Advantages of double-layer asphalt tile in the future development of tourism industry, roof system materials tend to have different styles, and the requirements for roof building materials are higher and higher. A kind of roof material can experience different styles, which can be said to be in the limelight. Moreover, the drainage and heat insulation performance of the roof are improved. Advantages of asphalt tile: it has various shapes and wide application range. Second, thermal insulation. Third, the roof load-bearing light, safe and reliable. Fourth, the construction is simple and the comprehensive cost is low. Fifth, it is durable and free from worry of breakage.

In the middle and late Western Zhou Dynasty, tiles were widely used; By the Eastern Zhou Dynasty, people had begun to carve various exquisite patterns on the surface of tiles for decoration; In the Western Han Dynasty, obvious progress was made in tile making technology, so that the tube tile with circular tile was simplified from three processes to one process, and the quality of tile was also greatly improved, which is called “Qin brick and Han tile”. Tiles usually have the functions of waterproof, heat insulation, sound insulation, heat preservation, shading and decoration. Clay tiles were mainly used at the beginning, and then glazed tiles, celadon tiles, asbestos tiles, cement tiles, synthetic resin tiles, color steel tiles and asphalt tiles were developed.

The advantage of double-layer asphalt tile is to firmly fix the asphalt tile with nails. The whole blade of the third layer of asphalt tile shall be cut off, which is staggered with the second layer of asphalt tile, and the bottom edge of the asphalt tile shall be flush with the top end of the decorative joint of the second layer of asphalt tile. Then, the whole asphalt tile is laid down in turn. Do not tear off the plastic seal behind the tiles. The plastic seal is only used for packaging to prevent mutual adhesion between tiles. The shadow caused by color difference is the design of the tile itself. The tile itself has self-adhesive, so that the tile can be pasted naturally under the sunlight after paving.
