Why does the stretch ceiling drop when the cooker hood is switched on??
Why does the stretch ceiling inflate when you turn on the kitchen hood? The fact that the hood in the kitchen is responsible for air circulation in the apartment occurs due to the fact that lowers the density of air in the room, but under the suspended ceiling all tight, and the density remains constant.
One of the causes of inflating and retracting stretch ceilings is the presence of holes and gaps in the rough ceiling. Cracks appear during the shrinkage of the building. With stretch ceilings the same principle applies as in the kitchen hood.
Causes of deformation of the fabric
PVC-film is not a rigid material, so the ceiling can go up and down. Sometimes the effect is very pronounced. The canvas inflates so much that it appears as if water has accumulated inside. Or pressed to the ceiling to the extent that it becomes visible embedding and even the roughness of the plate. As a result, not only does aesthetics suffer: If the film is stretched too tightly, it can tear from contact with sharp corners and noticeable irregularities. Let’s take a closer look at the causes of retraction and inflation.
Gaps in the walls and floors
The first possible cause is a leaky ceiling. It is violated because:
NEFF Ceiling Hoods
- Cracks or holes in the boards;
- poorly sealed joints with the walls;
- Open technological openings (for example, ventilation and electrical ducts, heating pipes).
As a result the air can penetrate into the apartment from the street and vice versa. This occurs due to temperature and pressure differences.
If the wind penetrates from outside, the air is sucked in and the stretch ceiling is inflated. And when the flow from the house moves. the canvas is pulled in and sticks to the surface. The last case on the principle of operation resembles a kitchen hood. In winter the effect is more noticeable with a bigger temperature difference.
The resulting air flow movement is quite strong. If you lift the foil near the chandelier, spotlight or other opening, you can see how it blows from under the stretch ceiling.
Sometimes the film is also deformed when you turn on the hood (even if it is not in the kitchen, and in the room or hallway). It influences the flow in the whole apartment.
Drafts and cold air
In this case, too, the seal is broken, but for another reason. because of ventilation. When the window is opened, cold air enters the room. Warm air rises up and presses on the foil, causing the stretch ceiling to stick to the concrete slab. In winter, during frosty weather, this effect is manifested more strongly.
When the windows are closed, the temperature in the room gradually evens out. Warm air stops pressurizing the ceiling, the film starts to deflate and falls back into place. The next time you ventilate, the situation repeats.
Ceiling sagging. causes and remedies
By analogy with the previous problem, we can assume that the ceiling sagging immediately after installation is the fault of craftsmen and bad installation. In practice, however, it turns out that not always the cause of the defect formed. a low level of qualification of masters. The problem may arise as a result:
Often also ugly and worrying “bubbles” on membrane ceilings are formed due to water getting between the base and the film from the upper floor or roof, tearing of the cloth near the baguette.
Floods caused by neighbors, a leaking roof, or a faulty plumbing system are a challenge for ceilings. Most of even the budget options can cope with the pressure, holding up to a few hundred liters of water inside. You can remove the liquid from the inside without too much trouble yourself or with the help of a master. Usually a small incision is made for this, or water is released through the hole for the lamp.
The Best Way to Remove Scratches from Stainless Steel
A serious tear in the ceiling near the baguette will require, in nine out of ten cases, replacement of the canvas, and in any other place. a cosmetic repair (use patches, capron threads).
Disturbing the appearance of the leaf as a result of decreased temperature in the room is not the worst thing that can happen to this type of construction. It is enough to adjust the temperature regime with further control over it in order for the ceiling to be the same without further intervention.
Note that both sticking and sagging stretch ceilings are problems that can be solved. The main thing. to determine the cause in time and if you can not do it yourself. call a master, who knows exactly what to do and how.
Ways to solve the problem
Sucking or blowing of the stretched cloth is easy to prevent, if the preparatory work is done correctly. But it is also possible to remedy the situation later on.
Sealing the gaps
This should be done even before installing a suspended ceiling. The ceiling is carefully inspected in search of gaps. They are caulked with assembly foam. If the holes are large, you can use other methods. For example, cut pieces of plastic, put on “liquid nails” and coat with sealant.
In addition, carefully inspect the joints of the boards. If the plaster does not hold well, it is better to remove it and re-seal the rustics. It is also necessary to seal the surface around the heating pipes, going into the ceiling. And when outlining during installation of the ceiling, the hole should fit as tightly as possible.
Any hole formed at the junction of the ceiling tiles and walls, ventilation shafts, can cause this phenomenon. Cracks can arise during the shrinkage of the house. To understand why this inflates the stretch ceiling, it is enough to remember the principle by which extractors work in kitchens. Traction provokes the difference in temperature and air pressure in the room and outside. In the case of a blown ceiling, the opposite effect works: the air is not only drawn out, but also blows out of the hole.
There are two solutions to this problem. You can remove the cloth, fix all the problems and install it back. But this approach requires certain costs, not to mention the hassle of the process itself. As a rule, experts recommend a more effective method. installation of ventilation grilles. The stretch ceiling lets the air flow out freely.
The common saying that prevention is better than the search for a solution is perfectly appropriate in this case. By ordering the installation of the canvas with us, you prevent many problems that often arise during the installation of staple technology (wedge). Professional work will ensure that the coating will last a long time and look great. If you want to get a high quality installation, then contact our experts!

Why does the hood inflate the stretch ceiling when you turn it on??
Why a suspended ceiling blows up when you turn on the hood in the kitchen? The problem is that the kitchen hood is responsible for the air circulation in the apartment. T It’s because the density of the air in the room is dropping, but under the suspended ceiling everything is sealed and the density remains constant.
We advise against installing stretch ceilings in situations where the indoor temperature can drop below 5 degrees Celsius.5 degrees. This applies to country houses without central heating connection, as well as similar buildings “dacha” type.
Why is the stretch ceiling inflated when you turn on the hood?
Why the stretch ceiling blows up when you turn on the kitchen hood? The fact that the hood in the kitchen is responsible for air circulation throughout the apartment. It happens because the density of air in the room decreases, but under the suspended ceiling all tight, and the density remains constant.
We believe that you should not install stretch ceilings in situations where the temperature in the room can drop below.5 degrees. This applies to country houses without central heating, as well as similar buildings “dacha” type.
A huge advantage of stretch ceilings is that they allow you to get a perfectly smooth surface. Even a little sag in this situation negatively affects the appearance of the surface. It should be considered for what reasons the ceiling can sag, because there can be many.
- Natural. In this case, the norm mentioned earlier is implied. Sagging in 1% can be provoked by the difference in the room temperature with that concentrated in the inter-ceiling space. If the ceiling covering is provided with ventilation grilles, sagging for this reason will not occur, because the temperature will equalize.
- The second reason for the normal sag is its own weight of the leaf. As noted earlier, this problem is most often encountered in rooms with large areas. This is the reason why in large rooms the canvas is made of several parts.
- Flooding from above. If the height of the sag is considerable, it is probably caused by flooding from the neighbors. In this situation, sagging is not a disadvantage, but becomes an advantage, because the canvas did not allow water to get into the room, damage furniture and flooring. If light-transmitting ceilings of the film type have been used, then after draining the water, they will very quickly return to their original form.
In such a situation the level of deflection can be different. In some cases, the ceiling sags practically to the floor, but the cloth does not tear and can withstand the load. The level depends on the amount of water that got into the space between the ceiling surface and the canvas.
Acting on your own, you can not only damage the canvas, but also flood your apartment.
To solve this problem requires special equipment, with which you can quickly drain the water from the ceiling, without damaging the fabric. Often the amount of water that is concentrated in the ceiling is very large and therefore it is not possible to fit it into a bucket or basin. In addition, the ceiling must be properly dried. If you do not, it will leave stains and streaks on its surface.
- Poor quality material. Often the situation when the ceiling sinks, and it is caused by the use of low-quality materials. This is typical of Chinese products, which are characterized by their low cost. If it comes to stretch ceilings, then in this matter it is best not to save money and opt for reputable manufacturers who have already proven themselves on the best side. It should be noted that often the price difference between high-quality and low-quality stretch ceilings is insignificant, while you will know for sure that the ceiling will be able to withstand different loads and will be completely safe for your health.
- The profile has come away from the wall. There are situations when, for whatever reason, the fasteners in which the stretched fabric is tucked in, comes away from the wall. There is a free flow of air. If you are faced with such a situation, you should definitely contact the company that installed your ceiling, because the cause of this problem is probably due to poor quality fixing the profile to the wall itself. To correct this error will need to dismantle the sagging part, re-enforce the profile and re-tension the coating.
- The presence of defects in the ceiling. There are situations when during the preparation of the base ceiling was not removed all the whitewash, which over time will certainly begin to crumble. This is what triggers further sagging of the ceiling. Sometimes it happens because of the installers’ mistake, who did not pay proper attention to the preparation of the ceiling surface. To correct this defect can only be a professional craftsman, as independently cope with the problem will not work. To do this, lift and clean the stretch ceiling, remove the remains of whitewash and plaster from the main ceiling, and then again stretched the canvas.
What to do if the ceiling is inflated?
Before installing stretch ceilings there is one basic rule that will save you from further problems in operation. It is imperative that the stretch ceiling must be protected against the penetration of wind through the cracks in the main ceiling. If this is not done, the wind flows through the gaps between the floors or in the attic ceiling when a window or door is opened and the ceiling blows up.
And these air currents as if blown by air on the ceiling or pull it in, depending on which side the wind blows. During retraction, the canvas encircles everything on the ceiling. wiring, fixtures, chandelier. Visually, it looks like a bubble was inflated inside the ceiling or vice versa, made a dent, wrinkles and waves may appear on the canvas. Also having this problem, homeowners complain about an unpleasant crackling noise from the ceiling. Agree, it is a little creepy to wake up at night to an incomprehensible creaking noise overhead.
The first reason for the inflation and retraction of the ceiling are holes in the raw ceiling. During the shrinkage of the building, cracks appear. With stretch ceilings works the same principle as in the kitchen hood. The difference in temperature and pressure in the room above and below the ceiling creates a draft of air. And with a stretch ceiling there is also the effect of a reverse loop. the air currents are not only pulled out of the gap, but also blow from it.
This problem can be solved in two ways. For example, you can remove the suspended ceiling, repair all the defects in the concrete ceiling and re-install it. This method is not very convenient, because you have to spend time and money for disassembly and reinstallation. In addition, the very process of finding a vent is not too easy. Masters advise another, more effective method. install ventilation grilles in the suspended ceiling. This allows the air to flow freely out of the ceiling. Representatives of some amateur and inexperienced companies to install stretch ceilings may argue that this is impossible because of the peculiarities of the ceiling materials.
