How to fix a wind bar on corrugated board

If your corrugated roof is to remain stable and long-lasting in the face of strong winds, you must install a wind bar. Popular because of their strength and resilience to weather, corrugated metal roofs can still be damaged by wind if they are not properly secured.

A wind bar, sometimes referred to as a wind brace or wind strip, aids in strengthening the corrugated sheets so that strong winds won’t cause them to lift or bend. It serves as a support to better distribute the force of the wind across the roof, lowering the possibility of damage and extending the life of your roof.

Look for any wind bars or possible weak spots in your corrugated roofing before attempting to fix a wind bar. For optimal support, these are usually positioned horizontally across the roof at different intervals. It’s critical to quickly install new wind bars if your roof is missing any or if the ones that are there are damaged.

To choose the right size for your wind bars, measure the length of your corrugated sheets. Without bending or warping the metal, they should slide snugly between the corrugations’ crests. To make sure your wind bars can resist the elements over time and are durable and rust-resistant, use aluminum or galvanized steel.

Using the proper screws or bolts, secure the wind bars to the corrugated roofing. As you arrange them along the roof’s length, make sure each bar is securely fastened. Steer clear of overtightening, as this may cause the metal to warp or lose some of its structural integrity.

After installation, make sure the wind bars are still firmly in place by doing routine inspections, especially after inclement weather. To preserve the corrugated metal roof’s protective integrity, replace any damaged bars right away. You can extend the life of your roof and make it more resilient to wind damage by correctly installing wind bars.

Tools Needed: Screwdriver, drill, screws suitable for corrugated board
Steps: 1. Position the wind bar over the corrugated board where you want to install it.
2. Mark the positions for screws through the holes in the wind bar.
3. Drill pilot holes at the marked positions.
4. Place the wind bar back in position and screw it into place using the appropriate screws.
5. Ensure the wind bar is securely attached and test for stability.

Wind bar for corrugated board – functions, characteristics, installation

Metalloprofil roofs are a common solution for designs of simple shape or large area. With this simple roofing material, industrial premises, outbuildings, garden, country houses are often blocked. High popularity is explained by a low affordable metal coating and ease of installation. Manufacturers significantly facilitate the task of self -erecting a roof of metal profile, producing ready -made shaped elements. These details of the structure make up no more than 3% of the total area of ​​the slopes, but affect the life of the roof. In this article, we will tell you what a wind bar is for corrugated board, how to choose the necessary sizes of this element, as well as perform fastening.

A shaped diving element, also known as a winding bar, is used to build corrugated board roofs. It’s a corner where one fixed shelf is fixed to the crate and the other shields the overhanging roof from snow, rain, and wind gusts. Premium galvanized steel with a polyester or purl coating makes up the wind bar. Some producers use stone chips to create shaped elements. The following tasks are carried out by this component of the roof pie:

  1. Protection of the pediment and roof overhang from moisture penetration. The outer surface of the roof protects the roofing material, but melt and rain water or snow sometimes penetrates to the rafter frame on the lower side. This situation leads to the wet of the rafters and crate, which is why even a tree treated with an antiseptic deteriorates. The wind bar that does not pass water retains wooden structural elements, prolonging the service life of the roof.
  2. Wind protection. The side gusts of wind in areas with complex climatic conditions often cause a breakdown and deformation of roofing material. Intensive wind load leads to the breakdown of unprotected edges of corrugated board. The fastening of the wind bar prevents the spoilage of the roofing cake and blowing cold air under the crate.
  3. Giving a roof structure a complete and aesthetic type. Glane chosen to match the main color of the roofing material hide the inaccurate edges of the corrugated board from the eyes, and also help perfectly evenly and efficiently perform the overlook of overhangs with sophims or siding.

Be aware that some builders use less expensive bent metal profiles for wind bars. It is available in all major construction stores, but the color scheme and sizes of the premature elements are restricted.

Types and technical characteristics

Construction standards state that wind planes are necessary when building a roof out of tiles or corrugated board. They are put in place all the way around the roofing structure’s perimeter in order to stop wind gusts and random frames from accumulating atmospheric precipitation. Make the following distinctions between these shaped elements:

  • Pediment (end) bar. It is a corner, one of the fasteners of which is straight and the other repeats the wavy relief of the corrugated board. The front -line bar is attached to the overhangs of the roof located from the sideboard of the structure. This element, necessary to protect the rafters from moisture, covers 1-2 waves of corrugated board, and also closes with a completely endo. Some models are supplied with capinos for water drainage.
  • Carnetic bar. The cornice bar is mounted on a crate of the roof along the overhang before the flooring of the roofing material and the installation of the drainage. It is a galvanized steel corner with a polymer coating with straight, even mounting shelves.
  • Skate bar. For waterproofing and protecting the junction between the corrugated board at the site of the sloping connection, the skate bar is used. It is straight, oval, rectangular. Models with a ventilation gap are also produced that improve air circulation in a roof pie.

Selection of preferred style components for corrugated board

The standard length of windshell elements for corrugated board is 200 cm; however, since the strips are installed with a gap of 50-100 mm, their useful length is actually 190-195 cm. Two sizes of models are available from manufacturers: 40×60 mm and 90×150 mm.

Typical dimensions of shaped prefix components

Crucial! Skilled roofing professionals advise installing a 40×60 mm narrow wind bar on flat roofs and in areas with little wind. Any slope of pitched structure can benefit from a wide bar.

A wind bar can be installed on a corrugated board roof by one person using their hands alone, as it doesn’t require specialized tools or special construction experience to be installed. This calls for a screwdriver, sealant, roofing screws with rubber seals at a rate of five to six pieces per bar, and a metal-cutting knife. The installation site determines the sequence in which the elements are mounted:

  • Installation of cornice bar. On the cornice overhangs of the roof of the wind bar is installed to the flooring of the roofing, until the gutters are installed. It is screwed with self-tapping screws with a pitch of 40 cm, starting from the edge, with an overlap of 50-100 mm. On the time of fastening, the waterproofing film, which covers the crate, is raised and laid on top of the bar. High -quality installation implies that the wind cornice element will be pressed against the inner surface of the drainage gutter, preventing all penetration of moisture from the slope into the rafters. Sometimes for this you require strips made by individual sizes.
  • Installation of a pediment bar. The installation of a pediment wind bar is started at the final stage of roofing. After this operation, it remains only to equip the roof tector. The upper fastener shelf of the bar is 135 mm and 145 mm, it is selected depending on the profile and height of the coating waves. The element is attached from above through the roofing material to the crate of the frame and the end board with a step of 30-50 cm. For this, roofing screws with a rubber or polyurethane washer are used. The installation technology of a pedimated wind plank pay attention! For additional insulation of joints between roofing material and wind strips, special seals, silicone sealant or construction tape are used. According to masters, the greatest efficiency is shown by a special seal that repeats the relief of the profile of a profiled sheet, since it has no restrictions on the life of.

    End -line

    When installing a pitched roof coated in corrugated board, a single detail goes by the names frontal, end, and wind. The installation of it happens at the very end of the roofing process. In addition to being a decorative component of the roof, the wind bar for corrugated board serves many other practical purposes.


    1. Atmospheric precipitation enters the subcutaneous space, which leads to the wet of wood and insulation.
    2. Impulses of strong winds that drive under corrugated trash, snow. The lateral wind changes the temperature and humid regime inside the attic.
    3. Penetration under the coverage of birds and small animals. They spoil roofing materials, provoke the occurrence of an unpleasant odor, increase the likelihood of infection with microbes and fungi.
    4. Strong wind can completely tear off the sheets of corrugated board.

    She has several names as a result: the windfire shields from the wind, the front bar highlights appearance, and the end denotes coating edges.

    Constructive features

    Typically, the wind bar and profiled flooring are composed of the same material. Condronage manufacturers provide the option to purchase final details (additional elements) right away when placing an order for materials. They are painted in the same tone as the roofing and have a curved shape. The end bar is composed of stain-resistant galvanized metal. These kinds of coatings are applied as a layer of coloring:

    • Polyester (based on organic polymer substances).
    • Pural (on a polyurethane base with polyamide).
    • Plastisol (PVC and plasticizers).
    • Varnish.
    • PVDF (fluorine -containing polymers).

    Color coatings have protective properties; they make an object more resistant to environmental stresses like UV rays, precipitation in the atmosphere, and hostile wildlife. The front bar is suggested to be 2-3 meters long, 250–312 millimeters wide, and 0.5–0.55 millimeters thick. The part may have a figured or direct shape. The edges of the edges have two hems to provide rigidity. The end bar’s thickness can vary, ranging from 0.4 to 1 mm. However, 0.5 to 0.55 mm is the ideal thickness because the part is fairly robust and can be bent easily if needed.

    Installation rules

    One of the newest additions is the wind bar installation. The skate installation is the only thing left to do after framing the ends. The following steps are taken in order to install the end element:

    1. To the crate, on which the profiled flooring is laid, the end board 80 mm wide is attached, 25 mm thick. The installation of the board is carried out using construction nails with a diameter of at least 4 mm and a length of 100–120 mm.
    2. On top of the end board, the wind bar is installed. The mount is carried out using roofing screws with a diameter of 4.8 mm. The design of screws implies the presence of a sealing washer (rubber laying). Fasteners should be located in steps 200-300 mm. Installation of self -tapping screws is carried out only with the help of a screwdriver.

    1. The installation of the strips is performed from the lower point of the end towards the skate. Details are joined by overlap. The depth of overflow is at least 50 mm. The fastening of corrugated board using construction nails is strictly prohibited, because the shock load violates the integrity of the protective coating. In addition, while clogging the nails, a hole in the profiled sheet is 1-2 mm more than the diameter of the fasteners. Moisture penetrates these cracks and the unprotected middle of the roof sheet is corroded.
    2. The end of the wind bar is bent to direction atmospheric precipitation drainage. But often the installation of the part occurs with the formation of a gap between the bar and the surface of the profiled coating. In this case, it is necessary to provide for the installation of the seal. Fasten the sealant should be on the inside of the additional element.

    To close the gap, one of the following sealing techniques can be applied:

    • universal self -adhesive;
    • Universal self -expanding (psul).

    These materials complement the roof’s design perfectly because of their inherent qualities. They produce a barrier that prevents moisture from penetrating, resist UV ray damage, and adapt well to temperature fluctuations as low as -45 °C. Certain impregnations guard against mold and fungal infections. The aircraft element should close two waves of coating in order to ensure that the joint between the corrugated board and the bar is 100% reliable in terms of leakage. When all of this information is considered, three categories of installation and component types can be identified:

    1. The use of the frontal part with a wide horizontal part, blocking 2 waves of corrugated board. Fix the second wave on the crest with long self -tapping screws.
    2. The front bar is about 125 mm wide, overlaps only one wave, but the use of the seals is necessarily. Installation with short screws on the end board.
    1. It is allowed to install the frontal part with the device of the end bar. However, such a mounting unit does not seem strong and reliable.

    Is it feasible to forgo the roof’s end component entirely? The building guidelines and standards make no explicit mention of this account. Only in the exposed layer is it diminished by two to three times. The following videos are suggested for familiarization:

    Installation of wind (end) bar for profiled sheet

    The roof is considered high -quality only if it has not only an attractive appearance, but also reliably protects the house from precipitation, melt water, winds and other negative weather phenomena. To perform this function effectively, the set of the roofing system includes many additional elements. One of these details is the wind bar. It is used on roofs of metal sheets and is a metal bar installed on important nodes of the roof structure to enhance them. That is, the wind bar is mounted for cornial overhang and ends of the pediments and prevents melt or rain rainfall to the side and lower parts of the ramp, which often happens with windy weather. Also, the product can be called a end or pediment bar. With independent construction of a private house or when installing only a roofing system, you must have an idea of ​​how such a bar is fixed and, what varieties are available on sale.

    The purpose of the wind bar

    The main purpose of the wind bar is to close the holes formed on the ends of the slopes after laying corrugated board. If you skip the stage of installation of this element, then the roof will remain without proper protection from the rain. As a result, moisture will begin to accumulate in the space of the rafter system and in the shortest possible time will disable not only the roof, but also the supporting structure of the structure. That is why the end -line ending bar is considered one of the important elements, the installation of which is mandatory. In this case, you should not only install the bar, but also do it right. Since in other case, with strong gusts of wind, the element will be torn off, and the metal coating can be deformed. We can say that the purpose of the bar is as follows:

    • protect the room from the wind that can penetrate the house and quickly reduce the air temperature in the cold season;
    • prevent the moisture, that is, rain and meltwater in the under -tributary space;
    • protect the edges of corrugated board from deformation with strong wind gusts;
    • give the roof and the entire exterior of the house an aesthetic and complete look;
    • expand the roofing surface;
    • allows you to install sofites for the ventilation system of the attic of the house correctly and reliably.

    The end strips of different configurations can easily handle these crucial tasks. Users should be aware that the windwall may not always come with the finished roofing and that they will need to purchase this component separately. We’ll go into more detail about what to look out for when selecting the right product.

    It’s essential to make sure a wind bar installation on corrugated board is secure and weatherproof. Homeowners can strengthen and shield their roof from wind damage by taking a few simple precautions, like choosing the appropriate materials, measuring precisely, and firmly fastening the bar. This guide provides homeowners with useful advice on how to carry out this task quickly and preserve the integrity of their corrugated board roof."

    Technical characteristics and varieties of wind planes

    The end bar is a metal sheet bent in the form of a corner. When installing a roof from corrugated board and the wind bar can also be made of this material. It is installed on the edge of the slope, that is, on the end, and presses the coating to the crate, tightly closing the joint. For greater reliability, it is recommended to purchase special plugs that tightly close the strips from the sides. Such strips should protect all the ends around the perimeter of the roof. However, the slopes in different places have different forms, and therefore wind planes are also made of various configurations. The following common options can be distinguished:

    • a pediment bar – necessary to protect against precipitation of the lateral part of the slopes;
    • skate – designed for airtight closure of the gap in the upper part of the joint of the slopes;
    • cornice – mounted in front of the drainage system, on the edge of the slope.

    Apart from the intended use, the product’s configuration might vary. Specifically, we are discussing parameters like length and width. The corrugated board windbreak’s standard dimensions are as follows:

    • The length of the product is 2 m, it is important to keep in mind that the useful area will be less than about 5-10 cm, that is, the calculation should be entered from a useful length that is 190-195 cm;
    • The width of the bar is 9×15 cm or 4×6 cm, while a wider product is used for roofing metal or corrugated board with a high wave and with a large angle of tilt of the roof slopes from the profiled sheet. And a narrow option is great for flat roofs, where profiled sheets with a small wave are used.

    The materials used to produce wind strips can vary. Specifically, three primary options are identified.

    1. Aluminum products are the most affordable and inexpensive option. The main drawback of the material is that it is easily bending and deformed with mechanical exposure. In this connection, it is difficult to install, especially inexperienced users.
    2. Steel – outwardly practically not distinguishable from aluminum planks. However, they are deprived of most of their shortcomings. Products are characterized by high strength and reliability, but their price is slightly higher than aluminum analogues.
    3. Copper – are considered the most expensive type of wind planes, but also one of the most attractive. Such products are not afraid of moisture and perfectly confront corrosion for many years. In addition, they are difficult to damage during installation and operation. However, it is important to take into account that the products have a large weight, which is far from suitable for all roofing systems.

    The roofing configuration will determine which option is selected. The installation of the wind bar will not begin until the appropriate product has been selected and the bar has been manufactured in the appropriate quantity.

    Installing a wind bar can stabilize your corrugated roof and stop future damage if you’ve noticed it lifting or making noise during high winds. Look over the roof to see if there are any loose or damaged sections to start. To guarantee that the corrugated sheets are securely fastened to the structure, tighten any loose screws or fasteners.

    The wind bar should then be measured and cut to fit snugly along the length of the roof. To ensure longevity and resistance to rust, opt for stainless steel or galvanized bars. Make sure the bar covers all of the corrugated sheets by placing it over them. Screws or bolts should be used to secure the bar, making sure they go through the sheets and into the roof’s supporting framework.

    Make sure the corrugated sheets are stable and the wind bar is firmly fastened by performing a final inspection after installation. Examine any loose fittings or gaps that might affect the wind bar’s performance. To guarantee that the roof continues to be protected from severe winds and bad weather, it should be inspected and maintained on a regular basis.
