How to properly install a lath under the corrugated board?

In our time, more and more developers and private builders are choosing the corrugated board. This relatively inexpensive roofing material has a long period of operation, reliably protecting the building from the effects of harmful environmental factors. Mount it is not difficult, but you need to follow some rules. In particular, you will need to learn about how to install a lath under the corrugated board.

Its installation must be given special attention. For example, you need to clearly understand the parameters of the roof, because otherwise you will not be able to construct a really qualitative basis. The lining under the corrugated board is often made of wooden beams, the price of which is low. If you do not save on the quality of the material, then such a frame without special problems will be able to withstand the heaviness of the snow cover in winter.

In the construction of industrial or large retail facilities, the metal profile is most often used . This is due to the fact that the roof on such buildings rarely has the right angle of inclination. Because of this in the winter season, it is experiencing huge loads due to accumulated snow, which can only withstand metal. But in everyday life it is much more often necessary to face the fact that the crate under the corrugated board is made of a solid wood, treated with antiseptic composition. Remember that you can only install it after installing a waterproofing layer.

How to install

First, on the extreme rafters, the position of the elements of the crate should be outlined. Carefully measure and inspect all the sites of their future attachment. Everything is superfluous, and if found deep, the ruberoid is laid under them.

Lay the crate necessarily start from the ridge. Note that the step of the flooring under the corrugated board should not be less than 20 cm and more than 40 cm. If the bars are not too long and they have to be spliced, make sure that the joints are on the rafters, and do not hang in the air. In addition, in different rows joints in no case should coincide. At the ends of the roof, you must put the windboards. In height, they should be greater than the height of the rest of the crate, and the required size depends on the thickness of the corrugated board itself.

It itself is attached to the bars with self-tapping screws with zinc coating. It is necessary to use rubber washers as a layer between the screw and the metal. For each "square" lath under the corrugated board requires at least five points of connection. Do not forget to join the sheets of material with rivets.

Use profiled flooring with the expectation that, with its greater thickness, it is capable of withstanding a high load. So, at erection of private houses the material with thickness 0,6-0,7 mm is most often used. If this parameter is less, you will have to mount it on the crate with a smaller step. In this case, the weight will be evenly distributed over it.

For chimneys , ventilation systems, various parapets, you need to make a separate crate. If it is a chimney, then the gap between it and the beam should be at least 15 cm.

So, you learned how to make the lathing under the profiled sheeting!
