In a broad sense, a wind bar is a wooden board or a metal profile of a certain configuration. It is usually installed in order to close the end holes that may remain between the boards of the roof sheathing. If you do not close these holes, then the wind blows in them, which cools the attic space. Such ventilation is very useful for a hayloft, but not very good for a residential building.
There are many options for installing a wind bar, but it is worth considering the three most common. More about them.
Mounting the wind bar: option one
Lathing boards that protrude beyond the plane of the pediment should be sheathed from below with cornice boards. Most often, their thickness is 25-30 millimeters. Previously, the boards of the crate should be sawn off so that they protrude the same distance along the entire length of the eaves. I.ea stretched cord is used from the ridge to the eaves, along which the distance of interest is marked. The excess is then cut off.
Next, the roof is covered with roofing material, and then the wind bar is screwed with self-tapping screws or nailed. Fastening is carried out along a pair of lines: the first runs in the middle of the ends of the boards of the crate, and the second - in the middle of the extreme board of the eaves, which is hemmed. All this is done in order to exclude the possibility of warping of the wind bar from atmospheric influences. This sometimes happens when fasteners are placed in a single line.
The wind bar with its top should be installed as tightly as possible to the roofing material. Quite often, such boards are supplied with carvings to decorate the house. The pattern runs along the bottom of the board.
Installing the wind bar: second option
If we are talking about a roof made of metal, then the wind bar is called end. It is made of a strip of painted iron sheet, which is bent at a right angle. The width of horizontal and vertical shelves can be 100-150 millimeters. Usually the length of the slats is two meters. The surface may have longitudinal ribs, or it may be smooth. For rigidity, the edges of the plank are equipped with small folds along the entire length.
The wind strip for metal tiles should be installed so as to close the sheet of material from above, and its vertical shelf was pressed against the ends of the boards of the crate. Here the requirements are similar: denserpress the end plate against the surfaces adjacent to it. Since the length of the plank is usually 2 meters, and the length of the roof is much longer, first you need to install the lower one, and then the overlying one, so that an overlap of at least 50 millimeters is formed.
The strips are fastened using colored roofing screws, located at a distance of 400-600 millimeters from each other. Side fastening is sometimes done using wood press washers. The main thing in this business is not to miss, that is, to get into a wooden board. If this happens, then you should not remove the self-tapping screw, as a noticeable hole will remain.
Using the tool
When working with a screwdriver, you should not wrap screws at high speeds, it will be more correct to work at the lowest. If necessary, it is better to loosen the torque, otherwise the view from the side of the end plate will not be very attractive, as it will resemble sea waves. The mounting process will inevitably be accompanied by scratches. They are best painted over with spray paint. Otherwise, the metal will begin to corrode the next year. There is only one difficulty - to guess the shade as accurately as possible. Otherwise, the tinted areas will look very strange.
Roof wind bars: third installation option
This method is relevant for any type of roof, if the house is sheathed with siding. In this case, not a wind bar is used, but a finishing strip. Herethere must be a wooden base in the form of sheathing boards that need to be closed, and hemmed boards. Since siding tends to undergo large linear expansions with temperature changes, its fastening is carried out in the strictest accordance with standard installation instructions. In this case, a press washer or a galvanized end nail with a large head is located exactly in the middle of the hole in any of the vinyl elements.
Wind plank, which is sold in addition to siding, can also be used as a window panel. Because of the wide shelves, it is also called "burdock". This shelf is cut with roofing scissors to the full length to the desired size. The cut edge should fit well into the finishing element. And this edge should be visible. That is, it should not be rested against the finishing element, but should have a five-millimeter backlash. In this case, warping will be excluded, and the burdock will be able to move horizontally quite freely.
Subtleties of preparation
First you need to make a template, that is, a sample of the components of the siding. It should be attached to the installation site. If everything came together, then you can make one set, which will be installed in place. If the location is correct, you can continue. Non-professionals often immediately cut the details for the whole house, which is their main mistake. After assembling the first details, they realize that they made a big mistake. This leads to the need to purchase new material, since this one is no longer suitable forapplication. It is better to prepare everything carefully than to do so.
The wind bar is often used in a combined version when it comes to metal roof tiles and wall siding. In this case, the bottom edge of the end strip should fit as tightly as possible to the vinyl siding throughout. Overlap is not allowed here. The sides should look good and there should be no gaps.
These are the most popular options for how a wind bar can be installed. All subtleties and nuances depend on each specific case.
