Answer to Question 1

Vapor barriers can be asphalt impregnated paper, aluminum-coated wood or paper products, or
polyethylene film.



Answer to Question 2

Plywood is classified with a letter from A to D. The higher the letter, the better the grade. Grade A is
smooth and paintable; a grade D has knots and knotholes.
