The products related to asphalt felt tile are: 1) asphalt tile. Asphalt shingles have been used in China for decades and there is no standard. Its production and use are similar to cement glass fiber tile, but asphalt is used as binder. It can nail and saw, which is convenient to use. However, due to the rise of asphalt felt tile, its application scope is becoming smaller and smaller, and because the thickness of the tile is almost 1cm, although glass fiber and wood chips are used as reinforcement filling, it also feels that the cost is too high. 2) Fiberglass tile? glass fiber reinforced tile 。 This is a large category of products, including glass fiber reinforced FRP tiles, glass fiber reinforced cement tiles and rhombic clay tiles. Glass fiber reinforced FRP tile is reinforced by glass fiber and coated with epoxy or polyester resin. Most common sunshades are made of this material. Glass fiber reinforced cement tile (or rhombolite tile) is reinforced with alkali resistant glass fiber, and the outside is coated with cement mortar (or rhombolite). This kind of material is also called glass fiber reinforced cement (GRC) products. In addition to cement tiles, there are other products, such as bathtub, doors and windows, etc. Similar to the above asphalt tiles, the cement tile is a rigid wave tile with large size, and its length and width generally exceed 1m. 3) Asphalt roofing shingle. This is a kind of sheet material with glass fiber and other materials as the tire base as the reinforcing layer and cut into a certain shape after being produced according to the production mode of asphalt waterproof coiled material. This kind of material is actually flexible, which is different from the first two products. Calling it tile is actually a borrowed noun, so its English name is shingle instead of tile. This kind of tile is made of glass fiber as reinforced tire base, oxidized asphalt or modified asphalt as coating material, and the upper surface is made of various coarse-grained colored sand as spreading cloth. It is paved on the roof in the way of overlapping. It can be nailed and adhered. The mass of waterproof layer per M of roof is 11 kg (if it is lighter, the asphalt thickness is not enough, which may reduce the waterproof effect)? It is obviously much lighter than 45 kg? M of clay tile waterproof layer. Therefore, the bearing requirements of asphalt felt tile on the roof structural layer are lower, and the construction is easier. Because of this, many European and American companies produce and sell this product, such as soprema and bardoline in Europe, Owens & Cornings in the United States, etc. they have successful experience in the production and application of this product.
