Certainly non-conductive materials!

In the past we have mounted gyros and accelerometers with screws and nuts onto a thin (<1/16") metal plate, with a thin (1/8") piece of hobby foam sandwiched underneath. The screws were not too tight (so the solder points below didn't punch through the foam), then we used blue thread-locker to make sure it stayed. The metal plates were then mounted to the robot frame as necessary.
