More from the Middle Ages in the roofs of the roofs use slate. He received his name from the German word "Schiefer", which is translated as a slate. Previously, it consisted only of clay slate, which was mined from rocks. Today, the slate is rarely used, and preference has passed to asbestos-cement material. But call him, as many centuries ago. Also called roofs with other nonasasbestos materials. This kind of roof is perfect for the coating of the pitched roofs.
Species of slate sheets
Wave slate can clearly standardize the format. This was done to simplify the roof layout and the rapid calculations of its required amount. The sheet format must consider the following parameters: size, thickness, weight, length, height, width and wave step. It is worth highlighting the 3 main size of the wave slate:
- The sheet in the 6th waves has the following dimensions: width (175 cm), height (112.5 cm), thickness (6.0-7.5 cm.). The weight of such a sheet is 26 or 35 kg, depending on the thickness. The distance between adjacent waves is 20 cm. This type of sheet is the most durable. Because of this characteristic, it is most often put on the roofs of industrial buildings. The average price varies within 200-240 rubles.
- With 7 waves, it has such a size: width (175 cm), height (98 cm) and thickness (5.8 cm). In this case, its weight is 23.2 kg. Price in the area of \u200b\u200b230-270 rubles. Such type, multi-line, broken and duct roofs are most often lined.
- With the 8 waves comes with a width (175 cm), a height of (113 cm) and a thickness (5.2-5.8 cm). Weight of one such sheet 23 or 26 kg, respectively. The price is within 240-290 rubles. Most often used in coating wide single, four-tight and holm roofs.
Advantages and disadvantages of wave slate
Among different species , For comparison of the advantages and minuses, it is worth highlighting two main. This is a wave, about which is speaking, and flat. Both are very popular and deserve the details of the characteristics. But first, it is necessary to consider the pros and cons of any kind of asbestos-cement slate.
Pluses asbestos cement:
- It is a very durable material. This characteristic is due to tandem asbestos fibers with cement. As a result, the material is obtained, which easily withstands the weight of an adult.
- Asbestos cement has low heat and thermal conductivity, which is a protective factor in hot weather.
- Not amenable to oxidation over time. In this, it wins very much in comparison with the metal roof. The operating time is over 25 years.
- It does not have the properties of electrical out, which serves as protection in the roof of the zipper. At the same time, the current just envelopes the building.
- If one sheet is damaged, there is no need to repair the entire roof.
- It is fire-resistant and does not throw away poisonous substances into the environment during a fire.
- During the shower, the water drops are divided into its surface, and the noise is dissipated and almost silent in the house. What you can not say about the metal roof.
Cons of Asbestoscement:
- It has long been talking about the ability of asbestos to provoke the formation of cancer tumors. In most cases, the bottom cancer is found, the fibroadenoma of the uterus and hemangioma.
- Although it is a sufficiently strong material, it is inherent in the predisposition to splitting during a break, roof or operation.
- Due to the decent weight, it becomes a difficult task to raise the entire batch on the roof.
- During the fire, it is very heated. Having reached the critical temperature marker, he rushes with great strength and releases sparks. These sparks are able to transfer fire to the nearest buildings.
- Badly feels in a rainy area. The moisture is absorbed into it, cement turns and becomes fragile. Also, permanent humidity leads to an ingestion of its moss.
Now consider the advantages of wave asbestos-cement slate
- Having a wavy shape, adjacent elements are connected to each other and are more stable.
- Water flowing through the skate is collected in separate streams, which optimizes this process. At the same time, it is evenly distributed over the drain.
- The structure of the wave leaf allows you to optimally distribute the weight of the person standing on it.
- The wave leaf is perfectly covered with neighboring.
For comparison, the advantages of a flat asbestos-cement slate:
- It has a smaller area, which leads to a decrease in its mass and price.
- It's easier to trim and customize for the required size.
- It can be fixed to the base anywhere having any size.
Counting the required amount of wave slate sheets
In order not to spend extra money, you must follow certain rules when calculating them. In fact, everything is quite simple. We must not forget that the sheets will overlap. It goes on average 30-40 cm. This size must be taken away from the actual one. Next, the entire area of \u200b\u200bthe skates is divided into a useful area of \u200b\u200bone sheet. To this, it is still necessary to add a couple of units in case of their damage.
