How to make sound insulation of the ceiling in the apartment - the best materials and installation methods

ceiling - one of the main "culprits" ingress noise in the apartment.You can set the thick door, five-chamber windows, to sheathe the walls of plasterboard, but if you do not soundproof the ceiling in the apartment is not really easy.

materials for sound insulation of the ceiling will need a material that has good noise-suppressing properties, but rather thin, non-flammable and does not emit toxic substances.In this role fit:

• mineral wool,
• foam,
• polyurethane foam plates,
• coconut leaf,
• cork.

Each of them has its own advantages.For example, mineral wool is not deformed and does not change the size and reduces the transmission of noise by 90%, and foam from the polyurethane foam is easier to install and better protection against impact noise.If done right, the ceiling insulation noise level in the room is reduced by 20-25 dB.

Using a noise insulation material means any arrangement of the ceiling.Noise insulating layer can be covered with drywall or stretch ceiling.

Preparations

For jobs require standard tools and accessories, ladder or wood.It requires minimal training ceiling: it must be clean and relatively smooth.You can optionally primed the ceiling: he will not raise dust and adhesion using the adhesive will be higher.If the ceiling has a gap or crack, they sealed antivibration sealant.Consider the best materials for sound insulation and the characteristics of their installation.

foam

One of the easiest and fastest ways to soundproof the ceiling is pasting the ceiling surface of the foam sheet.This will require only glue or universal foam, and the foam 2-3 mm thick.Technology gluing foam is the same as for decorative plates from expanded polystyrene (read about it here), with the only difference that the fitting joints may be not so well - they will still be hidden plasterboard or vinyl canvas.

cork stoppers

advantage is its environmental friendliness and ability to breathe.The microclimate in the apartment does not change, and the noise level will decrease.Due to the small thickness of the tubes, the ceiling height is reduced slightly.A layer of cork soundproofing drywall normally closed or left in an unusual interior solutions.The main disadvantage - the high cost of congestion and the need to use special glue not cheap, because of the usual tube is deformed.

Mineral wool

When using mineral wool as insulation initially attached to the ceiling profile.Between him and the wall around the perimeter of the tape is laid damper to absorb the vibration.The distance between the rails should be 2-3 mm less than the width of the roll, the material fills the entire space without gaps.In future this can be used to fasten the plasterboard profile in the usual way.In fact, a standard suspended ceiling, interior space of which is filled with mineral wool.Particular attention should be paid to ensuring that all voids were filled with sound-insulating material, or they will serve as resonators, amplifying the noise.

Acoustic ceiling

Installing acoustic ceiling makes sense if the noise level is high from the top, for example, there is located commercial premises, or in the apartment already made repairs.The main disadvantage is that it takes 15-18 cm from the height of the room, so it is recommended for ceiling height of not less than 250 cm.

whole construction is a combination of an acoustic ceiling, for example, "Ecophon", and a layer of mineral wool, which is locatedbetween it and the floor slab.Maximum sound insulation can be achieved by combining several materials, for example, pasted on the ceiling or a foam plug and positioning the mineral wool layer below.

noise insulation of the ceiling alone will be sufficient only in brick or panel house.The prefabricated and monolithic houses sounds spread on the walls, and for effective protection against noise must be soundproof walls and floor (read about it here).
