Does anyone have experience or knowledge of injection foam from USA Insulation?

Cameron Morris | Posted in Green Products and Materials on

They specialize in injection foam for retrofit applications. Their using a phenolic based methylene-linked synthetic polymer that is poured in to a wall cavity as a semi liquid. My concern is, has there been any independent study on the foams reliability and the manufactures claims?

    Cameron,
    Identifying the components used to manufacture so-called "injection foam" is difficult.

    The best roundup of available public information on this family of products was written by GBA blogger Alex Wilson. Here is a link to his article: A Vilified Insulation Material From the 1970s Returns.

    Thank you Martin, the article was very in enlightening!
    The representative at our local Earth Day fair stated it was made from soap, did not shrink and had a very good fire rating; with a 5.1 per inch r-value. The article seems to contradict everything that was stated except for fire resistance. I specifically mentioned that I was worried about off-gassing and he replied well there is some. What he did not say is ,that it was formaldehyde. Why this would be promoted as a " green" product is beyond me.
