Our copper is .005 thick and can be cut with standard scissors, yet is quite durable. If you took alumium foil and folded it approx. 5 times this will give you an idea of the thickness of the copper. It's much heavier than a foil with a 3' x 4' sheet weighing almost 3 lbs. It is 110 Annealed Copper which means its pure and soft. It's easy to fold and can be glued with either contact cement or glues which can be spread on wood and pressure applied using a roller and/or a vacuum compressor and bag.
