You Can Now Comment on the Spray Foam Attic Article

Sorry

My website host (Hubspot) had a problem when I published my last article, High Humidity in a Spray Foam Attic, Part 2. If you wanted to comment and were not allowed, that problem has been fixed. I apologize for the inconvenience.

  1. I am new to the world of foam
    I am new to the world of foam but used it to hopefully solve my 12″ cathedral ceiling problem which was leaking due to venting and insulation problems in such a small space. Our Northern Ontario -35 nights don’t help. I filled the roof with 10″ of foam with no air space.

    When I read in the article and came to the part about water vapour exiting the foam my first response was why would you use open celled foam. My city doesn’t require a vapour barrier on the closed foam as they consider the foam a barrier itself.

    Great web site applying physics and engineering to real building problems.

    thanks

  2. I have not seen any info on
    I have not seen any info on foaming Mobile Homes/Manufactured Homes. I have a double wide Mobile Home on a foundation. Can you tell me if these particular homes are able to be spray foamed?

    Thank you,
