What is corrugated sheeting
The production process of profiled sheets is quite simple. So, the raw material is galvanized sheet in a roll with a thickness of 0.35 to 1.2 mm. Profile forming technology – cold rolling. That is, a roll of steel sheet is untwisted by inserting the end into a rolling mill. The equipment system has rollers of different sizes. They are located sequentially. And the further you go, the larger their diameter.
That is, the sheet is rolled between rollers. Profiles are obtained on it. And in this way rolling continues until the required wave parameters of the corrugated sheet are formed. After which the sheet is cut on a special machine. The maximum sheet length is 13 m, the minimum is 0.5 m. In this case, trimming can be adjusted to any size in increments of 0.5 m.

Today, corrugated sheets are not just galvanized panels, although these are also available for sale. These are sheets painted or treated with polymer compounds with a long service life. Manufacturers are gradually stopping using paint, because the material with a polymer layer has higher performance characteristics. For example, a painted sheet will last no more than 15 years, with a polymer coating - up to 50 years. It should be noted that the finished corrugated sheeting is not painted or polymerized. This ready-made raw material in the form of sheets in rolls leaves the factory in this form. That is, they paint it or apply polymer in a factory using special equipment.
Corrugated sheeting is a certified material, that is, a state standard has been created for it under the number 24045-2010. But it should be noted that not all manufacturers adhere to this document and produce their products according to technical specifications (TU), but this does not contradict current legislation.

So, according to the presented GOST, profiled sheets are divided into three groups:
- wall;
- carrier;
- roofing.
Since the topic of the article is covering a house with corrugated board, we will be mainly interested in the wall option. Although it should be noted that the other two can be used to decorate the walls of houses. They just cost more, so there is no point in resorting to their use.
So, the wall corrugated sheeting is marked with the letter “C” with the addition of digital parameters of the sheet, where the main one is the height of the wave. For a wall one, this size varies from 8 to 44 cm. It is the height of the profile that determines the strength characteristics of the material. The larger it is, the higher the strength.
Most often, the C-8 brand is used to decorate a house with corrugated sheets. Firstly, this is the cheapest option. Secondly, it has excellent strength characteristics. But when choosing a brand, it is necessary to take into account the loads acting on the building. For example, if the wind loads acting on the building are large, then it is better to carry out the cladding with sheets of grade C-15 (20 or 21). They have higher strength and are practically not prone to bending.

And just a few words about the decorative design of profiled sheets. Let's start with the fact that today manufacturers offer almost the entire color palette. But, as experts say, this is already the last century. Because the market sells panels decorated to look like different building materials: wood, brick, stone, sand, etc. At the same time, you can order sheet material with various designs: nature, landscapes, drawings, patterns, etc.
And one moment. Manufacturers today offer corrugated sheets with a double-sided decorated coating. That is, the sheets are decorated on both sides. They are usually used to build fences. For house cladding, it is optimal to use panels with one-sided coating. They are cheaper, and there is no need to use double-sided sheets in this situation.

How to properly sheathe a house with your own hands?
If the product is installed on a wooden surface, it is important to remember that before starting work, the wood must be treated with special solutions to prevent the appearance of bark beetles, mold and fungi on the surface, leading to rotting and decomposition of the wood.
If the rotting process does begin under the sheathing, then damage will occur not only to the wooden structure, but also to the top layer of the corrugated sheet. The inspection is carried out manually, by walking around the house and checking every detail.
If a house made of timber is visited by a bark beetle, its traces can be seen by the rottenness of the surface, and black spots will indicate fungus. The damaged areas are removed and all cracks and gaps are thoroughly plastered.
If the walls have not been damaged, then the owner is lucky, and work can begin on the frame of the structure. The sheathing is performed either vertically or horizontally.
Cross beams are not allowed due to insufficient ventilation penetration into the surface of the house.
The work of installing corrugated sheets on the wall surface can be divided into several stages:
- The surface of the wall is covered with lines arranged vertically. The distance between them should not be more than sixty centimeters.
- Steel brackets are attached to the wall surface for leveling.
- Profiles with a U-shaped structure to the installed
- Heat-insulating materials are installed in the resulting gaps between the profiles.
- After installing the heat-insulating material, you need to attach a vapor barrier film, which will prevent the formation of condensation on the inner surface of the profile sheet and prevent wet drops from hitting the surface of the insulating material.
- After the above steps, you can begin installing the profiled sheet.
- The first sheet is fastened from the bottom of the building. The sheet following the first and subsequent ones are overlapped. This method will ensure reliability and prevent moisture from getting under the skin.
- If we sheathe with imitation, the work will be delayed, and this is explained by the fact that it will be difficult for the craftsman to adjust the material. Therefore, it is recommended to carry out façade cladding from corrugated sheets under a log or wooden surface.
- It is important to monitor the accuracy of the pattern on the surface. It should not have any breaks. This composition is laid across, and not along, the structure, and with obligatory overlap.
- After attaching the profile sheet to the wall, you need to hide the gaps at the joints of the surface using additional materials.
The brackets are mounted on self-tapping screws, ensuring that they are all located on the same line.
In order for the profiles to be installed strictly in a vertical plane, a water level is applied to them.
Mineral wool slabs are most often used. The slabs must fit tightly to the wall surface, so installation can be achieved without additional fasteners.
To do this, you will need self-tapping screws with round washers at the end. It is with their help that the material will be attached to the wall. When turning the screws, you need to leave a gap between the surface of the corrugated sheet and the head so that thermal expansion is compensated.

Technology of house cladding with profiled sheets
Let’s immediately make a reservation that finishing a house with corrugated sheets is the construction of a ventilated facade. That is, a frame made of metal profiles is installed on the outer walls of the building. And then the profiled sheets themselves are mounted on it. Metal profiles for the facade of a house are either special elements or profiles that are used for installing plasterboard sheets.
Let us add that a ventilated facade is an opportunity to insulate the walls of the house from the outside. That is, thermal insulation material is placed between the cladding and the walls of the building. The design is really great. It turns out, as they say, two in one: thermal insulation plus decorative cladding.
Calculation of required material
In order not to increase the budget, it is necessary to accurately calculate the amount of corrugated sheeting required. To do this, the area of window and door openings is subtracted from the total area of the wall, which is the height times the width. Here you can add the area of the gables if they are sheathed with corrugated sheets.

Now you need to find out the usable area of the profiled panels you are purchasing. Please note that each sheet has a total width and a usable width, so to calculate the area, the latter is taken. And now the total sheathed area must be divided by the area of one sheet, we get the number of required panels.
In addition to corrugated sheets, manufacturers today also produce additional elements. There are few of them:
- external corner for decorating the external corner of the house;
- inner corner;
- joining strip , which is used to close the joints formed between two adjacent sheets laid in the same direction;
- end and slope strips ;
- window sill;
- plinth strips.
All additions are selected in size in accordance with the dimensions of the house and its structural elements.

Facing facades with corrugated sheets with simultaneous insulation
The widespread mass insulation of the facades of residential buildings is caused by the tightening of energy saving standards in almost all countries, as well as a significant increase in energy prices over the past 15-20 years.
It is quite difficult to achieve the required energy saving indicators using traditional building materials. To do this, in some regions it is necessary to build buildings with brick walls more than 1 m thick. And this increases the costs of all building structures, starting with the foundations of buildings and structures. Therefore, issues of facade insulation are increasingly being resolved with the help of modern, effective thermal insulation materials.

Heat loss in many residential buildings is reduced using polystyrene foam and polyurethane foam boards. An important advantage of these materials is non-hygroscopicity.
They are attached directly to the wall of the building using anchors and cement-based adhesives. Then their surface is puttied and painted with water-based paints. The technology is very simple and does not require significant costs. But it is quite difficult to call such materials environmentally friendly; at a temperature of about 60°, polystyrene foam begins to decompose. In addition, such insulation is fire hazardous, and their service life is short.
Cladding facades with corrugated sheets has a number of undeniable advantages over the technology described above. Installing a façade from a corrugated sheet to the wall of a building involves attaching a special frame, so a gap can be created between the thermal insulation layer and the corrugated sheeting, which will ensure air circulation between the insulation and the cladding. Such facades made of corrugated sheets are called ventilated.
Facade cladding with corrugated sheets over a layer of insulation
In addition, covering the facade with corrugated sheeting allows the use of thermal insulation materials made of mineral and basalt fibers, which are placed in this very ventilation gap. These materials are more environmentally friendly and absolutely fireproof, and excess moisture is effectively removed from the insulation layer thanks to the ventilation gap.
A ventilated facade can be thought of as a layer cake consisting of a layer of vapor barrier, insulation, a special film called a wind barrier, a metal frame and an outer layer of corrugated board.

The next stage is covering the house with metal profiles. It should be noted right away that corrugated sheeting can be laid on walls horizontally and vertically. Accordingly, the frame elements will be mounted vertically or horizontally. In this case, the cladding, both in the first and second cases, will be a structure with high protective functions. She is not afraid of heavy slanting rain, snow, or strong wind.

Features of the material
Since the corrugated sheet is made of metal, it has all the characteristics of this material
Since the corrugated sheet is made of metal, it has all the characteristics of this material. This is a product made of thin sheet steel. There is no doubt about the strength of the profiled sheet, despite its small thickness, because the surface of the product is profiled. Thanks to the trapezoidal waves on the surface of the sheet, which act as stiffening ribs, the material acquires additional rigidity.
Important: the strength of the corrugated sheet is directly related to the thickness of the steel and the height of the wave. The higher the profile and the thicker the steel sheet, the higher its strength and price.
Since metal is susceptible to corrosion under the influence of negative environmental factors, the product is made of stainless steel. In addition, additional protection is provided by the polymer coating on the front side of the material. In addition to its protective functions, this coating improves the aesthetic qualities of the corrugated sheet, because the polymer layer can have any color.
Among the advantages of corrugated sheeting, it is worth listing the following:
- Galvanized steel sheets with a polymer coating are practically not subject to corrosion. However, for this to be truly the case, during installation it is necessary to pay special attention to the correct processing of the cuts.
- The façade, sheathed with corrugated sheets, is reliably protected from mechanical damage and atmospheric moisture.
- Due to the large area of the product, installation of corrugated sheeting is much faster than covering the facade with siding or brick cladding.
- A large selection of polymer coating colors ensures that you will find a material that matches the color and style of your home.
- Even a wooden house can be covered with corrugated sheets.
- Reasonable price is an additional advantage of using this material.
Among the disadvantages of corrugated sheets is low noise absorption. If you have heard the noise from drops on the eaves during rain, then you can imagine what a rumble will be from the impact of drops on a façade lined with corrugated sheeting.
