Ondulin - sizes, price per sheet and properties

The zealous owner, as you know, not only measures seven times, and cuts off once, but also thinks ten times what to measure. Something like this happens with the choice of roofing material - what is better and what is cheaper, what to do if you choose one or another material, and what is better to refuse?

To find answers to similar questions about the roof of the house is quite simple knowing about the features of modern roofing materials.

Today it’s extremely difficult to surprise someone with an ondulin roof, and it’s almost impossible to so firmly entered this word in the vocabulary of builders and those who are just going to start building houses. But in fact, ondulin, as a roofing material, is not so old, he turned 70 last year, but in Russia, the ondulin craze began a little later in the 90s.

Ondulin - It is one of the types of roofing materials, the basis of which are organic substances. Conditionally, it can be attributed to distant relatives of asbestos-cement corrugated sheets, but this is only conditional, since ondulin has nothing to do with them, except for a corrugated shape.

The main application of this material - the roof, although depending on the desire, sheets of different colors and colors can be successfully used for fences and devices of various partitions, some summer residents use ondulin to arrange beds or decorative garden fencing tracks.

All this became possible due to the fact that, in fact, ondulin is a compressed cardboard impregnated with bitumen and additionally applied with mineral substances. In more detail, the production technology looks like this, pulp in a liquid state is fed to a special molding table, where excess water is removed.

Next, there is the final spin under the press and dyeing. The corrugation is formed on the machine and the guillotine is cut into standard sheet sizes. The next important point is the bitumen bath, where the sheets are completely lowered and impregnated with bitumen, thus, the sheet acquires water-repellent properties.

Further, the application of mineral substances and a drying chamber, where at a temperature of about 250 degrees Celsius, the sheet is sintered and given its final shape. Under natural conditions, the finished sheets of material cool to normal temperature and are packed in transport packaging.

Properties and Sizes

/
Depending on the manufacturer, several types of sizes are available.

The technical and consumer properties of ondulin largely correspond to the main purpose of this roofing material - the temporary roofing device. It is temporary roofs that are the main place of application of ondulin.

Most manufacturers offer a 15 year warranty on the material, while clarifying that this warranty applies only to protect against the penetration of atmospheric precipitation through the material itself, but it can serve for a long time - up to 50 years old.

In addition, it should be said that the ondulin itself is light and easy to install material that does not require special tools and special skills.

Ondulin was very widespread at a time when environmentalists were seriously concerned about the effect of asbestos-cement slate sheets on the human body. Unlike traditional slate, ondulin does not contain carcinogens and is environmentally friendly.

The most popular and frequently encountered size of the sheet standard is European:

  • sheet length over a wave of 2 meters;
  • sheet width - 0.95 meters;
  • thickness - 3 mm;
  • wave height - 3.6 cm;
  • wavelength - 9.5 centimeters;
  • number of waves - 10;
  • sheet weight - 6 kg .;
  • climatic features of use - from -40 to +80 degrees;
  • load per 1 sq. meter - up to 300 kg .;

During production, some deformations may occur, therefore, there are certain tolerances or deviations from the normal size of the ondulin sheet, officially declared by the manufacturers of the material:

  1. Deviations along the sheet length + 10mm / -3 mm.
  2. Deviations in sheet width - + 5 / -5mm.
  3. Permissible deviations in wave height - + 2 / -2 mm.

An important role in calculating the amount of material for the roofing device is played by the exact determination of the so-called useful area of ​​the sheet. This is due to the fact that when laying the material, part of the area of ​​one sheet overlaps with another, both along the wave and from above.

Thus, of the 1.92 square meters of sheet area declared by the manufacturer, a little about 1.6-1.64 square meters will be useful. meter:

  1. Length of sheet 100-150 mm is inlet on the bottom row and overlapping the top next row.
  2. In width the basis of the overlay is 1 wave, that is, approximately 96mm.

Thus, the dimensions of one sheet of ondulin in the calculations are taken - 1850-1900mm * 864mm.

How to calculate the required number of sheets?

Ondulin LeafThe simplest and most effective way to calculate the amount of material is the Ondulineroof calculation program. Simple and fast, just enter the data and the result will not be long in coming.

For those who can not do without a pencil and a calculator, you can simply count the area of ​​individual elements of the roof, leading them to simple geometric shapes - squares, rectangles, to triangles.

Then the whole thing is patience and care. The usable area of ​​1.6 meters is taken as the basis, then the area is divided by the area of ​​one sheet. The result of this operation is the approximate number of sheets of ondulin.

When calculating complex forms of roofs, it is useful to add 5-10% to the resulting result, since it is necessary to carry out the splitting of sheets, overlaps can be more in some places.

Price per sheet

Oddly enough, but it is the price issue that is largely decisive when choosing a material such as ondulin as the roofing material for the roof of the house.

The relative cheapness of the material, its excellent consumer properties and, in addition, the ability to buy in addition to the roofing itself sheets the whole gamut of related materials and roofing elements, largely level the logistics component in price goods.

The base cost that you should be guided when ordering ondulin is to take the price for 1 sheet of standard shale color coating - about 350-370 rubles.

The thing is that the color scheme of ondulin has features in pricing:

  1. The most attractive, and therefore more expensive, is green, followed by red and brown, and finally shale.
  2. About the same price preference are other elements of the roof - endovye, ridge elements.
  3. Often, when selling ondulin, you can pay attention to the marketing move - instead of the price per sheet, for example, shale ondulin at 350 rubles, a price of 200 rubles is proposed, but per square meter, which will be substantially expensive.
  4. In addition to the fact that the price of ondulin per sheet is indicated in the distribution network, quite often a set is offered for purchase “Ondulin + nails for fastening”, in this case it is necessary to more carefully approach the choice of coating and calculate everything benefits.

Average prices for ondulin can be:

  1. Standard shale color - 350-370 rubles per sheet.
  2. Red brown ondulin - 410-4-60 rubles.
  3. The green color of the coating is 420-500 rubles.

Advantages and disadvantages

Ondulin on the roof of the house

Before revealing the advantages and disadvantages of ondulin as a roofing material, it is worth more clearly outline the range of its application - these are temporary roofing. It’s temporary, since 15 years of warranty for coverage is nothing more than a guarantee against leaks itself material, and long enough to find a more durable and reliable coating for building.

The positive qualities of the material, of course, include:

  1. Ecological purity of material, because there is no asbestos in it, which makes ondulin more attractive relative to ordinary slate.
  2. Lightness of material, and, accordingly, savings on the roof structure.
  3. Ease and simplicity of installation.
  4. Relative cheapness material.
  5. Availability of all necessary accessories and additional elements that facilitate the installation of the roof.

But such a long list of positive qualities and advantages of the material is largely offset by the fact that ondulin, due to the presence of natural fibers and bitumen impregnation, Unfortunately, it is a rather combustible material, this minus is largely reduced due to the coating of sheets with special mineral compounds, but this does not solve its main Problems.

Another, however, less dangerous from a consumer point of view problem compared to combustibility is the burnout of the material due to impact on the coating of ultraviolet radiation, this is very noticeable in the first year of operation of the coating, but later, the color change will not be so noticeable.
