Penoplex soundproofing ceiling

life of a modern inhabitant of the big city - a furious pace and a continuous series of events, bordering with stressful situations.It is clear and naturally becomes the desire to return home to stay in a comfortable environment to be in time for the coming morning as far as possible and restore their own strength, and to arrange psycho-emotional state.It would seem that can prevent, if there is proper housing, strong family with the good relations established way of life?

Unfortunately, very significant "adjustments" in the evening idyll can make neighbors, especially those living on the floor above.And it may be not "violent" youth company never stops "holidays" and fun.Very often the cause of anxiety becomes an offering of the most common family in which, in addition, there are small children.Simple design of many of our high-rise buildings are so perfect that through the overlapping clearly transmitted footsteps, fallen objects, rearrange furniture, working TV, and often - even talk of people, especially if they suddenly move to "elevated tone."

It is a natural reaction becomes the desire of owners to protect their homes as much as possible from such inconveniences.It begins search options that are easy and short-lived in the performance, not attracted serious material costs, and at the same time is efficient.Perhaps once he heard "half an ear" of the wonderful qualities of extruded polystyrene, a man driving a query into a search engine - Penoplex ceiling soundproofing - and receives an array of information that seems to confirm his expectations.But is it all clear?

What recommend some sites?

Many articles talk about how you can own, quickly and inexpensively, to get rid of noise, using Penoplex plate.But if you look closely, all these publications - as "twins."They painted Penoplex installation process on the ceiling and the promise that these measures sufficient to ensure that the noise from the upper neighbors ceased to be a cause for concern.

Indeed, if we believe it on the word and select this option to protect against noise, the process itself - is simple enough to follow, may well be will pass on their own.

• ceiling surface is cleaned of flaking plaster unstable (if any), wallpaper or bubbling of the paint coating.Ideally, it is best to get to the net slabs - on her plate extruded polystyrene will stay easier.

Apply can be spatulas, hard brushes, washes with water and other methods, the most suitable in a given situation.As a result, should get a stable clean surface.

• On the ceiling are sealed all the defects of surface cracks, cracks, dents and chips.Special attention - the joints between floor slabs - there are the most common defects.

How to eliminate defects in the surface of the ceiling?

Any ceiling decoration involves the preliminary preparation of its surface.How to spend grout between floor slabs - read in a special publication of our portal.

• To prevent the emergence and spread of mold and at the same time improve the quality of the adhesive surface of the ceiling, it is treated, preferably in two layers, special primer with antiseptic properties.

Priming is typically conducted by roller, and in hard to reach areas (in the corners) - brush.

• Once the surface is ready, it can be attached to the boards of extruded polystyrene - Penoplex.

clear geometry of the plates and the presence of special slats greatly simplify this process.To fix them to the ceiling, use one of the adhesives.It can be dry mortar specific destination - especially for expanded polystyrene or foam glue in plastic tubes that are applied with a gun.

Depending on the type of adhesive it is applied in different ways on the back of the panels.

Thus, the adhesive solution prepared from the dry mortar, laid out point-slide (pos. "A") or distributed over the surface evenly with a notched trowel (pos. "B").When using a special polymer glue is enough to put his bands on the perimeter and in addition - in the middle parallel to the long side of the panel ( "c" key.).

After gluing pause 2 ÷ 3 minutes, then cover tightly pressed against the ceiling surface in the right place.In this position plate is held in a minute - this should be enough for its initial fixing.If necessary, the duration of a clip can be slightly increased.

• Final fixing can be carried out using dyubeley- "fungi".Under that right through penoplex in floor slabs drilled corresponding holes.Typically, the standard panel mount enough 4 ÷ 5 dowels.
• So continue until complete closure across the ceiling plane.When you install the following panels combine the locking of the panels - slats.For a fully monolithic coating the joints between slabs set fill with foam, which cut off the excess after hardening.

In fact - this Penoplex layer assembly process can be considered complete will only solve the problem with the finish.This ceiling may be plastered by applying reinforcement via glass fiber mesh.Another option - oblitsevat its decorative panels or "sew" plasterboard, on which it is already possible to perform any finish.

It would seem - everything is simple and logical.It becomes even it is not clear why such a method available are not widely known?

And, it turns out, the point is that such a ceiling lining Penoplex has no relation to the quality of sound insulation.To understand this, it is worth a closer look at the physics of sound transmission in high-rise building and the properties of the material itself.

Why do still not worth it?

inquisitive landlord should not be limited to the first available recommendations.Much more can be gained from "walk" on the forums of experts in construction matters, and here it is waiting for an unexpected "surprise".Almost all the skilled craftsmen called this method of soundproofing is absolutely ineffective, "carelessly", not only in bringing the desired apartment quiet, but capable of even aggravate the situation.This can be understood on its own, penetrating deeper into the problem.

As the sound propagates in the high-rise buildings

Distribution of noise in high-rise building is in two main ways.

• «Air" air noise transmitted vibrations.This is the normal audible range of the human ear sounds - talk, turn on the TV or audio center, playing musical instruments and the like.The penetration of noise through the ceiling - not as pronounced as the air you need to "shake" massive membrane, whose role in this case is the range, transmitting, in turn, these fluctuations on.

However, a disturbing factor may still be.Often these problems can be solved simply "administrative" methods - you can try with your neighbors in an amicable agreement on the mutual respect for the right of silence mode.Incidentally, in this matter the location of the apartments does not matter - the sound waves propagate in all directions and staying on top may be no less suffer from increased noise downstairs neighbor.

• Impact noise - a sound propagation some other kind.Its source - mechanical - shock or vibration effect on the surface.Fluctuations in this case passed on floors, which are themselves also become a carrier, and the source of the noise, the sound of donating directly to the premises.Moreover, these fluctuations are perfectly transferred from the plate to all adjacent structures, and with the noise of the hardest fighting.

It may be the sound of footsteps or children jumping, falling utensils, work building tools, rearrangement of furniture, folding sofa.By the way, in the same way and subject to low-frequency vibrations of, for example, included a loud home theater subwoofer, unsuccessfully installed the washing machine, etc.

• There are also structural noises that are caused by equipment operating in the building - it may be ventilating or conditioning installations, boilers, piping, etc.Such fluctuations may have and air, and shock (vibration) spreading.

sound transmission in different types of buildings also has its own characteristics.

• Panel reinforced concrete houses, which at one time were built en masse everywhere for a speedy solution to the problem of the housing crisis in the country - the most unsuccessful in respect of sound insulation.

can say that the noise impact on the spread of such a structure freely.The density and massiveness of the walls and ceilings are approximately equal, and the sounds are distributed on all the details, without encountering much resistance without any problems.

• Brick houses (if they really lined entirely of brick, not faced with them) in this respect - the most favorable.Here - a massive thick walls and a relatively thin floor structures.

Impact noise poorly transmitted from lighter to heavier construction, and the walls themselves are well jammed air sound propagation.But "the problem of the upper neighbors" nowhere still persists.

• The houses constructed on such technology is now widely used cast-frame construction, insulation problems are very acute.True, the "shake" a very massive floors - much more difficult, but and vibrations from them light wall partitions are transmitted almost without loss.

Reduced "noise" such apartments - a very complex process that requires a comprehensive approach, and sound just the ceiling surface becomes "like elephant's grain."

Now let's see if able to help in these situations penoplex.

Is penoplex sound-proof material?

First of all it is necessary to make one remark.author of the publication in no way calls into question the highest quality Penoplex as thermal insulation material, which has wide application in construction.The combination of low thermal conductivity, light weight and high mechanical strength allows the use of this material for thermal insulation of foundations and plinths, floors and roof structures, facades and pavements.

Penopleks- excellent material for thermal insulation of foundations!

Even so massive and seemingly invulnerable design as the foundation and the base, require thermal insulation.How to spend insulation foundation Penoplex - in a special publication of our portal.

But how sound-proof material it its developers and not conceived.And if he and inherent in some measure such qualities, then only at a very specific installation method.

Let's deal.

• Will the penoplex protect the premises from the noise of the air?No, it is not much good will.Material although it is porous and light, but it has excellent stiffness and elasticity.Stove extruded polystyrene will likely act as a membrane, which is very easy to "shake up", and it will be an additional "speaker".

Laboratory studies show that the typical structure of the material, conversely, can cause a resonance frequency in the range from about 200 to 500 Hz - and this is just the middle range of the speech!Thus, in this frequency range are not excluded even "insulation failures", ie air noise enhancement seriously enough amount of about 12 - 15 dB.

But what about the data that leads the manufacturer - is that sound proofing (Rw) partitions using Penoplex up to 40 dB?Well, firstly, our issue is not walls and floors - ceiling.Indicator Rw taken into account in the design is simply incorrect - an index of airborne sound insulation, which is used especially for partitions (walls).Secondly, Rw index - very averaged value which takes into account the entire width of the frequency band for the conventional noise housing, i.e. in the range of 100 to 3000 Hz.Third, in a table specifically stated that it is a particular design - two sheets of drywall with a paved between gasket Penoplex.But what is permissible on the walls, it is impossible to implement on the massive ceiling slab.

By the way, experts noted that the increase Penoplex layer thickness is not going to benefit.And if we apply two-layer structure with a rigid "core" and Penoplex on both sides, can generally achieve the effect of reducing the catastrophic insulation - the room turns into a cavity!

To reduce air noise is a combination of the best "weight - sound absorption - the mass."Powerful external barrier (. Item 1) from the noise source is partially reflected sound waves, and "shake" it - quite difficult.Further, the energy oscillation is damped largely lost in the acoustic friable and soft materials (pos. 2), such as foam rubber or special types of mineral wool.And the residual power of these waves is no longer sufficient to transmit vibrations to the second rigid barrier (Pos. 3).Of course not!
