When reconstructing an old building, a serious issue is the choice of roofing material, the use of which would help preserve the original appearance of the structure. One of the few materials of this series is the Granite Cloudy metal tile.
Moreover, today the metal tile of this type is almost the only roofing that mimics ceramics. Moreover, the imitation is not only in profile and shape, but also in the heterogeneity of staining, which is typical for products from baked clay.
Material benefits
An inexperienced consumer wonders if it would not be easier to use natural tiles. Yes, it’s easier, but not always this step is justified - when comparing Claudi metal tiles with natural ceramic material, the first one has a lot of advantages:
- Durability. After several years of operation, the surface of the ceramic plates becomes stained and begins to collapse. The fact is that natural ceramics has a porous structure. Moisture penetrates inside the pores, which freezes and destroys the material at subzero temperatures. This happens very quickly due to numerous periods of freezing and thawing. Metal tiles have no pores, so the negative impact of frost and thaws is not scary for her.
- Low specific gravity. Each square meter of Claudi metal tile weighs about 5 kg, bituminous tiles - two, and ceramic - 8 times more. For old buildings, this factor is very important, since their walls and foundations no longer have the proper strength. The use of new material allows you to extend the life of old structures, which is very serious when it comes to old buildings that have important architectural or historical significance.
Material Features
In the photo of the Claudi metal tile, the main highlight of the section is visible: the material consists of several layers:
- The basis for the manufacture of paintings of this type of roofing is galvanized steel.
- First, an aluminum-zinc passivating layer is first applied to the steel base, then it is coated with a primer.
- The last to be applied is a specially developed substance - a special polymer. So that the coating can withstand weather and natural factors, its thickness should not be less than 35 microns.
On the final layer there are irregularly shaped spots. They are very similar to clouds (in English - cloudy), which explains the name of the material.
On the back of the sheet there is the same coating as on the outside.
Coverage description
The colors of the Claudi metal tile are all shades of brown and red with smoky spots of smooth shapes. Moreover, the tan gamma was chosen specifically to imitate a natural coating of unpainted burnt clay. What is noteworthy, this material has one feature: when viewed from different angles, the color of the coating looks a little different.
As for the profile, the metal tile is available in three versions:
- "Maxi".
- "Super Monterrey."
- Monterrey
The most expressive is the second option.
For the convenience of working with the material, the sheets are still cut at the factory at such a length that is suitable for covering the roof of a particular building. This figure can range from 50 centimeters to 8 meters. An important detail : the shade of the products in each individual batch may slightly differ from the plates from the others, therefore, in order for the roof to have the same surface color, you need to purchase material from one issue and in sufficient quantity.
Specifications
The main features of the Claudi metal tile are the following indicators:
- The coating used is a special polymer.
- The thickness of the metal is 0.45-0.7 mm. The choice of basis in each case depends on how thick the final product should be.
- The thickness of galvanizing is 275 g / m 2 .
- The plates have a matte smooth surface.
- The service life while maintaining the appearance is 10 years.
- Corrosion can occur only after 30 years (manufacturer's warranty).
The basics of standardization
Judging by the reviews, the metal tile "Claudi" is in demand in the market of materials for roofing. The popularity of the material is due to its high performance, beautiful appearance and excellent quality. Moreover, in order to ensure product quality, the manufacturer - ArcelorMittal - systematically conducts tests to verify compliance with ASTM, ISO, ES. The material is checked for the following characteristics:
- The elasticity of the polyurethane coating and adhesion to the base.
- Percentage of scratch resistance.
- Corrosion resistance.
- Resistance to UV radiation.
Subtleties of installation
The laying technology of the Claudi metal tile is the same as the metal tiles of other types and brands. First of all, they install the rafter system, then lay the vapor barrier, waterproofing, and, if necessary, insulation. Next, arrange a crate of wooden bars. Before work, wood materials are treated with antiseptics and antipyretics. The bars are fixed only with the help of special screws with sealing washers.
An important detail : if during installation it is necessary to cut off part of the sheet, the cut line must be covered with paint - this will protect the metal base from atmospheric moisture, which is fraught with destruction of the roofing material.
In addition to the main canvas, when arranging the roof for the highest quality result, you will need to use other elements - ridge, wind and cornice parts. And with the ridge elements you have to work very carefully - you must definitely set the ridge plank of circular cross section. These products are equipped with plugs. For their fixation to the ends of the roof using screws. If a flat bar is installed on the ridge, the plugs are not installed, but insulation material is laid under the roof covering on the ridge. Lastly, a drainage system is mounted.
