Shielding windows and outdoor areas

There are many types of aluminium insect screen-I found this one useful in front of windows.

It is effective against wifi,2G,3G,4G,Smartmeters- while at the same time letting light into your room.

While it does not give satisfactory protection towards more focused radiation,

I have found it to reduce the impact from full-on hits.

Do your research before buying.

Mesh size is of importance.
