Here is an email forwarded from Kelly:
Thanks Kelly! As long as the insulation supports are steel they should work.
Great news! I contacted the Detroit Hardware Co. off of Woodward and W. Grand Blvd (two minute drive from WSU), and they DO have the supplies you’re asking for (except for Simpson Strong Tie Insulation Supports, but they said they do have other insulation supports available).
Also, their hours:
Saturday, 9 a.m.-3 p.m.
The Detroit Hardware Company services CSS, so they are used to these requests.
