SpyGuard
From Wikipedia, the free encyclopedia
SpyGuard™ is a material used to protect glass windows from being spied on, a product made by GlassLock.
[edit] How it works
SpyGuard has an appearance like Clingfilm which is placed in between two window panes which protects from radio frequency signals entering or exiting the protected room via the windows. Various levels of security are available; only the most basic is available to US and UK customers without high level security connections.
