Asphalt shingles, also known as colored asphalt shingles, are made of natural colored sand or natural rocks directly crushed and processed with asphalt materials. The color is natural, close, color-preserving forever, and beautiful in color. Asphalt shingles can be divided into three types according to the source of the base material, namely, path asphalt, oxidized asphalt, and modified asphalt. Path asphalt has low melting point, heavy oil content, volatile, low cost, and good viscosity. It is mostly used for asphalt road configuration. Oxidized asphalt is also called No. 10 asphalt. It has good temperature resistance and is not volatile. It is also called solid asphalt and has good aging resistance. , The use time is long, and the modified bitumen is mostly used for waterproofing membrane.
The laying of asphalt shingles must be laid in sequence. Along the gable and cornices, ensure that the first layer of asphalt shingles is aligned with the edges of the initial layer of asphalt shingles. The asphalt shingles must be laid precisely, but no squeezing occurs between the shingles. The laying of the first layer is the key point. During the laying process, it is necessary to check whether the asphalt shingles are aligned with the required horizontal line. The side of the first asphalt shingle on the second floor should be staggered by half from the side of the previous asphalt shingle. leaf. Next, the first one of the three-layer asphalt shingles should be cut and the entire blade should be cut so that it is staggered from the first one of the second layer of asphalt shingles, and the bottom edge of the asphalt shingle should be the same as the decorative joint top of the second layer of asphalt shingles. Look at the same level.
