I'm about to start building backer boxes for my electrical outlets, switches and can lights and I've gotten to thinking about the 25 gallons of green glue sitting in the corner of the basement...
I think I understand the principles of CLD fairly well but when I envision 2 small pieces of 1/2" OSB (or cement board, or whatever) fastened together with several screws, how is this NOT behaving like a single layer?
Simply g-glueing 2 layers together (without screws) makes sense to me.
Tightly fastening the 2 layers together with screws would seem to defeat the viscoelastic properties of the material between them.
Can someone fill me in on what I'm missing?
