What is better to choose ondulin or decking and what is

Nonprofessional masters often find it difficult to choose the right roofing material, because the life of the roof, the comfort and convenience of its use depend on it. The construction market is oversaturated with coatings based on metal, bitumen or impregnated cellulose for every taste and wealth. Sometimes the cost of production helps to decide. But what to do if the materials belong to the same price category? In this article we will figure out what is better ondulin or decking, compare the performance characteristics, advantages and disadvantages of these materials.

Onduin

To understand which material is better suited to overlap the roof, it is necessary to understand what each possible variant is. Ondulin is a modern coating based on cellulose impregnated with polymeric substances and coated with distilled bitumen. It is produced by the eponymous company registered in France and having all the rights to this material. In the process of manufacturing the pulp-polymer mass by the method of forming impart a wavy profile, and then cut into sheets of standard sizes. To give color to a covering, add the painting pigment to it. The leaf of an ondulin has a soft rough surface, and it weighs no more than 6 kg. This roofing material has the following advantages:

1. Длительный срок эксплуатации. Onduin по заверению производителей служит 25-50 лет, что превосходит аналогичный показатель многих других кровельных материалов.
2. Доступная цена. Onduin относится к кровельным материалом эконом-класса, но выглядит не хуже более дорогих аналогов.
3. A light weight. It is one of the lightest roofing materials, and therefore does not require the arrangement of a reinforced solid crate.
4. Механическая прочность. Onduin уверенно справляется со снеговой нагрузкой, даже если слой снега достигает 0,5 м.
5. Низкая теплопроводность. Onduin удерживает тепло, поэтому образуется меньше наледи, сосулек, конденсата, а также снижаются теплопотери через поверхность крыши.
6. Safe for health. Numerous studies have shown that there are no components in ondulin that could harm human health.

Важно! Onduin при повышении температуры становится мягче, пластичнее и теряет механическую прочность, а на холоде он становится хрупким, ломким. Поэтому монтаж, ремонт и обслуживание этого кровельного покрытия следует производить при температуре +5/+15 градусов.

Despite numerous advantages, ondulin can not be called an ideal material for ceiling roofing. Due to its composition and structure, it has the following disadvantages:

• High flammability. Since the main component of ondulin is cellulose, it burns well.
• Lack of resistance to ultraviolet. Under the influence of solar radiation, the ondulin fade with time, and the destruction of the pigment is uneven.
• Subsidence of mud and snow. The rough surface of the ondulin keeps dirt on it and does not allow the snow to slide off the slope, so the roof with such a coating often needs cleaning.

Decking

Profiled sheeting refers to a profiled sheet of thin metal whose corrugated surface has enhanced transverse rigidity. It is made from sheet steel, alloyed with anti-corrosion alloys (zinc, aluminum, molybdenum), and then coated with paint or protective polymers. The weight of 1 square meter of professional flooring is 6-8 kg, depending on the thickness of the material. The professional leaf has high resistance to corrosion, ultraviolet, biological factors of destruction, as well as to mechanical damage. The advantages of this material consider:

1. Long service life. With proper installation and quality service, the professional sheet will last at least 50 years without loss of waterproofing properties.
2. Fire Resistance. The professional sheet does not ignite and does not support burning, therefore it is allowed to be mounted on the roofs of baths and houses equipped with solid-fuel stoves or fireplaces.
3. High carrying capacity. Thanks to the corrugated surface and additional stiffening ribs, sheeting can withstand considerable snow load and even human weight.
4. Smooth surface. The smooth, even surface of the material does not trap dirt and snow, and the ridges directed along the slope effectively transport melted and rainwater into the drain.
5. Длительное сохранение внешнего вида. Decking не выцветает под воздействием ультрафиолетового излечения, не корродирует, поэтому он выглядит аккуратно и красиво в течение всего срок эксплуатации.
6. Affordable price. The professional sheet is cheaper than all metal-based roofing coatings, so it enjoys great popularity.

Обратите внимание! Decking относится к металлическим кровельным покрытиям, а значит, он обладает высоким коэффициентом теплопроводности. Потому если дом оборудуется отапливаемой мансардой, крышу из профлиста обязательно нужно утеплить. Термоизоляция кровельного ската решает проблему перегрева мансардного этажа или чердака в летнее время с большой солнечной активностью.

Also, experienced craftsmen recommend to think in advance about sound insulation, as this material has a high resonating capacity, amplifying the sound of rain, hail and wind. Installation and maintenance of the roofing can be done at any temperature. However, it is necessary to carry out all manipulations with caution so as not to damage the galvanic coating that protects the professional sheet from corrosion.

Factors Affecting Choice

Definitely say which of the two coatings is better is very difficult. Even roofing masters with extensive experience say that in many ways the choice depends on the taste preferences of the customer, because each of the materials has its own advantages and features of installation and operation. Onduin имеют примерно равный срок эксплуатации, стоимость, они оба безопасны для человека, поэтому при выборе пользуются следующими критериями:

• Weight. Ondulin weighs 1.5–2 times less than a professional sheet, so it can be used for houses built on a foundation with a small bearing capacity or with an unreliable roof system.
• Пожароопасность. Если через крышу дома выходят дымоходные трубы твёрдотопливных печей или каминов, лучше использовать профнастил, который является абсолютно негорючим материалом. Onduin можно использовать, если только оборудовать дымоход огнеупорной проходкой и искроулавливателем.
• Шумопоглащение. Onduin обладает высокой шумоподавляющей способностью, поэтому он гасит звуки дождя, града, ветра. Decking, наоборот, усиливает шум, поэтому не стоит использовать этот материал для покрытия мансардных крыш без дополнительной шумоизоляции.
• Удобство монтажа. Onduin гибкий и ластичный, он без труда режется острым ножом, им легко покрывать скаты сложной геометрии с ендовами, «кукушками», слуховыми окнами. Deckingом удобно крыть прямоугольные скаты без усложняющих элементов.
• Skill roofer. Ondulin is easy to cut, easy to fasten on the rafter frame without the use of complex tools, it is suitable for installation by hand. Professional sheet is a more capricious material. Special equipment and some experience in handling the tool are required to work with it.

Note! Profiled sheet without paint or polymer coating is cheaper than ondulin. However, high-quality, durable material with a protective film of pural is even more expensive.
