Hulstrunk’s 100 Year Envelope
I am building a single story addition with a vented cathedral ceiling. I will be using double stud walls, parallel chord trusses and dense pack cellulose. I would like to avoid the use of foam.
I am wondering if any builders are using Bill Hulstrunk’s 100-year envelope design.
It appears to have the advantages of an exterior air barrier (where possible) and an interior air barrier to accommodate for the roof venting. Does anybody out there have thoughts on this design?
