How to Build an MDF Window Plug

Window plugs are square or rectangular pieces of material that fit snugly inside the window frame. The purpose of plugs is to block out light and noise in a room. They are common in homes and buildings containing recording studios. Plugs consist of a variety of materials including medium-density fiberboard, otherwise called MDF. MDF is inexpensive and available at hardware and home improvement stores. Creating the plug requires only careful measurements and cutting with a standard saw.

Tape measure
Medium-density fiberboard (MDF)
Pencil
Straight edge
Safety glasses
Dust mask
Circular saw
Drill
1/4-inch drill bit
Handle
1-inch screws
Screwdriver

Instructions

- 1
  Measure the width and the length of the widow opening carefully using a tape measure to determine the size plug required.
- 2
  Lay a sheet of MDF on a flat surface, such as the floor, and draw the dimensions of the window on it using the tape measure and a pencil. If needed, use a straight edge to ensure the sides of the outline are straight.
- 3
  Move the MDF to an outdoor location and set it on saw horses. Don safety glasses and a dust mask, since MDF creates massive amounts of dust when you cut it.
- 4
  Plug in a circular saw and cut along each of the pencil lines to cut the plug portion out.
- 5
  Divide the width of the plug in half to locate the center portion of it. Mark the center with a pencil.
- 6
  Place a metal handle on middle of the pencil mark and draw pencil lines at each of the screw holes. You may need to angle the handle back slightly to see the holes, since most attach from the bottom.
- 7
  Insert a 1/4-inch drill bit into a drill and create a hole in each location that penetrates all the way through the MDF.
- 8
  Lift the MDF plug up on its side and align the handle with the screw holes. Insert the screws through the opposite side of the MDF and hand-tighten them. Finish tightening them using a screw driver until the handle no longer moves.
- 9
  Pick up the MDF plug and insert it into the desired widow opening. When you are ready to remove it, simply grasp the handle and pull outward away from the window.
