How to hide and check: tips
Usually, plastic ventilation pipes are not so easy to disguise, so it is recommended to foresee their location in advance when installing wall cabinets. A great option is the hood and pipes built directly into the frame of the kitchen set. Some suspended ceiling installers also offer their services for design and installation of ventilation. Well, in this case, a multi-level ceiling is suitable. If you place the lower level around the entire perimeter, then all communications will be hidden.
To check the performance of the installed pipes, you can use thin paper, even toilet paper will do. To do this, you need to open the window a little and attach a piece of paper to the lingering grate. If the paper takes a vertical position, then we can assume that the ventilation is mounted efficiently. If the sheet does not hold and falls, then the system does not work. You can check the functioning of the technology using a special device - an anemometer. The device shows the speed of air in the mine. Normal air circulation in the kitchen should be 60 m³/h, provided there is an electric stove.
When checking the ventilation in the kitchen and bathroom, you can use the same methods. Normal air circulation in these rooms should be at least 25 m³/h. If the anemometer determines lower values, and the hood is in good condition, then it is recommended to increase the air flow, otherwise mold will form on the walls due to high humidity, and unpleasant odors will begin to spread around the apartment.
The main causes of ventilation failure can be identified as follows:
- errors at the design stage - in this case, you will have to reinstall the hood, taking into account the mandatory requirements for the air exchange system;
- blockage of the ventilation channel - to fix the problem, you can remove and clean the grate yourself or contact a specialist.
In order for the ventilation system to remain in good condition for many years, the following operating conditions must be observed:
- monitor the condition of the filters and change them in time;
- equip the hood at a height of 65 to 70 cm from the hob;
- periodically check the motor for the presence of fat, if necessary, remove it;
- turn on the equipment in advance of cooking;
- remove dirt on the case with a soft sponge with minimal use of household chemicals;
- position the socket to turn it on so that the wire of the device does not overheat during the operation of the stove.
A ventilation system made of plastic pipes is a convenient and affordable option that does not require special care, has been serving well for many years and still has more advantages than disadvantages.
The installation technology will not seem complicated even to a novice master, but it is better to entrust the calculation of the necessary indicators and design to a specialist. Only then will ventilation effectively maintain the microclimate in the room, protect the residents of the apartment from inhaling stale air and related diseases, and protect the coating of walls and ceilings from rapid wear.

How to hide the exhaust pipe in the kitchen?
Not every pipe is able to aesthetically fit into the interior. Therefore, there are several ways to disguise that will help bring the kitchen into a stylish and modern look.
1. Decorative box for exhaust and air duct.
It can come with a kitchen set or it can be made independently from a metal frame and drywall. Further, the box can be decorated as desired, for example, painted.
2. Plastic sheathing. The method seems obvious, especially if the walls and ceiling also have a similar finish.
3. Pipe painting. The option is only possible in the case of plastic.
4. Disguise with furniture. Today, to order, you can make many additional elements in the kitchen set, with which you can disguise pipes.
Often, fictitious cabinets or visors are used for disguise.
5. Complete masking is achieved by laying pipes inside the false ceiling. But this move is not always justified, since you will get access to the pipeline only by dismantling the ceiling structure.
Installation of ventilation pipes on the roof
Installation of the ventilation pipe on the roof is carried out in several stages, regardless of what materials it is made of. A competent designer necessarily lays in the project a node of passage through the roof. The selection of the node of the passage through the roof is carried out depending on the type of roof. The structure is fixed on the glasses with anchor bolts.
For the manufacture of nodes for passage through the roof, black steel is used, up to 2.0 mm thick. It is possible to use thin-sheet stainless steel with a thickness of 0.5 mm. The type of roof and the type of ventilation system determine the configuration and dimensions of the passage through the roof, while in shape they correspond to the main sections of the ventilation system.
These are industrial products of domestic or foreign production.
Regardless of the country of manufacture, it is important to correctly mount it. . Prior to the start of all work, the workplace is cleaned of contamination, the moisture present on the roof is removed.
Prior to the start of all work, the workplace is cleaned of contamination, the moisture present on the roof is removed.
After determining the place of passage of the ventilation pipe through the roof, in accordance with the requirements of SNiP, markings are carried out on the roof. In each layer of the roof (roofing, waterproofing, insulation), a hole is cut out in accordance with the dimensions of the pipe to be installed. Then markings are made for the passage channel and fasteners. With the help of a sealant, a sealing gasket is fixed in this place, a passage unit through the roof is installed on the gasket and fixed with fasteners. Further, a ventilation pipe is passed through this node, fixing it with fasteners.The entire structure must be mounted strictly vertically, the efficiency of the entire ventilation system depends on this.
After completion of the installation work, they check how well the sealing of the duct elements is performed.
To provide a waterproofing function, ventilation passage units through the roof are equipped with a special skirt. When water is released from the air mixture, it is necessary to install a condensate collector, which is attached to the nozzle.
It will be useful to insulate the duct. On sale there are products made with thermal insulation in the kit. Their cost is much higher. But you can insulate the ventilation structure yourself.
The cheapest material for pipe insulation is mineral wool. The disadvantage of its use is the ability to cake over time, which leads to a deterioration in its characteristics.
The most practical to use are shells made of polypropylene. For installation, simply put it on the pipes and fix it in the places of the seams. Some shells are equipped with special locks that ensure tight connections. For additional sealing, you can use a self-adhesive film, applying it in several layers. The insulation must be fastened securely so that weather conditions do not damage the structure.
The node of the passage through the roof of the profiled flooring has its own characteristics and is performed by additional elements. They help to ensure the reliability of sealed pipe outlets. To perform work on the profiled roofing, an apron is installed, it is located around the entire pipe.In places where the apron adjoins the corrugated board, sealing is carried out with roofing sealant. Also, waterproofing is carried out around the pipe. It is convenient to use a piece of roofing membrane for these purposes.
The node of the passage through the roof structure is a metal system that is used in the arrangement of ventilation shafts. If the system has a general purpose, then it is located on reinforced concrete cups, then it is mechanically fastened. The main purpose of such nodes is the transportation of air flows that do not differ in chemical activity. The humidity level of these streams does not exceed 60%.
