Comparative characteristics of corrugated board and ondulin

When building a house, many questions arise about choosing in favor of a particular material. When determining the roofing, it is necessary to take into account a number of factors, such as the area of ​​construction, features of the rafter system, loads ... Also, when choosing a material, it is necessary to consider specific cases. And for acquaintance, you can study the comparative characteristics of corrugated board and ondulin, which are most popular among roofing coatings for private construction.

Ondulin

Ondulin is a bitumen sheet, which is made in the form of a wave. You can also come across names such as bitumen slate or euro slate.

The main difference of ondulin is that it is flexible and plastic. This feature helps ease installation in tight spaces. It also eliminates the possibility of cracking when fastened to nails. Positive properties will be noise and heat insulation of ondulin, resistance to corrosion and rust.

Ondulin is divided into two types: it is performed in the form of tiles or slate. This does not affect the quality in any way, only the sizes of the sheets vary. If the roof has a simple shape, then it will be more convenient to use slate ondulin.

So, the advantages of the material:

  • low cost;
  • long service life;
  • light weight;
  • simplicity of installation and cutting;
  • environmental friendliness;
  • plasticity of the material;
  • sound insulation.

Disadvantages:

  • low fire resistance;
  • a small selection of colors;
  • color change under the influence of ultraviolet radiation;
  • the possibility of leakage during the formation of unwanted joints.

The material is not only flammable, but can also melt at the junction of the mines, therefore, protective measures must be taken. It is important to ensure the quality of the purchased material. When buying, we recommend that you request the appropriate certificate from the seller.

Decking

Decking is a steel sheet that is profiled using special equipment. This event allows you to increase the rigidity of the finished product. A special anti-corrosion coating is applied to the material, as well as primed and varnished on the outside and polymer on the inside.

Benefits:

  • length of service life;
  • economical consumption (provided the roof is of a simple form);
  • anticorrosion;
  • light weight;
  • acceptable price;
  • resistance to weathering;
  • the presence of a wide range of colors;
  • variety of forms.

It is also worth noting that when installing corrugated board a minimum number of joints is formed,  avoiding leaks. If the roof has a simple shape, then the material can be ordered along the length of the slope. This will facilitate installation, however, you will need help with lifting and fastening. Another positive factor in the construction of roofing from corrugated board is the use of unedged boards for the battens, installed with a certain step. This will save on materials.

Disadvantages:

  • low soundproofing properties;
  • the possibility of condensation;
  • the difficulty of working in hard to reach places.

Installation of the roof must be carried out carefully. Leaks may form at the attachment points, therefore it is recommended to use elastic bands. You can also hear complaints about the noise produced by the metal in strong winds or rain. This disadvantage can be eliminated if the thickness of the insulation is correctly selected. 

Construction application

All materials have their advantages and disadvantages. Ondulin and corrugated board are no exception.Both of them are widely used in construction work due to the fact that they still have more advantages. The main positive point is that the price really matches the quality. Both materials are strong enough and will last a long time..

When choosing in favor of one of the coatings, it is important to weigh the pros and cons. Ultimately, you must consider the styling characteristics for a particular roof.

Often you can hear that ondulin will come out more economically than corrugated board, but you can not say that this information is correct, because when calculating the cost of the roof it is worth considering the cost of the entire roofing cake.

When working with profiled steel sheets, fewer joints are formed due to the form of release of corrugated board. Its length can reach six meters (some manufacturers may increase this figure). It is important to understand that even small joints of material joints tend to corrode.

Ondulin, when it appeared on the domestic construction market, was not used for residential construction because of some qualities, while abroad it was actively used everywhere.

Ondulin sheets are very light, so it will just lift them to a height, and work can be done alone. They are attached using any screws or ordinary nails (for wooden crates). But to the corrugated board you have to purchase special roofing screws with rubber gaskets that prevent damage to the material during installation. This will maintain operational performance.

Due to the fact that ondulin - the material is quite thin, it can easily be sawed with a hacksaw, which must be lubricated with oil to prevent slipping during cutting. It will also help the tool not get stuck in the material. Ondulin is resistant to acids and bacteria. But the roughness inherent in the material can affect the accumulation of snow on the roof and will interfere with the natural gathering of snow masses. And this, as you know, is a big minus, because it increases the loads that the material is not able to withstand due to its properties. The average lifespan of ondulin is 20 years.

On the Internet, you can easily find detailed instructions for fastening the material, which includes requirements for the fastening step and the size of the overlap, as well as the stages of installation. When carrying out work on your own, it is important to follow all installation requirements. This will first affect the life of the coating.

As for corrugated board, its popularity is currently at its peak. The demand for the material is explained primarily by the possibility of a wide scope. The surface of the corrugated board is hermetic, and the appearance is quite aesthetic. Its lack of heating in hot weather, which, of course, will affect the temperature in the house. In winter, you can observe the formation of freezing snow to the roof. Therefore, it is important during installation to use existing additional elements, such as a wind cornice, corner strips, as well as snow barriers.

When installing a roof made of profiled steel sheets, it is important to take care of the waterproofing device in the form of special films and membranes, which must be laid parallel to the cornice, and glued at the joints with a special tape. To ensure ventilation of the roof, it is also recommended to leave a small gap equal to 4.5 cm. It is arranged between the crate and the waterproofing film. Then it is necessary to fill the rafters with a thickness of 2 cm. Onto the film.
