I love learning of materials that replace traditional choices for a reduced carbon foot print or healthier interior! I'm always on the lookout for a complete gypsum board / sheet rock replacement that has the same finish qualities. Thanks for the great video Steve.
Most natural products have many useful properties beyond their insulating ones; such as not producing such dangerous fumes if they ever catch fire or not catching fire so readily, but the fundamental issue with chosing a natural product over a man-made one is that they don't insulate as well. We need architects to come up with ways to use these natural materials in ways that minimises the effect of the additional thickness that is required to match the best man-made materials.
I went to Havelock's website and that wool insulation is eye-wattering pricey. It would cost $3600 in loose fill wool to insulate 1440 sq ft (two 60x8 and two 30x8 walls) whereas cellulose from Home Depot would cost $315. Include the attic, and we are probably look at a $5000 or $6000 premium over cellulose. There are better ways to spend that money.
Not sure how you are arriving at $315 from HD. To fill that much sqft of wall for the cellulose alone is $2000. You then have to add netting and labor. The free machine for HD or Lowes does not do dense pack wall insulation. It is for attics only. Blowing insulation in a wall is an art and it not for the DIYer.
I'm allergic to wool. I'm curious whether or not this would be horrible for me given that it's enclosed in the wall. Seems like at the least the install would be no fun for me.
My understanding Steve is that t-studs are stronger structurally then dimensional lumber. I'm interested to know if there any fire retardant manufactured into this type of insulation used
Yes, with the ZIP panels, the air sealing is at the outside... in winter time, this is the coldest surface in your wall, if any warm moist air can reach the sealing tape, you get condensation which wets the OSB of those ZIP panels. In order to prevent this, you need also an air barrier at the inside (warm moisst side) which you make as vapor open as possible, i.e. sheetrock with lime or oil paint (the sheetrock also needs to be caulked at all the seams).
Always a bucket load of info.
TY Steve annnndddd the build network!
I kill me, now you want to also…. 🤣🤣🤣

nice. any idea how wool vs rock wool acts as a sound barrier

Is there a risk of the R9 zip of trapping moisture inside? I could never afford the wool but could get close with dense pack Cellulose.
