I am starting to install my polyiso on the interior of my slanted cathedral roof assembly and am having trouble finding the studs through the 4.5" of polyiso that I have.
Things working against me:
1. not all studs are perfectly 16" OC.
2. The ceiling deck is at an angle.
3. When I place the screws in it's hard to get them into the studs or even find the studs with the angle of the ceiling.
Are there any videos or techniques that can help me find the studs...I'm at a loss here!
