Lumber shrinks after being dried and treated. For example, a standard 2 x 4 is actually one and a half to three and a half inches. Lumber is sold in grades and you may not need the highest quality wood for your project. Handy homeowners like to do some remodeling themselves on floors and walls. Sheet rock is a commonly used wall material and comes in different sizes to suit your needs.
Paneling can be sheets of solid wood, plywood, or fiber board.
Solid wood is the most expensive and the best quality. If you're doing a ceiling, you'll probably use wood, metal, or plaster. Fiber and fiberglass tiles will cut down the noise. When doing a floor the most common building materials used are wood, carpeting, and ceramic tiles. In choosing a floor, you should pay careful attention to what the room will be used for.
