Asphalt shingles are a new type of extremely valuable waterproof roofing shingles. As asphalt shingles are particularly popular among the public, uneven products have appeared on the market. Choosing the right kind of asphalt shingles will have absolute benefits for future roof repairs. So, how to identify the quality of asphalt shingles? The following is a detailed introduction by the asphalt shingle manufacturers and everyone.
The standard name of asphalt shingle is glass fiber asphalt shingle, which is based on glass fiber, with asphalt and colored sand attached to the surface. Therefore, these raw materials are the key influencing factors to identify the quality of asphalt shingles.
Asphalt shingle quality inspection point: colored sand
The most related to the aesthetics of asphalt shingles is the quality of colored sand. Good colored sand can keep the color lasting through exposure to the sun, wind and rain. Some small manufacturers use low-temperature acrylic paint for dyeing, although the color is bright when they are bought, but the color fades very fast; most domestic manufacturers use high-temperature sintered sand, most of which are domestic sintered sand, with average color retention; ceramic sintered sand is of high quality. The cost is relatively high, and a few manufacturers will choose it. Ornice asphalt shingles are made of colored sand from French CARLAC, which is sintered at a high temperature above 800°C. The color is bright and stable, and the color is not easy to fade.
Asphalt shingle quality inspection point: asphalt
Taking into account the climate change throughout the year and the difference in light intensity, the selection of asphalt shingles is particularly particular. Currently, the raw material asphalt on the market mainly includes road asphalt and modified asphalt. Road asphalt is not resistant to high temperatures and volatile, but its low price will be appreciated by some manufacturers; modified asphalt has good aging resistance and is not volatile, and is the material of choice for qualified asphalt shingles.
Asphalt shingle quality inspection point: glass fiber felt
Fiberglass felt refers to a non-woven fabric made of glass fiber monofilaments interwoven into a network and cured with a resin binder. Tile manufacturing mainly includes three types of raw materials: composite tires, polyester tires, and glass fiber tires. Among them, the composite tire obviously has a layer of grid, and the temperature resistance is poor. The upper and lower layers of the produced tile are easy to tear; the tile based on the polyester tire is very easy to weather and rot under high temperature conditions, and has no water resistance; good quality Asphalt shingles are made of glass fiber tires, which can adapt to various climatic conditions. It can be used in places with low temperature of minus 35 degrees and high temperature of 90 degrees without deformation and no damage, excellent waterproof performance and long service life. The glass fiber mat with a mass per unit area of 90g/m2 is the basic requirement of the national standard. The Ornice asphalt shingle uses a tire base of 95g/m2 produced by Jiangsu Changhai.
When purchasing, you can distinguish three types of tiles from the thickness. Generally, the thickness of the glass fiber asphalt shingle is controlled at the national standard of 2.6mm, which is thinner and lighter than the other two types of base tiles.
The above is the method of identifying the quality of asphalt shingles. I hope everyone can choose the best quality asphalt shingles.
