How to soundproof a room with ceiling tiles

Updated April 17, 2017

Soundproofing a room can have great benefits for the rest of a house and there are many simple ways to do it. Soundproofing ceiling tiles are relatively inexpensive and are easy to fit, meaning that any noise coming from above will be muffled if not absorbed completely.

Buy soundproof or sound-absorbing ceiling tiles from a hardware store. These can vary in price, depending on their ability to dampen sound, and you should choose the tiles which best match your budget and needs.

Work out how many tiles you will need by measuring your ceiling. Ceiling tiles are usually 12 inches square, so if your room measures exactly to the foot then you will not need to cut the tiles. If your room is not a round number of feet then add 12 inches to the total leftover and divide by 2. For example, for a room measuring 6 feet 5 inches, add 5 inches to 12 and divide by 2, giving 8 1/2 inches. You will therefore need to cut two tiles to 8 1/2 inches and then use five full tiles. Adding the 12 inches prevents any tile from being less than half size.

Cut your tiles to size, making sure to take into account both width and length of the room. If your roof is smooth then you can attach the tiles with adhesive, ensuring that the cut tiles lie at the edges of the room. To test the surface, attach one line of tiles across the room and wait for 48 hours. If all the tiles remain stuck then you can proceed with the rest.

Use a furring strip if your surface is uneven or the tiles do not remain stuck in the 48 hour period. Nail this to the ceiling and repeat until you have covered the entire ceiling. You can then proceed gluing the tiles to the ceiling.

Cut the tiles to fit them around existing objects in the room, such as piping or posts. The smoother the fit, the less sound will penetrate the room. Once you have covered the whole ceiling, your room will be considerably less vulnerable to sound.
