Ventilation pipe installation

You want to feel at home comfortably, and to create a comfortable atmosphere, you need to take care of the following: warming, strong walls, reliable roof and high-quality ventilation. If you built a warm house made of natural stone, which will last a century, but did not make ventilation there, it will be very inconvenient to live in it. Absence or inadequacy of ventilation leads to deterioration of the finish, bearing structures and the appearance of diseases in the occupants. In this article we will tell you how to conduct a competent installation of the ventilation pipe in a private house and a city apartment.

Installation of the

ventilation pipe In a private house, the issue of ventilation of residential and technical premises is in the first place. If possible, it should be solved before the onset of cold weather, so that the condensate accumulated over the winter on the walls and windows does not cause damage. To do this, you must select and install the air duct correctly.

Duct selection

First of all, you need to choose the air duct. Depending on the material from which it is made, the performance characteristics change. The most important thing in this business is to correctly calculate the size and choose the type of pipe, and to cope with the installation will not be difficult.

The choice should be made taking into account the provisions of the relevant SNIP, which states that the ventilation pipes must promptly remove the exhaust air from the premises. To make this possible, it is necessary to calculate the length and diameter of the air ducts, starting from the area of ​​the premises, their destination, etc. For example, in the kitchen the air gets dirty faster, therefore, it needs to be taken out faster. But in the hallway or the living room, substitution can be made slower.

Air ducts can be made of bricks, galvanized steel, stainless steel, aluminum or high-strength plastic. Each of the materials has its advantages and disadvantages. However, whatever type you choose, the pipe must be strong, durable, unaffected by atmospheric changes and temperature changes.

If you choose, you can also start from the complexity of installing the duct and the cost of its subsequent maintenance. There are no serious differences in the technology of installing different types of pipes, and the installation is mostly different only in the shape and size of the pipe outlet, which must be done in a wall, ceiling or roofing cake.

Installing ventilation ducts in a private house

Installing ducts on the roof can be done both during the erection of the house and after it has already been commissioned. The method described below is suitable for ventilation in multi-storey and private houses in 2-3 floors. To do this, the ventilation ducts must be made in the bearing walls during their construction. The outlet of the pipe should be located above the ridge beam by 50 cm or more. This will not allow turbulence on the roof surface to disrupt the traction inside. For the ventilation duct to function most effectively, place it in the central part of the house.

The material for the construction of the ventilation shaft was a full-bodied red brick. It has good thermal insulation characteristics, strength and durability. To reduce the likelihood of excessive cooling of the duct in winter, the ventilation pipe laying should be made not less than 2.5 bricks. If the thickness of the machine is small, then, instead of removing the exhaust air from the room, the air duct will begin to draw cold air masses inside.

Helpful hint: To keep the air masses moving unimpeded and flow from room to room, leave a small gap of 2 cm between the floor and the door leaf. Also, special perforations can be made for this purpose. They look pretty aesthetic, and you can choose a lattice or an insert in accordance with the interior design.

If the house is already built, then to build ventilation pipes in it, use polymer or metal products. Installation can be carried out through an opening in the wall or take the pipe straight through the roof. The latter method will take more time and effort, but it will give a better result. Keep in mind that you will have to remove the honor of the roofing cake, and then carefully insulate everything. To reduce the complexity of work, you can use the ready-made passage components made of high-strength plastic. The removal of the pipe through the roof may be necessary for ventilation of the attic space, arrangement of the ventilation system of the sewage system and general ventilation of all residential and technical premises in the house.

Ventilation duct installation:

1. Select the location where the duct will be located. In this case, take into account the requirements of SNiP and the design features of the product.
2. Make the markup by plotting the shape of the pipe section.
3. Cut an opening in the overlap in the layout.
4. A similar hole is made in thermal insulation, waterproofing and other layers of roofing pie. Do not cut everything at once - work with each layer separately, so that everything turned out neatly.
5. Make the layout of the passing node and drill a few holes through which it will be fixed with screws or screws.
6. Place the rubber sealing gasket on the back with a weatherproof sealant.
7. Place the assembly on the gasket and secure it.
8. Insert the pipe into the unit, carefully adjusting its verticality with the help of the building level. Many people prefer to use a rubber cuff instead of a ready-made assembly. It reliably protects the structure against the penetration of moisture and debris, since it is very tight against the pipe.

If you do not want to hole the roof or simply do not need to vent through it, you can put the pipe through the hole in the wall.

How to remove ventilation through the wall:

1. Make a marking on the wall at the outlet of the pipe. The diameter of the hole should be slightly larger than the duct cross-section.
2. Cut out the contours along the intended line, holding the puncher strictly horizontally so that the misalignment does not happen.
3. Knock out the cut out parts of the wall with a hammer or chisel, removing it in parts.
4. Insert the tube into the hole and fill the space between the wall and duct with mounting foam.
5. When the foam dries, remove the excess with a clerical knife.
6. Saddle the outlet pipe from the outside wall with facade plaster, and from the inside - the starting.
7. On both exits of the pipe attach the plastic grilles with self-tapping screws - they will not allow entering into small rodents, insects and debris.
8. If necessary, extend the pipe to the required length, fixing it to the wall using metal clamps.

As you can see, there is nothing difficult in fixing the ventilation pipes, and this work can be handled even without specific equipment and professional skills. But how to be tenants of city apartments in multi-storey houses? There is no way to hole the roof and attach pipes to the facade with your own hands. This we will discuss in the next chapter.

Installing a ventilation duct for the hood in the apartment

In any apartment, the most "needy" for ventilation is the kitchen, as it is where evaporation, smells, and all family members gather. To do this, many people install hoods over the stove. With the choice of extracts, it is not difficult to cope, but what if the ventilation duct is located quite far from the plate? If you do not install the hood above the stove, there will be no use from it. Such situations are quite part, and the pipe for hoods helps to solve the problem.

The ventilation duct in the apartment helps to quickly exhaust the exhaust air to the outside. In the case of an uncomfortable layout in the kitchen, the only sure solution would be to connect the ventilation pipes to the exhaust outlet and the ventilation "window".

Good to know: Specialists do not advise placing the cooker and hood above it in front of the ventilation duct, since a long-length pipe will be required to remove the exhaust air. It's necessary to lay it under the ceiling, which does not look very aesthetic, and the service will be more difficult. Such a pipe will cost more, it will be worse to cope with the task and make more noise. If possible, place the cooker hood directly under the ventilation opening in the wall.

We choose a pipe

Pipes for hoods are plastic and corrugated. We suggest to consider the features of each species in order to choose the best option for your kitchen. So, plastic pipes can be round or with a rectangular cross-section. The first provide the least resistance to air, therefore, they are more efficient than rectangular counterparts. However, rectangular products look more beautiful in the interior, merging with walls and furniture. They can be laid under the ceiling in a corner or on top of a kitchen set.

Advantages of plastic pipes for extraction:

• complete absence of noise during exhaust operation;
• small resistance in round products;
• high aesthetics;
• smooth inner surface is not covered with grease and dirt;
• durability.

In order for the air to flow smoothly through the pipes, it is necessary to know how to connect the ventilation pipes. To do this, together with the air ducts, immediately purchase accessories for fastening and docking.

Corrugated ventilation pipes are cheaper than plastic, and there are a number of natural causes for this. First, corrugation can tear or crack from accidental impact. Secondly, over time, the internal ribbed surface accumulates fat and dirt from cooking. Thirdly, such pipes look not very aesthetically and can shake the integrity of the design. Of course, they can be hidden in a gypsum cardboard box, but this is an additional time and financial cost.

There are corrugated pipes and dignity. The most important of them is the elementary installation. To install such a duct, you only need to attach one outlet to the hood, and the second - to the channel. Fixation is provided by means of metal clamps for ventilation pipes, bolted together.

Helpful hint: Since all hoods have a square outlet, and all corrugated pipes are round, immediately get the appropriate adapter from square to round section. And to ensure the rapid removal of exhaust air, you can buy a pipe with a larger diameter than the outlet hood.

Another nice point of working with corrugation - you can do one piece whole. The pipe is easily stretched, thus sharp bends are not formed, capable seriously to break smoothness of a current of air. Such products are several times less expensive than plastic pipes.

How to hide the pipe from the hood?

Whatever ventilator in the house you have installed, it is desirable that it does not spoil its presence with the interior. Usually in the apartments the ducts from the hoods are laid over the pendant lockers or near the ceiling, but there are more interesting and effective ways to distract them from attention.

If the walls of the kitchen are painted with bright paint, the ventilation pipe can also be made in the appropriate color. In some cases, with its help, you can emphasize the richness of tones, for example, if a bright yellow extract with the same tube is installed in the violet kitchen. For those who prefer a less evocative combination, a paper can be pasted with wallpaper or covered in a plastic box. The latter option is used very often in rooms with suspended ceilings. He weighs a little, so the design can be attached to the ceiling itself.

The ventilation pipe can be turned into an effective element of the interior, covering it with plasterboard. In the sheets, you can insert lights or LED strip, which will give a beautiful additional illumination of the working area.

Installing a ventilation pipe in a private house takes more time and money than working in an apartment, but the very nature of the installation is not too complicated in both cases. With such work, it is possible to cope with any master without outside help.
