  Available in a variety of sizes and styles, acoustical ceiling panels let you cover a problem ceiling without the hassle of hanging drywall or another material. The panels are also ideal for ceilings containing pipes and other structures you need to cover. Acoustical ceiling panels are available from a number of manufacturers, are inexpensive and require little maintenance. Like other building materials, you must cut acoustical ceiling panels to fit the space in which you are installing the panels.
  
  

Utility Knife

• The primary tool for cutting acoustical ceiling panels is a sharp utility knife. The knives are available at hardware, home improvement and retail superstores as well as online. Purchase an extra pack of blades, and change your knife's blade when it becomes dull. When cutting acoustical ceiling panels, hold your utility knife at a 45-degree angle to cut a smoother edge.
  
  

Ruler or Chalk Line

• Also needed to cut acoustical ceiling panels is a ruler or chalk line to ensure a straight cut. Purchase a 12-inch or longer "T-Square" or straightedge ruler. The rulers are available at hardware and home improvement stores, retail superstores and online. You can also use a chalk line to draw a straight line on the panels, but you still need a ruler to ensure a straight cut.
  
  

Template

• To speed up the cutting process, cut a piece of wood or cardboard the same size as the acoustical ceiling panel you want to install. Use this as a template, also known as a fitting board, for cutting other panels to an exact length. The template also helps to cut panels for ceilings that are an irregular size or to allow for molding you don't plan to remove from around your ceiling's edges.
