A good house should be not only warm and strong, but also beautiful. These characteristics of housing largely depend on the external decoration and the correctness of its installation. The most common today are three options for finishing external walls:
- fake diamond;
- vinyl siding;
- metal professional sheet.
In this article, the last type of finish will be considered - sheathing with a professional sheet. If you decide to use this material, you should familiarize yourself with the technology of the work. It is important not only to calculate the amount of material that will be needed for the cladding, but also to determine what additional elements will be needed. These are corner elements, and levels, and much more.
The choice of quality material
The most popular brand of profiled sheet for cladding houses is a material marked C8. You can use it for the construction of light fences. A huge number of coloring options are on sale. Before installing the material, it will be necessary to mount the racks, the distance between which is 60 cm. If you want to cover the walls with a profiled sheet, you should also pay attention to option C10, which has narrow waves. The bearing capacity of this material is higher than that of the previous one. It is popular as a decorative solution. Analogs of this material are designated as T10 or RAN-10. The step between adjacent racks should be a limit of 60 to 80 cm in this case.
Alternative finishes
C18 has a narrow corrugation, which is much larger in height. It is used for wall decoration and as a roofing material. When installing the crate, small stiffeners are needed that will not allow the profiled sheet to make extraneous sounds. If you need a sheet with wide corrugations, characterized by rigidity and strength, you should choose the material C21. It is universal and well suited not only for walls, but also for roofs, as well as for manufacturing canopies, partitions and fences. Two such sheets are joined together with high tightness.
What else do manufacturers offer?
Before plating the walls with a profiled sheet, you should choose the material. This may also be an option labeled C44. It is distinguished by strength and high corrugations. It is used not only for decorating houses, but also for roofing. If you need a material with high strength, you should choose a universal solution - H57. The metal at the base is quite thick and has additional stiffeners. Another example of a universal professional sheet is HC44. Here the number of stiffeners is large, which increases the strength of the material.
Additional elements
For work, you will also need additional elements. This is the outer corner that is needed to update the corresponding areas of the facade. These elements give the cladding a look of completeness and protect the joints from small debris, dust and rain. You will also need an outer as well as an inner corner. These elements can be complex. To work with the joints of the casing, a docking complex strip is useful. It is fixed to the crate until the installation of corrugated board.
Designing, planning and calculating cash
In order to avoid unnecessary waste, you should pre-calculate the amount of material. But first, you must measure the walls and determine their total area. From this value, you need to take the area of the openings, as well as those sections that are not subject to cladding. The area of the pediments should be added to this figure if there will also be a professional sheet on their surface. The resulting value is divided by the area of one sheet.
In the calculations, it is necessary to take into account the useful width of the canvas, since the corrugated board is laid with an overlap. Typically, the length is 2 m, but for different manufacturers this value can vary from 0.5 to 14 m. If you planned to wall the walls with a professional sheet, you should consider an example. According to its conditions, the house has a rectangular shape and the height of the walls is 3 m. The length of the walls is 4 and 6 m. There are four windows on the walls, the dimensions of which are 1.5 x 1.1 m. On one of the walls there is a 2 x doorway 1.4 m. The height must be multiplied by the length and the area of the walls added together. So you know the area of the casing, which in this case is 60 m 2 .
According to the same formula, the area of openings is determined, which will be 9.4 m 2 . From the first value, the second should be taken away, it turns out 50.6 m 2 . The working area of the walls in this case is equal to this value. The area of the gables can be calculated differently, but the feature of this stage will depend on the shape. If the pediment has the shape of a trapezoid, the bases are added up, which will need to be divided by 2, and then multiplied by the height.
If the pediment is an isosceles triangle, half its height should be multiplied by the base. For example, the height of the pediment is 2 m and the base is 4 m. The calculations will look like this: 0.5 x 2 x 4 = 4 m 2 . Since pediment 2, it is necessary to add 8 m 2 to the total area of the skin, resulting in 58, 6 m 2 .
If you purchase a sheet of grade C8, then its standard dimensions will be 2,000 x 1,150 mm, which means that its area is 2.3 m 2 . The skin area must be divided by the sheet area: 58.6: 2.3 = 25.48. The value must be rounded up, 26 sheets are obtained, but the material should be taken with a margin. Now you can calculate the cost of the material. The sheet can be purchased for 515 rubles. For 28 sheets you will pay 14,420 rubles.
Step by step instructions
Sheathing the walls with a profiled sheet provides for the implementation of three stages. At the first, it will be necessary to prepare the surface, the second stage is the installation of the frame, the third is the installation of additional elements and sheets. If the walls are planned to be insulated, then it is necessary to lay the insulation after installing the frame.
The profiled sheet can be mounted horizontally or vertically. This will not affect the protective functions. An air gap should be left between the load-bearing wall and the casing, which will facilitate the escape of fumes. When cladding a wooden facade, the frame is installed from wooden beams, but a metal profile is suitable for concrete and brick walls.
Training
The wall sheathing with a profiled sheet with insulation provides for the preparatory phase. Under the metal sheathing, the defects will not be visible, therefore, now it is not necessary to level the walls strongly, while it is necessary to eliminate through gaps, cracks and fungus, otherwise the destructive effect will continue.
From the facade it is necessary to remove gutters, ebbs, platbands, lighting fixtures and objects that will interfere with the finish. Walls need to be cleaned of dust and dirt, to check their integrity and repair cracks with cement mortar.
Specialist advice
If the masonry is strongly crumbled, it is necessary to knock out the remaining bricks and lay out new ones on a fresh mortar. If the sites were affected by a fungus, they must be cleaned with a scraper and treated with a chlorine product. If we are talking about wooden walls, they are treated with an antiseptic primer, after which the surface is left until it dries.
Frame and casing installation
Having examined the photo of the wall cladding with a professional sheet, you can understand whether this material is suitable for you. The frame for the skin should be even, the guides should be in the same vertical plane. Even small deviations can cause deformation of the skin and reduce the strength of the entire structure. The guides are mounted on brackets, so the system is easier to align vertically.
On the walls, markings are made for adjustable brackets. It is necessary to start work from the corner. The vertical is determined using a level or plumb line. On the marked lines, it is necessary to put dots with chalk in every 50 cm. Further to the side should retreat 40 cm and repeat the action. As soon as you complete the marking, you can drill holes for all fasteners and insert dowels. Insert paronite gaskets between the wall and the bracket.
When covering a brick wall with a profiled sheet, the holes for the dowels should not fall on masonry seams. For drilling in this case, you can not use a hammer if the bearing walls are laid out of hollow bricks. At the next stage, you need to take a guide profile, which is applied to the brackets and baited with screws.
Using the level, you can check the location of profiles for wall sheathing with a profiled sheet. The design of the bracket will allow the alignment of the crate up to 30 mm. All other frame profiles are installed and screwed in alternately. Around the openings, it is necessary to strengthen the jumpers so that the crate becomes solid.
Features of the work
The wall sheathing with a profiled sheet with insulation at the next stage provides for the laying of slab insulation. Most often, mineral wool is used for this, which copes well with the retention of heat, has a vapor transmission capacity and is easy to install. The plates are fixed from the bottom up, the vertical seams in each next row must be shifted. The insulation layer must be continuous, so you need to ensure that there are no gaps between the plates.
To fasten the insulation, plate-shaped dowels should be used. The holes in the wall are drilled through the material. There should be about 5 dowels per slab. Hydro and wind protection are installed on top of the thermal insulation. Cloths of the windproof membrane are fixed perpendicular to the guide. The upper edge of the canvas is fixed with screws to the upper guide. Neighboring canvases should be installed with an overlap of 10 cm. A base tap is screwed on the lower edge of the frame using self-tapping screws.
What else is important to consider?
If the frame is vertical, you need to beat off the horizontal level, otherwise the tide will be uneven. Cladding a brick wall with a profiled sheet without insulation is carried out according to the same principle. Experts recommend starting the installation of the cladding on the back of the house, heading to the front of the facade. With horizontal installation of sheets, the initial line of fastening will be the corner of the building or the doorway.
The protective film must be removed from the material. The first sheet is attached to the crate from the corner and baited with a self-tapping screw at the bottom. It is set in level and held in one position. Self-tapping screws are installed in the deflections of the wave. The distance between the fasteners is 30 cm.
Covering the walls of the facade with a profiled sheet provides for compliance with an overlap of 15 cm. Alignment is carried out on the lower cut. The fasteners should be 50 cm apart from the joint line. When plating, the vertical deviations cannot be more than 6 mm.
Wall Cladding Estimate
The estimate for wall cladding with a profiled sheet can vary in each case. But on average you will have to pay about 100 rubles for the installation of the subsystem. per square meter. The same cost of insulation in one layer of thermal insulation, the thickness of which is 50 mm.
Installation of waterproofing will cost 30 rubles. per square meter, and the installation of window slopes costs 300 rubles. per meter. Having familiarized yourself with the prices in the estimates for wall sheathing with a profiled sheet, you can find out that installing the facing material costs 250 rubles. per square meter. These prices are correct for a volume of work from 100 m 2 .
Conclusion
Before starting work, you should find out what are the norms of consumption of materials for wall sheeting with profiled sheet. This information has been described above. Among other things, you will also need additional elements like a sloping bar. Its number will depend on the number of door and window openings. This product protects against debris and precipitation, is fixed to the crate before installing the casing. The docking strip, for example, performs the same role as the complex docking strip, but is fixed after mounting the casing.
