Does Emf Radiation Penatrate Metal Siding

They prevent beneficial energies coming from outside from entering the home.
Does emf radiation penatrate metal siding. In fact it will penetrate anything brick metal concrete and you without any trouble. Another common material for constructing homes and commercial properties is brick. This can cause high levels of electric and magnetic radiation in a house possibly even shocking the people living there. Penetration depth is a measure of how deep light or any electromagnetic radiation can penetrate into a material.
It is very difficult to isolate all metal electrical boxes from the metal siding but if that can be successfully done then it is not a problem from an emf standpoint. Copper conducts best but aluminum almost as well and steel a little less. I have neither tested or used the emf underlayments. Metal is fantastic for shielding purposes.
Frequently asked questions about electromagnetic shielding. Air ducts and siding made of metal. Metals do have an odor to them especially raw plates of steel and aluminum. Electromagnetic radiation can be blocked by any conducting material as the free electrons moving in the material adjust to neutralize the field see wikipedia faraday cage or faraday shield.
Aluminum foil and ordinary aluminum window screens make good radiation shields. It is defined as the depth at which the intensity of the radiation inside the material falls to 1 e about 37 of its original value at or more properly just beneath the surface. Does brick block emf. Therefore you are only protected if there is a material capable of blocking the radiation directly between you and the source of the radiation.
A thick brick wall will stop most of it a metal sheet will stop it completely. The tests used one to three bricks and the results show that bricks were less effective in blocking emfs at a lower frequency. Nothing blocks low frequency emf. Just ask anyone that has put a metal roof on their home and tries to get a cell phone signal.
I suspect they are effective but there are a great many other benefits to metal roofing here. A 95 enclosure will still allow electro magnetic radiation to get in provided that the opening is larger than the wavelength of the radiation. Rf and microwave emf radiation travel in straight lines. We are simply showing that skin is a good absorber of microwave radiation and that very little of ambient level microwaves.
There are more subtle reasons for not having metal roofing or siding particularly aluminum siding. However you do need to remember that although aluminum does block emf radiation it does not absorb it. An ideal faraday cage is enclosed in metal conductive material on all 6 sides including the floor.
