What is better for the roof ondulin or metal - video and
In the process of building their own home, people will definitely encounter difficulties when choosing roofing materials. The fact is, they do not have construction experience, and it seems to them frivolous to focus on advertising or reviews of friends. It is better to make a decision by consulting with a professional master, as well as weighing the advantages and disadvantages of a roof covering. In this article we will figure out which of the two most accessible and popular materials, metal tile or ondulin, is more reliable.
Onduin
Ondulin is a roofing coating based on pressed purified cellulose fibers impregnated with petroleum bitumen and ether resins. This material was invented in France about 70 years ago; in the post-war years, ondulin was used as a means of quick and inexpensive repair of a slate, tiled or metal roof that had become unusable. Currently, there are 2 types of this roof covering:
- Onduin. Он представляет собой листы прямоугольной формы, ширина которых составляет 95 см, а длина 205 см. Высота волны этого материала составляет 36 мм. Визуально он напоминает окрашенный шифер.
- Onduvilla. This is analogous to the classic ondulin, which visually imitates Mediterranean shingles. Onduvilla is a strip of cellulose base, impregnated with bitumen, 40 cm wide and 205 cm long, laid overlap on the slope.
Note! The important valuable quality of this roofing is light weight. A standard size ondulin sheet weighs only 6 kg. Onduvilla is considered a bit harder due to the layering of the piling. The lightness of the material makes it the best solution for the reconstruction of the roof without dismantling the old coating.
Metal tile
Metal roofing is called a roof covering made of galvanized steel by cold pressing. In the production process, the material is given a wavy relief, a protective coating of polymers or paint is applied, and then cut into sheets of standard sizes. This roofing - Finnish technology, which was originally called "Ranilla". Metal tiles are produced in different types, which differ in the shape of the profile, the thickness of the sheet and the composition of the coating. This material has the following specifications:
- The width of the sheet metal is 1.16-1.18 m, this figure depends on the height and shape of the profile.
- The length of the sheet metal is 0.35-8 m, manufacturers have the technical ability to cut the material to an arbitrary size with a step of 35 cm.
- The wave height of the metal tile is 0.22-0.25 cm.
- The step between the crests of the wave is 35-40 cm in accordance with the brand of material.
Important! The quality and durability of metal depends on the composition of the coating. Least of all is unpainted galvanized material, since the galvanic layer of zinc is easily damaged, and corrosion centers are formed. The metal tile varnished or painted is considered more durable material. However, it is better to choose brands with a polymer coating, they are a bit more expensive, but have a higher corrosion resistance.
Mounting technology
Deciding which material is best suited for the construction of the roof, metal or ondulin, pay attention to the complexity of installation of each material. Attraction for the roofing of professional masters increases the cost of the work by 1.5-2 times, so it is important to choose a material that you can use with your own hands.
- Onduin и ондувилла обладают очень легким весом, поэтому с монтажом этих материалов можно справиться в одиночку. Крепежные элементы, необходимые для установки, продаются в комплекте с покрытием, что сокращает расходы. Для настила ондулина организуется обрешетка с шагом 10-15 см, а если уклон крыши меньше 15% — сплошная. Чтобы перекрыть крышу этим материалом, листы укладывают на обрешетку внахлест, а затем фиксируют специальными гвоздями с широкой шляпкой.
- Metal tile считается более капризным в монтаже кровельным покрытием. Так как каждое неосторожное движение может повредить защитный слой, предотвращающий коррозию, поднимать листы и выполнять монтаж лучше вдвоем. Обрешетка требуется решетчатая с шагом 30-50 см. Чтобы зафиксировать листы на основании, нужны специальный кровельные саморезы с резиновой прессшайбой, цена которых составляет 3-5 рублей за штуку. Монтаж выполняется внахлест, края защищаются торцевыми планками, а конек – специальным профилем.
Comparing these two materials, which are approximately in the same price segment, we can say that ondulin is better suited for self-assembly, since it does not require the use of a special tool. If you hire a professional roofer, installing ondulin will cost the customer less by 10-15% than metal tiles. To do metal flooring with your own hands, you will need electric lathes for the metal, a powerful screwdriver, and certain building skills. Poor installation can spoil this type of roofing.
Material comparison
Choosing between metal tiles and Ondulin, one cannot be guided by the cost, since these materials belong to the same price category. Both types of roofing has pros and cons, which are taken into account when making the final decision. Let's compare these materials by the main criteria:
- Strength. According to this criterion, metal tiles are better, since they are made of metal, and ondulin is made of cellulose fibers.
- Срок эксплуатации. Onduin разрабатывался как временное покрытие, поэтому срок службы этого материала составляет 15 лет по гарантии и 30 лет, судя по опыту кровельщиков. Metal tile служит 30-50 лет в соответствии с качеством и ценой материала.
- Огнестойкость. Onduin относится к горючим материалам, а металлочерепица – к огнестойким.
- Sound insulation properties. In this case, ondulin is better than metal tiles, since cellulose fibers effectively dampen the sound of rain, wind, hail, and metal, on the contrary, enhances them.
- Необходимость в снегозадержании. Поверхность ондулина шероховатая, он выдерживает снеговую нагрузку до 950 кг/м2, поэтому установка снегозадержателей не требуется. Metal tile скользкая, поэтому крышу с таким покрытием оборудуют снегобарьерами, предотвращающими стихийных сход снега, хотя оно выдерживает нагрузку до 1200 кг/м2.
- Price. Ondulin cost homeowners a little cheaper, but the life of the metal is 2 times longer.
- Дизайн. Onduin производится всего в 4 цветах, поэтому выглядит однообразно. Цветовая гамма металлочерепицы насчитывает около 100 оттенков, а также покрытие отличается формой волн.
Professional roofing masters recommend using ondulin to overlap structures of a small economic area (gazebos, garages, sheds, sheds). For the roofing of private houses, equipped with heating devices, the roof area of which is more than 30 m2, it is better to use metal roofing.
