Everything You Should Know About Slate Tile

Many people must have seen the slate tile, but you don't understand it. Let's approach the slate tile together today.

What is slate tile?

Natural slate tile, also known as shale tile and bluestone tile, is a popular term for natural slate as roof tile, and the standard term is tile. According to textual research, in Ziyang County, Shaanxi Province, China's "hometown of tile and slate", slate has been used to cover the roof since the pre-Qin period, and many simple and beautiful slate folk houses have been well preserved. Due to the backwardness of the processing industry, for hundreds of years, slate has been deeply processed in European and American countries and widely used in building roofs. From museums and churches to high-end buildings such as city halls and castles, black slate roof has become one of the symbols of European architecture.

Characteristic

The material of slate tile is not slate but natural slate. Slate is a kind of natural stone like marble, granite and sandstone. Its biggest feature is that it has natural cleavage and can be split manually or mechanically. Therefore, the surface of building slate products has not been mechanically polished and has the characteristics of ancient and natural surface. Due to different material characteristics and metamorphism, some high-quality materials in slate can be processed into roof tiles. These slate are often called tile slate. Slate that cannot be used as tiles is processed into decorative panels for wall and ground decoration.

It is also a kind of building slate. Tile slate can be used as veneer slate, while veneer slate can not be used as tile slate. What is the reason? First of all, we should know the characteristics that high-quality slate must have: good splitting performance, good flatness, small color difference, high blackness (the same for other colors), high bending strength, low calcium, iron and sulfur content, low ignition loss, good acid-base resistance, low water absorption and good weather resistance. Poor flatness, which can not meet the requirements of neat and proper tile hanging construction; Without good material characteristics, it is impossible to maintain a service life of more than 100 years without fading, weathering and rust.

Possibility of application of 10 kinds of slate tile roofs

🔸Double slope roof: This is the most common roof type, which is composed of two symmetrical or asymmetric planes. It can have eaves or not. The roof is also very practical: easy to build, well drained, easy to ventilate, and suitable for most construction projects.

🔸Four slope roof: this kind of roof is also very common, and the structure will be slightly more complex, consisting of four inclined planes. Because there is no gable to produce wind resistance, this roof is especially suitable for areas with strong wind.

🔸Dutch roof: it is very similar to double slope roof, but there are two more obvious inclined planes on the other two sides. In addition to improving natural lighting and adding additional space, these two planes can also become access to the attic.

🔸Monsha roof: this kind of roof is very common in Paris. Its four sides are composed of eight planes. The four planes below are very inclined, but the four sides above are almost flat, providing space for the lower part of the roof.

🔸Flat roof: most flat roofs are not completely flat, but slightly inclined. This slight slope is conducive to drainage.

🔸Single slope roof: This is a unique design, which provides space for large-area windows and high clearance.

🔸Butterfly roof: this roof is composed of two planes inclined to the central ridge, which can provide sufficient lighting and ventilation, but the structure of drainage ditch must be designed to avoid leakage.

🔸Compound inclined roof: it can be regarded as the deformation of double slope roof, with two planes with different slopes on both sides. This makes better use of the interior space of the attic.

🔸Dormer roof: this roof is characterized by dormer windows that illuminate and increase the existing space. They protrude from the roof and create useful space outside the roof, providing additional natural lighting and ventilation.

🔸M-shaped roof: it is composed of two or more double slope roofs.
