Corrugated pipes are quite popular, and the scope of their use is quite wide. Most often they are used to connect hoods to the ventilation system. Positive qualities are due to high-performance characteristics, and the main advantage is the ease of installation. The aluminum foil hose for the hood can be used for arranging chimneys or installing air ducts. This article will tell you about its types, characteristics, installation features.
What is an aluminum foil hose for a hood?
The aluminum foil hose gained its popularity due to its high efficiency as a connector between a ventilation duct and a ventilated device. It is characterized by ease of installation, which can be carried out even by an inexperienced craftsman without special tools. The correct size and shape can be easily created due to the flexible characteristics of the corrugated pipe.
The corrugated pipe for ventilation has a rather simple structure: it consists of metal rings, which are covered with a thin layer of insulating material. Most often, this covering is made of several layers of laminated foil. In most cases, the pipe has a cylindrical shape. There are types of products where the strips of the main material are simply twisted in a spiral. Depending on the type of model, the thickness of the strips can be 100, 120, 150 ml. They are reliably connected to each other by special locking seams, forming an airtight connection.
Due to the compression of the links, the flexible outer layer folds into an “accordion”, and when they are stretched, the pipe can increase several times. The softness of the frame allows not only to stretch the structure but also to bend it at the desired angle. The long pipe can be serpentine, making it suitable for use in the most inaccessible places. An aluminum foil hose is ideal for inconvenient placement of the ventilation system or in a small apartment.
Classification of aluminum foil hose
Corrugated pipes are made from a variety of materials of various lengths, basic shapes, and diameters. Plastic pipes are available in different colors. The price range is also quite wide. These basic differences are at the heart of the aluminum foil hose classification. Product manufacturers offer a variety of models – from colored and thin transparent plastic to special stainless steel culverts. When choosing, it is necessary to be guided not only by external features but also by the production characteristics and purpose of the product.
The scope of application of the corrugated pipe is very wide. Models with a large diameter (over 3.5 m) are laid under highways and under railways, where they function as reinforcing walls on culverts under embankments. Radically opposite thin models are used as insulation or for water drainage. An example would be an air conditioner flute.
Helpful advice! When choosing a aluminum foil hose, you should pay attention not only to its color and harmony with the interior, but also to the corresponding type of pipe, which has a narrow purpose.
According to the external structure, the aluminum foil hose can have the shape of a circle, rectangle, or square. Various materials are used in the production of corrugated pipes. Their list is very wide:
- Cink Steel;
- stainless steel;
- aluminum foil;
- textile fiber;
- polyethylene of varying degrees of pressure;
- polyvinylchloride cloth.
Each of the types deserves special attention since its direct purpose depends on the structure of the material and the dimensions of the pipe. The most popular aluminum foil hose in this list is made of stainless steel or aluminum, which is most often used in the installation of home ventilation. Based on the production methods, corrugated pipes are divided into the following types:
- Wireframe. They are metal frames covered with foil or film. The flexibility of such ducts allows you to restore the original undeformed appearance.
- Spiral-wound. They are in the form of metal tapes with medium flexibility. The product can be stretched twice as much, but after that, it cannot be returned to its original position.
Polyethylene or plastic aluminum foil hose is applicable in the arrangement of plumbing, for example, for supplying water to various types of household appliances. In addition, an aluminum foil hose is widely used in the installation of sewer ducts inside the apartment, in particular under the bathroom or sinks.
Scope of aluminum foil hose: for ventilation, heating, chimney ducts
Different materials from which the product is made, and the size of the aluminum foil hose indicate its wide purpose in various fields. Thin, thin, but long plastic or polymer pipes are used in the installation of various networks. These can be electrical, telephone, television, power, and fiber-optic internet cables. For insulation of electrical wires, an aluminum foil hose with a diameter of 15 to 40 mm is used.
Less flexible corrugated metal is used in heating systems because such pipes are quick and easy to install. A section of the required length can be easily bent in the right place without changing the diameter inside, which makes it possible to create a heating system is difficult and hard-to-reach areas.
Pipes with great flexibility are suitable for ventilation systems. The diameter of the aluminum foil hose for the hood corresponds to dimensions from 10 to 15 cm. Sometimes these indicators reach 20 and even over 30 cm. Such options are rather an exception, although they can be easily found in the trade sphere. The most common material for the aluminum foil hose used in the kitchen ventilation system is aluminum foil. Less commonly, in domestic conditions, plastic or stainless steel pipes are used.
Textile ducts are used to equip communication systems in industrial premises because they do not impede free air circulation. They are widely used in meat processing plants or catering establishments.
Aluminum foil hose: advantages and disadvantages
Aluminum, galvanized aluminum foil hoses, or stainless steel pipes are used for arranging air ducts both in industry and in domestic conditions. This is due to the reliability and strength of the metal.
Helpful advice! Aluminum aluminum foil hose is much cheaper than their counterparts made of galvanized metal or stainless steel, but good-quality pipes have a more presentable appearance.
The most popular of the metals in the list of corrugated pipes are aluminum, which is achieved due to its high resistance to temperature extremes. It can withstand frost of -30 ° C, does not burn or melt even at +250 ° C. This is the main advantage that allows the use of an aluminum foil hose for a gas water heater, but not the only one. Other advantages of the material are given below:
- strength and resistance to chemical attack;
- excellent aerodynamic properties;
- ease of installation achieved due to flexibility and the ability to stretch the pipe to the desired length;
- ease of cut, since the desired length can be cut with ordinary scissors;
- a wide range of diameters of the required model (range is from 100 to 150 mm);
- does not require additional protection from external influences, even on the front side;
- acceptable price.
Among the disadvantages of stainless steel and aluminum air ducts, it should be noted:
- catchy and rude appearance;
- excessive lightness, which leads to the formation of dents during installation;
- the inability to return to its original shape after stretching the pipe, which requires special care;
- difficulty in washing due to multiple folds on the aluminum foil hose;
- the impossibility of dismantling, since the tightness may be compromised.
How to choose an aluminum foil hose for Cooker Hoods?
Choosing the right pipe model requires an individual approach and a thorough study of all the features. In this case, the following basic criteria should be taken into account:
- dimensions of the pipe, in particular, its diameter and length;
- production material at the base of the aluminum foil hose;
- product quality;
In order not to miscalculate with the diameter of the connecting pipe, you must carefully study the instructions that come with the hoods. For added confidence, you can measure the diameter. Failure to comply with the recommendations can have irreversible consequences when even very expensive equipment will not function properly. The standard diameters of pipes installed on hoods are 10, 12, 12.5, and 15 cm. Other sizes are much less common but are still on sale. Most often, hood manufacturers provide parameters corresponding to 100 and 120 mm, and they are indicated in the installation and operation manual of the equipment.
Often, the manufacturer also sells an air duct along with ventilation equipment in a set. This is ideal if the length of the pipe fits the size of the kitchen. Otherwise, you will have to buy a product of the appropriate size. It is advisable to measure the length before purchasing a pipe. For this purpose, a regular tape measure is suitable. Measurements are made from the exhaust pipe to the entrance to the ventilation shaft, observing the strict trajectory of the future pipe run.
Do not forget that the aluminum foil hose is capable of stretching and bending. For some models, this parameter corresponds to 180 °, which allows you to choose the optimal ventilation path. It is also worth considering that the installation of the pipe is already carried out in a stretched form.
Aluminum foil hose: metal or plastic
The material from which the ventilation duct is made is of great importance. In particular, the advantages and disadvantages of metal and plastic products listed above should be considered. In particular, it is necessary to remember the high noise production of plastic products, but it is also necessary to emphasize their high aesthetic characteristics, which allow the installation of a pipe when its masking is difficult.
The most acceptable option is an aluminum foil hose for the hood, which is a multilayer product made of polyester and aluminum interlayers. Steel in the form of a spiral serves as a reinforcement, which sets the required degree of rigidity and the direction of the pipe. Aluminum products inside can be smooth or corrugated. The smooth surface creates an increased level of aerodynamics, which makes it advisable to install them on long tracks with few bends, but such material is less flexible. The corrugated tube is less aerodynamic, but more flexible, which allows it to set the most complex trajectory.
Helpful advice! At the time of purchase, it should be noted that the initial length of the ventilation aluminum foil hose is 60-70 cm, but when stretched it reaches three meters.
When choosing a pipe for extraction, you need to pay attention to the manufacturer and the quality of the material. To this end, it is worth asking about the availability of a quality certificate for products and a warranty period. It is also necessary to visually examine the purchased material, excluding the presence of dents and other visible damage. It is better to refuse to buy a product of a dubious type and look for a more acceptable option.
Installing a pipe for an exhaust: the subtleties of installation, tools, and materials
It is better to purchase all materials together with an aluminum foil hose, which will allow you not to miscalculate in size and quantity. Before going to the store, you should take control measurements. And it is better to select the aluminum foil hose of such a size that you can easily disguise the structure. The most convenient way to place the duct is when it is completely hidden under a false ceiling, panels, or in a closet.
Helpful advice! If the purchased pipe turns out to be shorter than the required length, then it can be increased by connecting it to a section of another pipe. For this, the parts are connected with metal tape. It should be remembered that the fewer connections, the higher the reliability of the design, since each adapter provides additional resistance to flow.
Connecting the corrugated pipe to the hood on one side and to the ventilation duct on the other is a job that even a novice craftsman can do. To organize the process, it is necessary to prepare additional materials and tools in advance. For work you will need:
- corrugated pipe of appropriate diameter and length;
- 2 clamps;
- aluminum tape;
- lattice with a non-return valve;
- silicone-based sealant;
- adapters (if it is necessary to connect a round pipe with a square or rectangular inlet on the hood);
- adapters of a smaller or larger diameter are purchased only in case of emergency when the required size is not found, otherwise, this will reduce the productivity of the hood.
Before starting installation work, it is advisable to clean the ventilation duct and check the draft. This can be done by attaching a piece of paper to the hole. If it is held by gravity, then you can proceed to the installation work. The presence of reverse draft not only reduces the efficiency of the entire ventilation system by several times but can also pose a threat to health.
Installing the aluminum foil hose on the hood: preparation and important details
To ensure reliable and long-term operation of the ventilation system, a number of important points must be taken into account before installation and during installation. If the diameter of the corrugated pipe does not correspond to the outlet at the hood, then it is better to purchase a wider aluminum foil hose by connecting it to the device with a special adapter. This method will have a positive effect, since increasing the diameter will contribute to a decrease in the air flow rate, while reducing the noise in the pipe.
Even before installing the aluminum foil hose, a special interlayer with a grate, a flange, and a return valve is installed in the opening of the ventilation system. This will prevent the pipe from completely blocking the hood. The lattice partition will provide natural ventilation of the room, and the flange will provide forced ventilation. Thus, the kitchen air will be constantly circulated and refreshed regardless of the hood operation. If there is another ventilation hole in the kitchen, you can attach the pipe to one of them tightly, and equip the other with a grate.
The aluminum foil hose is fixed using special fasteners-clamps made of metal or plastic. Do not use glue or sealant to shrink the pipe, as this will make it impossible to further dismantle the pipe for cleaning or replacement.
When installing the structure, you need to make sure that there are a few turns with corners as possible, as this impairs the operation of the system. Each sharp corner reduces the power output by approximately 10%. Therefore, the hood should be located as close to the ventilation opening as possible.
Helpful advice! You should buy an air duct after purchasing the hood. It is this equipment that is the starting point in determining the diameter of the pipe, and the right choice will affect the efficiency and quality of the entire system.
How to install an aluminum foil hose on a hood in the kitchen: stages of work
Installation of aluminum foil hoses involves certain stages and a clear sequence in the work, which includes:
- Drawing up a diagram and creating a drawing with markup. The design is carried out taking into account the placement of kitchen furniture and other additional equipment. The project clearly conveys the entire trajectory of the future duct and allows you to calculate the exact amount of required materials.
- Adjustment of aluminum foil hoses and other elements to the appropriate dimensions specified in the project. If necessary, cut the pipe with scissors or a hacksaw.
- Installation of a reducer of a universal size on the throat of the hood. The device will help to mount a pipe of different diameters. The best option for a kitchen ventilation system is a 120 mm aluminum foil hose.
- The connection of the finned pipe with the exhaust socket. The gearbox is fixed with a sealant, a sleeve is put on it and fastened with a clamp with a special screw.
- Stretching the aluminum foil hose to the desired length and shaping its trajectory.
- Fixing the ventilation duct to the wall. Special brackets with clamps should be installed every meter of pipe length. This step is necessary if the ventilation duct is located at a considerable distance from the hood. This will prevent swaying and excessive vibration of the pipe during the operation of the exhaust system.
- Installing a grill on the ventilation hole. A prerequisite is the presence of a flange and a check valve on it. Fix it with self-tapping screws.
- Corrugated mesh connection. For this, the pipe is inserted into the flange, and the joint is fixed with a clamp.
- Connecting the hood to the network and checking the operation of the ventilation system.
Features of connecting the exhaust pipes to each other
Ideally, the ventilation duct should be located at a distance of up to 2 m from the hood. Otherwise, the efficiency of the exhaust device decreases, which implies the purchase of more powerful and, accordingly, expensive equipment. If a close distance to the well is not possible, then it is recommended to resort to the pipe extension option.
The simplest and at the same time the most reliable way of connecting several pipes to each other is the method using aluminum tape. For this, point joining of the edges of the air ducts and fixing the junction with tape is made. The adhesive tape will ensure a reliable connection of 2 parts of the pipe and protect the channel from depressurization. Finned tubes can also be joined with clamps. To do this, the sealant is preliminarily applied to the edges of both parts, then they are connected and fixed with a screw-on clamp.
In the case of an extended duct, it is especially important to select the hood with the optimum performance. You can check it with a special device (anemometer) by installing it in the base of the pipe. In this case, the pipe and the socket of the hood must match, otherwise, you cannot do without an adapter.
Helpful advice! Although the flute is flexible, it is best to avoid excessive bending, which can negatively affect system performance by increasing the load on the fan. Deteriorate ventilation performance and use of an inappropriate pipe size. It is much more difficult for the hood to push air through the smaller diameter stroke, narrower adapter flange and additional joints.
How to hide aluminum foil hose from a hood in the kitchen: secrets of disguise
Quite often, it is the pipes under the ceiling with a noticeable and peculiar shine that spoil the stylish and harmonious look in a new kitchen, so the final process in installing corrugated pipes is their masking. This process has no functional background but is considered an important condition for the aesthetic design of the kitchen.
Inventive builders and furniture manufacturers (if the set is made to order) can offer several profitable options at once, allowing you to hide unpresentable pipes. The most popular ones are:
- use of a special plastic box;
- construction of a plasterboard structure;
- masking pipes with a suspended or stretch ceiling;
- building hoods and pipes into kitchen cabinets;
- coating pipes with paint or other decorative elements.
A creative solution can be a loft-style kitchen design when the aluminum foil hose is not hidden, but on the contrary, they focus on it. Experienced modern designers will tell you how to correctly beat the shiny corrugated pipe in the interior so that it does not spoil the appearance of the kitchen, but, on the contrary, becomes its decoration and highlight. Fans of classic styles are better off choosing one of the camouflage methods. How to implement each of them, we will consider below.
We mask the aluminum foil hose for extraction into boxes
One of the most popular options for masking the aluminum foil hose is a special plastic box. It is sold in hardware stores. Manufacturers offer a wide range of models, designs, and colors, which allows it to fit into any interior. Sometimes such designs are decorated with original lighting, creating additional comfort. This option is most often used in the case of a close location of the ventilation shaft and in the absence of right angles.
You can hide the air duct under a structure made of plasterboard sheets, which is designed to perform not only a masking but also a decorative function. Placing a curly and original composition under the ceiling will give the interior a special elegance, and the room – additional comfort. At the same time, the drywall box should not stand out particularly in the interior, so as not to create the impression of a cluttered space. Decorating the structure is done using the same materials that are used for the entire kitchen.
Masking with drywall sheets is performed in several stages. First, a crate is created according to the dimensions of the pipe, for this, you can use ordinary metal profiles. Further, the frame is sheathed with plasterboard sheets and fixed on one side to the wall, and on the other to the ceiling. The box can be of various dimensions and looks good as an addition to a suspended ceiling, consisting of several levels, which is also mounted from plasterboard.
Helpful advice! When creating a camouflage structure, you should remember about the malfunctions that may occur during the operation of the air duct. In order to eliminate them, you will have to dismantle the box behind which the pipes are hidden.
How to hide aluminum foil hose under the ceiling
In addition to the plasterboard ceiling structure, you can simply hide the chimney above the suspended ceiling. But in this case, it will descend to a distance equal to the diameter of the aluminum foil hose, which is at least 120 mm, plus the thickness of the material itself and gaps of several millimeters. In the same way, there is a disguise under a stretch ceiling. If in the case of a suspension system, space is stolen, then the glossy surface of the tensioning structure will visually increase it due to its reflective properties.
Thanks to this advantage, the ceiling option is considered the most successful. The main nuance lies in the impossibility of partial dismantling of the ceiling in the event of a breakdown in the system. Then you will need to change the entire structure, and this will entail considerable financial costs. The stretch ceiling will simply have to be reinstalled.
The most economical option for masking the exhaust pipe is considered to be ordinary painting. It is enough to choose a color that is in harmony with the overall interior. It is important to choose shades that are not very bright and catchy, so as not to draw too much attention to the pipe. Another budget option is to glue the pipe with leftover materials from the decor. However, this design will look less aesthetically pleasing.
Aluminum foil hose disguised in a wall cabinet
A modern option for masking air ducts is the use of hinged kitchen cabinets. This is the most acceptable method for concealing built-in hoods. You can lay a pipe in the space between the wall cabinets and the ceiling, decorating the distance with a raised door or a wide strip made of the appropriate material.
However, most often, the hood, along with the pipe, is hidden directly in the headset cabinet. At the same time, there is still enough space in the middle of the hanging furniture for placing kitchen items and dishes. In this case, it would be more appropriate to manufacture custom-made furniture, where the masking of the pipe is provided for by the headset project. The module is designed in such a way that it is possible to trim the side and rear walls to the required dimensions, and the facades of the cabinets will serve as the main masking element. As a result, the headset fits harmoniously into the interior and looks organic. It is quite easy to replace and dismantle pipes in such a structure.
A hanging cabinet located directly above the hob is often used to install (inside) circulation-type hoods. In this case, only the housing of the ventilation equipment will need to be hidden, only the control panel will remain outside. The absence of a pipe means using the space in the cupboard for storing kitchen utensils.
Helpful advice! Under the hood, as a rule, they take a rounded aluminum foil hose. Rectangular air ducts are used in production or warehouses.
Tips for the care of the corrugated pipe for ventilation
Caring for plastic pipes with smooth walls is pretty straightforward. They are easy to disassemble and clean both outside and inside. More complex is the process of cleaning and washing the aluminum foil pipe. The main reason for the difficulties is its embossed surface, which serves as an excellent place for the accumulation of dirt, grease, and carbon deposits. All contamination is very difficult to remove even with the use of special abrasive products. The best option is a banal replacement of the air duct after several years of operation.
Given the low cost of aluminum foil hose, it is considered an affordable and reliable solution to the issue of arranging a ventilation system. If installed correctly, there shouldn’t be any problems at all. It is important to strictly follow the recommendations of the manufacturers and listen to the advice of professionals. Caring for the outer part of the product is quite problematic, so it is better to resort to the camouflage option.
Helpful advice! The service life of the plastic smooth duct is much longer due to its high performance characteristics. At the same time, it costs an order of magnitude more and is not suitable for installation with heating devices.
After 7-10 years, an impressive plaque forms inside the product, which cannot be removed in any way. Therefore, after this service life, the aluminum foil hose simply needs to be replaced. If the pipe path consists of many bends, then the effective service life is approximately halved. Dismantling and installation of a new system is carried out according to the instructions described above.
The correct and deliberate choice of the air duct, as well as its sequential installation in accordance with the instructions, directly affect the quality of the ventilation system and its service life. Careful operation and timely replacement of the pipe are equally important. Even a rather long corrugated aluminum pipe will not spoil the overall appearance of the kitchen if the ventilation system is properly masked. The combination of all these factors guarantees the durability and reliability of the service of such a primitive, at first glance, product as an aluminum foil hose for a hood.
