False Ceiling 

Misleading roofs, otherwise called false ceilings, contrast from false ceilings as they drape nearer to the ground underneath the first roof structure. There is typically a space between the first roof and the misleading roof, which can be valuable for sound sealing condos in a similar structure.


False ceilings are usually constructed from steel tiles and suspended from the framing joists in roofs. Because there is a gap between the ceiling of one apartment and the floor of another, noise is significantly dampened as it needs to travel through the gap in the ceilings. Some false ceilings are made from acoustical tiles, which restrict sound transmission further by absorbing sounds that pass through a false ceiling.


The false ceiling structure is hung from resilient metal wires below the original ceiling. A false ceiling usually hangs a few inches from the roof but some lie as much as a foot below the original false ceiling structure. The steel tile structure of false ceilings is usually supported by a grid of metal frames that run across the breadth of the room. Molding is then connected to the wall across the same room space. The rest of the grid is supported by hanging wires, which gain additional support from the molding on the walls.

Acoustical Ratings for false ceilings

Two unique appraisals measure the soundproofing capacities of specific roof tile materials. The Noise Reduction Coefficient, which goes from 0 to 1.0, demonstrates how much sound the material ingests; an NRC of 0 implies that the tile mirrors every one of the sounds that hit it back into the room, and an NRC of 1.0 implies that the tile retains each of the sounds that hit. The false ceiling Attenuation Class estimates how well the roof tile forestalls the transmission of sound through the tile; the CAC is the more significant rating assuming you're worried about sound going through the roof to the room above. A tile with a CAC more prominent than 35 is viewed as superior execution as far as its outside noise-canceling abilities, and among roof tile materials, mineral fiber tiles will generally have higher CAC evaluations.


For sound to pass from one side of your roof to different, vibrations should have the option to go through the roof. Vibrations move effectively when there's a ceaseless actual way for them to travel through, so one of the major ways of soundproofing a roof is to "decouple" one side of the roof from the other, implying that the roof material in the room beneath isn't straightforwardly associated with the floor of the room above. Since false ceilings are ordinarily developed with roof tiles suspended in a casing underneath the roof joists and the subfloor of the room over, the plan of a drop roof naturally offers work in decoupling and the initial move toward soundproofing.

Adding Mass

Sound transmission through the roof likewise expects that the roof material has the option to vibrate so it can pass the sound vibration to the space above it. One method for diminishing a roof tile's capacity to vibrate is to build its mass so that it's impervious to the vibrating energy of the sound that hits it. A few makers offer sound-lessening items, either thick plates that sit on top of roof tiles or extraordinarily planned thick tiles, that expand the mass of the roof and make it particularly impervious to vibration.

Engrossing Sound

Regardless of whether there is no immediate association between the drop roof and the floor above it, sound that figures out how to go through the roof tile will, in any case, make the air in the space between the roof and the floor above vibrate, and that vibration can pass sound to the room above. Occupying the space with a sound-engrossing material, for example, fiberglass protection will assist with retaining the vibration hold it back from passing to the floor above. Protection will not, nonetheless, offer as a very remarkable soundproofing impact as decoupling or adding mass.

Apparatuses and Mechanical Systems

Ventilation work, light apparatuses, vents, and other mechanical frameworks inside a drop roof can fill in as a pathway for sound through the roof. Noise-canceling covers over light apparatuses and air returns can assist with keeping sound from going around and through the installations. Sound-damping paint or coatings inside ventilation work assists with preventing the conduits from vibrating, and acoustical bewilders inside pipes can assist with holding sound back from traveling through the air inside the channel.

Advantages of false ceiling

1. It is very easy to install false ceilings with the help of the right kind of tools. Although you can install it by yourself, it is advisable to get it installed by a professional contractor.

2. A false ceiling hides the ductwork, pipes, and electrical wires giving the ceiling a clutter-free neat, and clean look.

3. It is easy to reassemble the panels of a false ceiling in case of repair works.

4. A false ceiling plays a key role in acoustics and sound absorption. It is designed in such a way that it adds to noise reduction thus, making the space quiet

5. It is much more economical to install a false ceiling than to get the entire ceiling renovated in case of damages as they are removable.
