The bituminous flexible tile surface is covered with mineral booting sprinkler. Thanks to her, the roof of the house looks very attractive. In addition to the decorative, important feature of the sprinkle - protection of the roof from mechanical damage, random fires and exposure to ultraviolet.
The fact is that unprotected bitumen gradually collapses under direct sunlight and loses waterproofing properties.
Most of the manufacturers of flexible tiles buy a sprinkling of companies specializing in this product. Made it from different materials. All of them have certain advantages and disadvantages. In the cheapest roofing coatings, the protective role performs the slag (rounded grain-colored grains). Basically, a slate, granite or basalt serve as a flexible bituminous roof that is present in the Russian market.

1 Sleeping from slate
Shale granules have high aesthetic indicators and attract customers with a characteristic reflections. True, over time, they can slightly change the flower tonality. And due to the lamellar shape, the granules shale layer less than other racks to temperature drops.2 Running from granite
Granite granulate - durable and hard. It refers to complex minerals processed. The granules obtained by crushing do not have a rounded form and do not provide a dense fit of the protective sprinkle to a bitumen basis, which slightly reduces the service life of the flexible tile.

3 Running from Basalt
Basalt granulate - wearless, durable, durable. He is deservedly recognized as the best, but at the same time the most expensive version of the sprinkle. In the production process, it is burned in special furnaces at high temperatures together with various mineral dyes. The sprinking thus painted in this way does not fade, does not resolve, and provides a wide tile palette.
It is vital that the sprinkle is distributed over the surface of the bitumen evenly, without skips and firmly kept on it. The most efficient protection provides a layer of granules of different fractions. In this case, the empties between large elements occupy small and the layer is obtained as homogeneous as possible, without lumen.

How to check the sprinkle on strength?
To check the ability of the granules to hold on the surface manufacturers subjected to the roofing material of the brush test. Metal brush with load affects a small sample. It is weighed before and after processing and evaluate the loss of sprinkling. According to GOST 32806-2014, the loss of the sprinkle is permissible - 2.5 g. It is obvious than it is less, the longer service life of the flexible tile.

Mute the color of the flexible tile can dust deposited on the roofs of houses in large quantities. But after the rain, the brightness of the shade is usually restored. Most complaints on the fading of roofing coverage are usually associated with staining of the sprinkling. In order to do not be upset with the change in the shade or even the color of the roof when the flexible tile is selected, it is worthwhile to ask the way to paint the sprinkle and the quality of the dye. There is an aerosol treatment option, in which the dye falls not to the entire surface of the granules. Permanent color for the entire service life The manufacturer guarantees only when staining with the subsequent firing in the furnace.
