According to RSI Magazine's recent report, the new type of roofing waterproof material in the United States has been growing at an alarming rate. It has developed into a new type of roofing waterproof material that deserves our attention and is now being comprehensively introduced for the reference of our waterproof material industry peers.
1. Surprising growth in new waterproof materials for single-story roofing It is well-known that there has been little change in the new roofing waterproof material technology in the 100 years before the 1960s.
All countries in the world use hot-tacked asphalt to lay 3 to 4 layers of bituminous membranes as a waterproof layer for new roofing waterproofing materials. This is called new waterproof material for laminated roof (BUR). The United States is no exception. With the advancement of the chemical industry, the rubber and plastics industry has made significant technological progress, providing a material basis for the development of new waterproof materials for single-layer roofing and new waterproof materials.
In 1962, the American Carlyle Company laid a new type of EPDM roofing waterproofing membrane on the roof of the Chicago International Airport, setting a precedent for a new type of single-layer roofing waterproof material. Since then, new single-layer roofing waterproofing materials based on rubber and plastics have appeared in the field of new waterproof materials for low-slope roofs.
However, the initial development of new single-layer roofing waterproofing materials has been slow, and people are still habitually keen on more reliable laminated roofing new waterproofing materials. The world resource situation in the 1970s brought opportunities for the development of new waterproof materials for single-story roofing.
First of all, the 1973 Arab oil embargo resulted in soaring oil prices and a shortage of new waterproofing materials for roofing of high quality roofing. At the same time, higher energy prices have increased the demand for new thermal resistance roofing new waterproof material systems.
This makes the new waterproof material for single-layer roof more attractive because it can be directly laid on advanced insulation boards such as polyisocyanurate and expanded polystyrene. At that time, some functional problems occurred in the new type of waterproof material for laminated roofs, such as double-layer failure and foaming on polyurethane insulation boards.
In spite of this, the new roofing waterproof material contractor was still cautious about the use of monolayers, and the new waterproof material for flat roofs was not modified asphalt. In 1997, it accounted for only 10% of the new waterproof material market for low slope roofs. Since then, the material quality of new-type waterproof materials for single-story roofs has been continuously improved, construction technology has been correspondingly improved and perfected, and new-type waterproof materials for single-layer roofs have been rapidly and continuously growing, increasing to 25% in 1984 and increasing to 48% in 1987. Over half of the year, accounting for 54% of the market, has become a new type of roofing waterproof materials.
