Components of drywall

Answer 1

Drywall hammer, tape measure, drywall rasp, metal cutters (straight cut), pencil (never use a pen), razor knife, pipehole knocker (preferably copper pipe), chalkline, T-square, router (optional), screwgun, drywall horse, kicker bar (for jacking up bottom sheets on the walls), and a good partner than can pull his own weight.

Answer 2

It depends on where the wall is and it's purpose. Many interior walls in homes contain only 2 x 4 wood framing. Some will have insulation for warmth and soundproofing reasons. If it's a 'separation wall' in an apartment building it will likely be a 2 x 6 frame with fire -rated insulation. Many walls in modern buildings have metal framing instead of wood .

Answer 3

I don't know whether it's an "element" , but calcium sulfate dihydrate is the main material in drywall.
