Warming of the attic foam "for" and "against"

Foam - one of the most common heaters, fast favorite with lovers of inexpensive thermal insulation materials. The price of foam is much lower than other insulation, But the list of advantages of this foam is not limited to:

  That's good, because others lose their insulation properties when getting wet and rotting;
• low weight foam builders facilitates delivery and installation and reduces the load on the roofing system;
• low thermal conductivity (in Russian - foam hardly releases heat from the house in winter and does not let the heat from the street to the house in the summer);

• Foam - combustible material and combustion emits toxic fumes.

Someone thinks that the disadvantages of foam stronger than its advantages, and its use in the insulation of the attic is not justified. Someone trusted foam and years lived in the house warm.
The final choice - is yours!
