Attics are usually used to store odds and ends that you do not need in your everyday life. If you do not have many things to store in your attic, you can convert the space into a usable room with a variety of purposes. Adding soundproof materials to the wall and floor of your attic will prevent unwanted noise from escaping the area. Soundproof your attic if you intend to play music or perform other loud activities there.
Put on a work mask and a pair of gloves before starting the soundproofing process. You will be working with materials that may be hazardous to your health if inhaled.
Fit sound insulation in the spaces between the wood beams in your attic. Cut the insulation so that it fits snugly between the beams. Usually, the insulation will stay in place without the use of nails or glue. Use care when cutting sound insulation. If the fibreglass strands or plastic fibres of the insulation get on your skin or eyes, they can cause irritation.
Measure the spaces between your attic beams to prepare for drywall installation. You must leave enough room on each beam to nail drywall to the edges. Once you have measured the spaces between the beams, cut the drywall to the proper lengths. Nail the drywall to the attic beams. Leave a small space at the bottom of the drywall. The space should be no more than an inch or two.
Nail sound foam to the drywall. You should lay the sound foam on the drywall so that there are no spaces between the foam pads. Cover the wall from the floor to the ceiling with the pads.
Spray expanding foam into the space you left at the bottom of the drywall. The expanding foam will fill in the spaces that are left over from the initial foam insulation. When the foam starts to seep from under the wall, stop spraying.
Install thick carpet onto the floor of your attic. Carpet is a natural insulator that will absorb sound from talking or instruments. Lay the carpet pad down first before putting carpet on the floor. Nail the carpet pad down, then place the carpet on top of the pad. Cut the carpet to contour to the corners of the attic.
Set sound blankets over the top of the sound foam you installed on your walls. Sound blankets will serve as the first line of defence against sound leaks. You can install the blankets by nailing the blankets to the wall or tacking them from the ceiling.
