated with pesticides at the lumberyard, to keep it marketable, even before it is coated with nice and shiny stuff like Polyurethane. Applying a seal on one surface forces the material to outgas through another surface. So unless you can completely surround the material, the aromatics will still find their way indoors. That is because walls have holes for cabling and piping, and walls, which will experience part of the aromatic outgassing, will allow passage of air, bringing the aromatics into the living space. Electrically, if the residential electric system is comprised of Romex wiring, which causes an electrified birdcage effect, every piece of conductive material has the capability to absorb part of the field and re-radiate it back, possibly making the situation much worse. If you then consider trying to ground each and every piece of foil, you run up against a technical challenge, even for the expert. • I
