Are they just making it up now so people insulate the insides and outsides of their house
 
not sure about the eco label on that product, it contains nano particles. these are a billonth of a metre in size. No mask is gonna stop these fckers.

So, with alarm bells ringa dinging this is what google shows up:

[h=4]Health and environmental risks[/h] Nanotechnology's unique benefits come with unique hazards. The large surface area to mass ratio that makes nanoparticles more effective in chemical reactions could also increase the level of exposure to an organism. While this could improve the effectiveness of medications using nanoparticles, it could also increase toxicity. Also, because they can pass through biological barriers, nanoparticle drugs could pose a potent threat if unwanted particles migrate through the body.
Inhalation of nanoparticles is particularly worrisome. Several studies during the last decade have shown that exposure to airborne nanoparticles can result in significant deposition of those particles in the respiratory system. Respiratory problems have followed, as well as cardiovascular ones, including coagulation and inflammation. Given the uncertainties, some groups have advocated for a moratorium on nanotechnology research and development, but that call has not been widely taken up.


[h=4]Regulation[/h] The industry hasn't yet faced any highly publicised health or environmental problems of the kind that might have brought significant regulation or litigation. Asbestos, which bears some resemblance to nanotubes, became costly for the construction industry well after it had been believed to be safe and entered widespread use.
