Decking is a material in the form of cold-formed sheets made of high quality galvanized steel, which has recently enjoyed well-deserved popularity among developers. This article will talk about how do-it-yourself installation of corrugated board on various surfaces and what nuances should be taken into account.
The plasticity of the corrugated board allows you to give this material any shape and size, which allows it to be widely used in such works as cladding ceilings and walls, roofing, as well as the construction of fences and other fences, which is facilitated by a fairly simple installation - the corrugated board has a fairly low weight making it easy to transport and install.
This material has a number of advantages:
- High service life and resistance to corrosion;
- unpretentiousness roofing material and exposure to sunlight.
- High strength of the material with a small sheet thickness;
- Environmental Safety.
Another important quality that corrugated board has is that it can be installed on a variety of structural elements - both on walls and fences, and on the roof.
Regardless of the appearance of the building, it is possible to choose the right type of corrugated board for it, since the market offers a wide range of different colors and profile configurations.
A rather simple installation should also be highlighted - the video of corrugated board clearly shows that the ease of erecting a fence or roof covering deservedly makes it the most popular covering material.
Fixing wall corrugated board
Installation of wall corrugated board includes three varieties: insulation of an existing wall, lining the wall with corrugated board from the outside and from the inside, and using corrugated board as the wall itself.
Consider wall corrugated board - installation of all three options in more detail:
- Warming of the existing wall of the building. Brackets are attached to the bearing wall of the building, after which they are directly mounted - the wall corrugated board is attached to the base using polyamide dish-shaped dowels. To protect the insulation from wind currents, wind-moisture protective films are used.Vertical U-shaped guides are attached to the brackets with rivets, which are necessary for leveling the wall, and a ventilation gap is created between the guides and the film. Further, horizontal U-shaped profiles are also attached to the guides, the step of which should allow the corrugated board to be fastened quite reliably.
For fastening the corrugated board to the wall, self-tapping screws equipped with rubber seals are used. At the same time, corrugated board not only improves the thermal performance of the wall, but also plays the role of a cladding.
As a result, we get a high-quality insulated wall with an attractive appearance.
- Wall corrugated board - installation of internal and external cladding. In this case, corrugated sheets play the role of lining the insulated panel from the inside and outside. First of all, with the help of a roofing material laid in two layers, horizontal waterproofing of the foundation is performed. Then, with the help of anchor universal screws, the lower guide profile is attached to the foundation. Racks are vertically installed and fixed in it, resulting in a frame that includes rack-mounted thermal profiles and panel guides.
Next, the horizontal layers of the vapor barrier film are mounted, which is attached to the inside of the panel using self-tapping screws with countersunk heads.
A heater is placed in the frame made of thermal profiles, which is fixed with jumpers, preventing it from sagging.
The elasticity of the insulation allows you to abandon its additional fastening to the racks.Next, the windproof membrane is fastened to the wall panel from the bottom up in the form of horizontal strips, leaving vertical and horizontal overlaps.
Then, a hat profile is mounted on top of the film, and the film should be pressed against the wall panels, fastening to the racks is carried out using self-tapping screws.
The execution of the direct fastening of the wall corrugated board is carried out in the lower deflection through the wave using self-drilling bolts with a rubber seal.
Fastening of vertical joints is carried out using rivets.
- In the case when there is no need for building insulation, corrugated board can act as a wall that protects the interior from the effects of precipitation and wind currents. This applies to buildings such as sheds, temporary structures and other structures in which the function of the walls is protective and not load-bearing. The installation technology of the corrugated board in this case is quite simple: the corrugated board is fastened to the frame wall crossbars using self-drilling bolts equipped with a sealing gasket. . Just as in the cases described above, the corrugated board is fixed in the lower deflection through the wave; rivets with a step of 300 millimeters are used to fasten the joints of the sheets.
Fastening of corrugated roofing
Before laying the sheets, it is necessary to install the battens under the corrugated board, which is made of wooden bars or steel purlins treated with an antiseptic.
Installation is carried out using sheets with a minimum corrugation height of 50 millimeters.
Roofing corrugated board - do-it-yourself installation includes the following steps:
- Over underlayment film roof waterproofing planks are nailed to the rafters, the thickness of which is from 40 to 50 mm, to which the sheathing boards are nailed.
- Next, steam and waterproofing is performed, which prevents problems such as the occurrence of mold, accumulation of condensate, wetting of the rafters and battens, freezing of the roof, etc. Roofing material, roofing felt or glassine can serve as a material for roofing waterproofing. Waterproofing should be laid on top of the crate, leaving a gap of 4-5 cm between the crate and the film, which ensures ventilation of the space under the roof.
Important: The rules for installing corrugated board prescribe the creation of gaps for ventilation and laying a vapor-permeable waterproofing film. In this case, the film is laid with an overlap of at least 100-150 millimeters, and its sagging between the rafters should be 20 millimeters. The film is joined with an overlap, providing tightness, which is increased by gluing the joints with self-adhesive tape.
- Before you mount the corrugated board on the roof, you should choose the right material. Its length should be no less than the length of the roofing slope, which makes it possible to exclude transverse joints, facilitating the process of manufacturing the roof and increasing its moisture-proof characteristics. In the case when the roofing slope is longer than the sheet of corrugated board, the installation is carried out by stacking sheets horizontally, starting from the bottom row towards the top. You can start laying both from the left and from the lower right corner of the roof. At the joints along the slope of the corrugated sheets, an overlap of at least 200 mm is made, after which the joints are filled with sealant.
- Between the top sheet of the roof and the layer roof insulation a gap should be left, the height of which is 2-4 cm, necessary for air ventilation.
- To fasten the sheets to the crate, self-tapping screws with a diameter of 4.8, 5.5 or 6.3 mm are used, the length of which can be 19-250 mm. Alternatively, hex or flat head screws can be used. A rubber or plastic washer must be placed under the screw head. Self-tapping screws should be selected with such a margin that the length of their threaded cylindrical part is at least 3 mm longer than the length of the package being connected. In practice, 6-8 self-tapping screws per square meter of coverage are usually used.
- Decking should be fastened to roof lathing at the points of contact of the wave, which ensures the absence of a lever between the attachment points and the application of force to the self-tapping screw.
- The fastening of sheets to the lower and upper boards of the crate is carried out in each wave, since this section has the greatest loads from the wind. Fastening to the intermediate boards of the crate can be done through one wave.
Important: fastening of corrugated board in places of longitudinal joints is carried out with a step not exceeding 500 millimeters.
Installation of a fence from a professional flooring
Before erecting a fence from corrugated board, you should mark the territory and install support pillars. The distance between them depends on the length of the sheets of corrugated board and is most often 2.5-3 meters.
When calculating this distance, it is imperative to take into account the clearance to reduce the wind load.
For the manufacture of pillars, various materials are used, such as:
- Supports made of wood;
- Metal supports;
- Reinforced concrete supports;
- Special supports from a profile pipe.
Useful: to protect against atmospheric precipitation, a sheet metal plug is welded to the top of the pole, which also allows you to increase the overall rigidity of the structure.
To install each support, a hole is drilled one meter deep, into which a pole is installed and poured with concrete for the most reliable fixation. Sometimes, in order to facilitate and reduce the cost of installing supports, the pillars are simply driven into the ground.
Next, proceed directly to the installation of the fence:
- Installation of transverse veins (logs, jumpers) is being carried out. For the manufacture of veins, profile pipes are most often used, the size of which is 40x20 mm, and the recommended length is 3 meters. The veins are fixed on the poles using a welding machine. The standard height of the fence is 2 meters, while it is recommended to install jumpers in two rows with the same pitch, which makes it possible to increase the rigidity of the fence. The number of jumpers to be installed is selected depending on the height of the fence being erected: if the height exceeds 2 meters, at least three jumpers should be used.
- After the bearing pillars and cross bars are installed, proceed to the installation of corrugated sheets. For their installation, fastening rivets for metal or self-tapping screws can be used, the color of which matches the color of the corrugated board.
Useful: The advantage of self-tapping screws over rivets is that their use does not require pre-drilling a hole, which makes installation faster and easier.
- Sheets are usually installed with an overlap equal to the length of one wave. To protect against spring meltwater, sheets are usually located at a height of 10-15 cm from ground level.
- Fastening of a professional flooring is carried out through one wave.To fasten one sheet, an average of 12 to 15 self-tapping screws is required - this number allows you to provide the structure with the necessary strength.
That's all I wanted to tell about the installation of corrugated board. You can learn more about the performance of this type of work by watching the video - installation of corrugated board in order to have a visual idea of the various subtleties and nuances of using this material.
