Just wanting to learn more about alternative insulation products compared to foams and fiberglass.  There is small amount of info out there about wood fiber insulation, and I am excited to see what becomes of GO labs, an up and coming wood fiber manufacturer out of Maine. And I’m very familiar with Rockwool and obviously like it better than fiberglass and most foams, but still see the possibility of other products (wood fiber, hemp, or wool) performing similarly and having a carbon neutral or negative impact.
Anyone have experience with using sheep wool insulation of any kind (batt or loose fill), and/or have any insight into the performance? I’ve seen in on various social media platforms being used in campervan build outs, mostly sourced from Havelock Wool, and know that 475 supplies it. Most of the time I see it in pictures, the batts seem to be installed in varied depth and fluff, which seems negative, given you usually want an consistent installation depth and fluff of whatever insulation you choose. Or is that not the case when it comes to sheep wool?
Similarly in regards to Hemp fiber insulation, does anyone have experience or performance insights? It seems like Hempitecture is one brand making batt and loose fill hemp fiber insulation out of Ketchum, ID. Are there others making hemp fiber insulation? Thanks
