R Value of loose fill asbestos...

Does ANYONE know the R value per inch for loose fill asbestos insulation?



Don't worry. I have no intentions of disturbing it. I just need to know in order to do a heat loss calculation.



I looked on Google, and all they did was warn me not to disturb it.



It is similar in consistency to mineral wool, and if I can't find a true R value, I will assume the R value of mineral wool loose fill insulation.



Mucho Gratzi.

  • It's between

    R-4 and R-11.
    Often wrong, never in doubt.

    Thanks Alan...

    I will assume the median.

    R Value for asbestos

    This is what I found during a quick search "I tried the search term "Thermal Conductivity of Asbestos" and got this page (http://www.engineeringtoolbox.com/thermal-conductivity-d_429.html) for the 1st hit. After a few unit conversions, I came up with an R-value for asbestos mill board of 12.4 per inch of thickness. Loose packed asbestos came in at 11.8 per inch."

    Hope it helps

    Thanks Rob...

    I will take it into consideration.



    Funny how a slight change in syntax makes a World of difference :-)
