Stretch cloths are a popular type of arrangement of suspended ceiling coatings. They are widely used in public institutions, public institutions, residential buildings and apartments, in those areas in which fire safety standards allow. As with any suspended structure, ventilation in a suspended ceiling is one of the most important engineering structures.
Unfortunately, there are many companies that can beautifully mount a spectacular cover, but only after many installers do the problems with the indoor climate begin, due to the illiteracy of the installation of the ventilation system
How to check the creation of the correct air exchange, what calculations should be made, which scheme to choose and what norms exist in apartments, where it is impossible to equip new channels in the supporting structures? So many questions, but we have all the answers ready. We will talk about the design options and design features of the ventilation system of suspended ceilings.
Varieties of ventilation with suspended ceilings
As well as for any other design, there are 2 main types of air exchange for stretch ceilings.
It:
- Natural - involves the installation of simple elements for ventilation (air ducts and ventilation shafts) or their absence in order to create a natural movement of the air flow.
- Forced- when the design provides for a fan to create a forced draft
In general, in the arrangement of ventilation in rooms with such a ceiling covering, there should not be a question about how to provide ventilation of a stretch ceiling.
Rather, it is relevant how to integrate a ventilation system into the suspended ceiling so that the canvas does not interfere with air exchange and releases pressure between the ceiling space and the room.
The choice of the air duct system is determined based on the individual characteristics of the room, its humidity level, temperature conditions and the purpose of the room with a stretch ceiling
That is, initially it is necessary to equip a high-quality system, which should be in every house, and only then adjust your suspended structure for it, and not vice versa. You create a microclimate not for the ceiling, but for your health, because the paintings themselves do not need much fresh air.
Natural air exchange and ventilation grilles
As you know, there are different types of ceiling paintings and one of them is perforated. This is a special type of release of the material itself. PVC, fabric - not important. The bottom line is that there are holes on the canvas. They can be randomly arranged or form a single pattern.
Their purpose is initially design. However, in most cases, they also do not interfere with healthy air circulation. Of course, not in all forms, it depends on the location and size of the perforation, but very often thanks to it, the arrangement of additional air exchange devices under the canvas is not required.
But such a canvas is expensive and it is very difficult to masterfully beat in the design sense. Most often you have to think over a system for ordinary paintings.
If the room already has working ventilation, there will be no problems with ensuring air circulation in the ceiling space. Simply install the ventilation grilles or diffusers in the tension web.
There is nothing complicated. And the process itself will not take much time.
1. Installing the protect ring. 2,3,4,5.Cut a hole in the thermal ring for installing a diffuser or ventilation grill. 6. Install the device itself
It is enough to put special tread rings on the glue, cut holes for the devices and install them.
Ventilation grilles or diffusers are installed diagonally in the corners of the ceiling as opposed to each other. By this principle, any air duct system in the room is equipped
It should be noted right away that they do not spoil the appearance of the ceiling, since they are quite compact, and in addition, they look quite decent in appearance, reminiscent of ordinary ceiling lights. In addition, you can choose almost any color that is most suitable for the shade of the canvas.
Arrangement of artificial ventilation
If the ventilation hood or shaft is located in the ceiling space of the bathroom, toilet or kitchen and the suspended structure naturally closes them, it is necessary to install the hood through the canvas of the stretch ceiling using special designs that imply the use of a forced ventilation method.
Through the existing ventilation shafts, it is also possible to arrange air exchange in rooms that are not equipped with a circulation system, but need it.
For the installation of an air duct system, it is best to purchase a ready-made modular design. It is inexpensive and at the same time has all the necessary qualities - compactness, prefabricated elements, tightness
Experts say that in rooms with low ceilings - less than 2.65 m high, it is not practical to install ceiling fans. If we are talking about a bathroom with such a height, it is best to think about installing a hood.
Initially, it is necessary to carry out all the calculations and consider the coherence of creating forced air exchange. And then pick up the material from which the structure will be made.
Air duct can be made of:
- drywall;
- corrugated pipe;
- plastic items.
The latter option is the most convenient and fastest. Consider the usual forced air exchange with the installation of the fan in stages.
Stage number 1 - fixing ducts
The duct is carefully fixed directly to the ceiling surface or to pre-installed suspensions. It is very important that the design is absolutely airtight, otherwise an area of negative pressure will appear and the canvas will “suck” to the base.
A drywall box can become an air duct. Designers often use such a frame as a maxi-decorative design for ventilation. But basically it's better to use plastic
After the ducts are fixed, you need to output all the necessary electrical wires.
Stage number 2 - equip a place for a fan
After installing the air duct, it is necessary to provide a mortgage for the fan. Usually it is made of plywood. The mortgage is attached to the base ceiling with suspensions.
The design of your ceiling system using forced ventilation will look something like this. As you can see, the platform is fixed directly to the head of the ventilation pipe
Stage number 3 - installation of the tension web
Next, the tension web itself is installed, but very carefully so as not to damage the surface. When the stretch ceiling is installed, we need to install the tread ring in the place of attachment of the mortgage.
The width of the tread walls is selected according to the diameter of the pipe, the larger it is, the thicker the walls of the thermal ring. Please note that these devices can be either color or transparent.
Stage number 4 - make holes for the duct
After the ring is firmly fixed, you need to carefully cut the hole for the duct.
This is done using an ordinary clerical knife.
Stage number 5 - connect the fan
Then you can connect the fan.To do this, it must be firmly inserted into the ventilation duct and fixed. Wires are routed through openings in the enclosure and connected via terminals.
Stage 6 - installation of the ventilation grill
We install a ventilation grill on top of our design.
Before installing the system and connecting the fan to the duct in a stretch ceiling, be sure to check the performance of the device, even if the seller tested it before buying
From the opposite corner of the room, you need to install a diffuser or ventilation grid.

Stretch ceiling hood
In kitchens, a hood is usually present. And from this device, engineering structures are drawn that often annoy the owners with their unaesthetic. However, the pipe from the hood can also be hidden in a stretch ceiling and we will now tell you how.
Instead of corrugated pipes, which are usually equipped with ventilation systems, it is best to use special plastic ducts of not round, but rectangular cross-section 55 × 110 mm. They are able to fit as close as possible to the base, which will provide the possibility of minimal lowering of the frame level for a stretch ceiling.
For convenience, if major cosmetic repairs are planned, you can pre-draw the location of the hood so that it exactly matches the installed duct
Be careful, again, all joints must be carefully sealed, and wiring laid in advance, even before mounting the canvas itself.
Another important detail - if the pipeline from the hood passes through other rooms and you want to combine the ventilation system of these rooms through it, be sure to install diffusers with non-return valves so that exhaust air from the kitchen is not drawn into all rooms.
So, you installed the ducts from the ventilation shafts. Now you need to equip the pipe from the hood in the surface of the stretch ceiling. To combine the duct you mounted with the hood, you should use a rectangular adapter on a round corrugation from the device itself.
The finished design will look something like this after all the connections to the ventilation system. As you can see - the pipe sticks out minimally and is practically not visible
A hole is made in the canvas of a suitable diameter for its connection, communications are connected. Well, at the last stage, the operation of the exhaust equipment is checked.
Nuances of arranging the ventilation of a stretch ceiling
Before installing all systems, it is necessary to prepare the surface. In general, in technology, they are mandatory during the finishing work of this type of technology. However, they are most often ignored, believing that the suspension structure is designed to hide all the flaws.
So, first of all, you need to take care of sealing any cracks and joints. Naturally, these are cold bridges that provoke condensation. For this, it is also recommended to carry out thermal insulation. This is true for residents of private houses and the upper floors of the MKD with an uninsulated attic space.
In general, the ceiling should be insulated from the attic space. This arrangement may cause moisture to build up between the ceiling and the insulation.
Next, it is worth taking care of strengthening the structure. With a mechanical ventilation system, a solid base for wiring is very important.
And finally, the last - rodents like to run around the stretch ceiling. They can easily bite the electrical wiring of forced ventilation or get into the air ducts and die there, creating a stench instead of fresh air for the owners. Therefore, it is important to exclude all variants of rodents getting into the ceiling space.
Cons of the ventilation system of suspended ceilings
Manufacturers of stretch linens are very fond of boasting about the degree of stretching of their linens in case of flooding by neighbors from above or leaking roof. Of course, for the paintings themselves, this situation will be stalemate, but at least you will save repairs and furniture if the water does not pour down and is delayed by a stretch ceiling.
So, the installation of additional ventilation holes reduces the tightness of the structure and, accordingly, increases the risk of leakage in these places.
Of course, on the one hand, the ventilation grilles reduce the hydroprotective properties of stretch linens, but on the other, it is easier to drain the accumulated liquid through their openings
When arranging ventilation, accurate individual calculations are nevertheless necessary, which are carried out directly at the facility. Therefore, any instructions can be considered only conditional guidance.
Another important point is the problem of servicing the duct. If there is any problem with the system, you have to remove the entire canvas to fix the breakdown.
Installation of ventilation grilles in the suspended ceiling:
We talked about installing ventilation in a suspended ceiling with our own hands, as you see, there is practically nothing complicated about it. However, one should take into account the fact that, for example, forced ventilation should be made at the first stage of installation of the tension web. And even the usual insert of ventilation grilles, although it seems simple, can lead to damage to the decorative ceiling. Therefore, you should still entrust this to professionals.
